One kilowatt is about what it takes to heat up some leftovers in a microwave — or to power the largest and most technically advanced telescope ever built. Thanks to its solar array, NASA’s James Webb Space Telescope will stay energy-efficient more than 1 million miles (1.5 million kilometers) from Earth. American engineers at [...]
Seems unrealistic, right? After all, it is one of the biggest drawbacks of solar energy. But thanks to science & engineering, it is well within your reach. At night the lack of sunlight cannot generate electricity - a disadvantage for solar energy. However, what if they worked at night? That’s no joke, according to [...]
Solar Panels made up of crystalline silicon are dominating the global PV market. As the output power of a single solar cell is not enough to meet the actual needs, several silicon solar cells are placed in parallel connection to make up a PV module. A hot spot describes an over proportional heating of [...]
Coal and fossil fuels are cheaper; that is why a big portion of energy comes from these sources today. Although it was expensive at one time, the falling prices of solar and wind over the past decade had changed the game. Seems exaggerated but the cost has dropped more than 80%. Just 10 years ago, [...]
