Factors that Affect Solar Panel Costs in Warrenville

While the average cost of a solar system in Warrenville is $12,479, your final cost may be higher or lower than that. There are quite a few 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 installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household uses, the larger your system will likely need to be. You can expect to spend about $2,730 per kilowatt in Warrenville. The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof 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. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Solar panels can save you money on energy bills over many years, but they can also be a significant investment. That's why many Warrenville homeowners decide to finance their solar panel systems to offset upfront costs. When figuring out your overall cost, you should also calculate the interest you'll pay if you decide on a solar loan. Also, paying a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you choose to install your solar panels can affect your pricing. Warrenville's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Warrenville are more knowledgeable about local solar incentives and can help you make good use 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

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Contract: Look through the contract terms carefully to make sure you understand the cost breakdown, project timeline incentives and warranties.
  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you hire.
  • Reputation: Companies that have been operating for many years likely have a solid reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
  • Warranty: Warranties that provide coverage for panel repairs and maintenance over a couple decades are the gold standard in the business, and offering such a warranty is one sign of a quality company.

EcoWatch's Warrenville, IL Solar Cost FAQs

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

This is a tough question to answer exactly, because the cost depends on a few different 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. You can expect to pay more if you want extra solar equipment or higher quality panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.

Is it better to lease or buy solar panels in Warrenville?

Leasing solar panels can be an attractive choice, because it often 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 option if you want to maximize your savings.

Do solar panels increase the value of your home?

Solar panels can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Warrenville is currently $294,353, which means you can expect a value of about $12,068 more than houses without a solar system. The specific figures will vary, but most experts agree that installing solar panels in Warrenville is a worthwhile investment.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy usage and the amount of sunlight your roof gets. You can take a 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 install between 20 and 35 panels to account for their typical energy usage.
