Factors that Affect Solar Panel Costs in Maple Valley
While the average cost of a solar system in Maple Valley is $10,925, your final cost may be above or below the average. There are several factors that can have a significant impact on the cost of a residential solar panel installation. Below are some of the more crucial things to consider.
Solar Equipment
The size of the solar energy system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $3,590. The model of solar panels and equipment you want is another factor that will significantly impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Moreover, solar equipment is more than just the solar panels themselves. You’ll also need to make decisions about 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 falls within your budget.
Solar Financing Terms
Many homeowners find the average cost of solar in Maple Valley to be prohibitively costly, even if the investment pays off over time. Fortunately, almost every solar company in the area provides financing options. Solar loans remarkably decrease upfront costs in most cases, but they also lead to a higher cost over time because of interest.It’s wise to include 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
A final consideration when trying to evaluate the cost of solar for your home or business in Maple Valley is the company you hire to install your solar panel system. As with choosing a company to build a deck or pool, for instance, there are plenty of solar installers that offer a range of services for different budgets.Larger national companies typically have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
The solar installer you go with will impact not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should keep in mind, such as:
- Solar Panel Brands: The brand of solar panel you want to install plays a part in which installer you should choose, since different companies have different panels.
- Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
- Warranty: If you’re worried about the endurance of your solar system, ensuring your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
- 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’re not certain about some of the terms, such as what to do if a component breaks or malfunctions and what services you can expect from them.
