Factors that Affect Solar Panel Costs in Lewisville
The cost of installing a solar system in Lewisville can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The biggest one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar company you choose.
Solar Equipment
One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay around $3,330 per kilowatt in Lewisville.There are many different solar panel brands and the one you choose also affects the cost. Typically, the brands that have better efficiency tend to also be more expensive. Plus, the type of equipment you’re looking to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Solar panels can save you money on power bills over time, but they can also be a big investment. That’s why many Lewisville homeowners opt to finance their solar panel systems to offset upfront costs.It’s a good idea to include the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it’ll take to pay back the loan.
Solar Panel Installation Company
The final key cost factor you should consider is the installer you choose. Given the massive popularity of sustainable energy solutions in Lewisville, you’ll have many options to choose from, but each comes at different price points for labor and 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 offers the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels
There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you decide on the right company for you, here are some tips to keep in mind:
- Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you choose.
- Reputation: Your solar installer should have a good reputation as a company and have verifiable expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
- Contract: When reading through your solar company’s contract, ask questions about any terms you’re not sure of and be sure you understand what happens in scenarios like a system component breaking or if the company goes out of business.
- Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to align on any details you should know with your solar installer, such as what permits you should secure and how long the project will take.
EcoWatch's Lewisville, TX Solar Cost FAQs
How much does it cost to install solar panels in Lewisville?
This is a hard question to answer precisely, because the cost depends on many factors. Broadly speaking, it costs about $16,650 for a 5-kW system and $33,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you go with a smaller solar panel system or less expensive solar panels.
Should I lease or buy solar panels in Lewisville?
Leasing solar panels can be an option if you can’t afford to pay upfront or secure a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.
Does Lewisville have a net metering program?
The majority of states offer net metering programs of some kind. Through these, you can either be compensated for the extra power your system generates or or receive credits to put toward future electricity bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
How often do you have to replace solar panels?
On average, solar panels can last 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 amount of energy production.
