Effective use of idle roofs, under the premise of meeting their own electricity needs, can also sell unused electricity to the State Grid, which not only saves electricity bills, but also increases revenue.Whether it is to supply our own electricity or as an investment, what factors do we need to consider when building a Solar panel mount power station?

1.Is your roof big enough?

Taking a 5KW photovoltaic power station as an example, the number of photovoltaic modules is about 16, and the usable roof area is required to be greater than about 35 square meters. If it is insufficient, it cannot be installed.

2.Is the orientation of your roof suitable for installing photovoltaic power plants?

In China,it is best to install Solar mounting system power plants in the south. In the northern hemisphere for example, when the power generation panels face south, the power generation is the highest, and the solar radiation is also the best. Especially in summer, after noon is the time when the solar radiation is strongest. When the direction is due south to west, the maximum power generation will be obtained; similarly, the maximum solar radiation direction in winter is slightly east. Therefore, as long as your roof is within ±10° of the south, it will not have much impact on power generation.

3.Are there any obstructions around your roof?

The surrounding environment of the house is very important. Shadow occlusion has an extremely important impact on solar panel roof mounts power generation systems, and the life of photovoltaic modules is also closely related to this. Therefore, obstacles should be avoided as much as possible in the area where the system is installed.Not all roofs facing south can be installed with photovoltaic modules. We have to consider that the surrounding trees and other buildings will not block the photovoltaic modules. Obstacles will cause a hot spot effect on solar panels, which will not only affect the overall power generation, but also cause fatal damage to the panels.

4.Is your roof strong?

The solar roof racking is built on the roof. It is necessary to fully consider the fixed load, wind load, snow load, and seismic load capacity of the roof. At the same time, it must have enough capacity to carry the weight of photovoltaic modules, brackets and photovoltaic cables.

The feature of photovoltaic power generation is stable income, with a return rate of about 10%, but it requires regular income for up to 25 years. A stable cash flow every month or quarter still has good economic benefits.

If the above conditions are met, take action as soon as possible and install a photovoltaic power generation system on the roof.
