Solar energy can be used to heat your pool, heat water, heat your home, charge batteries, turn on street lights and lamps, and even produce energy for your entire home . But the companies didn't stop there. Mini solar panels can also be found inside calculators, cell phones, DC motors, laptop chargers, cars, and even military equipment. But what are the most common uses? “Many of the most common, useful and economical solar energy applications are passive in nature and do not involve any conversion to electricity. Many homes, for example, are built with the position of the sun at various times of the day in mind, ensuring that the home receives plenty of natural lighting. Various architectural considerations can also ensure that buildings remain at reasonable temperatures. Another of the common applications of solar energy of this form can be seen in greenhouses. The sun passes through the transparent enclosure of the greenhouse and warms the plants and soil, creating warm air that cannot escape from the enclosure and thus providing a good environment for plant growth” (Daniel Liden). With this in mind, how would you like to use solar energy?
