It will take 20 - 30 years to break even.

Solar produces power less then 50% of the day, and you need expensive equiptment to convert the DC from the solar cells to AC for your home. Even more equipment is needed if you want to sell your electricity back to the power company.

How to use solar roofing on 2010 prius?

We Answered:

From the manual:

The Solar Ventilation System may not operate under the following circumstances due to a lack of power from the solar panel:
Low amount of sunlight
Part of the solar panel is cast in shadow
Part of the solar panel is covered by fallen leaves or dirt
Solar panel is not at a high temperature

Make sure that the POWER switch is in ON or IG-ON mode before turning the solar ventilation switch on. If the solar ventilation switch is turned on while the POWER switch is OFF, the air mode and the status of the air vents will remain unchanged.
