One advantage is that all modules produced at the facility are compliant for procurement in American Recovery and Reinvestment Act (ARRA) projects.
Parallel Solar Technology
02/01/11 - Michael Lamb
Our Parallel Solar approach handles voltage management at the module level, using a DC-to-DC converter (the vBoost) to boost each module’s output. So the array has a high-voltage bus that will never exceed its set voltage as it feeds the central inverter. This allows you to connect the modules in parallel rather than series.
The PV Solar Shutter is a perfect fit because it requires no roof space and no large battery banks, and is very easy to install and uninstall. Each unit can purchase its own shutters, have its own power source, and offset usage one window at a time. Even renters can, like any other window covering, take their shutters with them if when they move.
