Triple Insulated Solar
This is a packaged product unassembled.
- 70W ETFE Flexible Solar panel 1050mm x 370mm with optimizer placed below the panel.
- UV Stabilized Polycarbonate 16mm thick with 3 sets of open insulation cells, 1,000mm x 370mm
- Polycarbonate has 4 x 12mm routed strips of removed outer polycarbonate skin leaving reservior for Sika 252 application to bond to panel and the caravan/Karavan/Kruiser roof. (Sika is not included)
- Extruded alloy front and trailing edge 370mm x 19mm, either 2 for one panel, if panels are "back to back" then one leading edge per panel plus intermediate polycarbonate piece as joiner under the back to back panels.
- Lightweight at 2.5kg for 70W output (Solar Panel 1.3kg, Triple Insulated olycarbonate 0.9kg, Sika to fix 0.3 kg, Alloy end caps 0.05kg)
- Highest quality Sunpower cells giving a 20%+ yield and 70W from 1050mm x 370mm.
- Top finish is Japanese ETFE with 5 year warranty against de-lamination or peeling.
- Triple insulated with 3 sets of air pockets in a honeycomb UV rated polycarbonate base between the solar panel and roof
- Has concealed optimizer and cabling
- Fitted with an extruded leading edge to prevent driving under overhanging trees damaging front of panel
- Has concealed airspace under for panel wiring to traverse across other panels.
- Isolated panel bonding from roof expansion
How they work:
The Triple Insulated Solar is:
- Lightweight ETFE finished flexible solar panel
- Bonded to a UV rated polycarbonate sheet
- With alloy extruded leading and trailing edges.
- Solar optimizer or connection block is mounted underneath the solar panel and is the same height as the polycarbonate triple insulating material.
- Polycarbonate triple insulating material has four layers with 3 air flow pockets between the top and bottom layer.
- Insulation factor is R3 which means it lets through 1/3 of the heat energy.
- Solar panel on top of the triple insulation layer is cooler and operates more efficiently.
- Triple insulation layer keeps inside caravan temperature cooler in summer and warmer in winter.
- For Kimberley Kruiser, the Tropical roof is kept in tact and there is no reason to replace it.
- For Kimberley Karavan, there is a significant reduction of temperture inside for R3 insulation.
