Factors that Affect Solar Panel Costs in Willowbrook

Although the average cost of a solar system in Willowbrook is $5,446, your final cost may be above or below the average. There are many factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more crucial things to keep in mind.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of adopting solar energy 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 pay around $2,730 per kilowatt in Willowbrook. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Willowbrook, 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

Most solar installers in Willowbrook provide solar loans, which reduce your upfront costs of installing solar. However, the interest on solar loans also adds to your all-in costs, so it's crucial to keep that in mind as well. You can always bring down the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

The solar company you hire to handle your switch to sustainable energy can play a role in your total costs. There are about 3 solar installation companies in Willowbrook, and each can charge different amounts for labor and equipment. Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the type of solar panels and the company you choose has an impact on your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • 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.
  • Installation Process: Homeowners should make sure they understand how exactly the installation process will go, as well as important factors like the completion timeline.
  • Contract: Review the contract terms closely to make sure you understand the cost breakdown, project completion timeline rebates and warranties.
  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, durability and energy efficiency. They will come at different prices as well. The company you choose has an impact on which solar panel brands you have access to.

EcoWatch's Willowbrook, CA Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on many factors. Generally 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 cost more if you want other solar equipment or more efficient panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

What other factors should I consider in addition to cost when buying solar panels?

Cost is certainly one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

Is it worth going solar in Willowbrook?

Solar panels can be a good investment for most 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 reasonably low, solar panels might not be for you.

How long do solar panels last in Willowbrook?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is how much energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency.
