Factors that Affect Solar Panel Costs in St Peters
There are a number of factors that can play into your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
When it comes to estimating the cost of a solar energy system in St Peters, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home's energy usage, which you can figure out by looking at past power bills. Your total cost can increase by around $2,590 for each additional kilowatt you need. The model of solar panels and equipment you choose is another factor that will considerably influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Moreover, solar equipment is more than just the solar panels themselves. You'll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when researching a solar system that's in your budget.
Solar Financing Terms
If paying for a solar system out of pocket is too expensive, solar loans are a solid route because they lower your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years. 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'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 remarkably.
Solar Panel Installation Company
A final factor to consider when trying to evaluate the cost of solar for your home or business in St Peters is the company you hire to install your solar panel system. As with choosing a company to build a deck or pool, for example, you'll have many options for 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 equipment 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
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 select the right company for you, here are some tips to keep in mind:
- Solar Panel Brands: Each solar panel brand and type has varying levels of quality, durability and efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.
- Contract: Although reading through a contract can take a lot of time, it's important to do it carefully so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
- Reputation: Long-standing companies likely have a solid reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
- Installation Process: When making the switch to solar energy, it's necessary to keep an open line of communication with your solar company. Make sure you understand how the installation process works and the completion timeline.

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