My husband and I wanted to add solar panels to our roof, and we're so glad we went with 512 Solar…read more They were efficient, responsive, and within budget. We did our installation in 2022 and have seen our energy bills lower than ever before! (We have some shade on our roof so we didn't do the full roof, ~20 panels or so, but it worked out well.) They did the rebate work with the city so our out-of-pocket cost wasn't exorbitant at all. Our household also recently purchased a second electric vehicle so we contacted 512 Solar again, this time for a level 2 charger installation. Once again, 512 Solar was excellent at getting our quote together, suggesting two hardwired chargers that the city does rebates on, and actually getting the work done as well. We have to do the final step with submitting the rebate paperwork to the city, I believe, but that's small beans compared to all the work that JP and Huiyun did for us at the outset. Really happy we went with these folks and will continue to recommend their business!

The sales contact Jane is incredibly responsive and worked many different quotes with me with ease. There was an issue with the critter guard install but they came back out immediately to fix it.

Freedom Power team --…read more THANK YOU! Our system is the best advertisement you -- and Tesla -- could ask for. Our propane-generator neighbors are genuinely envious. There is no comparison. STORM TEST. Tesla installed our original Powerwall last March and Freedom Power added the extension battery this week -- two batteries now. Within hours of finishing, an electrical storm subjected the neighborhood to several hours of brownouts and blackouts. A few grow-lights flickered briefly. None of the clocks needed resetting. No noticeable latency -- Wi-Fi and everything else just stayed up. Except for the lightning and thunderclaps, we hardly noticed the storm. Rate math (FPL RTR-1 Time-of-Use). On-peak grid power runs about 29¢/kWh. Off-peak is about 6-8¢/kWh, and off-peak includes a real credit, not just a smaller charge. PRE-EXTENSION PACK. On our latest bill (1,671 kWh): only 61 kWh on-peak (3.7%) and 1,610 off-peak. The TOU structure saved us roughly $67 (July) versus the same usage with no off-peak credit. Every peak kWh we avoid is worth about 21¢ against off-peak. YESTERDAY'S LOAD TEST. Stove, hairdryer, showers, Instant Pot, TVs, computers, and air conditioning at 77°F -- and we still had 31% battery left at 9 PM, the end of the summer peak window. Under the single Powerwall we often scraped the last two hours and leaked expensive peak kWh. With the second battery, we held the whole peak on reserve with room to spare. When Elon offers vehicle-to-home (V2H) power-sharing in something nicer than the Cybertruck (wife hates the look), we'll add that to the backup stack. Solar roof tiles still feel like overkill for us -- but you've earned enough trust that we might change our minds. I already have one referral in the tunnel. I'll let you know when it lands. Our thanks to Joshua Leathers and the entire team at Freedom Solar Power for their performance and professionalism.

I was referred to Cool Roofs and since the initial phone call with Kevin, and then the inspection by Colt, I can safely say that anyone I know who needs a roofer is 100% getting this contact card from me. You can tell they're totally in your court, they're insanely efficient at getting you solutions and they genuinely care about doing a great job. It's rare to get a company these days that isn't full of crap, but Cool Roofs is certainly one of the good guys! Looking forward to having them in my address book for a long time!
