Factors that Affect Solar Panel Costs in Sammamish
There are several criteria that can influence your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power production use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,590.The brand of solar panels and equipment you want is another factor that will considerably affect costs. Solar panels that are more efficient, like monocrystalline panels, tend to be more expensive. Plus, solar equipment consists of more than just the solar panels themselves. You’ll also need to decide on 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 into a solar system that’s in your budget.
Solar Financing Terms
Solar panels can save you money on energy bills over time, but they can also be a significant investment. That’s why many Sammamish homeowners choose to finance their solar panel systems to make going solar more affordable.When estimating your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying more upfront can lower the total interest paid over time.
Solar Panel Installation Company
The solar company you hire to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar installation companies operating throughout Sammamish, and each can charge varying amounts for labor and equipment.Some companies only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It’s best to do some research and find a company that has the products, warranties and services you’re looking for and also fits within your budget.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because selecting a company can be a tough decision, we have some tips to help you, such as:
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. While there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of options before deciding.
- Contract: When reading over your solar installer’s contract, ask for clarification about any terms you’re not sure of and make sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
- Installation Process: One of the most important things to understand when adopting solar power is the installation process itself. Be sure to align on any details you need to know with your solar company, such as what permits you should secure and how long the project will take.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can check your installer’s reputation is by reading reviews.

Can you sell solar power back to the grid in Sammamish?
Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just offer you credit toward your future utility bills.
How often do you have to replace solar panels?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
