How Many Solar Panels Do I Need to Run a Mini Split? With Formula Ultimate Guide
The air conditioner’s power demand, solar panel efficiency, sun irradiation, and system losses must be considered to calculate the ideal quantity of solar panels.
Formulas and examples are below:
Determine the Mini Split AC’s Power Consumption:
Determine how much electricity your mini split air conditioner uses daily in watts or kilowatts.
The mini split air conditioner label or specification sheet usually contains this information.
Example: Suppose your mini split AC has a power consumption of 1,500 watts (1.5 kW).
Estimate Daily Energy Requirement:
To determine how much energy the mini split AC needs daily, multiply its power use by the hours it runs daily. The thermostat’s use and temperature may vary in this estimate.
Example: If your mini split AC runs for 8 hours per day:
Daily Energy Requirement = Power Consumption × Operating Hours Daily Energy
Requirement = 1.5 kW × 8 hours = 12 kWh (kilowatt-hours)
Account for Solar Panel Efficiency:
The effectiveness of the solar panels you intend to install should be considered. Solar power efficiency is estimated by how much power it generates from sunshine.
Example: Assuming your solar panels have an efficiency of 20% (0.20).
Consider System Losses:
Inverter efficiency losses, wire losses, shadowing, and dirt on the panels should all be considered. Calculate the percentage of these losses.
Example:
Considering system losses of 15% (0.15).
Estimate Solar Irradiation:
Solar irradiation is a location’s solar energy, measured in kWh/m2/day. Location, season, and climate affect sun irradiation.
Solar maps or local solar resources help you determine regional solar irradiation.
Example: Let’s assume the estimated solar irradiation in your location is 5 kWh/m²/day.
Calculate the Number of Solar Panels:
The following calculation can be used to estimate how many solar panels will be needed to run a mini split AC.
Number of Solar Panels = (Daily Energy Requirement) / (Solar Panel Efficiency × Solar Irradiation × System Losses)
Example:
Filling in the values from the last steps:
Number of Solar Panels = 12 kWh / (0.20 × 5 kWh/m²/day × 0.15)
Number of Solar Panels ≈ 12 kWh / 1 kWh/m²/day ≈ 12 solar panels
In this example, you would need approximately 12 solar panels to meet the daily energy requirement of the air conditioner, considering the given specifications, solar panel efficiency, system losses, and estimated solar irradiation.
A professional solar installer can evaluate your unique situation, consider additional variables, and provide accurate sizing for your solar panel system to meet the energy demands of the air conditioner efficiently.
It is critical to remember that the computations’ results only approximate the value.

To answer this question, here I discuss some factors that affect solar panel numbers to run a Mini Split.
These include,
- Energy Efficiency of Mini Splits
- Climate and Weather Conditions
- Energy Consumption of the Mini Split
- Solar Panel Efficiency
- Sunlight Availability and Geographic Considerations
- Solar Panel Tilt/Orientation
- Considering Battery Storage
- Roof Orientation and Space
Understanding these factors will help you accurately assess and avoid under or over-sizing your solar panel system for your mini split.
Energy Efficiency of Mini Splits
Solar panel requirements depend on your mini split system’s energy efficiency rating.
High SEER and HSPF values are desirable. These ratings represent system cooling and heating efficiency.
Higher SEER and HSPF ratings reduce energy use.
HSPF – Heating Seasonal Performance Factor.
SEER – Seasonal Energy Efficiency Ratio
Climate and Weather Conditions
Your mini split’s energy needs depend on the weather.
Hotter climates require more cooling and heating energy. Calculate solar panel needs based on seasonal fluctuations and peak consumption.
Energy Consumption of the Mini Split
Your mini-split system uses kWh. Consult the system’s specifications or manufacturer for energy usage.
This information is essential for evaluating the amount of solar panels needed to power your mini-split.
Solar Panel Efficiency
Solar panel efficiency influences mini-split system power requirements.
Higher-efficiency panels turn more sunshine into energy, increasing power output.
High-efficiency panels enhance energy production and reduce panel count.
Sunlight Availability and Geographic Considerations
The installation position determines solar energy potential.
USA regions vary in sunlight intensity, duration, and weather.
In places with more cloud cover or less sunlight, more panels may be needed to generate as much solar energy.
Sun zones, based on average sun radiation, divide the United States. Zone 1 is the sunniest, and Zone 7 is the least.
Solar irradiance maps or local solar professionals can establish your solar zone.
Let’s examine solar potential by location and the number of solar panels needed to power a mini-split.
| Solar Zone | States Included | Solar Potential | Minimum Mini Split Capacity (BTU) | Required Number of Solar Panels |
|---|---|---|---|---|
| Zone 1 | California, Arizona, Nevada | High | 12,000 BTU | 2-3 solar panels |
| Zone 2 | New Mexico, Texas (Western) | Moderate to High | 12,000 BTU | 3-4 solar panels |
| Zone 3 | Texas, Florida, Midwest | Moderate | 12,000 BTU | 3-4 solar panels |
| Zone 4 | Kansas, Missouri, Illinois | Moderate | 12,000 BTU | 4-5 solar panels |
| Zone 5 | New York, Pennsylvania, New England | Moderate | 12,000 BTU | 4-5 solar panels |
| Zone 6 | North Dakota, Minnesota, Wisconsin | Moderate to Low | 12,000 BTU | 5-6 solar panels |
| Zone 7 | Alaska, Pacific Northwest | Low | 12,000 BTU | 5-6 solar panels |
Solar Panel Tilt/Orientation
Solar panel orientation affects energy generation. Panels should face true south (Northern Hemisphere) or true north (Southern Hemisphere) to optimize sunlight.
Optimize energy capture by matching the tilt angle to the installation site’s latitude.
Deviating from these ideal angles may reduce power output and panel count.
The recommended solar panel tilt and orientation for several US locations are shown in the table below:
| Region | Recommended Tilt Angle | Recommended Orientation |
|---|---|---|
| Northeast | 30° to 40° | South |
| Mid-Atlantic | 30° to 40° | South |
| Southeast | 25° to 35° | South |
| Midwest | 30° to 40° | South |
| Southwest | 20° to 30° | South |
| Northwest | 30° to 40° | South |
| West Coast | 20° to 30° | South |
Roof Orientation and Space
Solar panel placement and roof orientation are critical.
Panels should face south to enhance daytime light exposure. To fit the necessary panels, the roof must be unobstructed.
Considering Battery Storage
Solar panels provide electricity during daylight, but what happens at night or on overcast days?
Battery storage lets you store energy at peak output and use it when the sun isn’t shining.
This keeps your mini split powered, increasing energy independence and decreasing grid dependence.
Local Regulations:
Local solar legislation and incentives must be researched. Some jurisdictions ‘ tax incentives, subsidies, and net metering programs reduce solar panel installation costs.
These criteria can help you decide how many panels your mini split needs.
