Factors that Affect Solar Panel Costs in Fairfax

Cost is typically one of the most important factors for homeowners considering investing in solar. There are a few primary factors that affect your total cost in Fairfax: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That's why it's important to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use. The type of solar panels and equipment you want is another factor that will greatly influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Furthermore, 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 falls within your budget.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be challenging. Solar loans are provided by most installers in Fairfax, which can lower, or in some cases totally eliminate, your upfront costs to make solar more affordable. However, the interest on solar loans also increases your overall costs, so it's important to include that in your estimate as well. You can always lower the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

Lastly, the company you choose to install your solar panel system can impact your pricing. Fairfax's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Fairfax know more about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The company that does your system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because choosing a company can be a challenge, we have some tips to help you, such as:

  • Reputation: Make sure your solar system installer has a good reputation by verifying it has certifications and licenses, checking its number of years in business and reading reviews by past customers and solar experts like EcoWatch.
  • Contract: When reading over your solar installer's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and how much efficiency they need. Even though there are many options for which kind of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you take a look at their list of offerings before making your decision.
  • Warranty: A comprehensive, 25-year warranty can help keep your solar panel system running for years to come and save you money on part replacement and repairs.

EcoWatch's Fairfax, CA Solar Cost FAQs

What is the average cost of installing solar panels in Fairfax?

This is a difficult question to answer precisely, because the cost depends on many factors. Broadly speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or more efficient panels, or if you have above-average energy usage. On the other hand, you can spend less if you choose a smaller solar panel system or less expensive solar panels.

Should I lease or buy solar panels in Fairfax?

Leasing solar panels can be an option if you can't pay upfront or secure a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your property 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.

Is making the switch to solar worth it?

Solar panels can be a great investment for lots of homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your electricity bills are already fairly low, solar panels might not be for you.

How many solar panels do I need to power my home?

To figure out what solar panel system size you need, you should find out how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
