Factors that Affect Solar Panel Costs in Mendham

There are several factors that can determine your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.

Solar Equipment

The size of the solar system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by around $2,770. The brand and type of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

If paying for solar panels out of pocket is too expensive, solar loans are a solid option because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years. Though solar loans make adopting solar energy more accessible for Mendham homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The final major cost factor you should keep in mind is the installer you choose. Given the booming popularity of green energy solutions in Mendham, you'll have many options to choose from, but each comes at different price points for labor and equipment. Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and decide on the company that has the products, warranties and services you want and also fit into your budget.

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 pick the right company for you, here are some tips to keep in mind:

  • Installation Process: Get details from your solar company about the installation process and what to expect, including when the site survey will be done and how long it will take.
  • Contract: Before signing a contract with a solar company, be sure to look it over fully so you understand the terms. Also, ask questions if you're not sure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Reputation: Your solar installer should have a good reputation as a company and have demonstrated 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 satisfied reviews from previous customers.
  • Solar Panel Brands: Different companies have various brands and types of panels. If you know you want a specific brand, make sure the solar company you're considering has it.

Are solar panels free in Mendham?

How long do solar panels last in Mendham?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time.

You can replace them once you've had them for that long or you can keep using them at a lower efficiency.
