How To Choose a Solar Company

Putting solar panels on your roof could reduce your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

It's important to hire a licensed solar installer. This ensures that the work is done correctly using current installation best practices. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including solar contractors.

Read Customer Reviews

Check consumer review platforms like TrustPilot, the Better Business Bureau (BBB), and Google Reviews to see customer feedback about local solar companies. Detailed reviews can help you assess a company's dependability and level of service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

Get free, detailed quotes from 3–5 solar companies. The quotes should describe all costs and identify the exact solar parts included. Comparing several quotes can help you find the option that best fits your budget.

Ask About the Warranty

Quality solar installations should have comprehensive workmanship and performance warranties. The workmanship guarantee covers any installation issues such as poor alignment, poor wiring, or cracks in the panels. The performance warranty promises a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Solar power can help reduce your electricity costs long-term. When weighing solar panel's cost and value, be sure to factor in these considerations.

  • Look into utility rebates: Some energy providers may provide additional discounts to incentivize homeowners to install solar panels. Check the requirements and the rebate amounts offered by your local power company to determine your potential savings.
  • Compare system purchase options: Solar panels can be purchased upfront or financed through a lease or loan. Confirm important financing details such as payment schedule, fees, annual percentage rate (APR), and ownership implications when financing your solar system.
  • Research federal and state tax credits: A 26% federal solar tax credit on total system costs is available through 2032. Many states also have incentives. These credits provide substantial savings for solar customers.

Cost of Solar Installation in Crystal Lake

Crystal Lake homeowners typically spend about $17,168 on home solar systems after federal tax refunds.

Some homeowners prefer to lease their solar panels to reduce upfront costs.

Frequently Asked Questions About Solar in Crystal Lake, IL

A solar photovoltaic (PV) system can generate power to run any electric system or appliance in your home. A more specific example is installing a solar heating system for your water.

There are a number of benefits to home solar energy. You can raise your property values, save money, and qualify for tax benefits. With the right storage equipment, solar panels can also provide you with additional energy security and offer some protection from power outages.

It depends on where you live and what type of panels you're installing. Since there's a moderate amount of snowfall in Crystal Lake, your best time to install solar panels is in the spring and fall.

Generally speaking, your energy bills will significantly decrease after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Crystal Lake, the average amount someone can save is $904 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system when your payback period is done.

The maintenance you'll need to do will vary based on the type of solar panels you have. At a minimum, you should clean and inspect each panel four times a year. Your solar contractor might offer comprehensive plans where they'll do the maintenance for you.

Although solar energy is a great option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, a contractor might recommend other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still help the environment and could still qualify for distributed generation or other money-saving programs.

The best type of residential solar panel depends on your specific needs and goals. In most cases, monocrystalline solar panels are the most efficient for houses in Crystal Lake. However, if you're looking at a more frugal option, then you may want to consider thin-film or polycrystalline solar panels. When you're choosing a contractor, make sure to ask about the brand names and models of solar panels a contractor offers and the benefits and drawbacks of each.
