Baoding solar street lamps factory garden light common configuration

Applicable area: shandong and the surrounding plains with latitude customer requirements: LED solar garden light light high 3. 5 meters ( Solar panels high) 10 w, courtyard light source power, work every day 8 h, ensure to provide lighting for rainy days 3 days. 1 solar modules design configuration choose

used in: shandong and the surrounding plains with latitude customer requirements: solar LED garden light high three. 5m( Solar panels, high) , garden light source power of 10 w, work every day 8 h, guarantee for three consecutive rainy days lighting. 1 solar modules design and configuration: charging the area daily average sunshine time > 4 hours, calculated at 4 hours. Power consumption (courtyard light way 10/12) * 8 = 6 traffic light. 67 ( Ah) Battery charging current: ( 6. 67 * 1 05) / ( 4 * 0 85) = 2. 06 ( A) , including l. 05 for solar cell component system comprehensive loss coefficient. 85 is the battery charging efficiency. ( There are different brand system of solar panels and batteries ( Different brand system of some parameters of solar panels and batteries will be slightly different) 。 Based on this, the power of the solar cell module parameters have been calculated as: 2. 06×12 = 25( W) 。 2. Choose battery capacity battery: 6. 67 * ( 3 + 1) = 33. 34 ( Ah) , choose 24 v - 40 ah maintenance-free lead-acid batteries. 3. The controller select intelligent controller. Controller parameters according to the requirement of the street lamp system of zhengzhou to adjust. Street lamp battery well protection. 4. Solar cell oblique reference data: 35. 730 + 70 = 42. 750. The direction of the solar cell stack was SBW, Angle with the horizon for 42. 7505 degrees. Light wind resistance design is based on the construction of regional climate conditions to design the street lamp system assembly and light wind.
