We paid our nominal system deposit (1/2020) and signed our contract (2/2020) and had our install (8/2020-9/2020) and received PTO/PGE (10/30/2020). Our contract back in early 2020 was 1/2 contract price paid on first day of install and balance after PTO.
Some of the following may be out of order but this all happened prior to day of install for us. There was an initial design; revised design; contract and various paperwork prepared; several hours with our advisor by phone answering our questions on contract, our needs and procedure going forward; a 3-line drawing along with entire plan done (multi-pages if you never saw a copy); they submitted permit to city along with plan and fees paid on our behalf and got approved; we added another PW before install so revised drawings had to be done; city said they needed them to submit an additional permit just for the 3rd PW and wouldn’t revise our original permit so more fees required to be paid on our behalf. Scheduling department called with install date; their warehouse team pulled together necessary equipment required for the job and solar and PW teams (5-6; 3) were dispatched. Somewhere along the line staff was working with PG&E with paperwork and fees.
Install date we paid 1st payment. Teams arrived for install in several vehicles; were there over several days; a change was made to the solar panel layout which had to be approved in ofc and a revision to plans done for final submission to city; they set up inspection and Tesla guy arrived to meet and go over system with inspector. Passed. They submitted paperwork including single-line drawing to PG&E and paid any remaining fee due. Took PG&E almost 30 days to send us email we had PTO approved.
Up until this point based on our contract Tesla had laid out a lot money on our behalf to cover various employees time, plans, various permits, our solar panels, PWs and related system equipment. We also had one guy come out to repair a severed outdoor light fixture wire that happened during solar install and bring out breakers still needed (during covid several breakers needed were sold out everywhere and we needed to wait til inventory came in), and there was the drywall guy who spent several hours repairing drywall as some of our existing equipment on our interior garage wall needed to be moved for our install. All done before inspection could happen.
After getting PTO we called Tesla and made our final payment. I’m under the impression Tesla changed up scheduled payment requirements sometime after we signed. Instead requiring a larger deposit but no payment until install was done and before PTO would be submitted. If so that’s quite a lot of work and materials and fees laid out in advance. I can see why they would require payment before PTO so they were assured of getting paid. We thought our contract was fair at 50/50, but “a single payment prior to PTO” requires Tesla to layout a considerable amount of money for a longer period of time whereas you hold on to your money longer. We’ve had several construction projects done at our house and all had a partial upfront payment and then scheduled progress payments required. No idea how other solar/PW companies set up their payments but I don’t think prior to PTO sounds unfair given you’ve had inspection and know you’ve passed at that point.
