An off-grid solar power system is similar to a grid-connected system, the difference being, an off-grid system uses batteries to store solar power. Excess power is not exported to the grid.
This is how an off-grid solar power system works:
Solar panels and inverters are considered normal components, but when you require an off grid solar energy system you will require a few extra components. Some of these include but are not limited to:
The type of battery you install will determine its life span. Most batteries last between 10 and 20 years. A 20-year battery will cost more, but when it comes to replacing a 10-year battery you will save yourself the extra installation cost.
Commonly used battery types include; lead acid, gel, sodium-ion and lithium-ion.
