A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity -generating solar panels mounted on the rooftop of a residential or commercial building or structure.
They found that, on average, a green roof-top solar PV system can generate between 1.0 ± 0.4% and 1.3 ± 0.4% more energy per day than a PV system installed on a concrete roof at an average height of 50 cm above the roof surface. In addition, air velocities exceeding 1 m/s may enhance the daily average energy generation by 1 ± 0.4% and 3 ± 0.4%.
As of May 2017, installation of a rooftop solar system costs an average of $20,000. In the past, it had been more expensive. Utility Dive wrote, "For most people, adding a solar system on top of other bills and priorities is a luxury" and "rooftop solar companies by and large cater to the wealthier portions of the American population."
This study presents such an assessment for a grid-connected rooftop solar photovoltaic (RSPV) system located in a tropical climate.
