Solar energy a clean renewable source with no emission and low recurring cost. In past recent years the technology of solar energy and its usage has experienced a phenomenal change and rapid growth. Promotional and encouraging government policies about solar energy, technological improvements in less setup and maintenance cost, growing public awareness in environmental issues, easy way to cutting down the users electricity bills with assured power supply 24x7 are some of the facts that have facilitated and sustained this strong interest in the minds of the users about solar technology worldwide including Sri Lanka. We all are facing the challenge of climate changes. According to World Bank report release in August 2016, Sri Lanka loses 7.7% of its income due to environment pollution specially from burning fossil fuels[5]. By setting up renewable environment friendly energy sources are aimed to prove countries contribution to global effort and support to reduce the climate challenges. Sri Lankan government’s budget proposals for the year 2018 has presented strategies for environmental friendly developments to the country based on the United Nations sustainable development goals. As a geographical advantageously located topical country close to equator, where sunlight remains 365 days per year, 8 to 10 hours a day, is a great intensity for generation of solar electricity. Therefore solar energy has a great potential as future energy source in Sri Lanka. Present consumption level of electricity is about 12,000 GWh, with an increase rate of 6.5% to 9% annually[2]. Ceylon Electricity Board had identified that Sri Lanka needs additional 4000GWh by end of 2025 [1]. This amount is planned to be generated through solar energy, other renewable and other indigenous energy resources. Sri Lankan government’s aim of electrification 100% of houses became a success. But without adequate supplies of affordable energy at reasonable generation cost, it is impossible to achieve the future targets. The project “Battle of Solar Power” is a progressive turn to convert customers rooftop into a solar power plant is one major economical green project. Sunlight is a free resource, the foreign exchange spend on fossil fuels will be remain in the country.
