Among the technical parameters of the inverters, there is a maximum allowable access power. It is necessary to consider illumination conditions, installation site, components and inverters.1.

With the popularization of distributed photovoltaic power generation, roof power plants have gradually entered the daily life of our residents. Many households have installed roof photovoltaic power stations.

There are two typical applications of photovoltaic, grid-connected system and off-grid system.

Batteries are self-discharging. If they are not used for a long time, energy will be lost. Therefore, regular charging and discharging are necessary.

Lead-acid battery generally adopt three-stage charging mode:The first stage: Fast charging mode and constant current charging stage. The discharge depth is closely related to the battery life.

​Because of the difference of the pre-production process between monocrystalline silicon and polycrystalline silicon, there are some differences in their appearance and electrical performance.

With the continuous strengthening of people's environmental protection concept and the importance of clean energy, roof solar power generation has gradually been popularized. The public has gradually understood and recognized this clean energy.

Compared with other places, the school has the following advantages in building photovoltaic power station :
