CAMPOS, Claudia Guimarães Camargo; VIEIRA, Hamilton Justino; BACK, Álvaro Jose  e  SILVA, Aparecido Lima da. The global solar radiation flow on altitude vineyards in São Joaquim, state of Santa Catarina. Rev. Bras. Frutic. [online]. 2013, vol.35, n.3, pp.722-729. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452013000300008.

This study aimed to evaluate and quantify the partition of energy in wine grape vineyards (Vitis vinifera L.), in São Joaquim/SC. It was considered three distinct positions of the solar radiation sensors: facing east, west and at the top of the canopy. It was observed that in vineyards conducted using the trellis system and positioned north-south, the diurnal cycle of solar radiation presents different characteristics at the east and west sides of the canopy, both in relation to the availability, as well as the intensity of radiation. On average, around 10a.m. that occurs the greater availability of solar radiation incident by the sensor facing East (363W.m-2) and by the sensor facing West occurs around 4p.m. (290W.m-2). The maximum solar radiation incidence on the canopy, average daily cycle, is recorded close to 13p.m. (612W.m-2). Approximately 30% to 40% of the incident solar radiation is available to the east and west sides of the canopy, with superior value to face east. In the study area, there was greater availability of solar radiation in the months of November and December, a period that corresponded to the greater growth of the vine branches.
