Re the tax credit:
Claiming the solar tax credit for rental property you own
You can't claim the Residential Clean Energy solar tax credit for installing solar power at rental properties you own unless you also live in the house for part of the year and use it as a rental when you're away.
- You'll have to reduce the credit for a vacation home or part-time rental property to reflect the time you're not there.
- If you live there for three months a year, for instance, you can only claim 25% of the credit. If the system cost $10,000, the 30% credit would be $3,000, and you could claim 25% of that, or $750.
- $10,000 system cost x 0.30 (30% credit) = $3,000 full credit amount
- $3,000 credit amount x 0.25 (25% of the year) = $750 partial credit amount
