Factors that Affect Solar Panel Costs in Radnor

There are a number of factors 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 does the installation.

Solar Equipment

When it comes to estimating the price of a solar system in Radnor, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home’s energy consumption, which you can gauge by looking at past electricity bills. Your total cost can increase by about $3,550 for each additional kilowatt you need.There are several different solar panel brands and the one you pick also changes the cost. Generally speaking, the brands that have better efficiency tend to also cost more. Additionally, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Most solar installers in Radnor provide solar loans, which reduce your upfront costs of installing solar panels.Even though solar loans make adopting solar energy more accessible for Radnor homeowners, they can also raise 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 panel installation company you pick will play a role in your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.Larger national companies usually have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

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

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can check your installer’s reputation is by reading reviews.
  • Warranty: If you care about the longevity of your solar system, verifying that your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
  • Installation Process: Get detailed information from your solar installer about the installation process and what to expect, such as when the site survey will be done and how long it will take.
