Solar photovoltaic greenhouses have become more popular, especially in the countries of southern Europe, due to specific government remuneration policies. However, many agronomic questions need to be addressed. This research was carried out in three types of commercial greenhouses covered with different materials (polycarbonate modules – PCM, traditional – TPM and innovative semi-transparent – IPM photovoltaic modules) with the aim to verify the compatibility of solar energy production with the production of high-quality wild rocket (Diplotaxis tenuifolia L.). IPM may satisfy the entire electricity demand of a commercial greenhouse. Yield for rocket grown in TPM was lower than for IPM and PCM. Antioxidant properties and dry weight decreased as a consequence of decreasing cumulative photosynthetic photon flux density. Nitrate content in TPM was higher (about 10.000 mg·kg⁻¹ FW) than the maximum limits allowed by EC Regulation No. 1258/2011, whereas it was lower in IPM and PCM (1.805 and 668 mg·kg⁻¹ FW, respectively). The results suggest that it is possible to combine solar energy production with high-quality wild rocket production, using innovative semi-transparent PV modules.

Słoneczne szklarnie fotowoltaiczne stały się popularne, zwłaszcza w krajach południowej Europy, ze względu na specyficzną politykę rządową zwrotu kosztów. Jednakże należałoby zająć się niektórymi rozwiązaniami agrotechnicznymi. Niniejsze badanie przeprowadzono w trzech typach komercyjnych szklarni pokrytych różnymi materiałami (moduły polikarbonowe – PCM, typowe – TPM oraz innowacyjne półprzezroczyste – IPM moduły fotowoltaiczne) w celu zweryfikowania kompatybilności produkcji energii słonecznej z produkcją dzikiej rukoli o wysokiej jakości (Diplotaxis tenuifolia L.). IPM może zaspokoić całość wymagań elektryczności komercyjnej szklarni. Plon rukoli rosnącej w TPM był niższy niż dla IPM i PCM. Właściwości antyoksydacyjne oraz sucha masa obniżyły się w rezultacie zmniejszającego się skumulowanego zagęszczania strumienia fotonów. Zawartość azotanów w TPM była wyższa (około 10 000 mg·kg⁻¹ FW) niż maksymalne granice dopuszczane przez Regulację UE Nr 1258/2011, a niższa niż w IPM i PCM (odpowiednio 1805 i 668 mg·kg⁻¹ FW). Wyniki sugerują, że możliwe jest połączenie produkcji energii świetlnej z produkcją wysokiej jakości dzikiej rukoli przy użyciu innowacyjnych półprzezroczystych modułów PV.
