Energy Efficient Homes Solar Panels

Solar panel efficiency is a measure of the amount of solar energy irradiation which falls on a panel surface and is converted into electricity.

Energy efficient homes solar panels.

Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts with higher power ratings generally considered preferable to lower power ratings. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity.
