Summary Draft 2

  The Economic Times’ article on “What are solar light panels and how do they work”(2019) informs readers about the purpose, features, and applications of solar light panels. The Economic Times states that “solar light panels are used for residential and commercial lighting purposes” and that the panels are made of "photovoltaic (PV) modules." The modules are composed of solar cells and these solar cells are made using crystalline silicon. These cells will draw in energy from the sun and convert it to electrical energy for power usage Economic Times(2019). In the system, there are cells that are "either connected or not connected to the main power grid ". When the system is linked to the power grid, DC (Direct Current) power is generated through the PV panels through a power conditioning unit to create AC(Alternating Current) Power Economic Times(2019). Power developed during daytime is used for "lighting systems." Some of the features of the solar light panels include it being durable and that the "individual solar cells are semiconductors and can produce electricity on their own." Benefits of the solar powered system include the reduction for the use of limited resources and that these cells do not produce harmful greenhouse gasses Economic Times(2019). According to the article, solar light panels can be found in households to reduce cost and cut down global warming issues. They are also used in everyday gadgets like our "calculators, watches, torches, and flashlights." As Singapore has very little land space, they should adopt to use Passivated Emitter and Rear Cell(PERC) panels as it has the highest efficiency compared to the rest.
