By Asoka Seneviratne –
As a country located 9- degree north of the equator, Sri Lanka is blessed with abundance of sun. Sun shines over Sri Lanka with vengeance to the point of feeling burning hot for most of the year. Yes, sun is everywhere. According to Asian Development Bank, a square meter of PV solar panel with 5.7 hours of sun can provide 4.6 KWh of power. That works out to be 807 watt-hours of solar power with a PV panel of 3 ft X 3 ft size every hour.
Another report by the ADB put the potential available capacity of solar power of SL at 16 GW or 16000 MW. This is huge and free power all year. Currently Sri Lanka houses about 750 MW of solar power or a pathetic 4.6% of available solar power.
Sri Lanka currently produces a total of about 5100 MW of power which 58% comes from renewable sources and the rest comes from fossil fuels. In other words, SL produce 2142 MW of power from crude and coal.
Per IRS, one barrel of crude oil produces about 1.7 MWh of power. At $80 per barrell of crude, the cost of producing 1.7 MWh of power runs $80. As we produce 2142 MW of power from crude at peak, cost of our fossil fuel power per one hour is $ 100800.00, assuming we generate at the rate of 2142 MW rate.
Assuming we need to generate fossil fuel power at this rate all year, the cost to the nation per year for crude runs about $ 870912000.00 or 870.9 million US$.
Now if we import crude at $100 per barrel (US$ 20 more per barrell) the cost to the nation per hour will be $ 126000.00. Annualized, cost to the nation will be $1,088,640,000.00 or 1.088 billion US$. Per year
Now, given the corrupt, non-transparent nature of our politics plus awarding no-bid contracts, they can potentially pocket $ 217,728,000.00 or 218 million US$ per year merely from CEB oil imports. This is assuming we only use crude not a mixture of crude and coal. Nevertheless, the number is similar and the cost to the nation is mammoth.
The actual cost of CEB crude imports are higher per CBOSL (but close enough) running to over a billion dollars.
Now going back to Solar, it is widely assumed that the installed cost of a 40KW PV solar panel is Rs. 7 million. Given the 2142 MW rate CEB produce at peak, this works out roughly at Rs 374850 million or Rs. 374.85 billion to install solar to match that capacity. Or $1.25 billion to install PO Solar on a large scale. This cost is very close to the cost of importing crude by CEB per year. The actual cost might be a little higher, but these are ballpark numbers.
It is widely believed that the average life span of a PV solar panel is 22-25 years, one can imagine the gigantic amount of precious dollars our nation can save! Imagine how many things we can do with all these saved billions year after year!
Better facilities for schools, better roads to our villages, better reserves, better budget deficit, better contribution to the environment, and most importantly using that God given sun that we consider far too hot to real better use.
Now lets take a step further. If each household is installed with a 5 KW PV panel at a cost Rs 1.2 million. Return on Investment is 4 years and 6 month. And the life span of a PV system is 22 – 25 years.
It is assumed monthly payback from the CEB is about Rs 25000.00, a substantial saving for an average family.
Now let’s look at another part of the world where the Sun is not an everyday blessing but leaders are; Europe.
The largest solar producers are Netherlands, Germany, Denmark, Belgium, Luxembourg, Estonia, Spain, Greece, and Malta in that order. Per capita use of Netherlands and Germany are 1044 watts and 816 watts and coming down to others, respectively. Given Germany’s population of 83.8 million, their current solar capacity is 68300 MW of solar power.
At solar use of 416 watts per capita with an 8.8 million population, Portugal produces 3660 MW of solar power currently. None of these countries are even close to the level of sun we in Sri Lanka is blessed with.
But sunny Sri Lanka produces a mere 750 MW per statics of SL government. This is unacceptable given that previous governments have wasted borrowed billions on non-sustaining projects.
Our brainless leaders built with borrowed money airports with no planes, ports with no ships, conference halls with no meetings, roads with no vehicles, started airlines ( Mihin Air) with no demand, build roads with no parking spaces so vehicles park on the side walk and pedestrians walk on streets, level crossings with no warning lights so vehicles can clearly see them specially at night (turning them into death traps) and tall beautiful structures depicting national pride ( Nelum Kuluna at $108 million) and so on and so forth but never Solar Panels.
