The savings with solar can be substantial for homeowners with electric bills topping $100 a month. Randy Zechman, the CEO of Clean Solar, a Diamond Certified company, suggests the first step is to review your PG&E bills for the past 12 months to determine how many kilowatts you’re using and what you’re paying. This helps solar contractors, who have to be licensed, know which size system to install in your home.
Rather than depend only on a solar contractor’s representations as to the amount of energy a system will produce, ask for what’s called a solar production guarantee. Get this in writing along with the warranty. Mr. Zechman says you can still get federal tax credits and rebates from the state for installing a solar system. The federal tax credit is now 30% of the cost of the system, and the state rebate is 25 cents per kilowatt.
