so if you produce 181.14kWh (export 112.75 and self consume 68.4) that means your production is worth
112.75 * 0.085 + 68.4*(0.085+0.08) = $20.87
My point is that $20 isn't worth it for me to spend the time to clean them, risk damage to the panel, or injury to myself (I've seen the panels shed snow and I wouldn't want to pull that down on me)
Here are my numbers
October 22 2021 - November 21 2021 = 531 kWh
October 22 2022 - November 22 2022 = 147kWh
I've been covered in snow since November 1, but still for 400kWh were talking $40 potential, so maybe over the course of the whole winter it's a couple hundred, but it's still a drop compared to generation in the summer.
My panels make 11,000kWH/year and make about 10,000kWh during the "export months" when they are valued at $0.285/kWh.
If I miss out on producing 1500kWh during the winter that is also at the import rate of $0.085/kWh. so that 1500kW only accounts for less than 4% of my annual revenue.

ROI is one thing, I like having my house covering its own usage and putting back on the grid whenever possible. That's why if it was practical I would totally clear my panels.
