"I'm very happy with the service received from Schmitty's plumbing. When I called them about a leaky shower faucet, they were quick to respond and even quicker to solve the problem. They also offered to look at any other issues, and quickly fixed a garbage disposal issue as well. The price of the service visit was exactly as quoted over the phone, and was reasonable."

"SolTerra did an absolutely fabulous job and has been a pleasure to work with. :-) We initially contacted them over a year ago for an estimate so that we could plan for our installation, get a few estimates, and compare technologies. After doing exactly that, we reached back out to them to move forward with our installation; everything SolTerra had in their proposal (which had three energy options) reflected just what we were after: the latest Enphase micro-interters, 400W Solaria panels, Enphase control systems, LG batteries, and very good warranties. Throughout the entire process, Kevin was there to answer any questions that came up. Once we decided to move forward, SolTerra put us on the schedule and kept us updated on the tentative start date. We were initially looking at starting in June and actually started at the beginning of August - not bad given the disruptions of the pandemic. When the day arrived, so did SolTerra with 33 solar panels, mounting hardware, and various other system components. The installation of the mounting rails and panels happened at the same time as most of the electrical system installation - after 5 days the panels were installed and the majority of the battery system and Enphase control systems were installed as well. There were a couple delays due to a defective control board (which took a few weeks to obtain a replacement), but even while waiting for the replacement the SolTerra electrician and team finished up every part of the installation they could and scheduled the necessary inspections. By the beginning of September, we were all set and waiting for PSE to drop by to approve the installation and throw the switch to turn on the system. Throughout the installation, the electrician and crew were very communicative, keeping me updated on the progress they made each day and the timeline for inspections and any associated updates. I particularly appreciated the electrician's updates when the defective control board was discovered, and that he provided me with lots of details each day as he installed new components or made alterations. The end result was a beautiful system, from panel arrays to batteries to control systems and conduit - it was all very polished and showed professional engineering design and high-quality installation. After the system was operational, Kevin came to the house to provide a full walk-through of the system, components, and the related Enphase Enlighten app and its features. At the end of his visit, I had copies of all the plans, manuals, approvals, permits, and warranties, plus a complete understanding of my system and its indicators - I was one happy, informed customers. I was also really pleased that the SolTerra crew came right out when a small leak appeared from a vent that was jostled by the installation (the solar panel installation probably moved the old vent just a little bit). Kevin and Neil had a crew out the day after I contacted them and made certain that the vent and all nearby solar mount points were extra-sealed - the leak was completely resolved. I really, really appreciated their promptness and how they took the time to ensure there was no potential for leaks from the solar install - they stand by their products, crew, and customers completely. I would definitely recommend SolTerra to anybody considering a solar installation - they have a top-notch crew and use the best-in-class materials to provide a long-lasting, turn-key installation. I'll even be reaching out to them if we decide to expand out battery storage. :-)"

"Great install by qualified staff. Great follow up to fine tune the system to meet my needs. I am overall net zero including charging my EV. Highly recommend solar panels for Tacoma area and especially if you have TPU as service provider as they bank the excess hours produced in summer to use in the winter months."

"I had discussions with them regarding installing Solar Tube. They were courteous and provided a number of useful pointers to help me choose between installing a Skylight vs Solatube. The price quoted is reasonable and we are planning to have them install Solatubes for our house next month.

Solar Panels FAQs, answered by experts

Solar well pumps range from needing 200 watts of power to as much as 12,000 watts for heavy-duty pumps. Since the most common and cost-friendly solar panels are 100-watt panels, you’ll need between two and 12 panels. The average is between two and eight panels for standard pumps. Based on the average cost of solar panels ($1 to $1.50 per watt), you’d pay between $200 and $1,800 for your well pump solar panels—not including installation.

On average, a typical fridge uses 115 kWh per month. With eight hours of sunlight per day, a 100-watt solar panel can produce 30 kWh per month. This means you’ll need at least four dedicated panels to power the refrigerator with solar energy. Consult with a solar power specialist to get a more accurate estimate.

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.

You can start narrowing your search for a reputable solar company by finding local, regional, and national companies that service your area and maintain positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if the company has complaints filed against them. Next, contact the remaining candidates and ask about installation timelines, warranty coverage, and financing options. Choose a company that offers a labor warranty that lasts at least 10 years and prioritizes cash purchases and solar loans.

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.
