WHICH SIZE SOLAR PANEL HOT WATER HEATING SYSTEM
IS RIGHT FOR ME?

This guide will help you assess the right number of solar panel hot water heating panels for your property. Note that all properties vary depending upon their geographic location and situation.

An unshaded south-facing roof is ideal for a solar system. Other unshaded southerly orientations also work well. Where there are larger deviations from the south an increase in collector size will compensate for any loss of directional efficiency.

Typically 6 sq m of solar collectors for hot water support are sufficient for an average single family house. Over the year up to 60% of the average domestic hot water requirement can be achieved by a solar system with this size of collector.

A simple guide is: up to 1.5 sq m of solar collector area / person

For example, a family house (4 persons) with average consumption of hot water, roof pitch: 40°, roof orientation: 30° to the west: 4 x 1.5 = 6 m² collector area

Or in solar panel terms...

ONE SOLAR PANEL
1-2 person household with one bathroom

TWO SOLAR PANELS
3-4 person household with one bathroom

THREE SOLAR PANELS
3-5 person household with two bathrooms
