Factors that Affect Solar Panel Costs in Denville

For many Denville homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in Denville, with typical prices between $20,000 to $40,000. There are a few factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power production need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $3,530.There are several different solar panel brands and the one you choose also changes the cost. In general, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you’re looking to get 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

Solar panels can save you money on power bills over many years, but they can also be a big investment. That’s why many Denville homeowners choose to finance their solar panel systems to make paying for solar more affordable.It’s wise to add the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it’ll take to pay off the loan.

Solar Panel Installation Company

A final factor to keep in mind when trying to evaluate the cost of solar for your home or business in Denville is the company you get to install your solar system. As with choosing a company to renovate your kitchen, for example, there’s no shortage of solar installers that provide a range of services for different budgets.You may notice national solar installers that have lower prices due to their bigger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels

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

  • Warranty: An all-inclusive, 25-year warranty can help keep your solar system running for a long time and save you money on repairs and maintenance.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you go with.
  • Installation Process: Get detailed information from your solar installer about the installation process and what to expect, including when the site survey will be done and what the project timeline is.
  • Reputation: Solar companies that have great reviews from their customers and that have been in business for many years in most cases provide high-quality solar panel installation and expertise.

EcoWatch's Denville, NJ Solar Cost FAQs

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

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 be more expensive if you want additional solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you choose a smaller solar panel system or less efficient solar panels.

Are solar panels free in Denville?

You can’t get solar panels for free in Denville. However, you may still be able to afford them on a lower budget. You can lease solar panels for a low upfront cost or, if you’d prefer to own your solar panels, you can finance them with a solar loan.

Can solar panels completely eradicate my power bills?

It is possible to erase your electricity bills with solar panels, but for most homeowners in Denville, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you’ll want to contact 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 should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
