3Suns Residential Solution

The 3Suns Solar Slate roof tile combined with the SolarEdge solar system management components is the first comprehensive  integrated solution to solve all of the challenges encountered with solar PV systems.

Architectural Integration

The 3suns solar slate roof tiles have the PV solar cells integrated into the construction of the toughened roof tile. this key design feature gives the  3Suns solar slate roof tile a stunning modern look on a pitched roof. the 3Suns solar solar roof slate is designed to be a direct replacement for he Eternit Cement fiber roof tile. Installation of the 3Subs solar slate requires no specialized training other than traditional roofing skill.

Increased energy yield compared to the traditional solar system:

  • Very close to 100% coverage of all roof faces with PV solar when utilizing the 3Suns solar slate roof tile.
  • No power loss due to traditional solar panel mismatch which all traditional solar panel systems suffer.
  • Constraint free design allows for 100% utilization of the roof area
  • Easy and cost efficient maintenance for increased up-time of your PV system


  • During Installation: safe string voltage of 1v per group of 50 3Suns solar slate roof tiles until inverter, house connection and grid connection  are commissioned.
  • Maintenance: safe string voltage of 1V per group of 50 3Suns solar slate with an automatic DC shutdown once system is turned off
  • Emergency: safe string voltage with an automatic DC shutdown after grid disconnection or if high temperature detected

Remote Monitoring

  • Ability to monitor the PV system anytime, anywhere in order to guarantee optimal operation
  • Real time Power level monitoring per group of 50 3Suns solar slate roof tiles , real-time alerts of system production and historical performance.

To support small installations, The 3Suns solar system design offers reduced number of 3Suns Solar slate roof tile when used in conjunction  with the Solar edge P405 power optimizers. The minimum number of 3Suns Solar Slate Roof tiles for a single phase AC installation is 300 tiles and 650 tiles for 3phase AC installations.

3Suns Solar Slate Roof  System with Solar Edge StorEdge™ Option
SolarEdge’s StorEdge DC coupled storage solution can be used to increase

energy independence for homeowners by utilizing the Tesla Power Wall battery system to store and supply power as needed. To optimize self-consumption, the battery is automatically charged and discharged to meet consumption needs and reduce the amount of power purchased from the grid. The solution is based on a single inverter for both PV generation and storage. The SolarEdge solar system components offered with all 3Suns Solar Slate Roof tiles  can be connected with out upgrade to the StorEdge solution.

About Us

The idea for 3Suns commenced  in December 2013 after a mid century modernist architectural home came up for sale in Switzerland. It was built in 1967 with Eternit cement fibre roof tiles and was in need of a new solar roof...
