Pv energy storage system manufacturer price list

The design scheme of photovoltaic energy storage system is very important and can be said to be the soul of the whole project, which affects the cost of the project and the later operation of the system. For a simple example, although both off-grid and grid-connected power generation are photovoltaic power generation, they are very different in terms of design and installation. Grid-connected power station is designed to maximize the annual power generation. Therefore, the tilt Angle of the photovoltaic module should be integrated with the power generation situation of each month throughout the year. For the place with good photovoltaic resources, the Angle of the photovoltaic bracket is roughly the same as the local latitude. If the local is cloudy and rainy and the air humidity is high, the Angle of the photovoltaic bracket should be lower than the local latitude. In the off-grid design, the consideration is that the monthly power generation of photovoltaic modules can meet the power demand of the load. We know that the summer light time is long, the photovoltaic module has high power generation while the winter light time is short, the photovoltaic module has low power generation. So in order to ensure the power generation of photovoltaic modules in winter, when we design the tilt Angle of photovoltaic bracket, It's a little higher than the local latitude. Therefore, we must find an experienced manufacturer when purchasing photovoltaic energy storage system. Some customers consult the price list list of photovoltaic energy storage system manufacturers. Today, Huannu will give an example of this problem.

1. Prices of photovoltaic energy storage system manufacturers

Note: The design scheme of the whole system varies with the load power. The user needs to provide the specific electricity demand of the project before the manufacturer can provide the specific quotation.

2.Installation of photovoltaic energy storage system

For experienced manufacturers, they must know that the installation of photovoltaic power stations is also very important. When choosing a site, we must ensure that photovoltaic modules are free from shadow for 3 hours around noon. Field wiring is also very important, inverter, controller as close as possible to the photovoltaic array, reduce the length of the line, the shorter the line, the smaller the internal resistance, then the efficiency of photovoltaic energy storage system will be higher, and the line is short, will also save the cost of the project, we do not underestimate the light volt line these small accessories, the number of words, is also a large amount of expenditure.
