How To Choose a Solar Company

Going solar can be a great way to reduce electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when evaluating if a solar installer is reliable.

Check Licensing

Hiring a licensed solar installer is critical. This ensures that the work is done properly using the most up-to-date installation methods. For solar thermal installations, Wisconsin requires a licensed HVAC contractor or plumber to serve the crew if the work involves heating equipment or potable water. There are fewer restrictions for solar PV systems, but either your city government or the Wisconsin Division of Safety and Buildings may have to review building plans before you begin.

Read Customer Reviews

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

Compare Multiple Quotes

To find a solar installer that works with your budget, get free, detailed quotes from at least three providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the most cost-effective option.

Ask About the Warranty

Top-notch solar installations should have strong workmanship and performance warranties. A workmanship warranty covers installation defects, such as poor alignment, poor wiring, or cracks in the panels. A performance guarantee ensures a minimum energy output. Comprehensive guarantees show that a solar company believes in its work.

Evaluate Financing and Incentives

Switching to solar power can help reduce your energy expenses over time. Be sure to weigh these aspects when judging the cost and value of solar panels.

  • Compare system purchase options: Solar panels may be paid for upfront or financed through a lease or loan. Confirm important financing details such as annual percentage rate (APR), fees, payment schedule, and ownership implications when financing your solar system.
  • Look into utility rebates: More financial incentives might be available from local power companies looking to encourage homeowners to switch to solar power. Contact your local utility provider to learn rebate values and qualification criteria, so you can determine your possible savings.
  • Research federal and state tax credits: A 26% federal tax credit for solar the applies to total system costs is available through 2032. Many states also have incentives. These credits offer substantial savings for solar customers.

Frequently Asked Questions About Solar in Sparta, WI

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

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

Yes, it's possible to use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, meaning that you can reap the savings and environmental benefits that come from using solar energy without having to completely switch over.

Generally speaking, your energy bills will decrease significantly 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 Sparta, the average amount someone can save is $1,481 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system once the payback period passes.

You might be pleasantly surprised at how quickly you can get a return on investment from your solar panels. In areas like Sparta with moderate sunlight, the period could last 13.6 years per 5 kW of power, but may be shorter if you have low electricity costs or a smaller energy capacity.

Net metering is a type of "power purchase agreement." If your utility or state offers net metering, you can return the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.

The answer depends on your specific needs and goals. In most cases, monocrystalline solar panels are the most efficient for homes in Sparta. However, if lowering cost is your top priority, then you may want to consider polycrystalline or thin-film 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.
