Factors that Affect Solar Panel Costs in West Windsor
There are a number of criteria that can affect your solar system 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
When it comes to estimating the price of a solar energy system in West Windsor, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can figure out by looking at past energy bills. Your overall cost can increase by around $3,530 for each additional kilowatt you need.The brand and kind of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a 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 greater savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Solar panels can save you money on power bills over time, but they can also be a significant investment. That’s why many West Windsor homeowners choose to finance their solar panel systems to offset upfront costs.When estimating 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 lower the total interest paid over time.
Solar Panel Installation Company
A final factor to consider when trying to figure out the cost of solar for your home or business in West Windsor is the company you choose to install your solar panel system. Similar to choosing a company to renovate your kitchen, for example, you’ll have no shortage of solar installers that provide a range of services at different price points.Larger national companies generally have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels
There are a large number of companies to choose from in West Windsor, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be challenging, so here are some tips to help you decide:
- Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you opt for.
- Warranty: A high-quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Contract: When reading over your solar installer’s contract, ask questions about any terms you’re not sure of and make sure you understand what happens in scenarios like a system part breaking or the company going out of business.
- Reputation: Make sure your solar panel installer has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like the EcoWatch team.

What solar power system size is right for my home?
The exact number of solar panels you need depends on your household energy needs and how much sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need.
