What part wasn’t worth it? You said it’s not worth it, then made it sound worth it.
The ROI is 10-25 years based on the electricity prices you locked in at the start.
With regular inflation, and general increases in the electricity rates, over the long run you’re going to save money. The return might not be investment market level returns, but if you can justify the up front costs it’s unlikely to not come out ahead.
