How can I make my solar cell cheaper?

One way to reduce the cost of solar is to improve the efficiency of the solar panels. With a higher efficiency, fewer panels, or modules, need to be installed to reach a desired power target. This means less labor, less land and less hardware.

How can we make solar cells more efficient?

Solution: On hotter days, less energy is needed to excite the electrons so less energy is transferred from the sun to the solar cells. In short, cooler, sunny weather makes for the most effective solar panel efficiency.
