How do we define solar energy from the roof and what exactly is a roof the top of solar systems?

Solar energy is the energy that comes by radiant sunlight and heat from the sun, which generates solar thermal energy and electricity that includes water heating and solar architecture. Solar radiation, in conjunction with other sources of solar energy are the most readily available source of renewable energy.

Solar technologies mostly comprise of active energy or passive energy based on the way sunlight is absorbed, converted, and distributed.Active solar technologies refer to photovoltaic modules (also known as photovoltaic panels) as well as solar thermal collectors which transform sunlight into productive outputs. Active solar technology boosts energy production and is considered an alternative technology, while passive solar technology lessens the requirement for other resources and is typically considered to be as a demand-side technology.Passive solar technologies are:

• Buildings are orientated towards the sun.
• The selection of suitable thermal mass materials or properties for light dispersion.
• Spaces that naturally allow air to circulate.

Rooftop solar energy system also referred to as rooftop PV systems is an photovoltaic (PV) system that includes solar panels that produce electricity and are positioned on the roofs of structures, whether they are commercial or civil structures. A solar power system comprises of photovoltaic panels and mounting systems as well as solar inverters, cables as well as other electrical equipment. Rooftop solar panels are usually tiny compared to ground-based power stations.

The majority of roof-mounted PV systems are grid-based systems. The PV systems installed on homes generally are able to handle that range from 5 to 20 Kilowatts (kW) in comparison to commercial buildings generally can be found between 100 kilowatts to one megawatt (MW).

A rooftop photovoltaic system is one that has its electricity-producing solar panels mounted on the roof of a home or other building. Photovoltaic modules as well as cables, mounting systems solar inverters, cables, and other electrical components are a few of the components that make up the system. When compared to photovoltaic power stations which are mounted on ground and are able to operate of up to megawatts rooftop-mounted systems are smaller.
