How much does it cost to install solar photovoltaic panels at home? You need to understand these knowledge.

Nowadays, many families choose to install solar photovoltaic energy storage and power generation systems on their own roofs. Let's analyze how much it costs to install rooftop solar energy storage and power generation.

Features: The conversion efficiency is slightly higher than that of multi-crystalline silicon with the same area, and the cost is naturally higher than that of multi-crystalline silicon photovoltaic components, and the service life is basically the same as that of multi-crystalline silicon photovoltaic components.

There are three kinds of roofs for installing photovoltaic power generation: color steel roof, brick and tile structure roof and flat concrete roof. Different roofs have different installation methods of photovoltaic power stations and different installation areas.

When installing photovoltaic power stations on steel structure color steel tile roofs, usually only install photovoltaic components on the south side, the laying ratio is 10 square meters per kilowatt, that is, 10,000 square meters are needed for 1 megawatt (1 megawatt = 1000 kilowatts) project.

When installing photovoltaic power stations on brick and tile structure roofs, usually the photovoltaic components will be fully laid in the roof area without shading from 8:00 to 16:00, although the installation method is different from that of color steel roof, the laying ratio is similar, which is about 10 square meters per kilowatt.

When installing photovoltaic power systems on flat roofs, in order to make the components receive as much sunlight as possible, a horizontal inclination angle needs to be designed, so a certain interval is needed between each row of components to avoid being shadowed by the front row of components. Therefore, the roof area occupied by the whole project will be greater than that of color steel tile roofs and villa roofs that can realize flat laying of components.

In general, the cost of installing photovoltaic power projects will vary according to the installation environment and installation methods. To determine the budget for installing photovoltaic power systems, you need to understand the installation environment, photovoltaic component specifications, installation methods, installation area, quotes, etc., these knowledge can help you better understand and calculate the cost of photovoltaic power projects.
