Factors that Affect Solar Panel Costs in South Elgin
While the average cost of a solar system in South Elgin is $17,188, your actual cost may be above or below the average. There are many factors that can have a significant impact on the cost of a residential solar panel installation. Below are some of the more important things to keep in mind.
Solar Equipment
When it comes to estimating the price of a solar energy system in South Elgin, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy consumption, which you can figure out by looking at past electricity bills. Your overall cost can increase by about $3,760 for each additional kilowatt you need.Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like South Elgin, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are available from most installers in South Elgin, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable.When figuring out your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying a higher down payment can lower the total interest paid over time.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in South Elgin is the company you hire to install your PV system. As with choosing a company to build a deck or pool, for instance, you’ll have many options for solar installers that offer a range of services at different price points.Some companies 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 come at a higher cost. It’s best to do some research and find a company that has the products, warranties and services you’re looking for and also is within your budget.

How to Save on Solar Panels
Since the type of solar panels and the installer you choose has an impact on your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some things to keep in mind to help with your decision:
- Warranty: Companies typically offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. Even though there are many options for which model of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to ask for their list of options before deciding.
- Contract: Review the contract terms carefully to make sure you understand the cost breakdown, completion timeline incentives and warranties.
- Reputation: Companies that have been operating for many years likely have a good reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer service, such as part repairs and replacements.
