Solar Radiation

Solar radiation sometimes referred to as insolation, provides the necessary energy for grape growth and maturation. Grapes need a proper amount of sunlight for the ability for the plant to make its food, called photosynthesis. If the plant receives low solar radiation during the time of bloom can potentially cause the flower to fail and

The amount of solar radiation observed at any location is the result of the distance from the equator, which causes variations in the length of daylight hours during all four seasons, and additional factors, such as cloud cover, the albedo of the soil surface, and topographic features.
