The application prospect of solar street lights

Battery in light made by electricity, solar panels need to night lighting when released again. With manufacturers to develop without battery solar street lamps system; By the control circuit to switch

battery store electric energy from the solar panels, illuminated and released for lighting at night. Some manufacturers have developed without the battery solar street light system. Solar battery and power grid in parallel. Switch is performed by the control circuit. Less investment and saving the cost of operation maintenance, low energy consumption, the system runs stably. Suitable for urban network near the street lamp, courtyard light and advertising light boxes. Focusing solar street lamps system with accumulator. 1. Capacity to choose battery capacity is too small, cannot satisfy the needs of night lighting. If a battery capacity is too big, will remain the state of power, this will affect the service life of the battery and wasteful. Battery capacity ( Ah) With the load capacity ( Ah) Ratio should be greater than 3 ~ 6 times: continuous area should be greater than 3 ~ 4 times less rain, continuous rain area should be greater than 5 ~ 6 times more. 2. When the battery is connected in parallel, should consider the imbalance between the individual cell. The number of parallel group should not exceed four. Pay attention to battery guard against theft.
