HOW VECTHOR WORKS

A solar tracker with no moving parts

Instead of turning the panel towards the sun, VectHor turns the sunlight towards the panel. A vertical bifacial panel and two fixed reflectors capture more energy in the morning and in the afternoon, when it is needed most.

Power measured on 17 June 2026 at the IMN-CSIC test field (Madrid), compared with a conventional south-facing panel tilted at 30°.

How it works throughout the day

1. Low sun

The sun shines straight onto the vertical panel. A conventional, south-facing panel only sees it at a grazing angle.

2. Direct light + reflectors

The panel receives direct sunlight and, in addition, the light sent by the reflectors.

3. Midday

The reflectors feed both sides of the panel and send part of the midday light back to the sky, when electricity is worth the least.

+49% more energy from the same installed capacity

That day, VectHor produced 10.6 kWh per kWp, compared with 7.1 for the conventional panel.
