yes 7% ROI if no depreciation, but neither panels nor inverter are expected to last much beyond ten years. I was actually chatting with him just now since I got into this discussion, and he said he also needs a maintenance/emergency ca

You need more information to calculate the ROI. I gave you the peak efficiency, Which comes from clean panels and no clouds. The average efficiency is closer to 70%. While the canaries are pretty sunny, the panels get dirty very quickly (fi

sorry yes. He told me, installation is 6,000 W and is about 91% efficient at peak. 12 460W panels. panels point in optimal direction. In spain he sells excess to grid at €0.04 per KHW. Lowest cost of importing is €0.085 for KHW at night, ab

The payback periods get me confused. A relative set up solar a year ago in one of the sunniest places in Europe, the Canaries, cost €7,000 for 6KW. He just ran the math on it and found out that the payback period is 15 years. The only way t
