Home solar power systems

Home solar power systems come mainly in two types :

1. Grid connected systems, mainly rooftop mounted which have an output in line with an average household demand. Main elements of which are an array of solar panels and an invertor to convert DC into AC 220v/380v. This type is connected to the main electrical grid this way if the output of the solar array is not enough for the current demand power is added from the grid.

2. Off the grid systems. These come with energy storage batteries and if so required with backup generators, this is a good option for homes in remote areas where the extra wiring costs for a grid connection are unfeasible. Price for such installations would be around 4-5 EUR per watt production capability.

In Spain grid 99% households are grid connected, despite electricity being the most expensive supply for most homes.
