Introduction to rooftop distributed photovoltaic power generation

Publish Time:2021-07-13 Sources:

Rooftop distributed photovoltaic power generation refers to photovoltaic power generation facilities characterized by self-generated and self-use on the user side, surplus power to the Internet, and balance adjustment in the power distribution system on the roof of the user's building. Rooftop distributed photovoltaic power generation is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principles of nearby power generation, nearby grid connection, nearby conversion, and nearby use, which can not only effectively improve the power generation of photovoltaic power plants of the same scale. At the same time, it also effectively solves the problem of power loss in boosting and long-distance transportation.


Types of distributed photovoltaic power generation on the rooftop of Grace Solar:


1. Roof support system (tripod)

The new GS triangle bracket system is suitable for roofs and grounds with a certain angle. This new triangle bracket is light, flexible and strong. It is easy to assemble and can be done with one tool. It can also be folded during packaging, and can be used together with other products of our company.


2. Roof support system (hook)

GS roof hooks are suitable for color steel tile roofs, magnetic tile roofs, asphalt shingle roofs, etc. It is fixed with roof beams or iron sheets, and the appropriate span is selected to resist the corresponding load conditions, which has great flexibility. It is applied to common framed solar panels or frameless solar panels installed in parallel on the inclined roof, and is suitable for the design and planning of commercial or civil rooftop solar systems.


3. Roof support system (adjustable feet)

The new GS tilt bracket system is suitable for roofs and grounds with a certain angle, and is one of the best designs in the company. This new tilt bracket is light, flexible and strong. It is easy to assemble, one tool can complete the installation, and it can also be folded when packaging, and can be used at the same time with other products of our company.


4. Roof support system (fixture)

GS roof fixtures are suitable for color steel tile roofs with great flexibility. The clamp and the color steel tile are clamped and installed without drilling holes. According to the needs of the project, you can choose between the rail type and the non-rail type, and the installation is as convenient. It is applied to common framed solar panels or frameless solar panels installed in parallel on the inclined roof, and is suitable for the design and planning of commercial or civil rooftop solar systems.


Features of Grace Solar rooftop distributed photovoltaic power generation:


1. Low pollution and outstanding environmental protection benefits. The rooftop distributed photovoltaic power generation project has no noise and will not pollute the air and water during the power generation process.


2. It can coexist with electricity generation. Large-scale ground power station power generation is step-up connected to the transmission grid and only operates as a power station; while rooftop distributed photovoltaic power generation is connected to the distribution network, and power generation and power consumption coexist, and it is required to be absorbed as much as possible on the spot.


3. The output power is relatively small. Generally speaking, the capacity of a rooftop distributed photovoltaic power generation project is within several kilowatts. Unlike centralized power stations, the size of photovoltaic power plants has little effect on power generation efficiency, so the impact on its economy is also very small. The return on investment of small photovoltaic systems is not lower than that of large ones.
