This month it was my first year anniversary with Tesla Solar Panels and Powerwall. My setups is 12.8 kW Solar Panel System (Estimated energy produced: 16,138 kWh/yr) with 1 Powerwall.
In this first year total generation was 10kWh. Some 55% of the estimate Tesla gave me when I purchased the system.
What options do I have to complain and get the system fixed to produce the estimated energy? I wouldn´t have installed the system if the production would have been so low.
I already contacted Tesla twice (first time they disregard my complain, now they say they are analyzing the data, but I don´t have much hope that anything is going to come out of this).
I understand that an estimate is just that, an estimate, but I would expect the real numbers to be +/-10% of the estimate. Maybe +/-15%. In my case it's a huge difference.
This is the fist year, so nothing changed as to justify the lowre performance. Solar panels are new, no trees have grown to cover the sun over the panels, no new buildings, anything whatsoever.
For instance, July, which was mostly sunny here in Houston (I think we didn´t have rain like in 3 weeks) and which should be the month with highest production, the system only generated 950kWh. If we factor in that there are a few days still in the month, let's say I'm going to have generated 1150kWh. Which would equate to 12,000kWh in the year, still way lower than estimated by Tesla when I purchased the system.
