These panels are mounted on the owner's roof and plugged into a power supply that draws minimal energy. The cells on the panels capture the sun's energy and transfer it throughout your home. Photovoltaic roof panels do not evenrequire direct sunlight to be effective, as they can capture energy even on a cloudy day.
Photovoltaic roof panels are made up of layers of semi-conducting material, such as silicon thin film. When sunlight hits these cells, it creates an electric across the layers. The panel itself is made up of multiple cells. Like a standard light bulb, the power of these cells is measure in kilowatts. This is the rate the solar panels generate their energy when operating at peak performance.
Benefits of photovoltaic roof panels
There are many benefits of photovoltaic roof panels. The obvious benefit is that you will save substantially on your energy bill, as sunlight is free. Not only that, but you can sell surplus energy produced by the panels back to the power grid via the UK's feed-in tariffs plan. In optimum conditions, surplus energy can net you as much as 1200 pounds per year. Photovoltaic roof panels also greatly reduce your carbon footprint, because solar electricity is green. This kind of renewable energy doesn't release harmful pollutants, such as carbon dioxide, into the atmosphere. Think about it this way: if you have photovoltaic roof panels in your home, you could save over a ton of C02 gas per year. Photovoltaic roof panels also come in many shapes and sizes, so you can easily find a model that can be installed atop your particular roof.
