Factors that Affect Solar Panel Costs in Iselin

There are a number of criteria that can affect your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to spend about $3,530 per kilowatt in Iselin.There are a lot of different solar panel brands and the one you pick also changes the cost. Generally, the brands that offer higher efficiency tend to also be more expensive. Additionally, the type of equipment you want to install can affect your total cost. If you only 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 choice because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.However, the interest on solar loans also increases your all-in costs, so it’s important to consider that as well. You can always reduce the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

The solar company you pick will impact your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.Larger national companies usually have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

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

  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you choose.
  • Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
  • Warranty: Companies typically offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Contract: Read the contract terms thoroughly to make sure you understand how much it will cost, project timeline incentives and warranties.

EcoWatch's Iselin, NJ Solar Cost FAQs

How much does it cost to install solar panels in Iselin?

This is a tough question to answer precisely, because the cost depends on many 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 cost more if you want extra solar equipment or more efficient panels, or if you have above-average energy usage. On the other hand, you can spend less if you want a smaller solar panel system or less expensive solar panels.

Should I lease or buy solar panels in Iselin?

Leasing solar panels can be an option if you can’t pay upfront or secure a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.

Can solar panels completely eradicate my electricity bills?

It is possible to erase your electricity bills with solar panels, but for most homeowners throughout Iselin, that will require at least a 10-kW system. Not all homes will have the roof space for 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 often do you have to replace solar panels?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
