The price of solar is usually measured in dollars per watt. The price depends on a variety of factors, including your roof type, the size of the array, and the orientation of the panels.
The best way to understand the true cost of solar is by comparing it to the cost of energy from the utility. With a financed solar array, your monthly payment should always be equal or lower than the monthly bill you were paying to the utility. With a cash purchase, you should see a payback time of more or less 7 years. Learn more about this cost comparison on the blog.
A final cost to consider is the environmental cost of solar compared to grid energy. In a previous FAQ we explain that solar in Florida can reduce your carbon footprint by 11,000 pounds per year, which is a significant environmental cost reduction compared to energy from the utility.
