Do I deduct Solar Panel costs in the year they were installed or the year I paid?
Greetings! I had solar panels installed on my residence in December of 2022. I paid half of the invoice in 2022 and half in January of 2023. Can I deduct the whole amount of the invoice on my 2022 return, or do I need to deduct part this year and part in 2023?
Thank you kindly for your insights.
Dave
