Solar energy uses the sun’s energy to produce electricity. Photovoltaic (PV) cells used in solar panels are the first step. These cells have layers of silicon-based semiconducting material that, when exposed to sunlight, produce an electric field.

When sunlight hits the solar panels, the PV cells absorb the energy and convert it into direct current (DC) electricity. This DC electricity is then converted into alternating current (AC) electricity through an inverter. AC electricity is the type of electricity used in most homes and businesses.

Yes, solar panels can still generate electricity on rainy or cloudy days, although their efficiency may be reduced. While direct sunlight produces the most electricity, solar panels can still capture diffuse sunlight and convert it into usable energy. Even on overcast days, solar panels can generate a significant amount of power, helping you save on your energy bills.

On average, homeowners in Canada can save over $20,000 in energy costs over the lifespan of their solar panels. These savings are achieved by reducing or eliminating your reliance on traditional electricity sources, which are subject to rising utility rates.

Solar panels are designed to be low-maintenance, but they do require occasional cleaning to ensure optimal performance. Dirt, dust, leaves, and other debris can accumulate on the surface of the panels and hinder their ability to capture sunlight effectively.

Fortunately, most solar panels are self-cleaning to some extent. Rainfall can help remove some dirt and debris, but it may not be sufficient in all cases. If you notice a significant build-up of dirt or if you live in an area with less rain, it’s advisable to clean your solar panels periodically. Use a soft brush or sponge, along with mild soapy water, to gently clean the surface. Avoid using abrasive materials or high-pressure washers, as they can damage the panels.
