How to design the solar panel racking systems to prevent overheated of the panel
Nov 24 , 2021
Overheating of the photovoltaic panel will cause its output power dropped. And may form a hot spot that will affect the life of the photovoltaic module. But this problem can be improved to a certain extent through suitable solar panel racking systems design. Flat roof solar racking Different from the traditional ballasted solar racking, this design is more ventilated and can save the cost of cemen...

How to Calculate Suitable Module in Off-Grid Power Storage System
Jan 07 , 2022
The design principle of the module in the off-grid power storage system is to meet the daily power consumption demand of the load under average weather conditions. That is to say, the annual power generation of the solar cell module should be equal to the annual power consumption of the load. Because the weather conditions are lower and higher than the average, the design of the solar cell module ...

How to select solar inverter and install it?
Mar 17 , 2022
The following points must be paid attention to when selecting and using the solar inverter: 1. The DC voltage must be matched. Each inverter has a nominal voltage, such as 12V, 24V, etc. It is required that the selected battery voltage must be consistent with the nominal DC input voltage of the inverter. Such as 12V inverter must choose 12V battery. 2. The output power of the inverter must be grea...

How to ground the household solar power storage systems
Mar 24 , 2022
The service life of a solar power storage systems is more than 25 years under the premise of that the equipment quality and installation process are standardized. Among them, grounding is a very important step. Improper grounding will cause an error due to the device’s low insulation resistance to ground or excessive leakage current, which will affect power generation and may even endanger persona...

How to slow down the speed of panel module power output decline on solar energy system?
Mar 31 , 2022
Solar module is an important part of the solar energy system. Solar module power attenuation refers to the phenomenon that the output power of the PV module gradually decreases with the increase of the illumination time. Some common quality problems in the production process of solar panel are also the main reasons for the power attenuation of module in the power generation process. 1. Silica gel ...

The benefits of roof mounted solar system
Apr 20 , 2022
Roof mounted solar systems can serve multiple purposes 1. The solar module of the roof can play the role of "regulating" the indoor temperature. It can cool down and keep warm in summer and winter respectively. In addition, the photovoltaic array absorbs solar energy and converts it into electric energy, which greatly reduces the comprehensive outdoor temperature, reduces the heat gain of the wall...

Why do off-grid power system need batteries
Apr 27 , 2022
Off-grid power systems must be equipped with batteries. The task of the battery is to store energy, ensure the stability of the system power, and ensure the load power consumption at night or in cloudy and rainy days. The system can only generate electricity when there is sunlight. Usually, the power generation is the highest at noon. However, at noon, the demand for electricity is not high. Many ...
