What components do I need for an off-grid solar system? - Monday 10 October, 2005
There are many components that make up a complete solar electric power system, but the 4 main items are: solar modules, charge controller(s), batteries and inverter(s). The solar modules are physically mounted on a mount structure and the DC power they produce is wired through a charge controller before it goes on to the battery bank where it is stored.
What components do I need for a grid-tie system? - Monday 10 October, 2005
Grid-tie systems are inherently simpler than either grid-tie with battery back-up or stand-alone solar systems. In fact, other than safety disconnects, mounting structures and wiring a grid-tie system is just solar modules and a grid-tie inverter!
