California laws will boost residential solar installations

gosolarcaliforniaOn the heels of Jerry Brown’s return from the U.N. Climate Summit in New  York, the California Governor signed a law to streamline rooftop solar installations. Assembly Bill 2188 puts some requirements in place that will require cities to establish expedited review checklists, allow electronic signatures and finish any inspections within five business days of a request.

To date, according to information provided by, there are 140,000 completed residential solar installations in the state adding up to over 800 MW of solar capacity.

As you can see from the chart below, solar installation costs for residential customers (both direct purchase and leased from 3rd-parties) has been steadily decreasing over the past few years. Hopefully the changes enacted by law today will help this trend continue.
