Light-Guide Solar Optic

Light-Guide Solar Optic (LSO)--is a new type of solar concentrator that could significantly lower the cost of generating electricity from the sun. Unlike existing designs, there's no need for mirrors, complex optics, or chemicals to trap and manipulate the light. "It's pure geometric optics," says Nicolas Morgan, director of business development at Toronto-based Morgan Solar. LSO is a flat, thin acrylic optic that traps light and guides it toward its center. Embedded in the center of Morgan Solar's concentrator is a secondary, round optic made of glass. With a flat bottom and convex, mirrored top, the optic receives the incoming barrage of light at a concentration of about 50 suns and amplifies it to nearly 1,000 suns before bending the light through a 90-degree angle.

IMO Precision Controls - Keeping Solar Safe

The IMO FireRaptor provides three forms of Solar Panel Rapid Shutdown to ZERO VOLTS in case of fire or other emergency: Manual Panel Shutdown to 0V Operated from Ground Level, Automatic Panel Shutdown to 0V at >85°C (185°F) Temperature, and an automatic Panel Shutdown to 0V on External Power Loss. The FireRaptor can be installed without any set-up and with any string inverter as its functionality is completely independent. "Plug & Play" style installation using industry standard connectors is easy, whether fitted to new installs or retrofitted to existing projects to upgrade fire safety functionality. Meeting NEC2017's regulation to switch DC current at the PV panel in under 30 seconds, FireRaptor is remains one of the safest and most effective means of isolating DC current at the source, and the only rapid shutdown with a 20 year warranty.
