How to Use This Calculator

Enter your drone fleet size and battery type

Start with the number of drones and their battery size. This is the primary energy input — a small DJI Mavic-class survey drone has a 0.05 kWh battery, while an industrial delivery drone can carry a 10 kWh pack. Enter how many full charges each drone needs per day: 3–5 for survey drones, 2–4 for agriculture, 4–8 for delivery operations with fast charging.

Set operational hours and location

Operational hours determines how much battery storage you need for nighttime or overcast periods. A 24/7 autonomous delivery hub needs full overnight battery capacity; a 6-hour daytime survey operation can run primarily on direct solar with minimal storage. Location (peak sun hours) affects panel sizing — remote agricultural and construction sites typically have excellent unshaded solar access.

Read the results

The calculator outputs total solar kW, battery storage for 2-day autonomy, peak charging demand (for inverter/charger sizing), infrastructure cost, and annual revenue potential by use case. The payback calculation attributes 15% of drone revenue to the charging infrastructure as its enabling share of the operation.

The Formula

Daily kWh per Drone = Battery kWh × Charges per Day Total Daily Fleet kWh = Daily kWh per Drone × Drone Count Solar kW = Total Daily kWh ÷ Peak Sun Hours ÷ 0.82 efficiency Battery Storage = Total Daily kWh × 2 days autonomy Peak Charging kW = Charger kW per Drone × (Drone Count ÷ 2) Total Cost = Solar Cost + Battery Cost + Landing Pad Infrastructure Payback = Total Cost ÷ (Annual Revenue × 15% infrastructure share)

The 2-day battery autonomy is standard for remote drone stations — it covers overcast days and equipment maintenance windows. The peak charging demand assumes half the fleet charges simultaneously, which is typical for staggered mission scheduling. Size your inverter and charger to handle this peak load, not the average.

Example

Agricultural drone fleet — 5 drones, Central Valley CA

A precision agriculture company operates 5 medium-sized drones for crop monitoring and spraying in California's Central Valley. Each drone charges 3x/day during an 8-hour field day.

Solar + battery cost~$11,250

Total station~$23,250

Annual revenue~$500,000/yr (5 drones × 250 days)

For a $500K/year agriculture drone operation, a $23K solar charging station is a small infrastructure investment. The station eliminates the need for diesel generators or grid connection at remote field sites, and the 15 kWh battery ensures continuous operations through morning cloud cover and drone swap scheduling.

FAQ

How much solar does a drone charging station need? ▼

It depends heavily on fleet size and drone type. A single small survey drone (0.05 kWh × 4 charges/day = 0.2 kWh) needs under 100W of solar panel. Five agriculture drones at 0.5 kWh × 3 charges = 7.5 kWh/day, requiring about 1.5 kW of solar. Twenty large inspection drones at 2 kWh × 2 charges = 80 kWh/day, requiring 20 kW of solar. Commercial delivery fleets (50 drones, 10 kWh, 4 charges) need 200+ kW — essentially a small solar farm at the hub.

What is an autonomous drone charging dock and what does it cost? ▼

An autonomous drone dock (also called a drone-in-a-box) allows drones to land, recharge, swap batteries, and redeploy without human intervention. Commercial systems like the DJI Dock, Skydio Dock, and Percepto AnyDrone start at $5,000–15,000 per landing pad for small drones. Heavy industrial docks capable of handling 10+ kg delivery drones cost $25,000–75,000 each. Beyond hardware, autonomous operations require FAA BVLOS (Beyond Visual Line of Sight) waiver — add 6–18 months and $50,000–200,000 in regulatory and software costs for large commercial deployments.

Why use solar instead of grid power for drone charging? ▼

Solar is the practical choice for remote locations where grid connection would cost $20,000–100,000+ per mile. Agriculture fields, pipeline corridors, construction sites, and wilderness monitoring stations often have no grid access. Solar + battery provides reliable 24/7 power with no fuel logistics. For urban drone hubs (delivery, surveillance), grid connection is typically cheaper unless the location is challenging (rooftop, remote park). The operational advantage of truly autonomous solar-powered stations — no fuel delivery, no power outages — often justifies the premium even where grid power is available.

How much battery storage does a drone charging station need? ▼

The standard design rule is 2 days of autonomy — enough to cover overcast weather and operational maintenance windows. For a 5-drone agriculture fleet at 7.5 kWh/day, that's 15 kWh of battery storage. For a 24/7 delivery hub, you also need to size for peak overnight demand — all drones may need to charge simultaneously for morning deployment. Add 20% overhead for battery degradation and temperature derating. LiFePO4 (lithium iron phosphate) batteries are preferred for outdoor stations due to thermal stability and 3,000+ cycle life versus 500 cycles for standard lithium-ion.
