The PV Solar Shutter from Plug ’n Save Energy Products is a custom-designed, power-producing window shutter that allows homeowners to create their own energy on a smaller scale. Set in louvers, photovoltaic cells collect power from the sun and, using grid-tie inverter technology, channel it directly into a building’s electrical system. The shutters are portable and install in the same way as a conventional window covering. They are suited for retrofits and buildings otherwise unable to support solar power, including condos, apartments, and office buildings.
