Solar row stacks get some-more out of sun

LoginRegister@indiatimesLoginRegister@indiatimes In nonetheless another arrangement of Gujarati ‘jugaad’, a group of scientists from Gandhinagar-based Gujarat Energy Research and Management Institute (GERMI) has designed solar panels that can be built one on tip of a other. These solar row stacks occupy many reduction space though collect some-more of a sun’s energy.

The GERMI group showed how stacking adult photovoltaic (PV) cells (or solar panels) creates them adult to 90% some-more fit for harvesting and generating energy but carrying to use outrageous plots of land to widespread out a panels.

The group led by GERMI executive Prof T Harinarayana and Pragya Sharma simply built dual solar panels, one on tip of a other and distant by a stretch of 3m, 5m and afterwards by 10m. The thought was to discharge a problem of shade expel on a bottom row by a solar row on tip during a following time durations in a day — from 9am to 12pm; 12pm to 3pm; and 3pm to 5pm.

The team’s ‘jugaad’ lay in attaching a complement of mirrors to a solar row smoke-stack so that a former reflected object directly on to those tools of a bottom solar row that did not get light between 12pm and 5pm. With such an arrangement, a energy outlay on a standard day in Gandhinagar increasing to 479kWh with a two-layer solar row stack. In a space assigned by this stack, a 756sqm widespread of solar panels could furnish customarily 252kWh power.

“The stretch between dual solar panels works best if a stretch is 5 meters. The tallness should be practiced after detecting breeze pressure.Such stacks would be useful for rooftop solar energy generation, quite on tip of apartments where space is customarily limited. Right now, a counterpart system’s transformation is mechanical. The modernized chronicle will use sensors and automatically adjust mirrors,” pronounced Harinarayana.
