This article summarises the history of solar energy development in Sri Lanka that I have been involved with, over the past 40 years and my thoughts on the present situation in the country. As an active solar energy conversion researcher in both academia and industry (British Petroleum Research in London), I have seen the maturity of this technology since the late 1980s and started to promote it in schools and community events in the United Kingdom.

I then extended this work to my native country, Sri Lanka, in 1991, by initiating a UK-DFID (UK Department of Foreign and International Development) funded and BC (British Council) managed Higher Education Link (HE-Link) programme. This is how I met all renewable energy promoters in Sri Lanka. This article brings back my memories from the work done in collaboration with various people, starting in the late 1980s.

During the six-year HE-Link programme, I worked with several universities (Peradeniya, Colombo, Kelaniya, Moratuwa and Ruhuna) and organised conferences, seminars and public lectures in schools and government ministries. There were only two or three small solar energy companies at that time, struggling to do business, and they all joined together to promote renewable energy initiatives in the country.

Among many interested academics, senior engineers like Dr. Ray Wijewardane joined all these events, and I met three notable entrepreneurs working in this field starting in 1985. They were Lalith Gunaratne, Pradeep Jayewardene and Viran de Perera. These three friends, who were brought up in Canada, visited Sri Lanka for a holiday after their marriages and decided to stay in Sri Lanka and start a solar energy business. Their starting work was a mobile solar water pump, but about 80% of the people who were not connected to the national grid asked for solar lighting rather than solar water pumping.

Sir Arthur C Clark also gave them a good helping hand and they started to install small solar home systems in rural areas. They also started to import solar cells and assemble SUNTEC 36 W solar modules in the country, but due to various barriers from outside, that project had to be terminated. There were numerous barriers within the country itself. P remember a newspaper article that appeared in Sri Lanka titled “Solar Power Suitable for Lotus Eaters”. After all this fantastic work in the late 1980s, Lalith returned to Canada, Viran started an eco-tourist centre, and Pradip continued to work in the solar energy field.

Most of these entrepreneurs told me that the government authorities did not listen to them due to their vested interests. For this reason, I made the decision to promote renewables as a research scholar without any connection to a commercial company. This approach worked well, and I made two or three visits to Sri Lanka in some years delivering public lectures in ministries, universities and in schools. I also wrote numerous articles in the local press and completed many interviews on applications of renewable energy sources.

Solar home systems, at early stages, had about 50 W solar panels. These were combined with lead-acid batteries to store energy and provide 5-6 lights at night. This was also enough to power a black-and-white television for a few hours. Depending on the number of lights used, the cost of such a system varied between Rs 40,000 and Rs 60,000.

Meanwhile, the Ceylon Electricity Board also worked to expand the national grid under the country’s 100% electrification programme. As the national grid is available almost everywhere, the interest in small solar home systems gradually disappeared.

There were many people in the country involved in promoting renewables, and I was able to visit Sri Lanka every year to spend a few weeks at a time and work with numerous institutes.

I also personally met almost all Science & Technology Ministers, starting from Mr Bernard Soysa, and some Power and Energy Ministers to introduce renewable energy projects. Although the government’s take-up was slow, the private sector developed very rapidly, starting many new companies for solar system installation.

Gradually, the main interest turned to the grid-tied larger solar systems installed on freely available rooftops. With the “Soorya Bala Sangramaya” programme introduced around 2016, solar roofs began to be connected to the grid via “Net Metering”, “Net Accounting”, and “Net Plus” methods. A few years ago, a 5 kW solar roof used to cost about Rs 14,00,000, but today, the cost has come down to about Rs 9,00,000. Each 5 kW solar roof installed in the country removes the need to burn 7.5 metric tons of imported coal, introducing numerous health and economic benefits to the nation, including reducing the country’s huge import bill.

