Factors that Affect Solar Panel Costs in New Castle

Even though the average cost of solar panels in New Castle is $12,064, your actual cost may be above or below the average. There are many factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more important things to consider.

Solar Equipment

The size of the solar system you need for your home is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $2,580. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like New Castle, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited 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

For some homeowners, paying for solar panels out of pocket can be difficult. Solar loans are available from most installers in New Castle, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more accessible. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

Finally, the company you get to install your solar system can play a part in determining how much it costs. New Castle's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in New Castle are more knowledgeable 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 end up saving you more money in the long run.
