When the sun’s rays hit the solar panels on your roof, it is turned into DC current electricity. The problem is that your home uses AC current electricity, which is why you need to install an inverter. The inverter converts the DC current to AC current, which can then be used in your home with the excess fed into the grid (or stored in your battery, if you have one).

Solar panels will stop generating electricity at night but will still generate electricity on cloudy or rainy days, just not as much as on sunny days. To create electricity, your solar panels need direct sunlight, so whilst it doesn’t need to be a bright sunny day all the time, the more sun that hits your panels, the more electricity is produced.

This depends on a number of factors that include how much electricity your system produces, its efficiency, how much electricity you use, where you live, and the rate you are charged by your electricity provider.

Most quality solar panels are designed to be self cleaning in the rain. If you don’t have much rain for a period of time however, they can collect dust, debris and bird droppings that will reduce the amount of electricity produced. So it’s a good idea to regularly check your panels and clean them with a hose or cloth, as necessary.

Yes, installing solar panels on your roof will generally increase the value of your property. Many buyers look for properties that already have solar power installed, because they can pay lower electricity bills immediately without installing the panels themselves.

Solar panels help the environment because solar power is a renewable resource. Solar power lets you use the sun to power your home, which is a renewable, sustainable and environmentally friendly form of energy.