I also collaborated with the ex-chairman of the Sri Lanka Sustainable Energy Authority (SLSEA), Prof. Krishan Deheragoda, to bring two 500 kW solar farms to the country, introducing larger solar farms. After promoting renewable energy over four decades, I am pleased to see numerous large solar energy systems beginning to appear in the country, including “Floating Solar Farms”.

The current government’s interest in indigenous, hydro, solar, wind, biomass and bio-gas energy, as well as the contributions from over 200 private solar energy companies to power Sri Lanka, is a very encouraging sign.

As a result of the six-year HE-Link programme SAREP (South Asia Renewable Energy Programme), the Solar Asia Conference series and the “Solar Village” project evolved. Solar Asia Conferences have taken place twice in Sri Lanka, once in Malaysia and once in India.

A pilot solar village started in 2008, and nine solar villages have been established in the country since. The concept of solar village is to empower rural communities by introducing a regular wealth creation method using solar energy and guiding them to develop themselves sustainably. This, in turn, contributes to reducing poverty and mitigating damaging climate change, benefits 80% of the Sri Lankan population who live in villages, and paves the way for the prosperity of Sri Lanka. To attract external funding and rapidly replicate solar villages in Sri Lanka, a “Solar Village SDG” community interest company (CIC) was formed in November 2024.

According to the latest SLSEA statistics, Sri Lanka has 2000 MW of solar and 200 MW of wind installations. This is 2.2 GW and a good fraction of the total power production capacity (~5 GW) in the country.

The intermittent nature of solar and wind can currently be balanced using hydropower until the fast-developing green hydrogen technology is established in Sri Lanka. When solar power is at its maximum power production during the daytime, the hydropower can be reduced simply by controlling the flow of water without any technical difficulties. With the positive steps taken by the GOSL and the private sector, Sri Lanka could become a renewable energy island in the future, giving the country many health and economic benefits and attracting many tourists from around the globe.

To achieve this noble goal, every sector in the country should work together. The general public should understand the benefits of using renewables and install more systems in the country, perhaps via “Crowd Funding”.

It is now clear that ROI (Return on Investment) from a solar roof is greater than the interest earned by keeping the money in the bank. PV companies must improve their “after-sale service” to increase customer satisfaction and help their customers get the most from their investment by promptly rectifying any issues arising from these new technologies.

The CEB has a great responsibility to gradually improve the national grid by reducing energy leakages and replacing weak transformers and grid lines to move towards a smart grid, enabling the absorption of more indigenous solar and wind energy.

Thoughts for Unduvap Poya

Published

on

Arrival of Arahant Bhikkuni Sangamitta

Unduvap Poya, which falls today, has great historical significance for Sri Lanka, as several important events occurred on that day but before looking into these, as the occasion demands, our first thought should be about impermanence. One of the cornerstones of Buddha’s teachings is impermanence and there is no better time to ponder over it than now, as the unfolding events of the unprecedented natural disaster exemplify it. Who would have imagined, even a few days ago, the scenes of total devastation we are witnessing now; vast swathes of the country under floodwaters due to torrential rain, multitudes of earth slips burying alive entire families with their hard-built properties and closing multiple trunk roads bringing the country to a virtual standstill. The best of human kindness is also amply demonstrated as many risk their own lives to help those in distress.

In the struggle of life, we are attached and accumulate many things, wanted and unwanted, including wealth overlooking the fact that all this could disappear in a flash, as happened to an unfortunate few during this calamitous time. Even the survivors, though they are happy that they survived, are left with anxiety, apprehension, and sorrow, all of which is due to attachment. We are attached to things because we fail to realise the importance of impermanence. If we do, we would be less attached and less affected. Realisation of the impermanent nature of everything is the first step towards ultimate detachment.

