Power supply is generated by hydropower, wave power / wave energy, coal fired, nuclear, wind power and also solar from sunlight
The safest means is by solar power followed by wind power as they are environment friendly. Solar power is the conversion of energy from sunlight into electricity either directly using photovoltatics, indirectly using concentrated solar power which uses lenses or mirrors with tracking systems to focus on a large area of sunlight into a small beam. Made from efficient solar cells and conforming to international standards, performance and reliability are not compromised.
Advantages of using solar system are:
Solar power is a renewable resource
Non-polluting
Energy and heat from the sun is free
Solar cells require little maintenance
No moving parts to be replaced or maintained
Replacement after 20 years
Very versatile used in cars, water heaters, buildings, satellite, aviation, street lighting, remote telecommunications systems, highway emergency phones

3 Phase Solar : What You Need to Know about Connecting Solar to Your 3 Phase Supply
There is an awful lot of confusion (and misinformation) out there about the practicalities of installing solar on a house that has a 3 phase solar system supply. So Iâ??ve written this post to clear up the confusion.
Connecting solar power to a three phase solar system supply is entirely possible. But you need to decide how you are going to connect your solar system to the grid. Your 3 options are:
1) connect your solar system to only one of your supply phases with a single-phase solar inverter.
2) connect your system into all 3 phases of your supply with a single, 3-phase solar inverter
connect your system into all 3 phases with 3 separate single-phase inverters.
