is residentil solar worth the cost?
<answer> No <context> To determine the cost of residential solar panels, begin by looking at your last electric bill. You need to determine how many kilowatt hours you use on average. This is listed on your bill, as well as the kilowatt hours that you used in the past few months. Then, choose a solar panel system that matches your needs.nce these were factored in, the actual cost of the system was around $6,000 plus the cost of installation. The current federal tax credit is 30 percent of the cost of home solar panels. You will receive that back as a refund on your next year’s taxes.
