Solar photovoltaic power generation is becoming increasingly cost effective. It is useful to understand the essential parameters if you are looking to achieve the associated benefits into either a new scheme or to consider retrofit programmes.
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."
The roof-mounted solar PV is installed at the optimum angle for each latitude and is sun-facing and shade-free to generate maximum electricity output. The building rooftops are flat in design leading to the utilization of the entire rooftop for the installation of solar panels.
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.
In practice, SC and SS can be from a few percent to theoretically 100%, depending on the capacity of the photovoltaic system and the user load profile. The question of the ratio of own consumption is deeply connected with the question of whether to invest in the installation of a roof PV system or not.
To install 1 kWp of roof-mounted solar PV, 10 m 2 of rooftop area is required, which is in line with the thin film technology currently in use. The roof-mounted solar PV is installed at the optimum angle for each latitude and is sun-facing and shade-free to generate maximum electricity output.
Under the moderate scenario, it is possible to install up to 570 GW roof photovoltaic capacity by 2030, which is a big step forward since installed 137 GW in 2020 [ 1 ]. Solar PV power plants on buildings in the EU could produce between 680 TWh and 1300 TWh.
