OC, the leases aren’t like regularly leases, that’s why system are over-sized. The lease is more like a discounted car rental than a long term car lease.
You pay a discounted rate for KWH used whether produced by the utility or the panel on your roof.
Any net excess production credit goes to the operator, not the homeowner. The economics of panels and inverters favor oversized systems. A 10% cost increase for the inverter and you can double the number of panels. The panels themselves aren’t that expensive, the labor is as much and the labor cost is frankly the same whether you install 15 panels or 30 panels. When we installed ours that’s what we did, nearly doubled the system capacity for right around 10%.
Except for the selling issue, leasing is pretty attractive.
