OUR SOLAR ELECTRIC SYSTEM
These are the specifications of our system. It is not a system which should be copied because it is a system which was inherited and then added to. If I was designing it from scratch I would make different decisions. The most important thing when designing a solar system is to buy enough battery power because it is very difficult to mix old batteries with new batteries. You may notice in the photo above that there are 3 charge controllers with 3 sets of panels. This does not seem to be a problem.
For a lot of the time it serves 7 people with a swimming pool pump, fridge, freezer etc. If the sun is shining I can boil water in a kettle.