Gota appointed a minister for Batik, but no minister to drive Solar Power initiatives and incentives.
Starting from Colombo airport and driving around in Sri Lanka over to the dry zone with more burning son, one can hardly find a streetlamp with a solar panel on top. Whatever streetlamps we have are powered by the grid for the largest part. Gota installed some solar powered streetlamps near parliament but not sure how many of them are still working off solar.
Village after village in remote areas can do tens of thousands of small PV Solar panels, all free. All what is needed is smart leadership.
In my view there is simply no excuse for SL not to have solar powered streetlamps at minimum. That is why we elect hundreds of national, provincial and local leaders and take care of them. We leave these vital decisions to them but after being elected they are busy hounding for commissions, not public needs, of course there may well be exceptions, but the powers above may have a different agenda, so they too become helpless.
It all boils down to the caliber of leaders we elect. Are they smart with wisdom or just crooks bent on milking our wealth? Now we know after 76 long years.
This is why we need a change in Leadership badly. The same old will not work.
Finally, today I hear AKD will be revealing their manifesto or agenda soon. That is good news.
But I hope they are not going to spell out a list of promises but a properly laid out robust system change with afresh constitution with proper checks & balances, transparency and oversight. Such a system must be robust enough to sustain itself not depending on the caliber of leadership we elect. i.e Ranil postponing elections and more.
How to create transparency in spending, how to insulate the law enforcement and the judiciary from political interference, how the judges are appointed to insulate them from political interference, how the government services will be more like 21st century and free from corruption, how the police top brass are appointed to function true to their oath to serve the public without fear or favor, what will the legislative agenda and priorities, how to recover the loot and hold those robbed our nation accountable, how to attract foreign and local investment, how to rid of crony capitalism, how to rid provincial and local bodies of corruption, how to repay national debt, how to restore education in schools and minimize tuition class dependency, how to expand university and vocational school system, where the money will be coming from for these investments, how to prevent two government banks from turning into personal money pots of the leaders, how to cut the massive budget deficits, how to expand the tax base without burdening the middle class while maintaining a positive business climate, how to expand our forex reserves, how to stop MP’s being auctioned, restore the dignity of the parliament and the executive branch and finally to create a government that serves the public honorably but not to themselves.
A good manifesto should address all these national issues in detail, giving priority to establishing a long-lasting robust system than depending on the personalities in power. Leaders can and go but the system must prevail even under a dictatorial leader. Such is a good constitution and hope AKD’s team is up to it.
A recent case in point in the global arena. For centuries the US constitution created a Democracy that was the envy of the world. In fact, if I am not mistaken, US constitution is the longest running written democratic constitution of the world. But on January 6th of 2021, former President Trump instigated a violent uprising to ignore the election and remain in power.T he world was taken by surprise unable to fathom how this rock-solid American democracy lasting over 225 years was on the brink.
But the robust democratic institutions and the built-in safeguards of the constitution rushed into action and protected this much respected democracy from collapse. A good well-crafted constitution can sustain its Democracy against all evil.
AKD and his untested team have a lot of arduous work to do. May they be blessed with wisdom for this mammoth task of nation building from scratch!

