Factors that Affect Solar Panel Costs in St Johns

While the average cost of a solar system in St Johns is $10,231, your actual cost may differ. There are quite a few factors that can have a sizable impact on the cost of a solar panel installation. Below are some of the more crucial things to keep in mind.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. For that reason, it's a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your energy needs. The brand and type of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar companies in St Johns provide solar loans, which reduce the initial cost of installing a solar system. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay off the loan.

Solar Panel Installation Company

The solar installer you hire to handle your switch to renewable energy can play a role in your total costs. There are about 3 solar installation companies in St Johns, and each can charge different amounts for labor and equipment. The size of the company sometimes plays the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of greater resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels

The solar installer you choose will be a major factor in determining not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should take into account, such as:

  • Contract: Before signing a contract with a solar company, make sure you read it through carefully so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what the warranty covers and what services you can expect from them.
  • Reputation: Your solar installer should have a good reputation as a company and have proven expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, such as when the site survey will be done and how long it will take.
  • 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 substantial role in the company you go with.
