Benefits of Solar Energy

Solar energy offers multiple perks. Let's look at a few of them.

  • Lower utility costs: Sourcing some or all of your own power will save you money on your electric bills long-term.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on fossil fuels, which release greenhouse gases that damage the environment.
  • Better energy independence: Adding a battery backup lets you have trustworthy energy during grid outages and storms.

How To Choose the Best Solar Company in Quincy

The more informed your company investigation is, the better your solar panels will ultimately perform. Consider all of these criteria in your business search.

Licensing and Training

In Illinois, the state Commerce Commission issues licenses to distributed generation energy contractors, including solar contractors. Solar providers can also obtain certifications from standards organizations and trade groups. The most recognized ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Quincy

Your photovoltaic panels' type will influence how much power you can produce. Monocrystalline panels cost the most but perform the best. Polycrystalline panels generate less, but they're a great traditional option for low budgets. Thin-film panels have a low cost and are excellent for non-traditional roofs, but aren't recommended for large home installations.

Additional accessories, such as electric vehicle (EV) chargers and battery storage, will add to your overall costs. However, they might make your solar system more efficient and convenient to use. Not all solar companies include these extras, so look for a provider that sells them if it's important for you.

Most Quincy homeowners select solar systems designed for five kilowatts (kW) of electrical capacity. These systems cost about $18,800 to install, considering both materials and labor. You can see more specific cost information in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,178
Solar Polycrystalline $919
Thin-Film $537
Solar Battery $754
Solar Home EV Charger $2,828

Financing Solar Energy in Quincy

Choosing the right financing option will influence your overall solar system cost and possible savings. Common payment options include cash payments, leases, loans, and power purchase agreements. Though it involves a large up-front payment, cash is the most economical choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the next best option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) enables you to pay a monthly rate determined by the energy you use, as with an electric bill. We generally don’t recommend these two options because you won't own the solar system and cannot use solar incentives. We advise working with a provider that offers multiple financing options. Ask each representative about what's available, and get more than one estimate for the best odds of keeping within your budget.

The table below lists the average payback periods for different capacities of solar systems in Quincy.

A 26% federal tax credit applies to new home solar systems purchased through 2032. Extra incentives may be available through local governments, usually in the form of rebates and special financing programs.

Solar System Capacity Estimated Payback period
1 kW 2.8 years
2 kW 5.5 years
5 kW 13.8 years
10 kW 27.6 years

Frequently Asked Questions About Solar in Quincy

How much money could I save by going solar in Quincy?

Most Quincy homeowners spend about $851 on energy each year. Your costs could drop by $843.67 for each kilowatt you generate after you pay off a solar array.

Is solar energy widely available in Quincy?

Yes, solar energy is spreading quickly in Quincy. Some homes already benefit from solar power on-site or through utility grids, and they're supported by a state solar economy with 5513 workers and counting.

Should I expect a boost in my property value after installing solar panels?

Yes, a solar PV system will raise your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you save on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How can I check my site's solar potential?

One common way to determine your home's solar viability is by using PVWatts. This free, powerful tool considers system size, local weather and topography, panel efficiency, and tree cover to determine how much energy your array could generate. However, it's not a substitute for consulting with a solar energy professional, who can create a full estimate with the most updated data.

What is a Quincy solar panel's average lifespan?

Modern solar panels are built to last. The average panel lasts at least 25 years. Cheaper panels tend to last shorter than premium models.

How long does it take to pay back a solar loan in Quincy?

The average payback period for a solar loan in Quincy is 15.6 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

How can I enhance my solar panels' performance?

To enhance your solar system's performance, you can implement the following steps:
  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

How does "net metering" work, and do I need to participate?

Net metering is a system that credits solar homeowners for any excess electricity they generate and feed back to the grid.

Some states or utilities require you to participate in net metering when installing your solar system, while others give you a choice. Either way, once you join, you'll earn a check or bill credit for your excess generation at a retail or wholesale rate.
