off grid solar system

In some kind of solar photo voltaic system called Off Grid system, your solar system will incorporate batteries that can feed your loads with electricity in case of low sun radiation and night time. But such batteries add a significant cost to your solar system, so it is usually recommended to be used in remote areas in where there is No regular electricity supply exists.

We need to calculate how much energy our loads will need per day, and this can be done simply by knowing the wattage of each device and how many hours it works per day, multiply the wattage per each device by its run time and add all the wattage hours for all device, so can get total energy required for your home per day. Due to losses & inefficiencies, we recommend to multiply total watt hour by 1.5 factor.
