Factors that Affect Solar Panel Costs in Neptune

For many Neptune homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in Neptune, with typical prices between $20,000 to $40,000. There are various factors that significantly influence the price you’ll pay, which we'll go over below.

Solar Equipment

The size of the solar system you need to offset your energy usage, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $3,530. The kind of solar panels and equipment you get is another factor that will considerably affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more expensive. Plus, solar equipment consists of more than just the solar panels themselves. You’ll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that falls within your budget.

Solar Financing Terms

For some homeowners, paying for solar panels out of pocket can be difficult. Solar loans are available from most installers in Neptune, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more accessible.You’ll have to consider the long-term cost of loans, including the total interest you’ll pay over the length of the loan. If you’re only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the original cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

Lastly, the company you choose to install your solar panel system can impact your pricing. Neptune’s solar companies all have different labor costs and add varying upcharges to equipment. The company’s size sometimes plays the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels

There are a lot of companies available in Neptune, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be challenging, so here are some tips to help you decide:

  • Warranty: Many companies offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Installation Process: When going solar, it’s necessary to keep an open line of communication with your solar company. See to it that you understand how the installation process works and the completion timeline.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to do the job well. Another way you can verify your installer’s reputation is by reading reviews.
  • Contract: It’s important to read your solar installer’s contract carefully to understand what services they will provide, what the warranty covers and what you can expect about your solar system’s energy production.
