We harness the Solar energy, for you

Alubond solar collector panel (SCP) is a unique worldwide patented composite panel, sandwiching a high durable exterior grade core between two layers of aluminium skin. The Alubond SCP's are light weight, features phenomenal flatness which retain its shape and comes with low cost maintenance. This translates into easier handling,packaging and shipping.

Alubond SCP's are designed for minimum support structure assembly thereby maximizing ease of installation and fabrication which results in cost savings for total assembly of solar units such as solar troughs or suntrof.

Alubond SCP's has the best reflectance, corrosion and weather resistance, longevity, adhesion properties and highest warranty terms in its class thus making Alubond solar collector panels the world’s best solar reflective panels available today.

The Earth gets 1021 Joules of Energy every day from the sun. The sun gives out 1000 watts of energy to every square meter of the earth’s surface. The energy we receive from the sun in 1 second is 1000 times greater than the worlds energy needs, in one year.

Solar energy is 100% clean, Non polluting, always available free of charge, that significantly reduces energy costs.

Reasons which make it clear why Alubond Solar Collector Panel is the world's leading solution for the optimum usage of solar reflectance.
