How to pay for solar panels in Tacoma, Washington

Purchasing solar panels is no small task. Here are a few ways you can pay for solar:

  • Cash purchase: This is the best choice if you can afford it. Paying in cash gives you the best long-term savings but requires a larger upfront investment, of course.
  • Solar loans: You can spread the cost over time with a loan, but be mindful of interest rates and loan terms.
  • Solar leases and PPAs: Power purchase agreements (PPA) and leases have lower upfront costs. However, you don't own the system, which means you save the least over time. There can also be complications if you want to sell your home.

What affects the cost of solar panels in Tacoma?

Several factors impact the final price of your solar installation:

  • System size: Larger systems cost more upfront but often yield greater long-term savings.
  • Panel type and efficiency: Monocrystalline panels are generally more efficient and expensive than polycrystalline or thin-film options.
  • Installation complexity: Roof type, shading, and site-specific challenges can increase installation costs. Permitting and inspection fees also factor in.
  • Additional considerations: Battery storage adds to the initial investment but provides backup power and greater energy independence. Labor and installation quality are also essential cost considerations.

How to save on Tacoma, WA solar panel costs

Getting the most bang for your buck is essential when investing in solar. Here are some strategies to save money:

  • Maximize the federal tax credit: Understand the eligibility requirements and claim the full 30% credit.
  • Shop around for quotes: Get quotes from multiple installers to compare pricing and services. Don't just focus on the lowest price; consider reputation, experience, and warranty.
  • Consider system size: Be careful of going overboard. A properly sized system will meet your energy needs without unnecessary costs. Analyze your energy usage to determine the optimal size.
  • Explore financing options: Compare loan interest rates and terms carefully. If considering a lease or PPA, understand the long-term implications and potential trade-offs. Cash purchases often offer the best long-term savings.
  • Negotiate with installers: Don't be afraid to negotiate on price. Inquire about any discounts or promotions they may offer.
  • Optimize your home's energy efficiency: Before going solar, improve your home's energy efficiency. This will reduce your overall energy consumption and potentially allow you to install a smaller, less expensive solar system. Simple steps like sealing air leaks and upgrading appliances can make a difference.
  • DIY (if possible and permitted): While professional installation is generally recommended, some homeowners may be able to handle certain tasks themselves (like site preparation). Check your local regulations and be honest about your abilities.
  • Ask about rebates and incentives: Many states, cities, and utility companies offer rebates, net metering, and other incentives. Check with your local utility and city/county for any available programs.
  • Time your installation: Sometimes, installers offer discounts during slower periods. Inquiring about seasonal promotions might yield savings.

Washington-specific solar considerations

  • Weather Impacts: Washington's weather really depends on where you are. Western parts of the state can be quite rainy and overcast, while eastern Washington enjoys plenty of sunshine. This variability means your system design may need to be tailored to your specific region.
  • Regulatory and Legal Considerations: The permitting process in Washington varies by region. It's important to review local building codes and any HOA guidelines to ensure your installation meets all necessary requirements.