“Another report by the ADB put the potential available capacity of solar power of SL at 16 GW or 16000 MW. This is huge and free power all year.”
Not quite “all year”. One has to factor in that there are two monsoons, and there are intermittent clouds even when it’s not raining. Solar power is only good for about 60% of daytime. Sri Lanka is not the Sahara Desert.
“It is widely believed that the average life span of a PV solar panel is 22-25 years, “
Yes, but they don’t suddenly switch off in the 22nd year, they produce less and less power over time. Even in 5 years, there is loss of output.
“Now let’s look at another part of the world where the Sun is not an everyday blessing…. Germany..etc.”
The author has left out the fact that electricity charges are much higher in these countries than in Sri Lanka. “electricity prices in the second half of 2023 were highest in Germany (€0.4020 per KWh), Ireland (€0.3794 per KWh), Belgium (€0.3778 per KWh) …”
If the CEB charged 150LKR per unit, yes Sri Lanka could use large-scale solar. But unlike Germany, SL is a bankrupt Third World country….
We a cannot compare apples and pears.

UK is less sunny than SL with only a few daylight hours in the Winter months & even in summer, it can be cloudy most of the time, yet solar panels (& wind farms) can be now seen in abundance. Property developers are required by law to provide a certain percentage of the houses built to be equipped with solar panels in line with the ‘Green’ agenda. A solar power system with a 5 kwh battery would cost under £8k fully installed in UK which will provide electricity even when there is no sun. A few years ago, I saw solar panels installed on the floating huts on Late Titicaca in remote Peru, which was enough to power small fridges, TVs, fans, in addition to the lights.
A visionary govt. would have found a solution to rising electricity costs years ago before bankruptcy. SL was facing electricity breakdowns & droughts causing power cuts as long as I can remember & any competent govt should have investigated the potential of solar & other ‘sustainable’ energy sources, instead of investing in highly polluting coal fired power plants which are now banned. Even the coal power plants are frequently breaking down, if I am not mistaken, making them unreliable more than the weather. There is no excuse for incompetency & corruption of our politicians.

Raj,
This article makes things clearer:
https://reneweconomy.com.au/rooftop-solar-meets-80-pct-of-states-electricity-demand-in-middle-of-winter/
“That is one reason why coal fired generators are seeking to exit the system, or source large state government subsidies to stay on, as Origin Energy has successfully negotiated in NSW.”
The problem is the way the National Grid is set up. It cannot function properly without a stable Base Load.
Even in the UK, “As of 2023, over 14.4 gigawatt (GW) had been installed, a third of which was rooftop solar.[3] Annual generation was 14 TWh in 2022 (4.3% of UK electricity consumption) “
Solar with batteries is OK if you want to be totally independent of the grid (as in Lake Titicaca), but in a place like SL, where it can rain for days on end, the batteries won’t last long.
/
Raj-UK / August 13, 2024
OC
It rains frequently in UK too & snows as well. Solar panels need no maintenance & the battery is not exposed to the outside environment. An average UK household is expected to recoup the cost in under 8 years
Considering the frequent power cuts, particularly, during a drought when electricity is needed most, as well as, the high cost of electricity, I think it makes sense for SL households to go solar. With an ever increasing strain on the national grid, SL should consider all forms of energy sources & make coal power plants redundant ASAP. A nuclear option is not for SL but I am sure there are natural resources to compliment the hydro power generation. Reducing household dependency on the national grid with solar power is a reasonable option.

Hello Raj-UK,
And you didn’t even mention the profusion of Wind Farms in the UK either. I used to live in Oswestry near the Welsh Border and there were Wind Farms all over. Cross over the English/Scottish Border and you will see many more.
Up here in the hills near Gampola we have plenty of Wind for the Turbines. A mix of Solar and Wind Farms would provide a fair percentage of Power needs in Sri Lanka. But only if the Politicians ditch the “what’s in it for me attitude”.
Best regards

Raj-UK / August 13, 2024
LankaScot
I agree. I did mention wind farms but I wanted to focus on solar panels where citizens can do their bit to reduce SL’s dependence on fossil fuel dependency, if there are incentives by the govt. to reduce the costs associated with solar power generation. My friends complain about exorbitant cost of electricity & frequent disruption of supply, therefore, if the govt. is unable to invest in large scale renewable energy sources, at least the citizens can benefit if solar panels & batteries are made affordable
As you probably know, there have been protests from the ‘countryside alliance’ & such like in UK about wind farms ‘destroying’ the landscape but the benefits are now being realised. I believe a remote Scottish village is even profiting from windfarms by selling excess electricity to the grid. Apart from offshore wind farms, even the energy from ocean currents is being harnessed. A third world country like SL may not have the resources to invest in cutting edge technology but that doesn’t mean SL has to depend on obsolete technology either. This is about a prudent govt. planing for the future but with the current yobs with no understanding of science & technology running the country, SL is backward in every way. Then again, even Trump is a climate change denier, yet, he survives as a politician in a most advanced country thanks to uneducated citizens.

