Factors that Affect Solar Panel Costs in Duncan

Cost is typically one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that affect your total cost in Duncan: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. Because of that, it's important to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs. The model of solar panels and equipment you get is another factor that will substantially influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more costly. Plus, solar equipment consists of more than just the solar panels themselves. You'll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when searching for a solar system that falls within your budget.

Solar Financing Terms

If paying for solar panels in cash is too expensive, solar loans are a popular route because they reduce your upfront costs and allow you to pay for your system over five to seven years on average. You'll have to consider the long-term cost of financing options, including the total interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or getting a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

The solar installer you go with to handle your switch to green energy can have an effect on your total costs. There are about 3 solar installation companies operating in Duncan, and each can charge varying amounts for labor and equipment. You may see national solar installers that have lower prices because of their larger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Contract: When looking over your solar company's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios like a system part breaking or the company going out of business.
  • 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 most likely has a solid reputation and is qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
  • Solar Panel Brands: Not all solar companies have the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you choose.
  • Warranty: Warranties that provide coverage for defective panels and repairs over around 25 years are the gold standard in the business, and offering that kind of warranty is one indication of a good company.

How long do solar panels last in Duncan?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time.
