Factors that Affect Solar Panel Costs in Danville
There are many factors that can play into your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
One of the most important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to spend about $4,220 per kilowatt in Danville.There are several different solar panel brands and the one you choose also changes the cost. Usually, the brands that have better efficiency tend to also cost more. Plus, the type of equipment you’re looking to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Most solar companies in Danville have solar loans, which reduce the initial cost of installing a solar system.When trying to figure out your overall cost, you should also calculate the interest you’ll pay if you choose to go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.
Solar Panel Installation Company
A final factor to consider when trying to evaluate the cost of solar for your home or business in Danville is the company you choose to install your solar panel system. Similar to choosing a company to build a deck or pool, for example, there’s no shortage of solar installers that provide a range of services at different price points.You may see national solar installers that have lower prices due to their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels
The solar company you opt for will impact not only your total costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should take into account, such as:
- Installation Process: Get detailed information from your solar installer about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.
- Warranty: Companies typically offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Contract: It’s important to read your solar installer’s contract thoroughly to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to install your solar system. Another way you can research your installer’s reputation is by reading reviews.
EcoWatch's Danville, NH Solar Cost FAQs
