Factors that Affect Solar Panel Costs in DeKalb
For many DeKalb homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in DeKalb, with typical prices between $20,000 to $40,000. There are a few factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. That’s why it’s crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use.The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive 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 increase the cost.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be a challenge. Solar loans are available from most installers in DeKalb, which can lower, or in some cases totally eliminate, your upfront costs to make solar more accessible.However, the interest on solar loans also adds to your total costs, so it’s crucial to consider that as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in DeKalb is the company you hire to install your solar system. As with choosing a company to renovate your kitchen, for instance, there’s no shortage of solar installers that offer a range of services for different budgets.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’re looking for and also is within your budget.
