The rapidly changing technology in which solar energy is collected and used in a variety of ways. It's an exciting time in industry with large-scale, powerful solar farms produced heavily from the sun. Even though most of these large-scale technologies are focused at turning energy from suns into electricity, other solar devices are also used other solar products, including a solar-powered cooking grill, are also being designed to create fuel from the air. The capture of solar power in a domestic setting is still limited and we should expect to see some exciting work in the future.
Greenhouses
It is important to note that in a cycle called photosynthesis, plants produce the energy from the suns all the time and process it into food. So, our fields of crops and gardens are one massive solar panel. Through using cold frames and greenhouses, we can absorb more of that energy to lengthen our plant growth and produce more food.
A greenhouse does not raise the energy coming from the suns or focus the incoming light. Under a greenhouse a patch of ground, outside the greenhouse, gets no more lights than a nearby patch. How does a greenhouse work then? Sunlight is not only light-it carries heat energy, too. Once light, like glass, passes through an object it becomes heat. A greenhouse panels catch this heat energy and keep it within the heating system around the roots of the plants and the soil. It is this temperature increase that allows the plants to grow earlier and faster in a greenhouse than plants outside.
A greenhouse requires close joints and glazing in order to maximize the absorption of this thermal energy in order to avoid thermal and warm air from coming in. Glass is not a good insulator but modern thickened glass maintains heat more efficiently when there is no direct sunlight, e.g. when cloud cover is present and during the night.
The use of gaskets in the quality greenhouse manufacturers such as Cultivar frames that not only to allow the greenhouse glazing to expand when it's hot but also ensure a tight fit without air gaps when the glass cools and shrinks the gaskets. The layer of brick or stone at your greenhouse base this will serve as a heat store – the greenhouse will take longer to heat up as these dense materials release their heat overnight.
Sunrooms
You can use the energy from the suns for direct heating of your house. Large windows, sunrooms, and skylights may be added to the house to trap the heat from the suns and reduce or remove electric heating requires. In freezing countries, triple glazing is the best choice if you want to ensure that the heat captured during the day doesn't escape as soon as the sun sets you need to use quality double glazing. In the evenings and overnight the sun room would not be comfortable without standard glazing.
Care should be taken of the Solar Heat Gain Coefficient (SHGC) glasses. This tests about how well the glass transforms into heat the sunlight that falls on it. The scale goes between 0 and 1. The closer the SHGC is to 1 the better it is at generating sunlight heat.
You may of course use some clever architecture to combine the advantages of a greenhouse with a sunroom. Several eco-communities as well as research institutions integrate wide glazed parts to provide ventilation on the side of living quarters as well as a large area for year-round food production.
Walpini Greenhouses
The more away from the equator you are, the less sun you'll feel in winter. There isn't enough sunlight in the winter for many of us to allow us to grow a crop. You can heat your greenhouse artificially, of course-but this is not very effective.
A greenhouse style from Bolivia named Walipini, and has a special design. It is a wide hole (6-8 foot deep) with top level and roof glazed. This architecture has far less glass surface to absorb sunlight, so how does it get warmer in the winter? It uses a secondary heat source-the crust of the Earths! The crust of the Earths is molten metal and magma, and is very hot. To gain from this heat you just have to dig down around 1.2 m. The soil temperature at this depth is relatively stable at 10-16 ° C. This steady temperature is seen all over the globe in most places and even has its own name-The Thermal Constant.
Thus, by digging into the thermal constant sheet, you ensure that the roots of your plants still experience a healthy temperature that makes it possible for winter to grow. It also prevents root temperatures in the Summer from being too high. If you want to try this sort of greenhouse you have to make sure it's a decent 5-foot base above your local water table. This prevents flooding and the root waterlog
