Factors that Affect Solar Panel Costs in Franklin

For many Franklin homeowners, the decision to adopt solar energy comes down to cost. However, the range of solar installation costs can be quite wide in Franklin, with typical prices between $20,000 to $40,000. There are a few factors that considerably influence the price you’ll pay, which we'll go over below.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more energy your household uses, the larger your system will likely need to be. You can expect to spend around $3,580 per kilowatt in Franklin.The kind of solar panels and equipment you get is another factor that will greatly impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more expensive. 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 looking into a solar system that’s in your budget.

Solar Financing Terms

Most solar installers in Franklin have solar loans, which reduce your upfront costs of installing solar panels.Though solar loans make switching to solar energy more accessible for Franklin homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar installer you go with to handle your switch to green energy can play a part in your total costs. There are about 3 solar panel companies operating in Franklin, and each can charge varying amounts for labor and equipment.Additionally, some companies in Franklin know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

Since the model of solar panels and the installation company you choose has an impact on your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Installation Process: Make sure you’re on the same page with the company regarding how the installation process will go and what needs to be done before your solar panels are installed, such as repairing your electrical system or roof.
  • Warranty: A high-quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: Before you sign a contract with a solar company, make sure to look it over carefully 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 kind offers varying levels of quality, longevity and efficiency. They will come at different price points as well. The company you choose affects which solar panel brands you have access to.
