Factors that Affect Solar Panel Costs in Germantown

There are several criteria that can play into your total 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

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. For that reason, it's a priority to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use. Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Germantown, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Germantown to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also result in a higher cost over time due to interest. 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 sometimes even your APR by putting more money down.

Solar Panel Installation Company

A final consideration when trying to evaluate the cost of solar for your home or business in Germantown is the company you hire to install your PV system. As with choosing a company to install new cabinets, for instance, there's no shortage of solar installers that offer a range of services at different costs. Larger national companies generally have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar panel company you go with will influence not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should consider, such as:

  • Solar Panel Brands: The brand of solar panel you need to install plays a role in which installer you should go with, since different companies have access to different panels.
  • Contract: When looking through your solar company's contract, ask questions about any terms you're not sure of and make sure you understand what happens in scenarios such as a system part breaking or the company going out of business.
  • Warranty: An all-inclusive, long-term warranty can help keep your solar panels running for years to come and save you money on part replacement and repairs.
  • Reputation: Make sure your solar company has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by past customers and solar experts like the EcoWatch team.

The average cost of solar panels in Germantown is about $13,000 for a 5-kW system and $26,000 for a 10-kW system before the ITC, but the real cost will depend on things such as the model of solar panels you want, what size system you need and how much energy you consume.

Are solar panels free in Germantown?

Solar panels aren't free in Germantown, but there are some options that can make getting them more feasible, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that you can take advantage of.

Can solar panels eliminate my electricity bills?
