Why Go Solar in Illinois?

Although it may not have a wealth of sunshine, Illinois is a great place to invest in solar. With an average of 198 sunny days per year, Illinois is certainly below the American average of 205 sunny days annually.

Nonetheless, rapid improvements in photovoltaic technology have increased the efficiency of solar panels so that even cloudier and colder climates can sustain solar energy production.

Illinois is also an excellent state to purchase solar energy systems because of the existence of federal, state-level, and local financial and tax incentives designed to lessen the cost of buying and installing solar panels. Specifically, the government of Illinois has a Renewable Portfolio Standard, which encourages renewable energy production by mandating that a specific amount of electricity produced in the state be derived from renewable sources.

Finally, solar panels can dramatically increase your home’s value. According to Zillow, the average home experiences a 4.1% increase in value after adding a solar power system.

House Method’s Solar Companies Rating Methodology

At House Method, transparency and trust are our most important values for the reader. That’s why we took the time to create an objective rating system and score each solar energy company/service according to our methodology.

Our research team dug deep into the fine print of contracts, combed through more than one hundred customer reviews, and thoroughly investigated all of each solar energy company’s services, costs, and products. We’ve done the homework for you by researching nearly all of the solar energy companies on the market so you can have the information you need to make the best choice for your home.

We developed a formula to objectively determine the best solar energy companies and give each a score out of 100 based on the following criteria:

  • Plan Options (30): Do they provide a variety of plan options? We looked at the number of plans each solar energy company offered and the flexibility of adjusting the plan.
  • Services offered (20): How many services are offered in each plan? We looked at whether the company manufactures its own solar panels, whether it contracts out installation, and what additional products each company offers.
  • Trust (10): What do customers say after their solar panels are installed? Does this company offer a guarantee? We considered how satisfied customers are post-service if the company does what it says it will, BBB accreditation, and service guarantees.
  • Prices (10): How reasonable are the costs of the plan or service in comparison to the industry average? We compared the costs of each company to competitors that offer the same solar energy services.
  • Unique perks (10): Does the company offer discounts or special services such as financial incentives, rebates, or a useful mobile app? We looked for extras each company offers that set them apart from the competition.
  • Customer Service (10): How is the customer experience when contacting the company? We considered the speed of response, weekend/holiday availability, and ease of communication through phone calls, email, and online chat functions.
  • Nationwide availability (10): How many states does the company offer its services? Companies that operate nationally and in all zip codes are favored over those with limited availability.
