Factors that Affect Solar Panel Costs in Des Peres
There are many factors that can determine your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
Solar Equipment
One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to spend around $2,590 per kilowatt in Des Peres. The brand and kind of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive 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 can expect a higher equipment cost, but this can typically lead to more savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
If paying for a solar system 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 a term of, on average, between five and seven years. It's a good idea 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 back the loan.
Solar Panel Installation Company
The last significant cost factor you should consider is the installer you choose. Given the booming popularity of sustainable energy solutions in Des Peres, you'll have a great number of options to choose from, but each comes at various price points for labor and equipment. Additionally, some companies in Des Peres have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you find the right company for you, here are some tips to keep in mind:
- Installation Process: Make sure you're on the same page with the installer regarding how the installation process will go and what needs to be done before your solar system is installed, such as updating or replacing your electrical system or roof.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to get the job done well. Another way you can research your installer's reputation is by reading reviews.
- Solar Panel Brands: Not all solar installers offer 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.
- Contract: Read the contract terms carefully to make sure you understand the overall cost, project timeline incentives and warranties.

EcoWatch's Des Peres, MO Solar Cost FAQs
What is the average cost of installing solar panels in Des Peres?
The average cost of solar panels in Des Peres is about $12,950 for a 5-kW system and $25,900 for a 10-kW system before the ITC, but the actual cost will depend on certain factors like the type of solar panels you want, what size system you need and how much energy you consume.
What other factors should I consider aside from cost when buying solar panels?
The upfront cost is a crucial factor to consider, but whether it's the most important for you depends on your goals for going solar. In places where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to think about are the quality and durability of your solar panels.
Can solar panels significantly reduce my energy bills?
It is possible to eradicate your electricity bills with solar panels, but for most homeowners throughout Des Peres, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.
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 the amount of sunlight your roof gets. You can take a 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 get between 20 and 35 panels to account for their typical energy usage.
