Considerations for Residential Rooftop Solar Panel Installation

· Industry News

Residential rooftop solar power is taking the world by storm with its energy-saving, green features. More and more villa owners are also using distributed PV as a standard part of their renovation. What do you need to pay attention to in the process of installing distributed PV?

1. Is the residential roof suitable for solar installation?

As distributed PV needs to be installed on the roof, there are requirements for the conditions of the roof.

Firstly, one needs to have a roof of their own. Having a roof on your own home is the best condition.

Secondly, the size and orientation of the roof will directly contribute to the amount of electricity generated. Large, south-facing roofs are definitely a favourite for distributed PV. Not only can you maximise the installation of solar panels, but you can also maximise the efficiency of your electricity production. However, in reality such roofs are in the minority. The vast majority of roofs have problems such as small roof areas and north-facing orientation. While this is a significant obstacle to the installation of distributed PV, the efficiency of the roof can be maximised through professional scheduling and design.

Finally, the presence or absence of obstructions near the roof also directly affects the efficiency of distributed PV generation. Around the roof, there may be utility poles, satellite pots, trees and other obstructions. The avoidable ones, such as trees, can be solved by appropriate trimming. However, for unavoidable factors such as utility poles, the extent of shading influence can only be calculated through shading analysis. This can be used as a reference basis in the subsequent layout to design the most powerful layout design.

2. Choose a professional PV power system service provider

With a suitable roof, it is necessary to choose a professional PV power generation system service provider.

The installation of distributed photovoltaic requires professional skills, the construction personnel must come from a plumbing background, understand the structure, understand the drawings, understand the electrical, but also familiar with the use of various tools, as well as the characteristics of the photovoltaic system itself. As the PV system is designed to last 25 years, the system is required to be as safe and stable as possible, and the auxiliary materials and hardware to achieve a very long life. The roof also needs to be fixed by breaking holes at a certain point and be well waterproofed, even with multiple waterproofing processes.
