● Sunlight hits the flat panel collector.
● Water in the collector heats up.
● Hot water rises to the insulated storage tank.
● Cold water enters the collector, cycle continues.
● Absorber plate – metal plate with a dark coating that absorbs sunlight.
● Transparent cover (glazing) – glass that lets sunlight in and reduces heat loss.
● Insulation – at back and sides to prevent heat loss.
● Pipes/headers – carry the heat transfer fluid.
● Casing/frame – protects the collector.
It works by absorbing sunlight, heating the fluid in pipes, and minimizing heat loss.
● High efficiency in sunny climates.
● Durable and low maintenance.
● Strong water flow for showers and taps.
● Cost-effective.
● No electricity required for circulation.
● Performance drops in cloudy weather.
● Electric booster may be needed for cold days.
● Requires sufficient roof space (~2 m²).
● Installation & Use Cases:
● Residential homes, guesthouses, offices.
● Retrofitting existing plumbing.
● Regions with high annual solar insolation.

For Region with heavy limestone and hard water… will strongly recommend install a pre-water filter for your water heaters
Main function of the pre-water filter:
● Remove calcium carbonate (limescale) and mineral sediments from hard water
● Reduce scale buildup inside solar water heaters, pipes, and heating elements
● Protect the inner tank and heat exchanger from corrosion and blockage
● Extend system lifespan and maintain stable heating efficiency
● Improve water quality for safer and cleaner hot water use
Middle East, Africa…
A: Common capacities include 150L, 200L, and 300L, suitable for households, hotels, and small commercial projects.
A: High-quality models use stainless steel or enamel-coated tanks with thick insulation to ensure durability and long heat retention.
A: Very little. Periodic inspection and basic cleaning are usually sufficient to keep the system running efficiently.
A: Yes. Integrated flat plate systems are designed for quick installation and do not require a pump, reducing installation time and cost.
