Most countries encourage residents to install home PV plants, through tax incentives and policy subsidies. The ultimate vision is similar, allowing society to achieve carbon neutrality and green energy-saving sustainable development. Specifically for individuals, how should ordinary families install photovoltaic panels on their own roofs? What conditions are required? What are the differences between the different types of roof installation methods? This article will answer all of your questions.
Is my roof suitable for installing a PV solar system?
First of all, you have to observe whether there are shadows around your own roof and whether the light conditions are good. And a country house is most suitable for installing a rooftop PV system - sunny and unshaded.There are many kinds of construction materials for roofs, so we won't discuss them for now. Here we divide roofs into flat and pitched roofs.
Flat roofs.
Flat roof PV systems are generally installed in the form of concrete columns and PV brackets. The investment cost is not high and the economy is better.On a horizontal roof, we can determine the angle of the PV panels by adjusting the brackets so that the PV system receives the most light radiation to obtain the maximum power generation.The biggest benefit of installing PV power plant on a flat roof is heat insulation and temperature reduction, which can generally reduce the temperature by 5~7 degrees.
Pitched roofs.
With a sloped roof of PV power plant, rainwater is automatically discharged due to the slope of the roof, no water will accumulate, and the PV panels can also be cleaned automatically.Pitched roofs do not need to increase the height of the bracket or calculate the angle of tilt, and are easier to erect and maintain.However, pitched roofs are usually tiled, and special attention needs to be paid to the protection of tiles and roof waterproofing when installing PV panels.
