1、Which roofs are suitable for installing photovoltaic power stations?

The roof of a rural villa, if in good condition and unobstructed, is undoubtedly an ideal choice for installing household photovoltaics. Residents preparing to install photovoltaics can check if there are any obstacles around their roofs and confirm if the lighting conditions are sufficient. Usually, flat roofs and sloping roofs are more suitable for the installation of photovoltaic power plants.

2、The advantages of a flat roof: affordable and efficient power generation

Flat roofs provide ideal conditions for the installation of photovoltaic power plants. On such roofs, photovoltaic arrays can be arranged at the optimal angle to ensure maximum power generation efficiency. In addition, installing photovoltaic power plants on flat roofs also has significant insulation and cooling effects, generally reducing the temperature of the roof by 5 to 7 degrees. By using cement piers combined with photovoltaic brackets for installation, not only is the investment cost cost-effective, but it can also bring considerable economic benefits to residents.

3、Sloping roof: combining aesthetics and practicality, easy to install

The installation of photovoltaic power stations on sloping roofs not only has a beautiful and elegant appearance, but also, due to the large slope of the roof, allows rainwater to be quickly drained, reducing maintenance needs. In addition, the construction process of this type of roof is relatively simple and easy to maintain. When installing a photovoltaic power station, there is no need to raise the bracket or calculate the inclination angle, just lay it according to the natural inclination angle of the roof. At the same time, the area utilization rate of sloping roofs is also high, not limited by area, and their large slope can also serve as an automatic cleaning tool for power plants.

4、Conditions and limitations for installing photovoltaic power plants

The primary condition for installing a photovoltaic power station is to ensure clear ownership of the roof. Due to the need for independent usage rights for household photovoltaic power plants, it is more convenient for residents of villas with independent roofs to install them in rural areas. However, for the rooftops of multi story or high-rise residential buildings, these areas are public areas and not individual households, and their usage rights are jointly owned by the owners of the entire building. If you want to build photovoltaic power stations in these areas, you must obtain the joint consent of all owners.

5、The installed capacity and investment cost of photovoltaic power plants

In terms of installed capacity, it mainly depends on the roof area. Generally speaking, household roofs can be equipped with 3kW to 10kW household photovoltaic projects. If the roof area is larger or higher power components are used, even larger photovoltaic power plants can be built. Usually, a roof of about 10 square meters can accommodate 1kW of photovoltaic equipment. By adjusting the array and actual layout reasonably, and selecting high-power components, an area of 7-8 square meters can also achieve kilowatt level installed capacity.
