solar cost per kwh 2015
So what is the current cost of residential solar power? As of early 2015, itâs approximately $3.00 per installed watt. The average sized solar panel system is 5,000 watts, so this brings the total cost to $15,000. That 15k figure is just an average amount.he typical solar installer does not make the price of solar easy to find online. This is unfortunate, as more homeowners would switch to solar power if they knew how much they could save over the long term. The average homeowner would save at least $25,000 over 25 years by switching to solar.
