Electrical Connection Diagram
According to the simulation of shadow occlusion, the current and voltage adaption caused by occlusion are calculated, and then the whole system design are optimized. (modules in the same array are same color)
Shadow Analysis Chart
Combined with meteorological data, geographical conditions, loss parameters (shadow, dust, electricity), modules, inverters and other parameters, a more detailed power generation prediction is carried out.
PV PLANT O&M
High efficiency and performance of the power station ensures safe, stable and reliable electricity revenue!
WHY NEED O&M？
It will be dangerous without professional O&M.
Maintenance contentS
1. Regular cleaning the modules, the surrounding environment; derusting the racking.
2. Aerial photography technology realizes efficient and accurate hot spot inspection; EL detection at power station side; terminal detection.
3. Detection of the inverter.
4. Maintenance of distribution cabinet.
