Factors that Affect Solar Panel Costs in Mendham

Cost is typically one of the most important factors for homeowners wanting to invest in solar. There are a few major factors that determine your overall cost in Mendham: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

When it comes to estimating the cost of a solar energy system in Mendham, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home's energy usage, which you can determine by looking at past electricity bills. Your total cost can increase by around $2,770 for each additional kilowatt you need. The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more over time on your power bills. Additionally, add-on products, like solar batteries, can bring your total well above the Mendham average.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That's why many Mendham homeowners opt to finance their solar panel systems to make paying for solar more affordable. Although solar loans make switching to solar energy more accessible for Mendham homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Mendham is the company you get to install your solar panel system. As with choosing a company to install new cabinets, for example, there's no shortage of solar installers that provide a range of services at different costs. You may notice national solar installers that have lower prices because of their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

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.

The average cost of solar panels in Mendham is about $13,850 for a 5-kW system and $27,700 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the model of solar panels you want, what size system you need and how much energy you use.

Are solar panels free in Mendham?

Solar panels aren't free in Mendham, but there are some options that can make getting them more viable, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can help lower the cost.

Is it worth going solar in Mendham?

Solar panels can be a beneficial investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your electricity bills are already reasonably low, solar panels might not be for you.

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. What this means is how much energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can keep using them at a lower efficiency.
