California Exemption from Property Taxes

As if you didn't need enough incentives to install solar electricity on your house, here's another:

California excludes all solar electricity system installation costs from being added to the property value of your home for property tax valuation purposes.

That means that if you add solar electricity and it increases the value of your home by some $34,000 + (for an average system of 4.0 kW DC; we'll show you how this happens as part of our financial analysis) for an out-of-pocket cost of some $16,000 (again, for an average system of 4.0 kW DC), the first $16,000 pickup in equity is completely tax-free.
