Optimizing the Inclination of Solar Panels Taking Energy Demands into Consideration
Abstract
Ideally, the angle of inclination of non-tracking solar panels, whether of the photovoltaic variety or solar thermal, should be determined in relation to the energy demand curve they are meant to satisfy. This is not always the case since it is common practice to install solar panels at a particular angle, depending on the geographical location of the site, irrespective of the demand curve. For example in Malta, installers have for many years been fixing panels for solar water heating at an angle of inclination of 45 degrees to the horizontal, since Malta is situated at a latitude of 36 degrees North.
