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 dependent on several factors. The largest one is your system size, and other factors include equipment choices, financing options and the solar company you choose.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. That’s why it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs.The kind of 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 in the long run on your electric bills. Additionally, extra products, like solar batteries, can bump up your total well above the Greenville average.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be a challenge. Solar loans are provided by most installers in Greenville, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable.Though solar loans make switching to solar energy more accessible for Greenville homeowners, they can also raise the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
A final factor to consider when trying to figure out the cost of solar for your home or business in Greenville is the company you choose to install your solar panel system. Similar to choosing a company to renovate your kitchen, for example, there are plenty of solar installers that offer a range of services at different price points.You may see national solar installers that have lower prices due to their larger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

- Warranty: A comprehensive, 25-year warranty can help keep your solar panels running smoothly and save you money on repairs and maintenance.
- Solar Panel Brands: Each solar panel brand and type has varying levels of quality, longevity and efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.

Broadly speaking, it costs about $20,350 for a 5-kW system and $40,700 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or higher quality panels, or if you have above-average energy usage. On the flip side, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.
What other factors should I consider aside from cost when buying solar panels?
Cost is without a doubt one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.
Can solar panels significantly reduce my power bills?
It is possible to eliminate your electricity bills with solar panels, but for most homeowners in Greenville, that will require at least a 10-kW system. Not all homes can accommodate 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?
The exact number of solar panels you need depends on your household energy usage and the average daily sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to install between 20 and 35 panels to cover their typical energy usage.
