Factors that Affect Solar Panel Costs in Hillsborough

Though the average cost of a solar system in Hillsborough is $5,867, your actual cost may be higher or lower than that. There are many factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it's important to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. The kind of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more in the long run on your power bills. Additionally, add-on products, such as solar batteries, can bump up your total well above the Hillsborough average.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be financially overwhelming. Solar loans are provided by most installers in Hillsborough, which can lower, or in some cases completely eliminate, your upfront costs to make solar more affordable. However, the interest on solar loans also increases your overall costs, so it's important to consider that as well. You can always reduce the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

The solar company you pick will play a role in your total cost to make the switch to solar power. Different companies will charge different amounts for the equipment and labor. You may see national solar installers that have lower prices because of their bigger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels

Since the type of solar panels and the installation company you choose significantly influences 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:

  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you go with.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to get the job done well. Another way you can verify your installer's reputation is by reading reviews.
  • Contract: When reading through your solar installer's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios such as a system component breaking or the company going out of business.
  • Installation Process: When making the switch to solar energy, it's important to maintain an open line of communication with your solar panel company. Confirm that you understand how the installation process will go and the completion timeline.
