some user units installed solar street light and solar power generation system that can use it once and for all. After a long time found that less and less, the light is not bright, I do not know what to do. The causes of this situation are as follows: in addition to solar street lamps factory quality of the product itself have a problem with installation, mainly dust too much or the winter snow cover panels, photoelectric conversion rate' Photoelectric conversion rate, it is to point to in the solar photovoltaic system efficiency of the solar panels to convert sunlight into electricity. 】 Fell, the under charge, the battery power is not enough. Timing can remove dust can keep every time sufficient absorption to light source, can keep the photoelectric conversion rate Conversion turnover thewire, turnover rate in a certain community, community and ecosystem, standing crop ( Individual number or biomass) Are in a stable, input amount in the agreed upon period of time ( Or output) On the ratio of standing crop called conversion rate. 】 Not falling, ensure the battery scrap in advance due to lack of charging for a long time, keep clean can prolong the service life of the panels, due to the conversion rate does not decline can also decrease the cell number of floor tile save investment cost of panels.
