Setting up a solar system can be intimidating, but once you understand the basics of a system, you can feel confident in setting up a system to fit your needs. There are 4 basic parts to a system which I'll explain below. You can get away with 3 parts though if you decide that is the best way to go once you understand how everything works.
Solar panels are the most visible (and usually the ONLY visible) part of the system. Panels are rated for wattage and voltage. You have to look at both, to make sure your system will work properly. Systems are usually made in 12 and 24 volt systems. You can do 36 or 48 volts, but those are generally more costly. 12 volt systems are the easiest to put together because there are more devices that run off 12 volts, like most automobiles do.
