Green State Power - Electric Vehicle Fleet Charging System

The great part about this is that if you’re gone during the day and your panels generate more energy than your home is using, that extra power will be sent back to the grid spinning your meter backwards!  When you come home at night and use utility power again, you are getting that power back from the utility company you sent to them earlier in the day.  The utility acts like a giant battery for you with no power loss.

Using batteries on the other hand can decrease system output by 20% or more, because the chemical process of storing electricity in batteries is inefficient.  Batteries can also almost double the cost of a PV system, making a return on investment much more difficult than compared to a net-meter system.

In locations where there is no utility grid, off-grid systems can be wonderful by eliminating the need for large generators that constantly need to be supplied with fuel.  Instead, using a solar PV system with batteries can be your generator, with the sun providing all the fuel!
