34. The life of the life of the solar panels on the roof solar panels solar power, solar power system tempered glass, EVA, TPT and other materials is determined by the cells, usually with better materials manufacturers of solar panels made out of life It can reach the 25-year solar capacity, but with the impact on the environment, solar panels material will change with time and aging. Normally used in power for 20 years will be attenuated by 30% for 25 years to use power will be attenuated by 70%. Inspection and Maintenance 1) Check whether the damaged solar panels, to achieve timely detection and timely replacement. 2) Check the battery cables and the ground plate is good contact, without loss phenomenon. 3) Check the wiring at the combiner box if there is fever phenomenon. 4) Check the battery plate bracket loose and breakage. 5) cleaning up around the shielding panels panels weeds. 6) Check the battery plate surface for covering. 7) Check the guano on the panel surface, and clean it if necessary. 8) on the cleanliness of the panels were identified. 9) to deal with high winds panels and frame to conduct audits. 10) snow days to respond panels were cleared up, the panel surface to avoid the frozen snow.
