Solar heating influences improved growth of greenhouse vegetation. The Roman era noticed the introduction of greenhouses, and these exist to this day, many modern European greenhouses having been constructed in the 16th century. A synopsis of modern day horticulture would not be complete without them. Uncanny strategies of optimising the employment of electrical power supplied by the sun are still in use. Updating the synthetic lighting, the sun is used to light up the inside of the greenhouse. Energy usage for lighting may be decreased by 25% throught the proper implementation of these types of daylight systems. Usually in these systems you would come across a light shelf and a light tube, saw-tooth roofs together with skyllights.
Water distillation can be done with solar power, and salt water turned into drinking water. Solar water disinfection, or SODIS, is the course of action whereby water is made fit for consuming, using plastic polyethylene terepthalate bottles that are filled up with the impure water. This is a system that varies depending on environmental conditions, and it can take a very long time. When the conditions are over cast, it will take two days, and even with good conditions it takes no less than 6 hours. In developing countries, there are currently two million people getting their daily drinking water implementing SODIS.
Photovoltaic or PV can be put to use to convert sunlight directly into electricity. It has been implemented a great deal for powering items that are minimal to medium in size. A calculator which is powered by a single solar cell is an example of this. Photovoltaic has furthermore been used to generate electrical energy for homes. The manner in which solar energy is used probably the most is for heating water and in addition the rooms in a house. Solar air heating, and likewise ventilation, is becoming more prevalent. The most widely implemented of the three popular methods for making use of solar energy is solar cells. They turn light which falls on them straight into electricity, and are generally referred to as photovoltaic (or photoelectric) cells.
Using a huge array of mirrors, solar furnaces can easily produce genuinely high temperatures. They are also known as solar cookers, and they are designed to cook food in hot countries. Great as it is, solar power does have a small number of downsides, though. During the night it doesn't operate, and it can be expensive to set up, but once the solar energy is accumulated the benefits are worth it.