It was on a day like this that Arahant Bhikkhuni Sanghamitta arrived in Lanka Deepa bringing with her a sapling of the Sri Maha Bodhi tree under which Prince Siddhartha attained Enlightenment. She was sent by her father Emperor Ashoka, at the request of Arahant Mahinda who had arrived earlier and established Buddhism formally under the royal patronage of King Devanampiyatissa. With the very successful establishment of Bhikkhu Sasana, as there was a strong clamour for the establishment of Bhikkhuni Sasana as well, Arahant Mahinda requested his father to send his sister which was agreed to by Emperor Ashoka, though reluctantly as he would be losing two of his children. In fact, both served Lanka Deepa till their death, never returning to the country of their birth. Though Arahant Sanghamitta’s main mission was otherwise, her bringing a sapling of the Bo tree has left an indelible imprint in the annals of our history.

According to chronicles, King Devanampiyatissa planted the Bo sapling in Mahamevnawa Park in Anuradhapura in 288 BCE, which continues to thrive, making it the oldest living human planted tree in the world with a known planting date. It is a treasure that needs to be respected and protected at all costs. However, not so long ago it was nearly destroyed by the idiocy of worshippers who poured milk on the roots. Devotion clouding reality, they overlooked the fact that a tree needs water, not milk!

A monk developed a new practice of Bodhi Puja, which even today attracts droves of devotees and has become a ritual. This would have been the last thing the Buddha wanted! He expressed gratitude by gazing at the tree, which gave him shelter during the most crucial of times, for a week but did not want his followers to go around worshipping similar trees growing all over. Instead of following the path the Buddha laid for us, we seem keen on inventing new rituals to indulge in!

Arahant Sanghamitta achieved her prime objective by establishing the Bhikkhuni Sasana which thrived for nearly 1200 years till it fell into decline with the fall of the Anuradhapura kingdom. Unfortunately, during the Polonnaruwa period that followed the influence of Hinduism over Buddhism increased and some of the Buddhist values like equality of sexes and anti-casteism were lost. Subsequently, even the Bhikkhu Sasana went into decline. Higher ordination for Bhikkhus was re-established in 1753 CE with the visit of Upali Maha Thera from Siam which formed the basis of Siam Maha Nikaya. Upali Maha Thero is also credited with reorganising Kandy Esala Perahera to be the annual Procession of the Temple of Tooth, which was previously centred around the worship of deities, by getting a royal decree: “Henceforth Gods and men are to follow the Buddha”

In 1764 CE, Siyam Nikaya imposed a ‘Govigama and Radala’ exclusivity, disregarding a fundamental tenet of the Buddha, apparently in response to an order from the King! Fortunately, Buddhism was saved from the idiocy of Siyam Nikaya by the formation of Amarapura Nikaya in 1800 CE and Ramanna Nikaya in 1864 CE, higher ordination for both obtained from Burma. None of these Niakya’s showed any interest in the re-establishment of Bhikkhuni Sasana which was left to a band of interested and determined ladies.

My thoughts and admiration, on the day Bhikkhuni Sasana was originally established, go to these pioneers whose determination knew no bounds. They overcame enormous difficulties and obtained higher ordination from South Korea initially. Fortunately, Ven. Inamaluwe Sri Sumangala Thero, Maha Nayaka of Rangiri Dambulla Chapter of Siyam Maha Nikaya started offering higher ordination to Bhikkhunis in 1998 but state recognition became a sore point. When Venerable Welimada Dhammadinna Bhikkhuni was denied official recognition as a Bhikkhuni on her national identity card she filed action, with the support of Ven. Inamaluwe Sri Sumangala Thero. In a landmark majority judgement delivered on 16 June, the Supreme Court ruled that the fundamental rights of Ven. Dhammadinna were breached and also Bhikkhuni Sasana was re-established in Sri Lanka. As this judgement did not receive wide publicity, I wrote a piece titled “Buddhism, Bhikkhus and Bhikkhunis” (The Island, 10 July 2025) and my wish for this Unduvap Poya is what I stated therein:

“The landmark legal battle won by Bhikkhunis is a victory for common sense more than anything else. I hope it will help Bhikkhuni Sasana flourish in Sri Lanka. The number of devotees inviting Bhikkhunis to religious functions is increasing. May Bhikkhunis receive the recognition they richly deserve.” May there be a rapid return to normalcy from the current tragic situation.”

