Major Types of Solar Power Systems

Solar Direct (or Day-Use Solar)
These systems do not have any storage batteries and are intended to be used only when the sun shines.
Without storage batteries, the power stops as soon as the sun goes away.soon as the sun goes away.
These systems are best suited for certain water pumping applications, venting fans, and certain electronics. Rare in application, they are very affordable and easy to install.

DC System with Batteries
These systems are great for small electronics that need to run day or night. Often times you’ll see these systems employed on highway sign lights, gate openers, and communication boxes. Simple and
affordable these systems have a wide variety of uses and are perfect for remote locations that require low voltage.

Hybrid Solar-Generator Systems
Most folks turn to a hybrid system for off-grid and back-up power applications. The hybrid system
generally consists of a PV array, a charge controller, a battery bank, an inverter, and sometimes a tertiary power source such as a wind turbine or a gas generator. This type of system is fairly complex and will require a high level of expertise to design and install. With the popularity of off-grid living, however, there are more and more packaged systems for people to choose from. These systems will provide power if the grid shuts down and can still sell power back to a grid if desired.
