It usually costs 15 000 to 20 000 after tax credits and can reduce your electricity bill by 70 to 100 percent depending on the size and. On average installation and the system together can run between 15 000 and 25 000.

Buying your solar electric system outright is best. One 150 to 300 watt solar panel costs 112 to 450 on average or between 0 75 to 1 50 per watt depending on the type of panel energy efficiency rating and size. Although solar panels do get cheaper on a per watt basis as the system size gets bigger the overall cost of the system increases as well. However if a homeowner is trying to buy one or two panels on their own for a small diy project they will likely pay closer to 1 per watt.

Therefore if the solar panel output is 250 watts that single panel might cost you 187 50. Solar companies can typically get a single solar panel at a price of 0 75 per watt. Solar companies that purchase in bulk typically spend 0 75 per watt whereas homeowners spend 1 per watt.
