Factors that Affect Solar Panel Costs in Walnut

Cost is usually one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that affect your total cost in Walnut: 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

The size of the solar system you need for your household is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $2,730. 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. In addition, extra products, like solar batteries, can bump up your total well above the Walnut average.

Solar Financing Terms

Many homeowners find the average cost of solar in Walnut to be too costly, even if the investment pays off over time. Fortunately, nearly every solar installer in the area provides financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in higher prices over time because of interest. You'll have to consider the long-term cost of financing options, including the amount of 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 more than the principal cost. Making a larger down payment or finding a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Walnut is the company you choose to install your PV system. As with choosing a company to install new cabinets, for instance, you'll have no shortage of solar installers that offer a range of services at different costs. You may notice national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

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 efficiency, production, and durability, it's important to select 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 respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to install your solar system. Another way you can check your installer's reputation is by reading reviews.
  • Warranty: Warranties that cover defective panels and repairs over a long period of time such as 25 years are the best you can get in the business, and offering that kind of warranty is one mark of a good company.
  • Contract: When looking 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 like a system part breaking or the company going out of business.
  • Solar Panel Brands: The model of solar panel you need to get plays a role in which installer you should go with, since different companies have access to different panels.
