Factors that Affect Solar Panel Costs in Green Brook

Though the average cost of a solar system in Green Brook is $11,701, your final cost may be above or below the average. There are quite a few factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more important things to consider.

Solar Equipment

The size of the solar system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by around $3,530. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Green Brook, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

If paying for solar panels out of pocket is too expensive, solar loans are an affordable route because they reduce your upfront costs and let you pay for your system over five to seven years on average.Though solar loans make going solar more accessible for Green Brook homeowners, they can also add to the total you pay for your system due to interest. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar installer you hire to handle your switch to clean energy can have an effect on your total costs. There are about 3 solar panel companies in Green Brook, and each can charge varying amounts for labor and equipment.Larger national companies generally have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar company you opt for will influence not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should take into account, including:

  • Contract: It’s important to look over your solar installer’s contract fully to understand what services they will provide, what the warranty covers and what expectations you should have about the cost.
  • Installation Process: Get details from your solar company about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panels running smoothly and save you money on part replacement and repairs.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean 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.

EcoWatch's Green Brook, NJ Solar Cost FAQs

How much does it cost to install solar panels in Green Brook?

This is a hard question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $17,650 for a 5-kW system and $35,300 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. Conversely, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.

Is cost the most important consideration when buying solar panels?

Cost is a very important factor to consider, but whether it’s the most important for you depends on your goals for going solar. In cities where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Can solar panels eliminate my power bills?

It is possible to eliminate your electricity bills with solar panels, but for most homeowners throughout Green Brook, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you’ll want to check with a local solar installer to see how many panels can fit on your roof.

How many solar panels should I get to power my home?

To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
