Up on the roof: Solar power at your plant

Your plant doesn't need a large footprint to begin generating its own energy.

By Dan Hebert

Rooftop solar is impacting the machine- and robot-builder OEM market in multiple manners.

Most of what’s reported about solar power concerns large base-station installations, but this type of facility faces limits due to the huge amounts of land required. The highest power density achieved is around 20 W/m2 in desert solar photovoltaic farms, and conventional power plants often have power densities in excess of 1,000 W/m2, writes Robert Wilson in his article, “The Future of Energy: Why Power Density Matters,” on The Energy Collective.

Given the huge amount of land required for solar, it’s no surprise that it generates less than 1% of worldwide power, writes Matt Ridley in his article, “Fossil Fuels Will Save the World (Really),” on The Wall Street Journal online.
