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!

Best in the eyes of the inspector on install and customer service: 1. Freedom Solar 2. Sun Power The quote,design,approval by HOA,electrical install and panel install was painless. Tesla is providing batteries for solar installations. We opted to have a battery.

I had one good experience with these guys when then installed a tesla charger at my old house and…read moreat terrible experience with them with they installed a tesla charger at my new house. The first time they did it they installed a 240 volt outlet in my garage and I plugged a tesla mobile connector into that, worked well. The next time they did it at the new house, I thought they would do the same thing but apparently they stopped installing the mobile connectors. Now they only install the wall connector which is a large sci-fi looking thing that is permanently affixed to the wall. It's also more expensive than the mobile connector. None of this was made clear to me when we started the project with Grayzer. They came to my house, got about 90% done with the job then saw the equipment I had and said "sorry we don't do those anymore". They explained the situation to me but since I didn't have the equipment they wanted they couldn't finish. They did however insist on being fully paid for the job. Stupidly, I agreed to pay them and they left saying "call us when you have the wall connector". That was a mistake. Never fully pay for the work until the job is fully done! So I bought one and scheduled a time to finish at which point they said they would need to charge another trip fee to come back out. I explained that it wasn't made clear to me that I didn't have the right equipment until the job was almost complete but they didn't care. They were insistent that I give them another trip fee before they would come back. Frankly they were pretty rude about it too. Like really rude. Whoever I was emailing was belligerent and completely unprofessional. It was extremely frustrating. I tried to explain that as the professionals in this situation they should be the ones checking that all the equipment is ready to go before the job starts. At the time I didn't know the difference between a mobile connector and a wall connector. I didn't even know that tesla had multiple options for wall chargers. I had what I used the first time so I figured it would work. It's not that the trip fee was so much money but after having to drag this out over two visits, spend another $150 to upgrade to a wall connector, a trip fee on top of all that was a bit much. In my opinion, a reasonable company would just accept responsibility and waive the second trip fee. Or at least offer to split it. But not these guys. They dug their trench and they weren't coming out. It was childish and stupid and I'm embarrassed for them. And to boot, the people they sent out to finish up the job were jerks. One of them was yelling and cussing at somebody on their phone like a crazy person in my garage. Honestly, these guys are like school on a Sunday -- no class. I guess this is what happens when you get to be a popular company. Customer service and basic decency goes out the window because what do you care, you have plenty of business. Right? Yeah right.

So I was in the process of adding a Tesla Wall Connector to my home. I sent out a request to three…read moredifferent companies ( all Tesla Certified installers ). All were prompt in their responses and provided well written proposals. Only Grayzer included the cost of a permit in their proposal. Further a friend had their wall panel upgraded and their Tesla Wall Connector installed by Grayzier and recommended them highly. After looking at the reviews for the different certified installers, and given that a permit is required in my town to install an EV charger, I went with Grayzer. They provided a date and service window ( a week in advance of my appointment ) and the electrician, Max, pinged me about an hour prior to his arrival. I showed Max my ideal location for the Tesla Wall Connector and he was able to accommodate without having to cut away any drywall or running conduit outside the wall ( YMMV ). Very friendly, professional and knowledgable. He took the information/pictures required by Tesla and by my town's permitting authority, commissioned the Wall Connector, showed my how to add it to the Tesla Application on my iPhone and verified that it was charging at the specified rate (48 amps). He was happy to answer any questions I might have, and I am just delighted by the service and work done. I would recommend highly to friends, neighbors, et al. All in all, quick, fast, efficient, and professional. Cleaned up work area when done. Thank you!

We went the DIY route, measuring and installing 6 solar screens ourselves. Ours is a new home with…read morealuminum-framed windows. The back of our home faces west, so the afternoon sun in the summer can be brutal. We bought the wider framed screens with a cross brace, since our windows are rather large (35" x 70"). We chose 90% screens because of the western exposure. Ordering the screens was easy, particularly since all of the windows we wanted to screen are the same size. But our windows have narrow recessed edges so we weren't sure at first about installation. We didn't want to void the window warranty by using screws. So we sized the screens to match the protruding portion of the windows and purchased heavy-duty outdoor Velcro strips (1" x 4") to attach the screens. Our process was to attach the fuzzy side of the Velcro in the same location on the frame of each solar screen. This made them all interchangeable. Then we put the matching half of the Velcro in place on the screen. Lastly, we removed the backing, lined up the screens, and carefully put each screen in place, pressing firmly to secure. We chose to attach Velcro only on the sides of the screen frames, for ease of removal when we want the sun's heat and light in the winter. The frame color we chose closely matches the original window frames and house trim, and the black screen matches our screen porch, so the solar screens look very much like they belong. I recommend you be choosy when selecting frame and screen colors, as they can change the overall look of your home. Picking up your DIY screen order is an efficient process: when the screens are ready (ours took about a week), an email arrives with directions to a small industrial park, a code to enter the stowage space, and the location within of your screens. Once inside, there are doors to compartments that contain orders. This is how 24-hour pickup is made possible. My only gripe, a minor one, is that one of the 6 screens has an obviously darker area, perhaps a crease in the fabric. But, all in all, this was a great experience. We expect our west-facing rooms will be more comfortable this summer than the last one.
