Solar energy system is a popular new way of generating electricity. With the shortage of coal resources, the use of new energy to replace old energy has become our new demand. Many areas have begun to install solar power system. So what are the conditions for the roof to be suitable for installing solar energy system?
1. There is an independent roof or the roof has a clear property right.
2. The roof has enough light. The power station is generally installed on the south-facing roof, so as to better ensure sufficient light every day. In addition, external obstacles such as trees, telephone poles, parapets, etc. will also affect the sunlight. These factors need to be taken into account.
3. The roof has enough area. The roof area is a relatively intuitive factor. A rough estimate is that the installation area of the 3KW system is about 22~35㎡, the 4KW system is about 30~50㎡, and the 5KW system is about 45~60㎡.
4. The roof has sufficient load-bearing capacity. The roof load-bearing problem must be considered in the early stage of the design of photovoltaic power plants.
