AGROSCOPE

info

Switzerland, Conthey (Valais)

Agroscope, Research Center for Protected Agriculture
03.2022 – 11.2022
Tomato, bell pepper, lettuce, basilicum
20 m2 - 2 greenhouse compartments, with each 10m2 trial zone,
and 10m2 control zone

goals

Demonstrate the absence of impact of Voltiris’ spectral filtering
solar technology on selected standard greenhouse crops (tomato,
bell pepper, lettuce, and basilicum)

results

No measureable impacts on various growth metrics on all crops:
Plant biomass (digital biomass)
Yield
Plant height

A reduction of up to 15% of the plant perspiration has been
measured during the warmest months.

WR BLEISWIJK

info

The Netherlands, Bleiswijk (Zuid-Holland)

Wageningen University & Research, Greenhouse horticulture
02.2023 – 11.2023
Soilless vine tomato Marinice
200 m2 - 2 greenhouse compartments, with each 100m2. One
compartment, and one trial compartment.

goals

Demonstrate the absence of impact of Voltiris’ spectral filtering
solar technology on state-of-the-Art growing techniques applied
to standard soilless tomato cultivation.
The energetic yield of the 24 Voltiris modules will also be studied
in these trials.

results

We’re still waiting for the final results to come in.

CVETMO

info

France, Saint-Denis-en-Val (Loiret)

CVETMO Experimentation center for Centre-Val de Loire growers
02.2023 – 11.2023
Soilless cucumber, umbrella cultivation, PROLOOG (Rijk Zwaan)
80 m2 - 8 small (10m2) compartments , 4 with Voltiris spectral
filters, 4 with a control film

goals

Study the growth and health of cucumber crop which is
intensively cultivated in the Centre-Val de Loire.
Special care will be given to the study of pest and beneficial
insect populations below the spectral filters.Study the growth and health of cucumber crop which is

Sana Giardin

info

Switzerland, Saas (Graubünden)

Sana Giardin
Start: 08.2022
Various vegetables and ornmental flowers
40 m2 - 1 wide-span greenhouse equipped with 15 Voltiris
modules, covering a ground surface of 45 m2

goals

Demonstrate the ability to retrofit, i.e. the ability to build the
modules in any type of greenhouse. Here the modules were built
in a 40 years-old Gysi wide-span greenhouse.

results

The modules were easily installed inside of the greenhouse. No
reduction of the agronomical yield below the modules has been
measured.
