Designing a solar thermal system

Designing a solar thermal system

When designing a solar thermal system, installers need to factor in the location and orientation of a building, the roof’s inclination, and shading to list just a few considerations. Grant Solar collectors have an absorber (or nett) area of 2.14m² and, it is usually recommended that 1.0-1.3m² of nett should be allowed per person. Then, for the cylinder, they require 50-60 litres capacity per m² of nett collector area. For example, a two collector system will require a cylinder of approximately 200-250 litres and this would be sufficient to satisfy the majority of hot water demand from four people.
