The space required for an off-grid solar system depends on several factors, such as the size of the system, the type and number of solar panels, and the specifics of the installation location.
Generally speaking, the installation area of solar panels can be calculated based on the area and number of each panel. For rooftop installation, the installation area of the solar panel is usually estimated to be 2.1~2.2 square meters, taking into account the gap between the panels. Thus, the installed area of the entire system is the number of solar panels multiplied by the area of each panel. For example, if there are 16 solar panels, the installation area is about 35.2~36 square meters.
For a ground installation, the design area of each panel is usually 2.5 square meters, as the solar panels must be installed at an angle to prevent clogging and heat spot. Similarly, the installed area of the entire system is also equal to the number of solar panels multiplied by the area of each panel. In the example above, if there are 16 solar panels installed on the ground, then the installation area is about 40 square meters.
Please note that in addition to the space to install the solar panels, you also need to consider the space for the solar inverter, solar controller, and battery. These devices are usually recommended to be placed in a ventilated and dry area, preferably near solar panels, to reduce line losses.
Thus, the space required for an off-grid solar system varies from case to case, but can be roughly estimated by counting the number and area of solar panels. When planning and installing the system, you should take full account of the actual situation at the installation site and ensure that there is enough space for all components. At the same time, to ensure the efficiency and safety of the system, professional installation guidelines and recommendations should be followed.
