Factors that Affect Solar Panel Costs in Lambertville

Cost is often one of the most important factors for homeowners considering investing in solar. There are a few primary factors that will push your cost above or below the average in Lambertville: 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 price of solar panels in Lambertville, one of the most important 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 usage, which you can gauge by looking at past power bills. Your overall cost can increase by about $3,530 for each additional kilowatt you need.The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more in the long run on your electric bills. Additionally, extra products, like solar batteries, can bump up your total well above the Lambertville average.

Solar Financing Terms

Most solar installers in Lambertville offer solar loans, which reduce your upfront costs of installing a solar system.When considering your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

The solar installer you hire to handle your switch to green energy can play a part in your total costs. There are about 3 solar panel companies operating in Lambertville, and each can charge different amounts for labor and equipment.Some companies only sell high-efficiency and high-priced products — 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 choose a company that provides the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels

The solar panel company you choose will influence not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should consider, such as:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to get the job done well. Another way you can look into your installer’s reputation is by reading reviews.
  • Warranty: If you’re worried about the endurance of your solar panels, making sure your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Installation Process: When going solar, it’s important to maintain an open line of communication with your solar company. See to it that you understand how the installation process will go and the completion timeline.
  • Contract: Read the contract terms thoroughly to make sure you understand the cost breakdown, completion timeline rebates and warranties.
