Solar energy instead of batteries
The integrated panel converts sunlight into energy for a mini motor, which drives the gears and sets the model in motion.
Three construction machines in one box
Build an excavator, cement mixer, and bulldozer from a single set of parts. Easily switch models thanks to a clear step-by-step guide.
Supports creativity and STEM skills
Kids practice fine motor skills, logical thinking, and understanding of renewable energy principles through playful construction.
The 3-in-1 solar kit gives children a unique experience of building and play. Thanks to the integrated solar panel, sunlight is converted into motion that drives the built model via gears. No batteries—just clean, fun energy.
Each model is finished with decorative stickers and assembled following step-by-step illustrated instructions. Ideal for a first introduction to renewable energy and STEM principles.
- 3 in 1: excavator, cement mixer, bulldozer
- Solar-powered: panel powers a mini motor and gear train
- Educational fun: develops fine motor skills and logic
- No batteries: eco-friendly and cost-effective solution
- Compact packaging: great for travel and gifting
