Factors that Affect Solar Panel Costs in Denville

For many Denville homeowners, the decision to go solar depends on 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 various 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 a variety of factors. One of the notable factors is the system size. Solar power systems with greater efficiency or power generation 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 $2,770. There are many different solar panel brands and the one you pick also affects the cost. Usually, the brands that offer higher efficiency tend to also cost more. Additionally, the type of equipment you choose can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system out of pocket is difficult, solar loans are a popular route because they reduce your upfront costs and let you pay for your system over five to seven years on average. When figuring out your overall cost, you should also calculate the interest you'll pay if you opt for a solar loan. Also, paying more upfront can lower the total interest paid over time.

Solar Panel Installation Company

Finally, the company you hire to install your solar panels can play a part in determining your pricing. Denville's solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since selecting a company can be difficult, we have some tips to help you, such as:

  • Contract: It's important to read through your solar installer's contract fully to understand what services they will provide, what the warranty covers and what you can expect about your solar system's energy production.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and how much efficiency they need. While there are many options for which type of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you ask for their list of offerings before making your decision.
  • 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 certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panels running for a long time and save you money on repairs and maintenance.
