Switching to solar is advisable considering the current global warming-climate change scenario and air pollution caused by Thermal power plants. Installation of 100 KWp of Solar power system, saves about 110 tonnes of Carbon-di-oxide gas emission and equals to carbon absorption done by approximately 4,000 trees.
Minimum Operating & Maintenance:
The solar power system has no running parts like generator and so has minimum operating and maintenance cost. Also, unlike generator, system does not produce any noise or vibrations.
The solar-panels used for producing electricity has service life of 25 years.
Medium term payback period:
Investment on solar power plant payback its cost in period 4-5 years, through savings in electrical bills, after which, the client has next to free electricity supply for next 15-20 years. A 6 KW capacity of solar rooftop generates close to 8,000-10,000 units annually.
Protection from future rise in electricity costs:
The grid power costs increases at an average rate of 2-5% per annum. Switching to solar also guarantees protection against any such rise in electricity tariff.
