Factors that Affect Solar Panel Costs in Westminster

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

Solar Equipment

When it comes to estimating the cost of a solar panel system in Westminster, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy consumption, which you can gauge by looking at past power bills. Your total cost can increase by about $2,730 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Westminster, where sunlight is abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited 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

Many homeowners find the average cost of solar in Westminster to be prohibitively expensive, even if the investment pays off over time. Thankfully, almost every solar company in the area provides access to financing options. Solar loans remarkably decrease upfront costs in most cases, but they also result in paying more over time because of interest. Though solar loans make switching to solar energy more accessible for Westminster homeowners, they can also increase the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar company you opt for to handle your switch to solar energy can play a role in your total costs. There are about 3 solar panel companies in Westminster, and each can charge different amounts for labor and equipment. Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and find a company that provides 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 system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because picking a company can be a challenge, we have some tips to help you, such as:

  • 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 past customers and solar experts like EcoWatch.
  • Solar Panel Brands: Different companies will have various brands and kinds of panels. If you want a specific brand, make sure the solar installer you're considering has it.
  • Contract: Read the contract terms thoroughly to make sure you understand the cost breakdown, project completion timeline rebates and warranties.
  • Warranty: Warranties that provide coverage for defective panels and repairs over a couple decades are the best you can get in the business, and offering that kind of warranty is one indication of a good company.

EcoWatch's Westminster, CA Solar Cost FAQs

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

This is a difficult question to answer precisely, because the cost depends on a few different 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 higher quality panels, or if you have higher-than-average energy needs. On the other hand, you can spend less if you want a smaller solar panel system or less efficient solar panels.

Is cost the most important thing to consider when buying solar panels?

Cost is a crucial factor to consider, but whether it's the most important for you depends on your goals for going solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to take into account are the quality and durability of your solar panels.

Is it worth going solar in Westminster?

Solar panels can be a fruitful 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 pretty low, solar panels might not be for you.

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

To figure out how many solar panels 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.
