Has any CTEC customer achieved their expected annual kWh savings? For the second year in a row the panels installed will generate less than 90% of the engineered design. CTEC guarantees as low as 80% of designed production. The system seems to be designed to generate between 80-90% of the guaranteed annual kwh. Given this design the financials for solar power using CTEC don’t appear to be worthwhile. When I inquired about the shortfall last year I was told that the panels do better in the second year. I’ve spoken with neighbors who installed the Tesla system and they’re over achieving their contract.
