Photovoltaic grid-connected inverter is an essential key component in photovoltaic power generation system. It is mainly used in the special inverter power supply in the field of solar photovoltaic power generation.
The grid-connected inverter converts the AC generated by solar panels into AC that can be directly divided into the power grid through power electronic conversion technology.
Sustainable energy makes the world a better place
Flying over Datong, Shanxi Province, you can see two giant pandas waving to the sky. This is an electric farm composed of thousands of solar panels. This 100-megawatt power farm covers an area of more than 100 hectares.
If only power generation is considered, the sooner the snow on the solar panel falls, the better. However, most of the houses in urban areas do not have enough space around the buildings and between the houses next door.
In this case, if the snow on the solar panel falls outside your own yard, it may cause damage or injury to the buildings, goods, and pedestrians next door.
1. High-quality hardware: under the policy guidance, there will be a more subdivided subsidy market and parity market in the user market. High-quality and high-quality brand development has become the mainstream.
The first is to select good materials and use the correct materials to ensure the excellent quality of each hardware. Strict monitoring must be carried out before leaving the factory to ensure high matching between hardware.
Solar panels work most efficiently at a temperature of 25 ℃ and then decrease with the increase of temperature. Therefore, researchers at the University of Kansas think about how to extract heat from solar panels when the temperature is too high.
After comparing three roof materials, they find that the solar panels installed on the “green roof” have the best effect, Compared with white or black roofs, the conversion energy is increased by an average of 1.4%.
“Pollution-free, radiation-free and profitable” green energy – Photovoltaic has set off an upsurge of photovoltaic applications all over the world. Well, in addition to the common photovoltaic roofs and photovoltaic walls What are the other applications of photovoltaic power generation? Have you seen them all?
Precautions for the construction of solar panel greenhouse: for the natural ventilation of greenhouse, attention should be paid to: the density difference of surface and interior exchange gases changed from the temperature difference between the outside and interior of the room, which drives the surface and interior exchange of the atmosphere;
1. Characteristics of B-type RV and C-type RV
B-type RV is small and flexible, with good driving handling and safety
Type C RV is larger, wider, and more comfortable, with a forehead on the roof
Roof solar panels are 79% cheaper than they were in 2010. These slumps make rooftop solar photovoltaic power more attractive to families and businesses who want to reduce their dependence on the grid and reduce their carbon footprint.
But is there enough roof area for this technology to produce affordable low-carbon energy for everyone who needs it?
When it comes to Saudi Arabia, the “oil kingdom”, rich economy and developed tourism leap out. From another perspective, due to the wide distribution of deserts in Saudi Arabia, the maximum temperature in summer can reach more than 50 ℃, which is undoubtedly a great test for the tolerance of electromechanical equipment placed outdoors for a long time.
As we all know, it is not only cloudy and rainy days and nights, but also muggy and hot weather that restricts the efficiency of solar power generation. Therefore, it is urgent to solve the heat dissipation problem of solar panels in the desert environment, so as to avoid that the power required for cooling is higher than that of solar power generation.
