    Abstract: In periods when greenhouses need heating, heating costs can be reduced if the interior of the greenhouse receives a greater amount of sunlight. For this, the greenhouse surface slope angles need to be increase in such a way that the rays of the sun fall perpendicular to the greenhouse surface in the winter months when they are at a lower angle to t...
