The Installation of Photovoltaic Power Generation Systems Should Be Tailored to Local Conditions.

“Hello, how much investment is needed for the installation of a grid-connected power generation system?” This is often what we hear from customers. As a practitioner in the solar photovoltaic power generation industry, it is essential to possess professional knowledge to provide feasible solutions to such general inquiries.

A home solar power generation system can be installed if you are in an independent unit or villa with adequate rooftop resources. Then, the next question arises: what is the installed capacity of the roof? How much electricity can be generated daily?

Home solar power generation systems commonly utilize crystalline silicon photovoltaic solar panels. These panels are connected in various series and parallel configurations. During installation, it is important to choose the correct tilt angle and orientation for optimal sunlight exposure, ensuring that there is no overlapping shading from the panels. Additionally, passageways should be reserved between photovoltaic arrays for cleaning and maintenance purposes. Therefore, the installed capacity of the solar power station must be determined based on the actual rooftop type.

How much electricity can photovoltaic solar panels generate each day? This depends primarily on the photoelectric conversion efficiency of the solar panels, sunlight duration, and installation angle. According to the notice jointly issued on June 8, 2015, by the National Energy Administration, Ministry of Industry and Information Technology, and National Certification and Accreditation Administration, it is specified that the photoelectric conversion efficiencies of multicrystalline and monocrystalline silicon photovoltaic solar panels should not be lower than 15.5% and 16%, respectively.

An important component of a photovoltaic solar power station is the photovoltaic array support structure. The load-bearing capacity of the roof is a key factor affecting the installation of the solar power station. If it does not meet the required standards, reinforcement of the building must be carried out to ensure safety and reliability. Furthermore, before securing the supports, it is essential to pay attention to the roof coating maintenance and waterproofing measures. Surrounding obstructions, such as tall trees or nearby buildings, will directly impact the effective sunlight exposure and electricity generation efficiency of the photovoltaic solar panels.

A professional and reputable photovoltaic power generation manufacturer specializes in these systems.
