Factors that Affect Solar Panel Costs in Decatur
For many Decatur homeowners, the decision to install a solar energy system comes down to cost. However, the range of solar installation costs can be quite wide in Decatur, with typical prices between $20,000 to $40,000. There are a few factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power generation need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,740.The kind of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more in the long run on your energy bills. In addition, add-on products, such as solar batteries, can bump up your total well above the Decatur average.
Solar Financing Terms
Solar panels can save you money on utility bills over time, but they can also be a big investment. That’s why many Decatur homeowners decide to finance their solar panel systems to make going solar more affordable.However, the interest on solar loans also increases your overall costs, so it’s important to include that in your estimate as well. You can always reduce the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
The solar installer you choose will affect your total cost to make the switch to solar power. Different companies will bill different amounts for the equipment and labor.You may notice national solar installers that have lower prices due to their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.
