The ES1759 solar thermal tracking system consists of high performing evacuated solar tubes that unlike fixed panels track the sun from east to west all day long. The tracking system is mounted on a 2 metre tower foundation with a slew drive mechanism that stands alone manoeuvring approximately 15° every hour and returning to a starting position at the end of the day.
The system can be scaled up or down depending on the energy need by the end user.

PRODUCT INSTALLATION AND VARIATIONS
Through significant testing and evaluating in the R&D stage our proposed product that would suit an average household of a family of four and supply the optimal amount of energy would be eight DF120 panels. However, this system can be fitted in any size smaller or larger.
PRODUCT VARIATION - RETROFIT
In a retrofit situation the panels and tracker would be located in the garden space which would require 7m2 of space and can be lowered or installed more elevated depending on the customers preference. All heat pipes and electrical cables would go underground and connect to the buffer tank in a suitably placed position inside the garage or home/business.
The solar thermal system acts as the primary heat source; a boiler, immersion heater or heat pump will then automatically raise the water temperature further if required in the winter months.
PRODUCT VARIATION - NEW BUILD
We are currently working with Birmingham University and a mixture of experts including architects and product design professionals to produce a more aesthetically pleasing product and one that can be integrated into the frame of a house at the planning and building process. We envisage the main pole that holds the solar panels being installed into the structure of the house with the panels hidden to the rear of the house.
One panel can produce 1365 kwh pa in the UK as a static fixed panel. When the 21m2 evacuated tubes are functioning as a tracking system during sunlight hours we estimate 15943 kwh can be achieved per annum in the UK. A saving of 1712 litres of oil per annum.
We have respected that inefficiencies will occur and in the case of a oil run heating system we have incorporated a boiler performing at only 90% in our figures above. This applies to a well insulated 2500sqft house with average family of 2 adults and 2 children.
Current solar thermal systems on the market are only achieving 60% of HOT WATER ONLY and do not contribute to home heating at all! The Terawatt Solar Thermal Tracking System that delivers 85% hot water and 60% of home heating needs per year. In additional to this the system can be applied to air-conditioning units which can replace 100% domestic air-conditioning needs. Solar thermal and air-conditioning is a perfect supply and demand situation where you have plenty of sun in warmer countries and there is a high demand for cooling inside buildings.
