Choose the technology that works for you

Solar hot water has come a long way in the last decade, particularly with the introduction of evacuated tube collectors (ETC) that are rapidly becoming the preferred option. Flat plate systems (FPC) are ideal for pressurized solutions while ETC systems are cost-effective when you don’t need extra pressure.

Most Cost Effective Solution

Evacuated glass Tube Collectors (ETC)


For ETC systems, Orb uses large diameter '3-target' glass tubes that heat water from 25 to 65 degrees centigrade typically in just 4-5 hours on a sunny day.

Orb’s ETC systems come with ceramic coated tanks that are insulated with high density polyurethane foam for better heat retention.

Premium System for Pressurized Solution

Flat copper Plate Collectors (FPC)


Orb’s flat plate collector systems are rugged and reliable, and are built to support high pressure applications (up to 5-bar).


add a heat pump for 24/7 hot water

Heat pumps are also a cost effective way of heating water. Orb integrates heat pumps with solar water heating systems for 24/7 hot water.

Heat pumps range from 100 LPH up to 500 LPH and can be integrated with any solar water heating system.
