"Nick Richardson was awesome to work with, for that matter, the whole of SolTerra was great. Nick showed me an overview of what solar power is capable of and then tailored the system to my exact needs. All said and done, I am producing power every day , some days its less than I consume, but on overage ( 2 months and counting) I have over produced and end up with a PUD credit. This company is really easy to work with, and enlightened me to the options of free energy. If you are on the fence about solar power, come on over, you'll be surprised at what you've been missing. Lastly my experience seems to be the norm, I'm super happy and wish that I`d done it sooner, looking at others reviews of SolTerra, I now understand why this company is so highly rated!"

"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."

Solar Panels questions, answered by experts

For most U.S. homeowners, switching to solar energy is an excellent investment. A properly sized solar array can significantly reduce your electric bill, saving money on utilities every month. Most homeowners enjoy savings that cover the cost of their solar systems within 12 years and then turn a profit. Additionally, federal and state tax incentives are available that help make solar an even better and more profitable investment.

The actual time it takes to construct the solar farm is relatively short, taking between 2 and 4 months on average. That timeline is dependent on site conditions, crew size, and the overall size of the solar farm.

However, the time it takes to get the ball rolling is significantly longer, ranging from 3 to 5 years. With a project of this scale, you’ll need to obtain all of the proper permits and approvals to start breaking ground, and depending on your location, that could be an extended process.

There are a few great questions to ask a solar contractor or inspector when you speak to them. You’ll probably want to find out about the energy yield and efficiency of your array, ensuring the actual output matches the amount you calculated when installing the array in the first place. It’s also a good idea to find out about any damage or wear and tear on the array and to inquire about how soon you need to make repairs or replacements to essential components.

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

Yes, it is possible to install solar panels on a tar and gravel roof, but it is not the ideal roofing material for a solar installation. The process requires roof penetrations to install the solar racking system. While installers will seal these penetrations, they still increase the risk of leaks. This risk is higher on tar and gravel roofs, which are often flat. Flat roofs are more prone to leaks than sloped roofs because they can pool water during heavy rain and hold snow for longer periods, exposing the roof to more moisture.
