Factors that Affect Solar Panel Costs in Napa

Cost is typically one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that determine your overall cost in Napa: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to spend around $2,730 per kilowatt in Napa. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Napa, where sunlight is abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a significant investment. That's why many Napa homeowners decide to finance their solar panel systems to make paying for solar more affordable. When figuring out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more upfront can lower the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar system can influence the cost. Napa's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Napa are more knowledgeable about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. 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 available to you, and it will also have an impact on your total cost. Since choosing a company can be a tough decision, we have some tips to help you, such as:

  • Contract: Before you sign a contract with a solar installer, make sure to look it over completely so you understand the terms. Also, ask questions if you're not sure about some of the terms, such as what to do if a part breaks or malfunctions and if there are any guarantees about energy production.
  • Reputation: Make sure your solar installer has a good reputation by verifying it has certifications and licenses, checking its work history and reading reviews by previous customers and solar experts like EcoWatch.
  • Solar Panel Brands: The model of solar panel you want to install plays a part in which installer you should opt for, since different companies have access to different panels.
  • Installation Process: Get detailed information from your solar installer about the installation process and what to expect, such as when the site survey will be done and how long it will take.

EcoWatch's Napa, CA Solar Cost FAQs

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

This is a tough question to answer exactly, because the cost depends on a variety of 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. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, 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 Napa?

Leasing solar panels can be an attractive choice, as it commonly comes with low or $0 upfront payments. The drawback 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 incentives and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Do solar panels increase the value of your home?

Installing solar panels on your home can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Napa is currently $643,975, so you can expect about a value of about $26,403 more than houses without a solar system. The specific figures will vary, but most experts agree that installing solar panels in Napa is a fruitful investment.

How many solar panels should I get to power my home?

The exact number of solar panels you need depends on your household energy usage and how much sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to cover their typical energy usage.
