Factors that Affect Solar Panel Costs in Madison

There are a number of factors that can play into your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to spend around $3,530 per kilowatt in Madison.There are a lot of different solar panel brands and the one you choose also changes the cost. In general, the brands that have better efficiency tend to also cost more. Additionally, the type of equipment you want to install 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

For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are offered by most installers in Madison, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more affordable.However, the interest on solar loans also adds to your total costs, so it’s vital to keep that in mind as well. You can always lower the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

Finally, the company you choose to install your solar panels can influence the cost. Madison’s solar companies all have different labor costs and add varying upcharges to equipment. You may come across national solar installers that have lower prices because of their bigger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

There are numerous companies to choose from in Madison, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be tough, so here are some tips to help you decide:

  • Reputation: Your solar installer should have a solid reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.
  • Contract: It’s important to read through your solar installer’s contract closely to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panel system running smoothly and save you money on repairs and maintenance.

Is cost the most important thing to consider when buying solar panels?

The upfront cost is a key factor to consider, but whether it’s the most important for you depends on your goals for going solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.

How will installing solar panels impact how much my home is worth?

How many solar panels should I get to power my home?
