Factors that Affect Solar Panel Costs in South Rock Island
There are several criteria that can affect your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. For that reason, it’s important to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use.There are a lot of different solar panel brands and the one you pick also changes the cost. In general, the brands that offer higher efficiency tend to also be more expensive. In addition, 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
If paying for solar panels in cash is out of reach, solar loans are a solid choice because they lower your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you’re only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the original cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
The solar company you pick will play a role in your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.You may notice national solar installers that have lower prices because of 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.

What solar power system size is right for my home?
