Factors that Affect Solar Panel Costs in Wilmington

Though the average cost of a solar system in Wilmington is $9,179, your final cost may be higher or lower than that. There are many factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more important things to take into consideration.

Solar Equipment

The size of the solar panel system you need for your household, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $2,940. The brand and type of equipment you choose for your solar system can increase or decrease 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 limited roof space or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Solar panels can save you money on energy bills over many years, but they can also be a big investment. That's why many Wilmington homeowners decide to finance their solar panel systems to make paying for solar more affordable. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you hire to install your solar panels can impact the cost. Wilmington's solar companies all have different labor costs and add varying upcharges to equipment. Companies that 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 cost more. It's best to do some research and decide on the company that provides the products, warranties and services you're looking for and also fits within your budget.

How to Save on Solar Panels

There are a lot of companies available in Wilmington, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be tough, so here are some tips to help you decide:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
  • Installation Process: Get details from your solar installer about the installation process and what to expect, including when the site survey will be done and how long it will take.
  • Contract: Review the contract terms closely to make sure you understand how much it will cost, project timeline rebates and warranties.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Even though there are many options for which brand of solar panel you can get, not every company will have the exact one you may want or need, so make sure you take a look at their list of offerings before making your decision.

EcoWatch's Wilmington, MA Solar Cost FAQs

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

This is a hard question to answer precisely, because the cost depends on a variety of factors. Generally speaking, it costs about $14,700 for a 5-kW system and $29,400 for a 10-kW system after the ITC is applied. It will be more expensive 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 want a smaller solar panel system or less efficient solar panels.

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

Leasing solar panels can be an appealing choice, because it usually 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 get the most savings.

Can solar panels significantly reduce my electricity bills?

Solar panels can potentially eliminate your electricity bills depending on where you're located and the efficiency of your system. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $1,156.94 per year.

How often do you have to replace solar panels?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
