Factors that Affect Solar Panel Costs in Greenville

There are many criteria that can influence your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power generation use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,840. The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more over time on your power bills. In addition, add-on products, such as solar batteries, can bring your total well above the Greenville average.

Solar Financing Terms

Many homeowners find the average cost of solar in Greenville to be too steep, even if the investment pays off over time. Thankfully, nearly every solar company in the area offers financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also lead to higher prices over time due to interest. Even though solar loans make switching to solar energy more accessible for Greenville homeowners, they can also raise the total you pay for your system due to interest. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar installer you choose to handle your switch to renewable energy can have an effect on your total costs. There are about 3 solar installation companies in Greenville, and each can charge different amounts for labor and equipment. Additionally, some companies in Greenville know more about local solar incentives and can help you take advantage of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

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

  • Reputation: Your solar installer should have a good reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Contract: Before you sign a contract with a solar installer, make sure to read it through fully so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, durability and efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.
  • Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the project completion timeline.

The average cost of solar panels in Greenville is about $14,200 for a 5-kW system and $28,400 for a 10-kW system before the ITC, but the actual cost will depend on things such as the type of solar panels you want, what size system you need and how much energy you consume.

What other factors should I consider apart from cost when buying solar panels?

The initial cost is a key factor to consider, but whether it's the most important for you depends on your goals for going solar. In cities where rooftop space is limited, efficiency can trump the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

Do solar panels increase the value of your home?

Solar panels can increase the value of your property by about 4%, according to research done by Zillow.

The specific figures will vary, but most experts agree that installing solar panels in Greenville is a worthwhile investment.

How many solar panels do I need to power my home?

To figure out how many solar panels you need, you should find out how much energy your home requires 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 household will need 20 to 35 panels.
