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 tocalculate the resource for a flat plate collector tilted to latitude, rather than

Benefits of Solar Cell


37/53

Benefits of Solar CellEner a Zero Emission

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 therecostly electricity bills.

Combined with energy efficiency and energy saving and use of LED lamps the nightpeak 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 Pollutionand Global warming.

It is expected that bilateral and multilateral finance and market stimulationprograms based on best service at least cost will be soon available

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 ofenergy

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, ithelps 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 inthe 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
