Methodology: How We Ranked the Best Solar Companies in Posen
EcoWatch's solar experts analyzed each solar company in Posen based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Posen
Below are some the criteria we examined specifically for Illinois solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Posen
We get that for many homeowners, the choice to invest in solar hinges on installation costs. The installation cost is just one important factor you should consider when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:
- System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
- Average daily sunlight: Since Posen gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which influences how much your solar panels can save you on your electricity bills.
- Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your utility bills, which can result in an average of $13,000 of savings over 20 years.
- Energy consumption: Installing a solar system may be too pricey an option for households that don't consume too much energy a month.
Due to the cost of solar panels being lower than before as well as several solar incentives, they are a sound investment for many homeowners.

Environmental Impact of Switching to Solar in Posen
One of the best reasons to embrace solar energy is to minimize your reliance on traditional energy sources like burning fossil fuels, which are damaging for the environment. But how much can switching to solar actually help the environment? An important thing to keep in mind is your overall carbon footprint. For example, if your commute is very long, your footprint may be larger, so adopting solar energy for your house can help offset that. In fact, if you make the switch to solar power, you could expect to reduce your carbon dioxide emissions by about 90 pounds each year. For homeowners who want to help the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.
