Our Technology
Solar air conditioning and solar cooling are currently our main focus in Malta.

We have established an installation and maintenance agreement withHelioDynamics, based in Cambridge, UK. HD has produced the first commercial solar CHP (combined heat & power) system, the HD7.c, as well as the only low-cost medium temperature heat generator, HD7.t.



HD7.c combined heat & power

HD7.c is for organisations which use both power and heat, and provides a cost-cutting alternative to conventional solar solutions and great potential for sustainable economic improvement in less developed countries.

Each module will deliver: 1
500W electricity and 3 kW heat @ 90°C
OR
600W electricity + 2.5kW heat @ 60°C.


A single module consists of multiple flat-mirror facets which track the sun very slowly and very accurately. Sensors automatically monitor the position of the sun through each day, feeding information to the controller for the secure drive mechanism. 2

The mirrors focus the solar rays precisely onto the narrow band of the receiver unit, mounted above the collectors.

The receiver contains high-intensity solar cells, producing electrical power and cooled by water-filled pipes for optimum efficiency. The pipes deliver the heat, @ 60°C - 90°C as required, as hot water, space heating and/or the energy to drive air-conditioning systems.

The system is modular: it can be scaled up to meet changing demand. Up to 8 modules can be driven by a single motor. 3

HD7.c is designed to be mounted on flat roofs. It can also be mounted on poles above a parking lot or on the ground.

The HD7.c meets the most stringent safety and building-code requirements. It is engineered for a 30-year low-maintenance life in aggressive sand, dust and salt environments. The system has a hail-protection system and is designed to resist winds < 210km/h (135mph).

The modular design facilitates repair-by-replacement best practice. Performance and fault-identification of each installation is remotely monitored using telemetry.

HD7.t focussing on heat HD7.t : delivering medium-grade heat < 160°C

A thermal-only system, the HD7.t delivers heat at temperatures up to 160 C. This substantially exceeds the temperature of conventional solar thermal systems and positions the HD7t as a unique system to provide medium-grade heat for both industrial and commercial use. It is particularly suited to driving more efficient and larger solar air-conditioning units.

1 A single module consists of multiple flat-mirror facets mounted on a framework to track the sun very slowly and very accurately. Sensors automatically monitor the position of the sun through each day, feeding information to the controller for the secure drive mechanism.

The solar rays strike the mirror-collectors, which focus them precisely onto the narrow band of the 'receiver' unit, mounted on supports above the collectors.

The receiver contains liquid-filled pipes, which absorb the heat and deliver it for end-use as process heat or the energy to drive more efficient space cooling /air-conditioning) systems. 2

The system is modular: it can be scaled up to meet changing demand. Up to 8 modules can be driven by a single motor.

HD7.t is designed to be mounted on flat roofs. It can also be mounted on poles above a parking lot or on the ground.


3 The HD7.t meets the most stringent safety and building-code requirements. It is low-maintenance and manufactured to ensure reliability and durability. Sealed against sand / dust intrusion into sensitive parts, it also has a hail-protection system and is designed to resist winds < 210km/h (135mph). Each installation is remotely monitored for performance and fault-finding.

The higher temperatures generated by HD7.t allow the heat to be used primarily as process heat for manufacturing, cooling or sanitation.

The payback of the capital cost of HD7 equipment is up to 50% shorter than conventional solar competition. After that, the solar energy comes FREE for 22 - 27 years, the balance of the 30-year design-life of HD Solar systems. Maintenance and service costs are negligible.
