Factors that Affect Solar Panel Costs in Williams

Even though the average cost of a solar system in Williams is $11,944, your final cost may differ. There are quite a few factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more important things to take into consideration.

Solar Equipment

The size of the solar energy system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $2,730. The brand and type of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a 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 limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

If paying for a solar system in cash is difficult, solar loans are a solid choice because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in Williams is the company you choose to install your solar system. As with choosing a company to install new cabinets, for example, there are plenty of solar installers that provide a range of services for different budgets. Additionally, some companies in Williams know more about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

Since the kind of solar panels and the installer you choose has an impact on your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Solar Panel Brands: The kind of solar panel you need to install plays a part in which company you should choose, since different companies offer different panels.
  • Contract: It's important to read through your solar installer's contract thoroughly to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar system running smoothly and save you money on part replacement and repairs.
  • Installation Process: An important thing to understand when adopting solar power is the installation process itself. Be sure to align on any details you should know with your solar company, such as what permits you should secure and how long the project will take.

EcoWatch's Williams, IL Solar Cost FAQs

What is the average cost of installing solar panels in Williams?

This is a difficult question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or more efficient panels, or if you have above-average energy consumption. Conversely, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.

Is it better to lease or buy solar panels in Williams?

Leasing solar panels can be an appealing choice, because it often comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any incentives and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Can solar panels completely eradicate my power bills?

It is possible to erase your electricity bills with solar panels, but for most homeowners in Williams, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you'll want to contact a local solar installer to see how many panels can fit on your roof.

What solar power system size is right for 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 house will need 20 to 35 panels.
