How to Calculate Battery Capacity for Solar System?
The ratio depends on several factors, such as your daily energy consumption, location, energy needs of your solar setup (backup or off-grid), and budget constraints. For most applications, a good rule of thumb is to aim for a 1:1 ratio of batteries and watts or slightly more if you live in regions with limited sunlight, such as near the poles.
Although there is a carbon footprint associated with solar panels, the life-cycle emissions of solar electricity are around 12 times less than natural gas and 20 times lower than coal. And unlike burning fossil fuels, there is tremendous potential to further reduce the carbon footprint of solar panels.
