Unfortunately, the process of converting it into electricity is very expensive. It will cost you about a million bob to replace your KPLC connection and enjoy the same appliances that you have in your house. It's like the free truck without tyres!!

They payback time is toooooo loooooong - something like 25yrs. You can only do it as a matter of principle; not economics. If you are worried about KPLC's reliability, then what you need is a good UPS - without the panels Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.

Now two companies have started the process of building large scale renewable energy generators in these regions. They haven't gone solar; they chose wind. WHY? It is much cheaper and more available than sunshine...even in the sunniest region of the country! Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.

The KVA does not determine the length of time the UPS will last. It tells you the size of load it can support. For a typical house, I think 3KVA would be enough. The parameter that determines the duration is the AH (ampere hour) rating of the battery. For 6 hours you will probably need a 500AH battery.

Rank: Elder Joined: 7/26/2007 Posts: 6,514		I installed a 300 litre solar water heater in my house 5 years ago. Cost me 120k back then (I hear prices have dropped). My power bill dropped by 45% in month one, and has remained the same within 10% of that through power price hikes and dips. I have recently added 2 instant showers as I have a large family and many guests. No effect on monthly bills. A friend built his home in 2007 and installed a full house solar system from Australia. Cost him 1M. His power bill is 200 bob monthly and his home is bigger than mine. Business opportunities are like buses,there's always another one coming
