We have installed many solar systems across Sonoma County, usually in conjunction with a full Zero Net Energy retrofit. Zero Net Energy means producing just as much power as you consume, either mostly or completely offsetting your utility bill, 

We also install ground mount solar systems when rooftop solar is either infeasible or undesirable.  

Combining a solar system with battery storage can allow you to store power for outages and offset electricity costs when the sun decides to hide itself away.
