Factors that Affect Solar Panel Costs in Mountlake Terrace

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

Solar Equipment

When it comes to estimating the cost of solar panels in Mountlake Terrace, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily based on your home’s energy consumption, which you can gauge by looking at past power bills. Your total cost can increase by around $3,590 for each additional kilowatt you need.The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Mountlake Terrace to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar company in the area provides financing options. Solar loans substantially decrease upfront costs for most homeowners, but they also lead to paying more over time because of interest.You’ll have to consider the long-term cost of loans, including the total interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar panels can impact how much it costs. Mountlake Terrace’s solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Mountlake Terrace are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The solar installer you opt for will impact 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:

  • Solar Panel Brands: Different companies will offer various brands and models of panels. If you prefer a specific brand, make sure the solar panel company you’re considering has it.
  • Reputation: Long-running companies likely have a good reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer service, such as part repairs and replacements.
  • Installation Process: Make sure you’re on the same page with the company regarding how the installation process will go and what needs to be done before your solar panel system is installed, such as repairing your electrical system or roof.
  • Contract: Even though reading through a contract can be tedious, it’s important to do it fully so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.

EcoWatch's Mountlake Terrace, WA Solar Cost FAQs

How much does it cost to install solar panels in Mountlake Terrace?

This is a hard question to answer exactly, because the cost depends on a variety of factors. Broadly speaking, it costs about $17,950 for a 5-kW system and $35,900 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or more efficient panels, or if you have above-average energy consumption. On the other hand, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Is it better to lease or buy solar panels in Mountlake Terrace?

Leasing solar panels can be an attractive choice, as it commonly comes with low or $0 upfront payments. The downside is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any tax rebates and credits and your home value won’t increase. Buying solar panels is a better option if you want to get the most savings.

How much can I save on power bills after switching to solar?

It is possible to erase your electricity bills with solar panels, but for most homeowners in Mountlake Terrace, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you’ll want to check with a local solar installer to see how many panels can fit on your roof.

What solar power system size is right for my home?

To figure out how many solar panels you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
