6 FAQs about [Solar cell power failure protector]
What is a solar cell-protector?
The purpose of the cell-protector is to prevent overheating of the solar cells when the solar module is partial shaded (Hotspot), this is achieved by the diodes on the cirquit board. ( By standard aluminium framed glass modules these diodes are located in the junction box on the backside of the modules.)
Why should you install a solar surge protector on your PV system?
So, when you install a solar surge protector on the PV system, it helps the system run smoothly without sudden surges. As a consequence, the system delivers a better and more consistent performance. Sudden power surges lead the PV system components to degrade with time. It gradually reduces the life expectancy of the solar power system.
What causes a solar panel to fail?
They found that the most common causes of early failure are junction box failure, glass breakage, defective cell interconnect, loose frame, and delamination. A study by DeGraaff on PV modules that had been in the field for at least 8 years estimated that around 2% of PV modules failed after 11–12 years.
