Benefits of Solar Energy

Solar energy has several advantages that will enhance your home for years to come.

  • Reduced carbon footprint: The sun is the universe's most abundant clean energy source, meaning you can minimize or conquer your home's dependence on non-renewable sources.
  • Better energy independence: Photovoltaic systems with energy storage work through blackouts and emergencies, and you won't have to rely on the electrical grid for your safety and well-being.
  • Lowered energy bills: You can dodge the expensive cost of grid-tied power by generating some electricity right where you use it.

How To Choose the Best Solar Company in Tacoma

The price and performance of solar panels often depend on the provider that mounted them. Here are some important factors to bear in mind while shopping for a solar provider.

Licensing and Training

Solar contractors in Washington must hold an electrical contractors' license from the Department of Labor and Industries. In some situations, the department may also conduct permit inspections to confirm compliance and the integrity and viability of a contractor's job. Solar companies can also pursue certifications from trade groups and standards organizations. The most recognized ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Tacoma

The style of solar panels you choose decides how much power you can produce. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't meant for large home installations, but they're excellent for small projects like sheds and RVs.

Additional components, such as battery storage and electric vehicle (EV) chargers, will add to your overall costs. However, they might make your solar system more efficient and convenient to use. Not all solar providers provide these add-ons, so look for a company that sells them if it's a priority for you.

You can plan to spend about $17,950 on average for a five-kilowatt solar energy system in Tacoma. Use the table in this section to get an idea of how much Tacoma solar companies might quote for your specific system.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,151
Solar Polycrystalline$898
Solar Battery$737
Solar Home EV Charger$2,763

Financing Solar Energy in Tacoma

There are various ways to pay for a solar energy system, and the right one will lower your costs. A few of the most common options include leases, cash payments, power purchase agreements (PPAs), and loans. We suggest making a cash payment or securing a solar loan for the best return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also have full ownership of your system and can apply for solar incentives to cut your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases allow you to pay a monthly fee to rent your panels, while a power purchase agreement lets you pay a fluctuating rate based on only the energy you use. We generally don't recommend these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be appropriate in particular circumstances. We advise working with a provider that offers multiple financing options. Ask each representative about what's available, and secure more than one estimate for the best odds of staying within your spending limits.

The table below lists the average payback periods for different capacities of solar systems in Tacoma.

You are eligible for a 26% federal tax credit for new solar power systems until the year 2032. City and state officials and utility companies might also offer rebates, discounts, and unique financing solutions that could save you more.
