Next-generation alternatives
Published in Peter M. Schwarz, Energy Economics, 2023
Sunlight causes a chemical reaction that converts photons—particles of light—into electrons of DC, and an inverter converts the power to AC, the current used in power grids.1 This source of electricity is only available during daylight hours at times when clouds or even trees do not obscure the sun. Typically, households with rooftop solar make use of energy from the grid, with the option of substituting solar energy when it is available or even selling electricity back to the grid when they use less than the available solar energy.

The rooftop solar panels installed in a residential area can be mainly used as solar electricity and heating the water at individual or bulk level as heating of pools, etc. Solar energy can be used to charge the batteries that may be utilized in the absence of sunlight or grid supply for residential loads. Moreover, solar energy can also be used in remotely located load/islanded systems such as remote villages and hospitals.

Chapter 26 of ASCE 7-16 defines “Rooftop Solar Panels” as a device to receive solar radiation and convert it into electricity or heat energy. Typically, this is a photovoltaic module or solar thermal panel. “Solar Array” is any number of rooftop solar panels grouped together.

In many urban areas, rooftop solar systems have been installed recently on government buildings, private institutions and residential buildings and the power generated is utilised for own consumption and the surplus power if any is fed to the grid. The significant fall in the cost of solar modules since 2012 encouraged individuals and entrepreneurs to install solar photovoltaic power systems for the generation of electricity either for their own consumption or selling to grid. Also this led to the formation of joint ventures between Solar Energy Corporation of India Ltd (SECI) and different state governments (Padmanathan et al. 2017). The global solar power capacity has increased from 6 GW in 2006 to 505 GW in 2018, and China continues to be the leader of solar energy (45%), while India’s contribution is 6% (Figures 1 and 2) REN 21, R. (2019). Installation of solar PV systems on the rooftop of individual houses, institutional and commercial buildings for electricity generation is seen in many places across the globe. Besides this, mounting solar modules on sides of buildings, windows, skylights and rooftops for the generation of electricity as well as giving the building an aesthetic view are gaining its momentum throughout the world. PV modules can be mounted on the building envelops of existing structures, or design provisions are made for mounting PV modules in newly constructed structures. BIPV not only generates electricity but also provides heat to the building and provides thermal and other weather protection and shading.
