Factors that Affect Solar Panel Costs in King of Prussia
Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few major factors that affect your total cost in King of Prussia: 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
The size of the solar energy system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $3,550. Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like King of Prussia, where sunlight is relatively 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 King of Prussia to be too expensive, even if the investment pays off over time. Fortunately, nearly every solar installer in the area provides access to financing options. Solar loans remarkably decrease upfront costs in most cases, but they also lead to paying more over time because of interest.While solar loans make adopting solar energy more accessible for King of Prussia homeowners, they can also raise the total you pay for your system due to interest. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar installation company you select will play a role in your total cost to adopt solar energy. Different companies will charge different amounts for the equipment and labor.Additionally, some companies in King of Prussia know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
The company that does your system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since choosing a company can be a tough decision, we have some tips to help you, such as:

- Contract: Before signing a contract with a solar installer, be sure to read it through completely so you understand the terms. Also, ask questions if you’re not certain about some of the terms, such as what to do if a component breaks or malfunctions and what services you can expect from them.
- Solar Panel Brands: Each solar panel brand and model has varying levels of quality, longevity and efficiency. They will come at different costs as well. The company you choose impacts which solar panel brands you have access to.
- Reputation: Your solar installer should have a sound reputation as a company and have demonstrated expertise in the field. A couple of 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 satisfied reviews from previous customers.
