Welcome to click here, I am very glad to give you a brief instruction about the solar related light which is a customized kind of product. It cnsists of solar panel, battery, solar charger controller and lamp, which is the most important configurations in solar light system.But for business, the price is also more important, so I would like to give you a example for your reference. For a 7W LED for 12 hours a day and 3 continuous rainy days, if the installation spot in NingXia province China, the general kits are 12V/40W solar pannel, 12V/38AH battery, but in any other installaiton spots,the general kits would be different,and the price is different too.So,generally speaking,for the solar related productions,the general kits depend on the daily solar radiation-horizontal ,the price depend on the the general kits.So,for one solar PV prouction,different installation spots, different prices.

So,if you are interested in our solar related productions, or you would like to buy these kinds of productions, please send your requirements to me with E-mail, I will reply you earlier and send you good general kits and best prices.I am sure you will find the best cooperater.
