ES solar roof

Solar collector and roof combined

Great Notley Discovery Centre, Essex (photo  Sue Barr)

The ES Solar Roof turns a roof into an efficient solar collector for hot water, space heating or swimming pool heating supplying between 300 & 600kWh/m² energy per year. It simply replaces the tiles, slates or other roof coverings with a series of unglazed collector plates connected by sealed joints. The ES Solar Roof can be installed on both low pitched and curved roofs, allowing great architectural design flexibility.

  • The ES Solar Roof is simple and fast to install
  • It fulfills all the requirements of a standard roof
  • It is aesthetically appealing
  • Strong, durable and high quality materials
  • Lightweight construction
  • Highly efficient - Performance exceptional at low pitches, the same at 5° as at 30°
  • Less expensive than glazed solar panels
  • For domestic, commercial and industrial buildings

The ES Solar Roof is an attractive alternative to more conventional discrete solar panels and turns the whole roof into a solar collector. It integrates renewable energy into the architecture of a building -harvesting between 300 and 600kWh/m² of thermal energy per year and so reducing the burden of Climate Change levies.

While being less efficient than glazed solar panels for high temperatures, the capital cost is also much lower, and so for many applications this solution may be preferable. It is ideal where a larger roof area for solar collection is available and especially at low roof pitches.

The ES absorber is made of two sheets of high quality stainless steel, ensuring a long lifetime. A water and anti-freeze mixture flows between the two sheets, irrigating the whole sheet area. Due to the absorber’s pattern of offset metal pads the liquid flows turbulently resulting in excellent heat transfer.

The dimpled surface of the absorber is covered with a durable black coating that converts solar radiation into heat very efficiently, but does not re-radiate the heat. The heat can be applied to any form of domestic, commercial and process use including hot water, swimming pool or even space heating.

The fact that the ES Solar Roof can be curved gives great architectural design freedom. The flexible system allows for installations ranging from 20 to 1000m² and more.
