Orb manufactures solar water heating systems for better quality. Orb’s ceramic coated storage tanks are the most reliable in the Indian industry - with incidence of leakage just 0.5%. Orb offers both evacuated glass tube technology (ETC) and copper flat plate technology (FPC) and provides 3-free preventive maintenance visits, and a 5-year warranty.
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. Both systems will deliver between 2-4 year payback.
For ETC systems, Orb uses large diameter '3-target' glass tubes that heat water from 25 to 65 degrees centigrade in just 4-5 hours on a sunny day in India.
Orb’s ETC systems come with ceramic coated tanks that are insulated with high density polyurethane foam for better heat retention.
