Solar
Tiles

Ingwe Projects and Consulting, in partnership with SolteQ and Marley, provides a service whereby Ingwe takes ownership of all Solar Tile installation wrap around electrical components as well as Electrical Professional Engineer (Elec. Pr.Eng.) signoff on the entire Solar System design, installation and compliance.

Solar technology has advanced significantly to a design where one can move away from the clunky solar panels on top of existing roof tiles to solar systems where the tile itself is a solar tile that replaces the normal roof tiles.

This design is aesthetically very pleasing to the eye. The beauty of the tile system is that there are two design options:

  1. Fully tile your roof with solar tiles,
  2. Integrate the solar tile with either standard Marley Alterna Fibre Cement slate tiles or with Marley’s Modern Concrete Tile, where you would have a part solar, part normal tile depending on your power needs.

There are two options to choose from should one wish to go with a Marley Solar System that is integrated with standard roof tiles, the advantages of each are expressed below:

Advantages of integrating the SolteQ Infinity Slate Solar tile with Marley’s Alterna Fibre Cement Slate tile which will produce a clean modular aesthetic that is elegant and highly efficient.

  • Elegant integrated aesthetic – no unsightly solar panels and exposed wiring, perfectly fits with Marley Alterna Fibre Cement Slates.
  • Maximum and efficient use of any complex roof space – suitable for roofs with complex hips and dormers where traditional solar panels could not be installed.
  • Better performance in shaded and shadow areas – the bi-pass diode ensures that the full tile does not shut down if partially shaded.
  • Supreme durability against extreme weather conditions – meets the requirements of the Swiss Hail Protection Class 3 Standard.
  • Superior strength – Mechanical load of 8,500Pa (=850kg/m2)
  • Light and easy installation
  • Exceptional life-time range and guarantees – 40-year performance guarantee of 80% nominal power. Technical datasheet for all guarantees and terms & conditions can be provided on request.
  • Great return on investment – Increase resell value of your home and initial onset cost may be recouped within 8 years with further savings on electricity costs. Subject to system solution and consumption requirements.
  • Clean source of energy and recyclable – all components of the solar tile is recyclable.

Below are the advantages of integrating with the SolteQ PV Solar Roof Tile with Marley’s Modern Concrete Tile which provides unparalleled efficiency and an elegant alternative to conventional solar panels to suit any complex roof design and circumstance:

  • Unparalleled efficiency when compared to a Standard-PV-Module – due to the light-trap prism glass the Marley SolteQ PV Tile will start generating power earlier in the morning and longer during twilight, whilst a conventional solar panel is still “sleeping” or “shutting down”.
  • Elegant integrated aesthetic – no unsightly solar panels and exposed wiring, perfectly interlocks with Marley Modern Flat Concrete Interlocking Tile.
  • Maximum and efficient use of any complex roof space – suitable for roofs with complex hips and dormers where traditional solar panels could not be installed.
  • Better performance in shaded and shadow areas – the bi-pass diode ensures that the full tile does not shut down if partially shaded.
  • Supreme durability against extreme weather conditions – meets the requirements of the Swiss Hail Protection Class 3 Standard.
  • Superior strength – Capable of withstanding wind load/tensile force of 50kg suction load per tile.
  • Light and easy installation – no additional fastening required with clip-onto-batten system and perfect interlock into Marley Modern Concrete Tile.
  • Exceptional life-time range and guarantees – 40-year performance guarantee of 80% nominal power. Technical datasheet for all guarantees and terms & conditions can be supplied on request.
  • Great return on investment – Increase resell value of your home and initial onset cost may be recouped within 8 years with further savings on electricity costs. Subject to system solution and consumption requirements.
  • Clean source of energy and recyclable – all components of the solar tile is recyclable.
  • Conforms and in some cases, exceeds European standards.

Refurbished 29 KWp Grid Tied System:

Ingwe/E-Power also refurbishes existing systems as was done at a beautiful beach guest house in the Wilderness garden route area who wanted to reduce their carbon footprint.  The guesthouse is now running green. The entire site was refurbished and redesigned by E-Power Technologies, a partner of Ingwe Projects and Consulting.

18 Canadian Solar Panels of 270W were added to the existing system to achieve a total of 29kWp.

Below is what was used to refurbish this system:

  • Solar Panels:
    • Canadian Solar 325W: 75 Panels = 24.375kWp
    • Canadian Solar 270W: 18 Panels = 4.860kWp
    • Total kWp achieved = 29.235kWp
  • Inverters:
    • Inverter 1: Huawei SUN2000 20KTL – 20kW
    • Inverter 2: Huawei SUN2000 8KTL – 8kW
