Solar PV systems should generally be installed on the roof and/or open areas which should be a structurally sound area and these areas should be unshaded from adjacent structures, buildings and trees. To obtain the optimum power output, the panels should be installed at a tilting angle facing south.
Solar Performance and Efficiency | Department of Energy
Solar Performance and Efficiency. The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources ...
The system size depends on the number of solar panels and the rated capacity of the panels. System size is measured in kilowatts (kW). One kilowatt (1 kW) = 1000 Watts. For example, a typical home solar system might include 19 x 350 Watt panels, so the system size would be 6,650 Watts or 6.65 kW.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers
