How much does it cost to add solar power to add value to your home?
4.2 K system providing 70 to 85% of the annual average power
Not enough to justify the cost of installation, unless you can get some really fat subsidies. Solar system costs about $ 10 per watt of installed capacity, and a system can generate more than 2 kWh per installed watt of electricity annually, worth somewhere around 25 cents. I have a friend installed one, the list price was $ 13,000, but subsidies to reduce the net cost to $ 5.000. The system generates about $ 300 of electricity per year.
