The Spare Flat Plate Collector is a premium solar energy component designed to replace or upgrade the heat-absorbing module of existing solar water heater systems. Built with high-performance materials and engineered for long-lasting efficiency, this collector is a key component in maximizing solar thermal energy capture for domestic, commercial, or industrial applications.

At its core is a selectively coated copper absorber plate that efficiently converts solar radiation into thermal energy. The collector is housed within a weather-resistant aluminum or galvanized steel frame, sealed with low-iron tempered solar glass to ensure high solar transmittance while withstanding environmental wear like hail, UV rays, and moisture.

The internal piping — typically constructed of copper riser tubes ultrasonically welded to the absorber sheet — provides uniform heat transfer to the water or heat transfer fluid. Integrated with a high-density mineral wool or polyurethane insulation backing, this collector minimizes heat loss, maintaining high thermal efficiency even in colder or windy climates.

Compatible with most direct or indirect pressurized solar water heating systems, the Spare Flat Plate Collector is ideal for replacing damaged or outdated collectors, scaling up existing systems, or incorporating into new installations requiring efficient and environmentally friendly hot water solutions.
