SolarWing. How far can every watt take us?

SolarWing represents the long-term extension of the Kyte research program into highly energy-efficient, solar-assisted aircraft. It is not a product. It is an unanswered question worth chasing.

— Central research question

When does adding solar energy
actually make an aircraft better?

This is not obvious. Solar panels add mass. Mass adds power draw. There is a real, measurable point where a solar-assisted aircraft outperforms its pure-battery equivalent — and a point where it doesn't. Finding that point, honestly, is the research.

CHAPTER 02
— Research disciplines

The disciplines SolarWing
quietly forces together.

— DISC.01

Low-drag aerodynamics

Every point of extra drag steals from useful flight time.

— DISC.02

Lightweight structures

Composites, layup, and structural intelligence.

— DISC.03

Solar cell selection

Efficiency, weight, curvature tolerance, integration.

— DISC.04

MPPT electronics

Extracting the last usable watt from varying sunlight.

— DISC.05

Battery management

Chemistry, safe charge in flight, thermal envelope.

— DISC.06

Electric propulsion

Motor / propeller efficiency across the flight envelope.

— DISC.07

Thermal management

Cells, packs, ESCs — heat costs efficiency.

— DISC.08

Energy-aware autonomy

Decisions shaped by sunlight, wind, and mission left.

— DISC.09

Long-endurance planning

Mission design when hours become the unit.

This is a long journey.
SolarWing does not yet exist.

SolarWing is what Kyte might grow into once we understand energy well enough. If, by then, the honest data says a solar aircraft is genuinely better — we'll build one.
