WHY WE BUILD
MISSION
Engineering is learned
by making it real.
A solar car is a full system problem: electrical, mechanical, structural, aerodynamic, operational, and human.
HelioTech gives students a place to turn classroom ideas into hardware that must survive testing, integration, and competition.
More about HelioTech ↗Build
Fabricate, solder, assemble, wire, document, and integrate the vehicle as a complete system.
Validate
Test under real constraints, learn from failures, and carry those lessons into the next revision.
/03
ADVANCED CAR
SYSTEMS MATRIX
One vehicle.
Many systems.
Every subsystem has to work independently — and then work together when the car is moving.
Solar + battery
Energy generation, MPPT integration, storage, distribution, protection, and monitoring.
Explore technical systems ↗PCB network
Custom boards connect driver controls, displays, telemetry, sensing, and vehicle subsystems.
See the PCB system ↗Structure + motion
Chassis, suspension, steering, braking, packaging, and the interfaces between them.
See the cars ↗Telemetry + data
Vehicle information moves from sensors to controllers, displays, and engineering analysis.

VEHICLES
RACE PROGRAM
From the drawing board
to the starting line.
Each car carries forward what the team learned from the last one.
IN DEVELOPMENT / 2027
Advanced single-seater
The next HelioTech vehicle moves into the Advanced Division with a new architecture, custom electronics, and a deeper level of student-designed integration.

Second consecutive title.
HelioTech returned to the Solar Car Challenge and earned another Cruiser Division championship.
The first championship.
The team’s Cruiser program established the platform for the next generation of HelioTech vehicles.
