how to calculate off grid solar system ? When purchasing a off grid solar power system, many customers have this question: How much area do I need to reserve for off grid solar power system?
You will get clear reply after reading this article.There are two conditions for the placement area of solar panels:
1. Solar panels are installed on the roof
The installation area of one piece solar panel is estimated to be 2.1-2.2㎡. (The gap space between the solar panel and the solar panel is reserved.)
The solar panel installation area calculation method of the whole solar power system: the number of solar panels x 2.1/2.2㎡.
2. Solar panels are installed on the ground
The installation area of a solar panel on the ground needs to be calculated as 2.5 ㎡.(Because the solar panels are installed at a certain angle, in order to prevent the front solar panels from blocking the rear solar panels and cause the hot spot effect. Therefore, the calculated area of a single solar panel is 2.5㎡)
The calculation method of the solar panel installation area of the entire solar power system: the number of solar panels × 2.5 ㎡.
The solar inverter, solar controller and battery are recommended to be placed in a ventilated and dry room. (It is recommended to place it in a room close to the solar panel to reduce line loss)
For example:
5KW home solar power system: uses 16pcs 350W solar panels and 8pcs 12v200ah batteries.
.Solar panel installed on the roof: 16pcs x 2.2㎡=35.2㎡, which is 36㎡
.Solar panel installed on the ground: 16pcs x 2.5㎡=40㎡, which is 40㎡
The solar inverter and battery need to be placed in a room of about 5-10m³
