Factors that Affect Solar Panel Costs in Duncanville
For many Duncanville homeowners, the decision to go solar rests on cost. However, the range of solar installation costs can be quite wide in Duncanville, with typical prices between $20,000 to $40,000. There are various factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to pay around $3,330 per kilowatt in Duncanville.There are a lot of different solar panel brands and the one you pick also changes the cost. Usually, the brands that have better efficiency tend to also be more expensive. Additionally, the type of equipment you’re looking to get can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Solar panels can save you money on utility bills over many years, but they can also be a big investment. That’s why many Duncanville homeowners opt to finance their solar panel systems to offset upfront costs.Though solar loans make switching to solar energy more accessible for Duncanville homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
Finally, the company you choose to install your solar panels can affect your pricing. Duncanville’s solar companies all have different labor costs and add varying upcharges to equipment. Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It’s best to do some research and decide on the company that offers the products, warranties and services you want and also fit into your budget.
