Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect. The solar panels consist of multiple photovoltaic (PV) cells made of semiconductor materials. When sunlight strikes these cells, it excites electrons, creating an electric current. This current is then captured and converted into usable electricity.

Solar panels can generate electricity even in cloudy or overcast conditions. While direct sunlight produces the maximum power output, solar panels can still function and produce electricity under diffused light. However, the amount of electricity generated may vary depending on the intensity of sunlight and the specific panel efficiency.

Solar panels produce electricity during the day when sunlight is available. Excess electricity generated during the day can be stored in batteries for use during low sunlight periods or at night. Alternatively, when your solar system is connected to the grid, you can draw electricity from the grid during these times, and your excess solar energy can be fed back into the grid, earning you credits or compensation.

Solar power has the potential to significantly reduce or even eliminate your electricity bills, depending on various factors such as your energy consumption, system size, and available sunlight. By generating your electricity, you reduce your reliance on the grid and the amount of electricity you need to purchase. With a well-designed solar system, you can save a substantial amount on your energy bills over its lifespan.