Royal Over Eighties

Published

on

Royal College

The gathering was actually of ‘Over Seventies’ but those of my generation present were mostly of the late eighties.

Even of them I shall mention only those whom I know at least by name. But, first, to those few of my years and older with whom speech was possible.

First among them, in more sense than one, was Nihal Seneviratne, at ninety-one probably the oldest present. There is no truth to the story that his state of crisp well-being is attributable to the consumption of gul-bunis in his school days. It is traceable rather to a life well lived. His practice of regular walks around the house and along the lane on which he lives may have contributed to his erect posture. As also to the total absence of a walking stick, a helper, or any other form of assistance as he walked into the Janaki hotel where this gathering took place.

Referencing the published accounts of his several decades-long service in Parliament as head of its administration, it would be moot to recall that his close friend and fellow lawyer, J E D Gooneratne, teased him in the following terms: “You will be a bloody clerk all your life”. He did join service as Second Assistant to the Clerk to the House and moved up, but the Clerk became the Secretary General. Regardless of such matters of nomenclature, it could be said that Nihal Seneviratne ran the show.

Others present included Dr. Ranjith de Silva, Surgeon, who was our cricket Captain and, to the best of my knowledge, has the distinction of never engaging in private practice.

The range of Dr. K L (Lochana) Gunaratne’s interests and his accomplishments within each are indeed remarkable. I would think that somebody who’d received his initial training at the AA School of Architecture in London would continue to have architecture as the foundation of his likes /dislikes. Such would also provide a road map to other pursuits whether immediately related to that field or not. That is evident in the leadership roles he has played in the National Academy of Sciences and the Institute of Town Planners among others. As I recall he has also addressed issues related to the Panadura Vadaya.

My memories of D L Seneviratne at school were associated with tennis. As happens, D L had launched his gift for writing over three decades ago with a history of tennis in Sri Lanka (1991). That is a game with which my acquaintance is limited to sending a couple of serves past his ear (not ‘tossing the ball across’ as he asked me to) while Jothilingam, long much missed, waited for his team mates to come for practices. It is a game at which my father spent much time both at the Railway sports club and at our home-town club. (By some kind of chance, I recovered just a week ago the ‘Fred de Saram Challenge Cup’ which, on his winning the Singles for the third time, Koo de Saram came over to the Kandana Club to hand over to him for keeps. They played an exhibition match which father won). D L would know whether or not, as I have heard, in an exhibition match in Colombo, Koo defeated Frank Sedgman, who was on his triumphant return home to Oz after he had won the Wimbledon tournament in London.

I had no idea that D L has written any books till my son brought home the one on the early history of Royal under Marsh and Boake, (both long-bearded young men in their twenties).

It includes a rich assortment of photographs of great value to those who are interested in the history of the Anglican segment of Christian missionary activity here in the context of its contribution to secondary school education. Among them is one of the school as it appeared on moving to Thurstan road from Mutwal. It has been extracted from the History of Royal, 1931,  done by students (among whom a relative, Palitha Weeraman, had played a significant role).

As D L shows, (in contra-distinction to the Catholic schools) the CMS had engaged in a largely secular practice. Royal remained so through our time – when one could walk into the examination room and answer questions framed to test one’s knowledge of Christianity, Buddhism, Hinduism and Islam; a knowledge derived mostly from the lectures delivered by an Old Boy at general assembly on Friday plus readings from the Dhammapada, the Bhagavad Gita, the St. John’s version of the Bible or the Koran recited by a student at senior assembly on Tuesday / Thursday.

 D L’s history of Royal College had followed in 2006.

