Factors that Affect Solar Panel Costs in Randolph
Cost is typically one of the most important factors for homeowners wanting to invest in solar. There are a few major factors that determine your overall cost in Randolph: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a few different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power production 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 $3,760.There are many 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. Additionally, the type of equipment you choose 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
For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are offered by most installers in Randolph, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more affordable.However, the interest on solar loans also adds to your total costs, so it’s crucial to consider that as well. You can always reduce the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
A final factor to consider when trying to estimate the cost of solar for your home or business in Randolph is the company you hire to install your solar panel system. Similar to choosing a company to build a deck or pool, for example, there are plenty of solar installers that offer a range of services for different budgets.Additionally, some companies in Randolph know more about local solar incentives and can help you take advantage 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 help you save more money in the long run.

EcoWatch's Randolph, IL Solar Cost FAQs
What is the average cost of installing solar panels in Randolph?
This is a tough question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $18,800 for a 5-kW system and $37,600 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy needs. Conversely, you can spend less if you go with a smaller solar panel system or less expensive solar panels.
What other factors should I consider in addition to cost when buying solar panels?
Cost is without a doubt one of the most important things to keep in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Can you sell solar power back to the grid in Randolph?
Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just offer you credit toward your future power bills.
How many solar panels should I get to power my home?
To figure out what solar panel system size you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
