Solar street light panels, how to calculate the capacity

Now our solar street light manufacturer to teach you to calculate the capacity of solar module, according to the algorithm remarkably surface, if use 210 watts, calculate the solar street light panels capacity there is a condition, is the consumption of electricity supply back in the day, a day that is every day power consumption is 16. 4 when Ann. According to the available around the sunshine time is not the same, assuming available sunshine time, effective time is four hours. 16. 4 divided by four hours, when Ann is equal to 4. 1, Ann for photovoltaic panels in 12 v system is usually with 17. 5 v, in 24 v system with 35 v photovoltaic panels. So 30 watts lamp normal choose 17. 5 v of photovoltaic panels, this is the nominal voltage of photovoltaic panels, I 4. 1 multiplied by the 17th. 5 v will reach 71. 75 watts, and at the same time take into account the dust, shade, rain and snow ah factors such as loss, photovoltaic panels in the middle of the line loss in the charging process. According to 15% of the loss to deduct, 71. 75 watts divided by zero. 85 is 84 watts. Meet the application of such a situation, photovoltaic panels will need to achieve 84 watts. Actually this calculation we see a lot of parameters, are variable. So according to local actual application situation and the demand of different calculation.
