Factors that Affect Solar Panel Costs in Washington

The cost of installing a solar system in Washington can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The most significant one is the size of the system your home needs, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment Size

System size is one of the largest factors that affects the overall cost of going solar. That's why it's crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your typical energy use. The type of solar panels and equipment you choose is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more pricey. Moreover, solar equipment goes beyond just the solar panels themselves. You'll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking for a solar system that's in your budget.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be difficult. Solar loans are offered by most installers in Washington, which can reduce, or in some cases completely eliminate, your upfront costs to make solar more affordable. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

The solar company you opt for to handle your switch to solar energy can play a role in your total costs. There are about 3 solar installation companies in Washington, and each can charge varying amounts for labor and equipment. You may see national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels

The solar company you choose will influence not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should consider, including:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can research your installer's reputation is by reading reviews.
  • Warranty: Warranties that cover replacement parts and repairs over around 25 years are the gold standard in the business, and offering such a warranty is one mark of a good company.
  • Contract: Before signing a contract with a solar company, be sure to look it over carefully so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what the warranty covers and what services you can expect from them.
  • Solar Panel Brands: The kind of solar panel you want plays a role in which company you should go with, since different companies provide different panels.

EcoWatch's Washington, NJ Solar Cost FAQs

How much does it cost to install solar panels in Washington?

This is a tough question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $13,850 for a 5-kW system and $27,700 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you want a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Washington?

Leasing solar panels can be an option if you are unable to pay upfront or secure a solar loan, but since you don't own the system, you can't take advantage of many solar incentives. Also your home value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.

Does Washington have a net metering program?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just give you credit toward your future energy bills.

How long do solar panels last in Washington?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
