Good start, terrible follow through
Everything was great to start but now that my system is in and working. I have been trying to contact them for over a month now with nothing but an automated response. The system they installed isn't preforming as to the specs they said. I am suppose to have a 10.1KWh (25 panels, 405w each) system and on the sunniest days every panels never show over 350w (making it a 8.75KWh system)
- Approximate cost of services:
- $25,000.00
- Company Response
Hi! We're sorry to hear this and definitely understand the importance of quick responses, especially regarding questions about new systems. We want to hopefully clarify these production numbers to provide some peace of mind regarding your system.
The 10.1kW size shown in your proposal is referring to DC size. On the other hand, the production numbers you're seeing on your monitoring app and inverters are in AC size. It is very standard to have a bigger DC/AC ratio (around 1.25) in order to fully optimize your inverters for a longer period of time throughout the day. Your panels only work at maximum peak capacity for a short amount of time during the day. If panels and inverters were sized the same, your inverters would be under-utilized the rest of the day, which would mean less power. Having that bigger ratio allows your inverters to be working at capacity for a longer period of time and producing more energy during the mornings and evenings. Therefore, you are producing more power during the other times of day when the sun isn't at its peak.
Please rest assured this means the predicted kwh hours we provided on your initial proposal is still accurate. From our records it looks like the estimated yearly production amount is 11,295 kwh. Since your system was turned on in December, you've produced 7,192.32 kWh in less than 8 months. You are on track to meet these annual production projections by the one year mark of your system.
We hope that helps! Of course if you have anymore questions, please feel free to let us know
