Solar Panels FAQ
Solar panels receive sunlight and then convert it into DC current. The solar inverters then convert the DC current into AC current for your home to use. Your electrical box distributes power from the solar system to your appliances. If you have a solar battery, excess electricity not used by your home will be stored on it. Any excess electricity not used in your home or stored in a battery will be exported to the utility grid.
See our page on How Do House Solar Panels Work for more detailed information.
Modern solar panels have efficiency ratings of 15% to 22%. This means they can convert 15% to 22% of sunlight into usable energy. The factors involved in efficiency are:
- The quality and efficiency rating of the solar panels used;
- Orientation towards the sun, typically determined by which roof plane they are installed on; and
- Weather conditions in the area and climate.
Cleaning solar panels is a four step process:
- Use a soft brush to remove dust and other objects;
- Use a hose to wash the solar panels with water;
- For the areas the hose did not clean, scrub with a soft brush and water.
- Monitor your home’s solar output with your monitoring app to see if your cleaning increased production.
