Factors that Affect Solar Panel Costs in Princeton

Even though the average cost of a solar system in Princeton is $9,220, your final cost may differ. There are many factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more important things to keep in mind.

Solar Equipment

When it comes to estimating the price of a solar panel system in Princeton, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home's energy consumption, which you can gauge by looking at past energy bills. Your total cost can increase by about $2,940 for each additional kilowatt you need. There are many different solar panel brands and the one you choose also changes the cost. Typically, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you're looking to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for solar panels out of pocket is out of reach, solar loans are an affordable option because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it'll take to pay off the loan.

Solar Panel Installation Company

The solar installer you go with to handle your switch to renewable energy can have an effect on your total costs. There are about 3 solar installation companies operating in Princeton, and each can charge varying amounts for labor and equipment. You may notice national solar installers that have lower prices because of their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

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

  • Warranty: A comprehensive, long-term warranty can help keep your solar panel system running for a long time and save you money on part replacement and repairs.
  • Contract: When reading through your solar company's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can check your installer's reputation is by reading reviews.
  • Solar Panel Brands: The model of solar panel you need to install plays a part in which installer you should opt for, since different companies have access to different panels.
