Solar Energy System Overview
Solar energy systems are rapidly growing in popularity with the advent of more advanced solar energy system technology. These advances have made buying solar energy panels a much more viable option, as they are more reliable and efficient, thus producing more energy for your needs. Below is a helpful diagram of what we will overview: showing the typical components in most solar energy panel systems found today.
Solar cells are what do the actual work of collecting the suns heat and radiation energy, and the solar panels are a sort of frame that holds many of these solar cells together, so many of them can be conveniently mounted and positioned as needed. The number of Solar panels you need will vary according their wattage rating, your energy needs, and your budget. After the solar cells collect the suns energy, electricity is then sent through the charge controller.
The charge controller is what prevents your batteries from overcharging when they reach a full charge. Overcharging will damage your batteries, and can even be dangerous if you have lead-acid batteries which will release extra hydrogen gas. Newer more advanced charge controller's will automate your charging to ensure a longer healthier life for your batteries.

The batteries are where collected electricity gets stored, and without them, you wouldn't be able to save up your energy for when the sun isn't shining. For most uses, and for smaller budgets, you can just buy deep-cycle marine/rv batteries that will withstand numerous deep charging cycles(i.e. can be fully charged and fully depleted more times). If you want something a little more industrial strength, take a look into Flooded, Gel, and AGM type batteries.
Power inverters are what converts the collected DC electricity, into AC electricity which is used for common household appliances. You may not need a power inverter for a small system that only requires DC electricity, such as: small lighting systems, solar bicycle systems, and other portable solar applications: but, for most home, cabin/cottage/, and RV applications you will want AC electricity. AC electricity is used for powering things like: fridges, stereos, lamps, fans, washing machines, etc.
That basically sums up the 4 main components of a typical off grid solar energy system, but remember that there are various add-in type components you can add to your solar energy system for more advanced needs.
