Factors that Affect Solar Panel Costs in Greenville

There are a number of criteria that can determine your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. Because of that, it’s a priority to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs.The model of solar panels and equipment you get is another factor that will largely influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Plus, solar equipment goes beyond just the solar panels themselves. You’ll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking into a solar system that falls within your budget.

Solar Financing Terms

Solar panels can save you money on power bills over many years, but they can also be a significant investment. That’s why many Greenville homeowners opt to finance their solar panel systems to offset upfront costs.However, the interest on solar loans also adds to your overall costs, so it’s important to consider that as well. You can always lower the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

The solar installation company you select will impact your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.Larger national companies typically have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a large number of companies to choose from in Greenville, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be tough, so here are some tips to help you decide:

  • Reputation: Make sure your solar installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by previous customers and solar experts like EcoWatch.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and how much efficiency they need. Even though there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of options before making your decision.
  • Warranty: Warranties that provide coverage for replacement parts and repairs over around 25 years are the best you can get in the business, and offering that kind of warranty is one mark of a quality company.
  • Installation Process: An important thing to understand when adopting solar power is the installation process itself. Be sure to align on any details you need to know with your solar company, such as what permits you should acquire and what the project timeline is.

EcoWatch's Greenville, WI Solar Cost FAQs

How much does it cost to install solar panels in Greenville?

This is a tough question to answer precisely, because the cost depends on a few different factors. Generally speaking, it costs about $19,400 for a 5-kW system and $38,800 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Can you get solar panels for free in Greenville?

You can’t get solar panels for free in Greenville. However, you may still be able to get them on a lower budget. You can lease solar panels for a low upfront cost or, if you’d prefer to own your solar panels, you can finance them with a solar loan.

How much can I save on power bills after installing solar panels?

It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Greenville, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.

How many solar panels should I get to power my home?

To figure out how many solar panels you need, you should find out how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
