Factors that Affect Solar Panel Costs in West Windsor

Cost is often one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that affect your total cost in West Windsor: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation require better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,770. The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag 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 more savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar installers in West Windsor offer solar loans, which reduce your upfront costs of installing solar panels. You'll have to consider the long-term cost of financing options, including the amount of interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in West Windsor is the company you hire to install your solar system. As with choosing a company to build a deck or pool, for example, there are plenty of solar installers that provide a range of services for different budgets. Additionally, some companies in West Windsor have more knowledge about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

Since the model of solar panels and the installer you choose has an impact on your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • 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 likely has a solid reputation and is qualified to get the job done well. Another way you can verify your installer's reputation is by reading reviews.
  • Contract: Though reading through a contract can be tedious, it's important to do it fully so you can make sure you understand what services your solar company will provide and the terms of the warranty.
  • Warranty: Each company may offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you choose.
