- Voltage To Use
It is the equipment that you use will make you know the best voltage you need from a solar panel. There is always the common voltage that they have to share. However, the majority of this equipment run with 12V, 24V and 48V inputs. It is therefore easy to match with solar panels in parallel or series configurations.
You might need to also use a higher voltage than 12V because it will be more efficient.
- Correct Solar Panel Size
So that you can know the solar panel you need, you need to know the energy that you will need from the equipment you use full day. So that you can make correct calculations, you can multiply the total power you consume by 24 hours.
