Just received my first bill with the system in place. The only charge we have is $16 for being connected to the electric company. We have banked 187 kWh with the electric company that can be used in future months if necessary, or paid out on an annual basis next year.

Hi J K, Welcome to the wonderful world of solar!! We jumped in March 2013 and at the time our cost per watt at the time was $3.80. Thanks to the 30% Fed rebate (make sure you do that) and PA had a program back then that made our final cost $1.90 a watt.
Our entire house is electric and we have no access to natural gas, so our system is much larger at 42 panels to do out heat, AC and all of our demand. That now includes a plug-in hybrid Chevy Volt, so all of my driving is "free" and green. The only time I burn gas is when I drive about 1000 miles for vacation each year.

This and my basement are my next projects. I recently had my roof replaced and I wonder what happens if there is a leak after solar installation, would the solar company eat it or the roofing company? How are you protecting the panels from squirrel or bird nesting? Is your attic now hotter or cooler with panels on top? Is the big inverter better than the micro inverters, was there a cost difference on your package for the big inverter? Are you expected to clean the panels yearly or is the company offering that service? Did that company have a battery bank system what was the cost difference?

Its really nice. It worth it to going solar rather than wasting thousand s of dollar paying to the electricity companies.