My grouse is with rooftop solar as in Sri Lanka, not solar in general. :A power source must be
1.Cheap
2 Reliable
3 As pollution-free as possible
4 Responsive to demand
5 Compatible with distribution infrastructure
Only Hydro meets most of the above criteria. However, it’s not reliable when rains fail. It makes up more than 60% of Sri Lanka’s renewable output. Rooftop solar was about 18% (3% of the total)
Large-scale solar with pumped water storage is the best option, because it can perform even at night. In addition, it uses rotating turbines which provide the flywheel effect for frequency stability. Rooftop inverters cannot provide this important function. This IEEE paper explains the problem. One cannot accuse the IEEE of wanting commissions. This is purely a technical problem.
https://ieeexplore.ieee.org/abstract/document/8709570
Rooftop solar as in SL doesn’t even perform during daytime power failures. Adding batteries makes it totally uneconomical compared to CEB charges.
In my opinion, our problem is not a shortage of power, but unnecessary wastage. Why do we live and work in air-conditioned concrete-and-glass boxes? Building codes should be revised to allow sufficient ventilation. Natural light should be used as much as possible. There are things called “light pipes” which do just this.

LankaScot / August 13, 2024
Hello OC,
My friend in the Village (Hardware Store) has a 10kW 3 Phase System connected to the Grid. Last time i looked it was working well. His problem is getting payments from the CEB. His system is not used for his own Domestic Power. Rooftop Single Phase PV systems can provide Frequency and load Stability using Batteries and Super Capacitors. https://ietresearch.onlinelibrary.wiley.com/doi/pdf/10.1049/iet-rpg.2019.0873
These systems are very expensive and I haven’t seen any in Sri Lanka. So you are right it puts Solar beyond the pockets of most Sri Lankans.
My Father worked on a Pumped Storage Construction (Thyssen GB) in the early 60s, Ben Cruachan https://www.visitcruachan.co.uk/
This sort of system would work well in Sri Lanka.

LS,
The government can only invest in renewable energy if people are willing to pay at the same rates as, say, in Germany. They aren’t.
Actually, I do have a small solar installation. A couple of hundred Watts with some ex-laptop batteries just to keep the router and lighting going during power outages. No inverter.

RBH59 – Isn’t eating rice cheaper and healthier? As a source of carbs? While leaving bread and bakery products for occasional use? I think in terms of food we need to promote a healthy diet balanced in calories and nutrients. I’d be more inclined to develop fisheries industry as a source of proteins, while optimising paddy farming for dietary requirements of carbs. Corn I believe is among the top crops that cause greatest amount of deforestation, which I’d avoid at all costs. What are your thoughts?

Why Doesn’t Sri Lanka Have Hundreds Of Thousands Of Solar Panels?
The answer is obvious. We have uneducated corrupt politicians who are not interested unless they have their pound of flesh but that’s not all. The Elect Board officials from top to bottom also have to be ‘bought’ therefore, the investment in solar panel industry is probably not feasible. A friend who was renovating his house wanted solar panels installed but was discouraged by the Elect. Board
If memory serves me right, a politician had commented not so long ago that Oxygen cannot be eaten. If that is the level of education we can expect from the average SL politician, advancement in technology would be rocket science to their tiny brains which are capable of only street cunning. Can we expect the country to progress with such a bunch of yobs?
Cont.
/
Raj-UK / August 11, 2024
Cont.
On a complimentary subject, I understand that only Electric Vehicles, not even ‘plug in’ hybrids, are allowed to be imported but there is no infrastructure for public charging points, bearing in mind that the average battery range is about 200 miles at best, depending on favorable conditions (despite some manufacturer claims of over 300 miles). Accordingly, a motorist returning from N’ Eliya maybe taking a risk with a 50% battery charge but charging from a domestic power source would require overnight charging, whereas, a public ‘fast charger’ should provide 80% charge in about 40 minutes. The joke is approx. 42% (according to the author) of the electricity generated is from burning fossil fuel, which would be from polluting coal fired generators. So, what is the big idea of promoting ‘clean’ EVs? What is to be done with the ageing polluting vehicles already on the road?
Furthermore, the life span of a EV battery is about 10 years, therefore, most hybrids & EVs imported as used vehicles will soon require replacement but is SL prepared for the disposal of these batteries without harming the environment or even aware of the danger in handling them incorrectly? Do we have a political party that addresses these issues in the name of progress?
/
old codger / August 12, 2024
Raj,
“A friend who was renovating his house wanted solar panels installed but was discouraged by the Elect. Board”
I am no fan of the CEB, but there is good reason for this. In SL, most rooftop solar doesn’t have storage, as opposed to large-scale solar, which does. So, power is produced only when the sun shines, and not at night or rainy days. A good deal for the panel owners, but a bad deal for ordinary consumers. Why?
Because the CEB must run idling generators in daytime to pick up the load at night (they can’t be switched on and off at will, except for the hydro ones). Who pays for idling generators? The guys who don’t have solar panels, of course.
In SL, buying/replacing batteries for domestic solar panels makes the whole exercise uneconomical.

