There are new solar tiles that integrate with your existing roof tiles (for aesthetics) and connect to a DC->AC invertor in your house. The average installation for a 12x30ft grid costs about $25k after rebates which over 30 years at 7% is about $15/month. Such system should generate about 5,000 kWh/year. Your system is still connected to the grid so if you need power and there's no sun, it comes from the electric company. Moreoever, you'll generate more in the summer than winter which is automatically sold back to the electric company. i.e. your meter runs backwards. There is no sales tax or property tax on the system. If you also put in some batteries, you effectively have a whole house UPS.
