Factors that Affect Solar Panel Costs in Princeton

Cost is often one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that determine your overall cost in Princeton: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. For that reason, it’s crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use.There are a lot of different solar panel brands and the one you choose also affects the cost. Typically, the brands that are more efficient tend to also be more expensive. In addition, the type of equipment you’re looking to get 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

Most solar installers in Princeton offer solar loans, which reduce your upfront costs of installing a solar system.However, the interest on solar loans also increases your total costs, so it’s important to include that in your estimate as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.

Solar Panel Installation Company

The solar installer you go with to handle your switch to renewable energy can play a part in your total costs. There are about 3 solar installation companies operating in Princeton, and each can charge varying amounts for labor and equipment.Additionally, some companies in Princeton have more knowledge about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since picking a company can be difficult, we have some tips to help you, such as:

  • Reputation: Your solar installer should have a solid reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Warranty: A comprehensive, long-term warranty can help keep your solar panels running for years to come and save you money on repairs and maintenance.
  • Installation Process: Make sure you’re on the same page with the company with regard to how the installation process will go and what you need to do before your solar panels are installed, such as updating your electrical system or roof.
  • Contract: Though reading through a contract can be tedious, it’s important to do it fully so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
