Factors that Affect Solar Panel Costs in St John

For many St John homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in St John, with typical prices between $20,000 to $40,000. There are various factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to spend around $2,590 per kilowatt in St John. There are many different solar panel brands and the one you choose also affects the cost. Usually, the brands that offer higher efficiency tend to also be more expensive. Plus, 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

If paying for solar panels out of pocket is out of reach, 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 loans, including the amount of interest you'll pay over the length of the loan. If you can only 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 interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The solar company you hire to handle your switch to green energy can have an effect on your total costs. There are about 3 solar panel companies in St John, and each can charge different amounts for labor and equipment. Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and choose a company that has the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels

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

  • Warranty: If you're worried about the durability of your solar energy system, making sure your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Contract: Before signing a contract with a solar company, make sure to look it over fully so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
  • Installation Process: When making the switch to solar, it's crucial to maintain an open line of communication with your solar installer. See to it that you understand how the installation process works and the project timeline.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, durability and efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.

EcoWatch's St John, MO Solar Cost FAQs

How much does it cost to install solar panels in St John?

This is a tough question to answer precisely, because the cost depends on many factors. Broadly speaking, it costs about $12,950 for a 5-kW system and $25,900 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or higher quality panels, or if you have above-average energy usage. Conversely, you can spend less if you choose a smaller solar panel system or less expensive solar panels.

Should I lease or buy solar panels in St John?

Leasing solar panels can be an attractive choice, because it usually comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any incentives and your home value won't increase. Buying solar panels is a better option if you want to get the most savings.

Can you sell solar power back to the grid in St John?

Most states have net metering programs of some kind. Through these, you can either get paid for the extra power your system generates or or receive credits to put toward future electricity bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How many solar panels should I get to power my home?

The exact number of solar panels you need depends on your household energy consumption and how much sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to cover their typical energy usage.
