Grid Intertied Solar without Batteries... This is what the Federal incentives and State rebates are encouraging you to buy. It provides you with electricity which is less expensive in the long run. It also increases the amount of energy available through the Grid because electricity in excess of what you use is routed into the Grid. But when the Grid goes down, your house is also without electricity. Look at sample Solar Gridtie Systems.

Grid Intertied Solar with Battery Back-up. When the grid goes down you can still run some essential loads IF you have a battery backup system.

Grid Intertied Wind Power Systems produce power with wind generators. They can be set up with or without emergency back-up power. Look at sample Wind Gridtie Systems.
