Factors that Affect Solar Panel Costs in Castor
For many Castor homeowners, the decision to install a solar energy system depends on cost. However, the range of solar installation costs can be quite wide in Castor, with typical prices between $20,000 to $40,000. There are various factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to some different factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power production need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,370.The solar equipment you choose can bring your price up or down 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, more efficient panels could save you more over time on your power bills. Additionally, extra products, like solar batteries, can bring your total well above the Castor average.
Solar Financing Terms
Many homeowners find the average cost of solar in Castor to be too costly, even if the investment pays off over time. Thankfully, nearly every solar installer in the area offers financing options. Solar loans remarkably decrease upfront costs in most cases, but they also result in paying more over time due to interest.When figuring out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more upfront can lower the total interest paid over time.
Solar Panel Installation Company
Finally, the company you get to install your solar panel system can play a role in determining your pricing. Castor’s solar companies all have different labor costs and add varying upcharges to equipment. The size of the company sometimes plays the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because of greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since selecting a company can be a challenge, we have some tips to help you, such as:
- Installation Process: Make sure you’re aligned with the installer with regard to how the installation process will go and what needs to be done before your solar panels are installed, such as updating or replacing your electrical system or roof.
- 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 most likely has a good reputation and is qualified to get the job done well. Another way you can look into your installer’s reputation is by reading reviews.
- Warranty: Warranties that provide coverage for defective panels and repairs over around 25 years are the gold standard in the business, and offering such a warranty is one sign of a good company.
- Contract: It’s important to read your solar installer’s contract fully to understand what services they will provide, what the warranty covers and what you can expect about the project timeline.
EcoWatch's Castor, MO Solar Cost FAQs
What is the average cost of installing solar panels in Castor?
The average cost of solar panels in Castor is about $16,850 for a 5-kW system and $33,700 for a 10-kW system before the ITC, but the real cost will depend on certain factors like the type of solar panels you want, what size system you need and how much energy you use.
Is it better to lease or buy solar panels in Castor?
Leasing solar panels can be an option if you can’t afford to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.
Does Castor have a net metering program?
The majority of states offer net metering programs of some kind. Through these, you can get paid for the extra power your system produces 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 needs 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 buy between 20 and 35 panels to cover their typical energy usage.
