This weekend is the National Solar tour. This is a great opportunity to go and look at homeowners solar system. You can talk to the homeowner about solar and look at their systems.
Most solar owners will give you an honest assessment of their solar projects, what they did right, what they did wrong. Costs of their systems and their results on the electric bills.
The best part of all of this, is that no salesman will be present.
