The Complete Guide to Solar Panels in Arkansas (2025)

Arkansas is one of the most promising states in the Southeast for solar energy, yet many homeowners remain unsure about whether solar panels make sense for their home. In this comprehensive guide, we will walk you through everything you need to know about going solar in the Natural State, from understanding Arkansas's excellent solar potential to breaking down costs, incentives, and the installation process step by step.

Arkansas's Solar Potential: Better Than You Think

Arkansas receives an average of 5.0 to 5.2 peak sun hours per day, which places it solidly in the top tier of solar-viable states east of the Mississippi River. To put this in perspective, Germany, the world's former leader in solar adoption, receives only about 3.0 peak sun hours per day. Arkansas's solar resource is more than 60% stronger than one of the world's most successful solar markets.

The state's latitude, between 33 and 36.5 degrees north, provides excellent year-round solar exposure. While summer months naturally produce more energy (averaging 6.0 to 6.5 peak sun hours from May through August), even the shortest winter days in December and January still deliver 3.5 to 4.0 peak sun hours. This means your solar panels will be generating meaningful electricity every single month of the year.

Cities across the state benefit from this resource. Little Rock averages approximately 217 sunny or partly sunny days per year. Jonesboro, Fayetteville, Fort Smith, and Pine Bluff all see similar solar exposure, making solar viable virtually anywhere in Arkansas. Our installations in every corner of the state consistently meet or exceed production estimates.

How Solar Panels Work

Solar panels convert sunlight into electricity through the photovoltaic effect. Each panel contains dozens of solar cells made from semiconductor materials, typically silicon. When photons from sunlight strike these cells, they knock electrons loose from their atoms, creating a flow of electrical current. This direct current (DC) electricity is then converted to alternating current (AC) by an inverter, making it compatible with your home's electrical system and the utility grid.

A complete residential solar system includes several key components:

• Solar panels - The modules that capture sunlight and generate DC electricity
• Inverter(s) - Converts DC power to AC power (string inverters, microinverters, or power optimizers)
• Racking and mounting - Secures panels to your roof or ground mount
• Electrical panel and wiring - Connects the system to your home's electrical system
• Net meter - Tracks electricity sent to and drawn from the grid
• Monitoring system - Allows you to track production and performance in real time

Types of Solar Panels: Which Is Right for Your Home?

Monocrystalline Panels

Monocrystalline panels are the most popular choice for residential installations and the type we install most frequently at Energy Future Arkansas. Made from a single crystal of silicon, they offer the highest efficiency ratings, typically between 20% and 22.8%. Premium brands like SunPower (Maxeon cells reaching 22.8% efficiency), REC Alpha Pure-R (22.3%), and LG NeON R (22.0%) represent the top tier of monocrystalline technology. These panels produce more power per square foot, which is particularly important if your roof space is limited.

Polycrystalline Panels

Polycrystalline panels are made from multiple silicon crystals melted together and are identifiable by their blue, speckled appearance. They typically achieve efficiencies between 16% and 18%, which means you need more roof space to generate the same amount of power as monocrystalline panels. However, they come at a lower price point and brands like Canadian Solar and Trina Solar offer reliable polycrystalline options. For homeowners with ample roof space and a tighter budget, polycrystalline panels can be a practical choice.

Thin-Film Panels

Thin-film panels are less common in residential applications but worth understanding. They are lighter and more flexible, making them suitable for certain commercial or unconventional installations. However, their efficiency ratings (11% to 15%) are significantly lower than crystalline panels, and they require considerably more space. We generally do not recommend thin-film for typical Arkansas homes.

System Sizing for Arkansas Homes

Properly sizing your solar system is one of the most critical decisions in the process. An undersized system leaves savings on the table, while an oversized system may produce more electricity than you can use or get credit for under Arkansas's net metering rules.

The average Arkansas household consumes approximately 1,100 to 1,200 kWh of electricity per month, though this varies significantly based on home size, insulation quality, HVAC efficiency, and personal usage habits. To offset this consumption, a typical Arkansas home requires a solar system between 7 kW and 10 kW.

Here is a general sizing guide based on monthly electricity bills:

• $100-$130/month (~900-1,100 kWh) - 6 to 7 kW system (15-18 panels)
• $130-$170/month (~1,100-1,500 kWh) - 7 to 9 kW system (18-23 panels)
• $170-$220/month (~1,500-2,000 kWh) - 9 to 12 kW system (23-30 panels)
• $220+/month (2,000+ kWh) - 12+ kW system (30+ panels)

Our team uses satellite imagery, utility bill analysis, and site-specific shading data to design systems that are precisely tailored to each customer's needs. You can get a quick preliminary estimate using our Solar Savings Calculator.

