Solar panels can supply over half your hot water, saving 50-60% of your annual water heating bill.

The panels are most effective between the months of May and September and work even on a cloudy day. The best position for the panels is facing south (within 30 degrees in either direction) and a roof slope of between 25 and 70 degrees. Having said this, panels pointing within 70 degrees of south on a roof slope of between 10 and 90 degrees can still achieve 90% efficiency.

Solar panels can be used with existing heating systems, or for best results, matched components such as a dual-mode hot water cylinder and system controller can be purchased from Click On Solar.
