From an engineering perspective, the grid is a tremendous resource. A grid-tied PV system will be more efficient, arguably greener, and certainly cheaper than a backwoods one. More efficient because the inverter can track the modules "maximum power curve" rather than the lower voltage needed to recharge batteries. Arguably greener because you don't need batteries, which contain caustic chemicals, emit sulfurous gases, and eventually wear out. And much cheaper because, with the grid as backup, you don't have to buy batteries, charge controller, control panel or generator.Right there, you've knocked up to $5,000 o...
