Factors that Affect Solar Panel Costs in Princeton
There are a number of factors that can influence 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 panels.
Solar Equipment
One of the most significant 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 pay around $3,330 per kilowatt in Princeton.Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Princeton, where sunlight is abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Princeton to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar company in the area provides financing options. Solar loans drastically decrease upfront costs in most cases, but they also lead to paying more over time because of interest.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you’re only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs considerably.
Solar Panel Installation Company
A final factor to consider when trying to evaluate the cost of solar for your home or business in Princeton is the company you hire to install your PV system. Similar to choosing a company to install new cabinets, for example, you’ll have many options for solar installers that provide a range of services for different budgets.Some companies only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and choose a company that offers the products, warranties and services you want and also fit into your budget.

EcoWatch's Princeton, TX Solar Cost FAQs
How much does it cost to install solar panels in Princeton?
The average cost of solar panels in Princeton is about $16,650 for a 5-kW system and $33,300 for a 10-kW system before the ITC, but the real cost will depend on stuff like the type of solar panels you want, what size system you need and how much energy you use.
Should I lease or buy solar panels in Princeton?
Leasing solar panels can be an option if you can’t afford to pay upfront or secure a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.
Is it worth going solar in Princeton?
Solar panels can be a great investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your energy bills are already reasonably low, solar panels might not be for you.
How many solar panels should I get to power my home?
To figure out what solar panel system size you need, you should find out how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
