Do Solar Panels Work on a Cloudy Day?

Written by Interconnection Systems, Inc., Central City, Nebraska

Solar panels require sunlight to generate electricity for your home so they do not work in darkness. Thus they will not produce at night, but what about on a cloudy day? The purpose of a solar panel system is to absorb sunlight, also known as photovoltaic (PV) energy, and convert it to direct current (DC) power. This DC power is then sent through the solar array’s inverter to be converted to alternating current (AC) power, which is the type of power households run on. At that point, your solar array can feed electricity into your home and out onto the electric grid.

If the homeowner has a solar array equipped with a battery system, they may use power directly from their solar array. Otherwise, all energy is sent to the grid and measured by a bidirectional meter. This allows the power utility to credit the customer’s account, reducing their energy bill. Click here to download the article.
