Factors that Affect Solar Panel Costs in Windsor
Cost is often one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that affect your total cost in Windsor: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.
Solar Equipment
When it comes to estimating the cost of a solar panel system in Windsor, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home’s energy consumption, which you can figure out by looking at past energy bills. Your overall cost can increase by about $3,750 for each additional kilowatt you need.The brand and kind of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
If paying for a solar system in cash is out of reach, solar loans are an affordable choice because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years.When figuring out your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.
Solar Panel Installation Company
The solar installer you pick will influence your total cost to go solar. Different companies will bill different amounts for the equipment and labor.Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and decide on the company that has the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels
Since the type of solar panels and the installation company you choose greatly influences your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some things to keep in mind to help with your decision:
- Contract: It’s important to read through your solar installer’s contract thoroughly to understand what services they will provide, what the warranty covers and what you can expect about the cost.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. Even though there are many options for which type of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of offerings before deciding.
- Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to clarify any details you need to know with your solar installer, such as what permits you should secure and how long the project will take.
- Warranty: If you care about the longevity of your solar panel system, making sure your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
