Solar Energy For a Better Future

Solar PV modules were originally introduced in the 1950s - can you believe it? Yes, they have really been around that long. However, they were inefficient and expensive, so they remained unpopular. Only in recent years has the cost of solar power become feasible for large-scale industrial, commercial and domestic use. This has happened because solar power modules have evolved multiple times. There are now three main types: monocrystalline, polycrystalline and thin-film. Each type has its own pros and cons. PV Cells: A brief history In any type of solar cell, silicon crystals generate electric current after absorbing sunlight. This process is the photovoltaic effect. Monocrystalline technology has been around for the longest time, but is facing competition from polycrystalline and thin-film technology. Depending on the end consumer’s budget, local laws and availability of land / sunlight hours, the solar module installer will choose one of these three technologies. Mo...
