If it is a on grid solar power system,it doesn’t exclude the battery , the price is relatively easy to calculate. The grid-connected solar power system mainly includes solar panels, PV brackets, controllers, inverters, combiner boxes, cables, etc. Taking a 10KW grid-connected solar system as an example, the overall cost is about USD5700.If the solar system capability is Larger, the unit price per watt is lower.
For the cost of a home off-grid solar power system, this is really not easy to calculate. Let's take the common off-grid solar power system as an example. The biggest difference here is the configuration of the battery. The price gap is very large.
The size and configuration of the battery is mainly based on the configuration of the electrical equipment in the family. and also consider the cloudy and rainy conditions.These two factors are the key to effect the battery capability and price.