“……….We have uneducated corrupt politicians who are not interested unless they have their pound of flesh but that’s not all. The Elect Board officials from top to bottom also have to be ‘bought’ therefore, the investment in solar panel industry is probably not feasible….”
Both above sentences are absolutely valid. There is no argument about the first sentence but the fact in your second sentence is the elephant in the room in SL now. People don’t see it, don’t discuss it and don’t even acknowledge it. What is that? The most despicable level of corruption unleashed by those who have the most elitist academic qualifications in the country!! There are so many rotten to the core corrupt, highly educated people at very important nerve centers in the SL bureaucracy who probably can outrun those common uneducated corrupt politicians in a flash! CEB is one such most rotten institutions in the country with so many bad eggs with BSc Engineering degrees. Trust me, they ALL can be bought, depending on the price you offer them! The difference is the price tag of the individual who has to ‘pass’ the project you are going to start. I wonder why Asoka is not aware of this stark truth!

Hello Asoka Seneviratne,
Here may be part of the reason for lack of large Developments – https://www.themorning.lk/articles/cfrfThq4x6i5NNuUeGdU
Why does an FDI Company have to pay Rs 700 Million for a licence?
“According to the SLSEA, the one-time permit fee for issuing the energy permit for projects up to 10 MW is now Rs. 500,000 per MW of capacity. For projects exceeding 10 MW, the fee is Rs. 1 million per MW”.
I have never been able to understand Sri Lankan pricing. I go into a Supermarket here to buy a Diluting Juice – 2 litres (Plastic Bottle) for Rs 3300. The same Juice price for half a litre (in Glass Bottles) Rs 750. So I can buy 4 Glass Bottles for Rs 3000 and the 2 lire Plastic one for Rs 3300. Where is the logic?
So where is the Incentive to build large Solar Systems? The Government obviously doesn’t want them. Why, maybe you can tell us?
Best regards
In Europe or the USA buying a bigger amount gives you a discount compared with smaller amounts.

Well-articulated write up on utilization of solar energy. Politicians should be in shame after reading this brilliant information by Mr Ashoka. The benefits of deploying solar panels, particularly on rooftops, are undeniable. Yet, governments have consistently turned a blind eye to the implementation of rooftop solar solutions. As long as corrupt and cunning politicians continue to hold power, our country will remain impoverished, with more citizens falling into hunger. The government has exacerbated the situation by creating fuel shortages and threatening the populace with food scarcity, only to justify increasing electricity bills. Even in the wake of an economic crisis, politicians have refused to sacrifice their perks, instead indulging in an unprecedented spree of corruption—ranging from airport and aviation scandals to schemes involving the importation of crude oil and visa fraud, among many others.
There are over 10,000 government schools across the country, many of which have vast expanses of rooftop space. These rooftops present a tremendous opportunity to install solar panels that could generate clean electricity, feeding directly into the national grid. Such a project could significantly reduce our dependence on imported crude oil, a resource that has long been a curse on our economy due to its use in thermal power generation.
But the critical question remains: who will have the courage to challenge the status quo and make this vision a reality?

Hello Paramanathan K,
As one of my relations here said, “If there’s no money going in a Politician’s Pocket, it doesn’t get done” This was his response to my question about why the Offshore Oil in Mannar has not been developed. I suppose the same applies to the Solar Question?
However the Supreme Court seems to be taking a different view
“The Supreme Court in a landmark judgment held that the belated position taken up by the Ceylon Electricity Board (CEB) and its refusal to issue a permit to operate a solar power electricity generation plant in Vavuniya was contrary to the law and both the CEB and Sri Lanka Sustainable (SLSEA) Energy Authority have unlawfully and miserably failed in the performance of their duty towards the public in encouraging project proponents to harvest green energy sources” https://www.dailymirror.lk/breaking-news/SC-holds-CEBs-refusal-to-issue-permit-for-solar-power-plant-is-illegal/108-267671

