Can you claim a solar energy credit if you made a payment in 2020 but the system wasn't installed until 2021?

For example, I paid a deposit on the system in 2020 and then paid the balance when install was completed in 2021. Can I receive a tax credit on the deposit since the cost was incurred in 2020?

Since the installation was not completed until 2021 you will have to claim the credit on the 2021 tax return filed next year.
