Factors that Affect Solar Panel Costs in Marietta

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

Solar Equipment

One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to pay about $2,550 per kilowatt in Marietta. The kind of solar panels and equipment you get is another factor that will substantially affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Plus, solar equipment goes beyond just the solar panels themselves. You'll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when researching a solar system that falls within your budget.

Solar Financing Terms

Solar panels can save you money on energy bills over time, but they can also be a significant investment. That's why many Marietta homeowners opt to finance their solar panel systems to offset upfront costs. While solar loans make adopting solar energy more accessible for Marietta 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 avoid paying as much in interest.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in Marietta is the company you get to install your solar system. As with choosing a company to build a deck or pool, for example, you'll have no shortage of solar installers that provide a range of services at different price points. Some companies only sell products with high efficiency and therefore a higher price point — 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 choose a company that offers the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels

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

  • Reputation: Make sure your solar system 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: Each solar panel brand and type has varying levels of quality, longevity and energy efficiency. They will come at different price points as well. The company you choose plays a role in which solar panel brands you have access to.
  • Contract: Read the contract terms thoroughly to make sure you understand how much it will cost, project completion timeline rebates and warranties.
  • Warranty: Many companies offer different kinds of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.

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

The average cost of solar panels in Marietta is about $12,750 for a 5-kW system and $25,500 for a 10-kW system before the ITC, but the real cost will depend on stuff such as the model of solar panels you want, what size system you need and how much energy you consume.

Is cost the most important consideration when buying solar panels?

Cost is without a doubt one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

Can solar panels significantly reduce my electricity bills?

It is possible to eliminate your electricity bills with solar panels, but for most homeowners in Marietta, 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 often do you have to replace solar panels?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
