Average output: 1200 kWh at constant 50 degrees C
Extreme performance:
Our solar panels can generate over 1 million watts of thermal energy per year, per panel.
This figure is the result of a complicated model that takes simulated data of local weather to calculate performance of the panels.
The Firman Solar panel is a vertically mounted glazed collector without collection pipes, intended for systems equipped with circulating pumps.
The solar panels have an integrated connection system enabling pressure sealed linkage with adjacent panels. The Firman Solar panel is constructed with a single meander system piping without using soldering or welding and is folded into the absorber plate; a single piece tray is folded into the frame holding the glazing.
Maintenance:
The Firman Solar panel does not require any maintenance. The panels have been designed to withstand high temperatures; the glass does not require cleaning. There are no user serviceable parts inside and due to the heat exchange process the panel does not contact potable water or water to be heated.
Construction:
Stamped Al-Mg sheet absorber fins with a selective coating conversion layer span the copper pipe meander. The flanged connection pipes are connected to the hydraulic circuit by patented connection clamps. The collectors can be connected in parallel, up to 10 panels per row.
