Factors that Affect Solar Panel Costs in Greenville

The cost of installing a solar system in Greenville can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The largest one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar installer you choose.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size. Solar power systems that have higher efficiency or power generation need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,720. The brand of solar panels and equipment you want is another factor that will largely affect costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Furthermore, solar equipment goes beyond just the solar panels themselves. You'll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when searching for a solar system that's in your budget.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a significant investment. That's why many Greenville homeowners choose to finance their solar panel systems to offset upfront costs. When trying to figure out your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar panel system can play a part in determining your pricing. Greenville's solar companies all have different labor costs and add varying upcharges to equipment. Companies that only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It's best to do some research and find a company that provides the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since choosing a company can be difficult, we have some tips to help you, such as:

  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to clarify any details you need to know with your solar installer, such as what permits you should acquire and how long the project will take.
  • Contract: Before you sign a contract with a solar installer, make sure you look it over fully so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Warranty: Companies typically offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Solar Panel Brands: The brand of solar panel you'd like to install plays a part in which company you should choose, since different companies have access to different panels.

EcoWatch's Greenville, SC Solar Cost FAQs

What is the average cost of installing solar panels in Greenville?

The average cost of solar panels in Greenville is about $13,600 for a 5-kW system and $27,200 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the kind of solar panels you want, what size system you need and how much energy you use.

Is it better to lease or buy solar panels in Greenville?

Leasing solar panels can be an option if you can't afford to pay upfront or get a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your property value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.

Does Greenville have a net metering program?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just offer you credit toward your future energy bills.

What solar power system size is right for my home?

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