His writing is so rich in detail, so precise in formulation, that I would consider this brief note a simple prompt towards a publisher bringing out new editions at different levels of cost.

It was also a pleasure to meet Senaka Amarasinghe, as yet flaunting his Emperor profile, and among the principal organisers of this event.

The encounter with I S de Silva, distinguished attorney, who was on Galle road close to Janaki lane, where I lived then was indeed welcome. As was that with Upali Mendis, who carried out cataract surgery on my mother oh so long ago when he was head of the Eye Hospital. His older brother, L P, was probably the most gifted student in chemistry in our time.

Most serendipitous perhaps was meeting a son of one of our most popular teachers from the 1950s, – Connor Rajaratnam. His cons were a caution.

“Regulatory Impact Assessment – Not a bureaucratic formality but essentially an advocacy tool for smarter governance”: A response

Published

on

Having meticulously read and re-read the above article published in the opinion page of The Island on the 27 Nov, I hasten to make a critical review on the far-reaching proposal made by the co-authors, namely Professor Theekshana Suraweera, Chairman of the Sri Lanka Standards Institution and Dr. Prabath.C.Abeysiriwardana, Director of Ministry of Science and Technology

The aforesaid article provides a timely and compelling critique of Sri Lanka’s long-standing gaps in evidence-based policymaking and argues persuasively for the institutional adoption of Regulatory Impact Assessment (RIA). In a context where policy missteps have led to severe economic and social consequences, the article functions as an essential wake-up call—highlighting RIA not as a bureaucratic formality but as a foundational tool for smarter governance.

One of the article’s strongest contributions is its clear explanation of how regulatory processes currently function in Sri Lanka: legislation is drafted with narrow legal scrutiny focused mainly on constitutional compliance, with little or no structured assessment of economic, social, cultural, or environmental impacts. The author strengthens this argument with well-chosen examples—the sudden ban on chemical fertilizer imports and the consequences of the 1956 Official Language Act—demonstrating how untested regulation can have far-reaching negative outcomes. These cases effectively illustrate the dangers of ad hoc policymaking and underscore the need for a formal review mechanism.

The article also succeeds in demystifying RIA by outlining its core steps—problem definition, option analysis, impact assessment, stakeholder consultation, and post-implementation review. This breakdown makes it clear that RIA is not merely a Western ideal but a practical, structured, and replicable process that could greatly improve policymaking in Sri Lanka. The references to international best practices (such as the role of OIRA in the United States) lend credibility and global context, showing that RIA is not experimental but an established standard in advanced governance systems.

However, the article could have further strengthened its critique by addressing the political economy of reform: the structural incentives, institutional resistance, and political culture that have historically obstructed such tools in Sri Lanka. While the challenges of data availability, quantification, and political pressure are briefly mentioned, a deeper analysis of why evidence-based policymaking has not taken root—and how to overcome these systemic barriers—would have offered greater practical value.

Another potential enhancement would be the inclusion of local micro-level examples where smaller-scale regulations backfired due to insufficient appraisal. This would help illustrate that the problem is not limited to headline-making policy failures but affects governance at every level.

Despite these minor limitations, the article is highly effective as an advocacy piece. It makes a strong case that RIA could transform Sri Lanka’s regulatory landscape by institutionalizing foresight, transparency, and accountability. Its emphasis on aligning RIA with ongoing national initiatives—particularly the strengthening of the National Quality Infrastructure—demonstrates both pragmatism and strategic vision.

At a time, when Chairmen of statutory bodies appointed by the NPP government play a passive voice, the candid opinion expressed by the CEO of SLSI on the necessity of a Regulatory Impact Assessment is an important and insightful contribution. It highlights a critical missing link in Sri Lanka’s policy environment and provides a clear call to action. If widely circulated and taken seriously by policymakers, academics, and civil society, it could indeed become the eye-opener needed to push Sri Lanka toward more rational, responsible, and future-ready governance.
