"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 am super happy with my experience with Exact Electric. I found the team responsive and knowledgeable. Erin was our onsite contact and she took every opportunity she could to try to be creative in getting our wiring in without damaging the walls. The team worked hard to be accommodating as it was a large project. The new lighting they installed met our needs and we couldn't be more thrilled with the results."

"Ecostar Remodeling completely transformed our outdated living room into a bright and modern space. They opened up the layout, replaced the old flooring, and installed custom shelving that ties the entire room together. What impressed us was how collaborative they were, they truly listened to our vision but also gave us expert advice that improved on our original ideas. Their designers made smart recommendations that balanced aesthetics with functionality, like adding recessed lighting that completely changed the feel of the room. The crew was respectful and professional throughout, and they completed the project on time. Now, the living room feels inviting, comfortable, and perfect for both family time and hosting guests."

FAQs for solar panel installation projects in Seattle, WA

If you experience frequent power outages, want to become more energy independent, or aim to reduce your reliance on the grid, investing in a solar battery system can be worthwhile. With a solar battery, you'll have backup power day or night, even if the local grid fails. However, to power larger appliances or ensure you have energy for longer periods, you'll need to invest in multiple batteries. While the upfront cost is higher, many homeowners find the added peace of mind to be well worth the investment.

Solar battery storage capacity is measured in kilowatt-hours, which directly indicates the amount of energy the battery can store. This measurement determines how long essential appliances will continue operating during an outage. A clear understanding of capacity helps in planning the overall system size to ensure effective backup power and to maintain optimal performance even as the battery ages.

Determining the correct size for your solar battery system requires evaluating your monthly energy usage. Start by reviewing your utility bills to identify your average consumption, and then match the battery’s kilowatt-hour rating to cover essential loads. Consulting with a solar professional ensures that the system is sized to deliver continuous backup power, meeting both immediate and future energy needs.

A solar battery's lifespan ranges from five to 15 years, and its durability is affected by battery quality, charging frequency, and environmental conditions. Regular maintenance and proper usage are key to maximizing longevity. Monitoring your system, following manufacturer guidelines, and scheduling routine inspections all help ensure that your battery performs reliably throughout its service life.