If Germany in North Europe who gets such little son and even gets cheaper energy from Russia does generate over 68000 MW of solar power, it beats me to wrap my head around why sunny SL has far less than 800 MW with only only initial $ investment rather than draining billions of $ annually to import oil and crude.
Even India is among the top 10 countries of solar.
While watching the India / SL cricket last week, I was so sad to see the large R Premadasa stadium has no solar on the roof while cricket board is swimming with money.
Some of the cricket stadiums in the Caribbean are fitted with roof solar.
Why not invest SLR 1.2 million for a 5KW solar panel and receive SLR 25000 a month from CEB while receiving power at night to a household beats me. If this is not a win- win, what is?
The missing part is the lack of initiative and commitment by GOSL to drive this at full throttle!

Asoka,
Your statistics are rather doubtful.
“Even India is among the top 10 countries of solar.”
Solar Energy Represents 17% of India’s Installed Power Capacity, Overall Renewable Energy Surpasses 31% .
No country runs 100% on solar, not even the ones in the Sahara Desert. There are countries like Norway, Iceland, and Ethiopia which have almost 100% Renewable energy, but that is mostly hydro or geothermal.
“If Germany in North Europe who gets such little son and even gets cheaper energy from Russia does generate over 68000 MW of solar power, …”
Yes, but Solar power accounted only for an estimated 10.7% electricity in Germany in 2022,
Wind power provides about 50%, comparatively.
As I said before, no country has more than about 20% solar. As of 2024, solar energy constitutes approximately 9% of even China’s total energy mix.. Most renewable, even in the case of Sri Lanka, come from sources like hydro and wind.
It is a mistake to make a fetish out of solar power. It is highly variable and requires backup.
“Why not invest SLR 1.2 million for a 5KW solar panel and receive SLR 25000 a month from CEB while receiving power at night to a household beats me. “
It may be a good deal for a household, but the CEB has to keep generators on standby to supply the household when it rains for a week. THAT is the hidden cost of solar.

The CEB will have to keep a third of that capacity (assuming hydro gets boosted by the rain) idling all year just to take up the slack when rain causes solar to fall to zero for a week now and then. It is possible only if the consumers pay @ Rs 150 per KWh.

Lester – what about the over billion $ savings annually on can crude imports?

Asoka,
Solar & wind are intermittent. You still need a backup, for example, during the monsoon season. Solar by itself is definitely not feasible for manufacturing. Besides all this, Sri Lanka’s current grid is not equipped to handle excess energy fed back into it. Without proper energy storage systems, voltage fluctuations could cause blackouts. A better alternative might be nuclear energy: https://www.dailymirror.lk/opinion/Sri-Lanka-is-now-well-on-the-way-to-harnessing-nuclear-energy/172-284556

Hello Lester,
Some of the most advanced Countries in the World have had Nuclear Accidents. Winscale UK, Chalk River Canada, Chernobyl (Ukraine) USSR, Three Mile Island USA, Fukushima Japan and many more. Sri Lanka has great trouble keeping Norochcholai Power Plant working “It has come to light that no proper investigation has been conducted by CEB or Lakvijaya to understand why these units are failing continually and to decide on suitable interventions”. Have a look at the 2023 Report https://sangam.org/report-on-norochcholai-power-plant/
“Sri Lanka has identified nuclear energy as a clean and green energy” from your Article Link. There is nothing dirtier than Nuclear Waste.
So given the incompetence of the Sri Lankan Government to maintain the Power Station, do you think they can safely handle a Nuclear Power Station that has the potential to kill a substantial proportion of the Local Population?
Best regards

Hello Lester,
Did you not see OC’s comment about Pumped Storage and my reference to the Scottish Site Inside the Ben Cruachan mountain built in the 1960s?
Best regards

Asoka, for all I know Cochin international airport , Kerala is fully solar powered. ( see wikipedia for details)

Not sure whether this is coincidence or not. According to today’s news, Lanka Railways approved projects to install and maintain solar panels on roof tops.( apparently there are 300 stations under SLR )

It makes sense in given contexts. Importing the technology wholesale is costly.
As an answer to the total energy deficit it still fall short.
Consumerism remains a major problem in the Third World.
