  21. 21. The annual results for Sri Lanka, which range from 4.5 to 6.0 kWh/m2/day, are consistent with, and slightly higher than earlier studies using sunshine recorders, which gave results of 4.2 to 5.6 kWh/m2/day. The slightly higher results are due most likely to the fact that, for Sri Lanka, we chose to calculate the resource for a flat plate collector tilted to latitude, rather than the more traditional method of calculating the resource on a horizontal surface that the earlier studies used. With two axis tracking one axis done manually for seasons we can get 7.32 kWh/m2/day. http://www.nrel.gov/docs/fy03osti/34645.pdf http://rredc.nrel.gov/solar/codes_algs/PVWATTS/version1/#map With a 4kW system we can get this amount of Energy • Radiation Energy Energy • (kWh/m 2/day) (kWh) Axis tracking per Watt/day • Colombo Ratmalana • 6.58 7411 2 1.85 22.5% Extra • 6.35 7172 1 1.79 • 5.38 6028 0 1.51 • Colombo/Katunayake • 6.71 7632 2 23.56% Extra • 6.47 7377 1 • 5.46 6177 0 • Hambantota • 7.32 8494 2 2.12 29% Extra • 7.00 8140 1 • 5.71 6583 0 • Trincomalee (AFB) • 7.11 8033 2 26.1% Extra • 6.83 7731 1 • 5.64 6343 0

Simple Payback period < 4 Years Cost per kWh amortized with batteries = $0.25 Money saving for consumers >331kWh/M = Rs1,252,693/Y (At today’s tariff of Rs32.50 for>180 units Net metering but surely the CEB tariff will increase ) Typical CO2 emission from oil 583 kg/MWh Emissions saved (kg) 22,148 Typical fuel consumption per MWh 125 gal. Fuel saved (gal) 4,749. Cost of fuel saved for the country Rs 1,258,336. Assuming all marginal units are from Diesel Fuel Saving in Import Rs719,049/house (At today's import price but which will soon go up )

  28. 28. The SolarWall® PV/thermal solar system is housed on the roof of a service centre and health clinic for the Olympic athletes in Beijing PV module efficiency is typically between 8-20%. What happens to the rest of the sun’s energy that shines on the panels? Most of it is converted into heat energy, which normally is lost and provides no value to the system owner. As well, the heat build-up behind PV modules reduces the electrical output by 0.4-0.5% for every 1°C above its rated output temperature (which is 25°C). Given that roofs can reach temperatures as high as 90°C, the actual operating efficiency of PV systems is often significantly less than the rated output.
  29. 29. Benefits of Solar Cell Energy a Zero Emission Technology • More manual labor jobs will be created • The value of the property will go up • By distributed generation day peak will come down. Transmission and Distribution losses will be reduced. • Reduction of costly oil imports to the country • Reduction of costly Gas turbine generation and costly Private power. • Reduction of Global warming • Reduction of polluting CO2 and other CHS Gasses • Reduction of wasteful use of water in thermal Power stations • With net metering the large homes will benefit more on reducing there costly electricity bills. • Combined with energy efficiency and energy saving and use of LED lamps the night peak can also be reduced to benefit the utility. • Should be able to get Renewable Energy Certificates and Carbon trading • Low interest soft loans will become available from the local banks like for Rural solar home systems • A mental satisfaction that we have not contributed to Pollution and Global warming. • It is expected that bilateral and multilateral finance and market stimulation programs based on best service at least cost will be soon available Distributed Generation: the Next Step in Smart Power Distribution Solar Power is commercially viable.

  34. 34. Solar power has several advantages • Economical Benefits: • The energy from the sun is practically free, after the initial investment has been recovered • Solar energy reduces our dependence on foreign or centralized conventional source of energy • Solar energy supports local jobs and creates wealth, which elevates local economies • Environmentally Friendly: • Solar energy is clean, quiet, renewable and sustainable unlike other conventional energy sources such as gas, oil, and coal • Solar energy does not contribute to global warming, acid rain, or smog, on the contrary, it helps to lower harmful green house gas emissions • • Independent/Semi-Independent: • Solar energy reduces our dependence on foreign or centralized sources of energy • Solar energy can reduce your electric bill, and also supply your property with electricity in the event of a power outage • Solar energy systems can operate entirely independent from a power or gas grid; therefore systems can be installed in remote location • • Low or no Maintenance: • Solar energy systems are virtually maintenance free and will last at least 25 years • System sizes can be increased in the future as your electricity needs grow • Systems operate silently, and have no moving parts
