Factors that Affect Solar Panel Costs in Mendham
For many Mendham homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in Mendham, with typical prices between $20,000 to $40,000. There are numerous factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most important factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay about $3,530 per kilowatt in Mendham.Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Mendham, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Mendham to be too steep, even if the investment pays off over time. Fortunately, nearly every solar company in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in higher prices over time due to interest.Even though solar loans make going solar more accessible for Mendham homeowners, they can also raise 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
A final consideration when trying to estimate the cost of solar for your home or business in Mendham is the company you choose to install your solar system. Similar to choosing a company to build a deck or pool, for instance, you’ll have many options for solar installers that provide a range of services for different budgets.Some companies 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 cost more. It’s best to do some research and go with the company that offers the products, warranties and services you want and also fits within your budget.

EcoWatch's Mendham, NJ Solar Cost FAQs
What is the average cost of installing solar panels in Mendham?
This is a difficult question to answer exactly, because the cost depends on many factors. Broadly 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 other solar equipment or more efficient panels, or if you have above-average energy consumption. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.
Is cost the most important thing to consider when buying solar panels?
Cost is certainly one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.
Does Mendham have a net metering program?
The majority of states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system produces or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
How long do solar panels last in Mendham?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can choose to replace them after having them for that long or you can continue to use them at a lower efficiency.
