Strela tracker: two-axis, single mast
Designed and developed by Novacom. The only Bulgarian-made solar tracker: it follows the sun all day, and a seasonal arm changes the tilt for winter and summer.
- Up to 45% higher yield
- 6 bifacial modules, ≈ 3.5 kWp
- Single mast or trailer
- Manufactured in Bulgaria
The head turns through the day, following the sun from east to west. The arm changes the tilt by season: steep in winter, flat in summer. The bifacial modules add yield from light reflected underneath.

How Strela works
Six bifacial modules are mounted on a frame on a single mast. A rotating head follows the sun from east to west all day, and a seasonal arm changes the tilt: steep in winter, flat in summer. The model runs by itself; switch the season or stop the day with the slider.

Why a tracker
More energy from the same modules
up to 45%
higher annual yield than a fixed structure
2 axes
daily east–west rotation and seasonal tilt
1 mast
a small footing or a trailer, quick to install and relocate
For large ground-mounted parks we also supply and install standard single-axis trackers with two-in-portrait (2P) module layout: one torque tube, central drive and rows over 100 m long.
