I want to create a depreciation method that supports green energy

Summary:

I want to create a depreciation method that supports green energy.
My goal is that the total annual depreciation will be the same, divided equally over the years of the asset’s life.
But within the year, the allocation of depreciation between the months will be different — for example, in June the depreciation percentage will be higher and in January it will be lower. Different percentages between the different months of the year.

What’s important is that if the asset starts operating only in June, then it will take the June depreciation percentage as the starting point for the calculation.