Cost Breakdown: What Solar Really Costs in Arkansas

The cost of solar in Arkansas currently ranges from $2.50 to $3.20 per watt before incentives, depending on system size, equipment quality, and installation complexity. This places Arkansas in the lower-to-middle range nationally, making solar here an excellent value proposition.

Here is what that translates to for common system sizes:

• 6 kW system: $15,000 - $19,200 before incentives; $10,500 - $13,440 after 30% federal tax credit
• 8 kW system: $20,000 - $25,600 before incentives; $14,000 - $17,920 after tax credit
• 10 kW system: $25,000 - $32,000 before incentives; $17,500 - $22,400 after tax credit
• 12 kW system: $30,000 - $38,400 before incentives; $21,000 - $26,880 after tax credit

The cost per watt typically decreases as system size increases, which is why larger systems often offer better value. A detailed breakdown of costs includes panels (30-35% of total), inverter(s) (10-15%), racking and hardware (10%), electrical work (10-15%), permitting and interconnection (3-5%), and labor (20-25%).

Net Metering in Arkansas

Net metering is the policy that allows you to send excess solar electricity back to the grid and receive credit on your utility bill. Arkansas has a net metering policy that applies to all investor-owned utilities and electric cooperatives, though the specific terms can vary by utility.

Under current Arkansas net metering rules:

• Residential systems up to 25 kW are eligible for net metering
• Excess generation is credited at the full retail rate on a monthly basis
• Credits can roll over month to month within the billing year
• At the end of the annual period, excess credits may be compensated at the avoided cost rate, which is lower than retail
• Your utility may charge a small monthly customer charge regardless of net metering credits

We recommend sizing your system to offset 90-100% of your annual consumption. This maximizes your savings while minimizing the risk of overproduction that would be compensated at the lower avoided-cost rate. Understanding these details is essential, and our team designs every system with your specific utility's net metering policy in mind.

Installation Timeline: What to Expect

From your initial consultation to flipping the switch, the complete solar installation process in Arkansas typically takes 6 to 12 weeks. Here is the general timeline:

1. Consultation and site assessment (Week 1): We evaluate your home, review your electricity bills, and discuss your goals.
2. System design and proposal (Week 1-2): Our engineers create a custom system design with production estimates and financial projections.
3. Contract signing and permitting (Week 2-4): Once you approve the design, we handle all building permits and utility interconnection applications.
4. Equipment procurement (Week 3-6): We order your panels, inverter, and hardware from our supplier network.
5. Installation (Week 6-8): Our crew completes the physical installation, typically in 1 to 3 days for a residential system.
6. Inspection and utility approval (Week 8-12): Your local building department inspects the system, followed by utility meter installation and permission to operate.

The longest delays usually occur during the permitting and utility interconnection stages. Our team manages this entire process for you, keeping you informed at every step.

Choosing a Solar Installer in Arkansas

The installer you choose is just as important as the equipment on your roof. Here are the key factors to evaluate when selecting a solar company in Arkansas:

• NABCEP certification: The North American Board of Certified Energy Practitioners certification is the gold standard in solar. Our entire design team holds current NABCEP certifications.
• Local experience: An installer familiar with Arkansas building codes, utility interconnection requirements, and weather conditions will deliver better results. We have been exclusively serving Arkansas since 2017.
• Licensing and insurance: Ensure your installer holds a valid Arkansas electrical contractor license and carries comprehensive liability and workers' compensation insurance.
• Warranty coverage: Look for a 25-year production warranty on panels, 10-25 years on inverters, and a meaningful workmanship warranty from the installer. We offer a 10-year workmanship warranty on all installations.
• Transparent pricing: Reputable installers provide detailed, itemized quotes. Be cautious of companies that only present monthly payment figures without full cost disclosure.
• Reviews and references: Check Google reviews, BBB ratings, and ask for references from past customers in your area.

What to Expect in Year One

Your first year with solar panels will be a learning experience. Here is what most Arkansas homeowners experience:

Spring and summer (March-September): This is when your system will produce the most electricity. In peak summer months, many of our customers generate more electricity than they consume, building up net metering credits for the winter. It is common to see your electricity bill drop to the minimum customer charge ($10-$15/month) or even receive credits during these months.

Fall and winter (October-February): Production naturally decreases as days shorten and the sun sits lower in the sky. Most homeowners will draw some electricity from the grid during these months, using the credits they accumulated over summer. December and January are typically the lowest production months, but your panels are still generating meaningful electricity every clear day.

Annual results: Over a full year, a properly sized system in Arkansas will typically offset 85-100% of your electricity consumption. Based on our installation data, the average homeowner saves between $1,200 and $1,800 per year on electricity, with a payback period of 8 to 12 years after the federal tax credit. After payback, those savings continue for the remaining 15 to 20 years of the system's warranted life.
