Solar Greenhouses
All About Solar Greenhouses
Greenhouses come in a wide array of styles, types and materials. Today, people are becoming more
environmentally friendly, by investing more in solar panels and energy. You will find that you can cut costs by
investing in solar greenhouses. These can be a worthwhile investment, since depend on a number of crops you grow
for food.
What is a Solar Greenhouse?
A solar greenhouse is described as a structure that houses plants and collects solar energy.
Solar greenhouses have a specific purpose. It can store heat, utilizing this during the night when the temperature
is lower. The heat can work well during winter, cloudy days and the cold season. You can provided the required
temperature to the plants to sustain growth even during the cold months. The good thing about solar greenhouse
setups is that you have several options that suit your specific needs.
The Types
Solar greenhouses can stand independently. These are ideal for large production setups. The
freestanding ones are excellent for commercial production. These can produce crops like herbs, vegetables, fruits
and ornamental flowers. These usually appear in a couple of main designs namely the Quonset type and the shed
type.
The Quonset type is described as a low-cost greenhouse. It appears like a underground pit with a
tunnel and a Quonset-shaped frame. The setup has one or two layers of plastic film. This type can save you as much
as 40% of heating fuel. The shed type incorporates a very long axis that runs from the east towards the west. There
is a wall facing south glazed to gather the maximum level of energy from the sun. The wall facing to the north is
insulated to prevent loss of heat. The features help you determine the difference between a solar greenhouse from a
traditional version.
More on the Types
Solar greenhouses can be connected to the house if you choose the lean-to type. The attached
solar greenhouse can be described as the structures that create some room that sticks out from the house. These are
very good for growing herbs and transplants. The solar greenhouse
can be classified as either
passive or active. Either type uses various resources, but serves a universal purpose. Some places have longer cold
months, so individuals have to rely on passive solar greenhouses, via an electric heating system or gas.
The plants can therefore be protected from the cold longer. You can maintain good production
rates, regardless of the weather conditions. The use of heating systems of the setup can be very affordable and can
be used optimally if there are crops of high value to be produced. The active setup uses supplemental energy, by
transferring the solar heated air from the storage space to the other regions of the greenhouse.
About the Design
Managing and keeping a regular greenhouse does not change much compared to the solar greenhouse.
There are some features that matter, though. Solar greenhouses have oriented glazing to receive the highest solar
heat, especially during winter. The materials are made to reduce heat loss. Heat storing materials are used. There
is extra insulation when sunlight is absent. The solar greenhouse relies heavily on natural ventilation to cool the
plants during extra hot days and the summer.
Where Heat is Stored
The solar heat storage is the major feature when you design the solar greenhouse. There should
be enough solar heat stored to keep it warm even during cold nights. The basic method used to keep the energy is to
place concrete and rocks directly in the sunlight to keep the heat. Cinder block walls located at the north end of
the greenhouse can be used to store heat. Dark-colored ceramic floors can be used to keep the heat. Flooring and
walls not used for heat absorption needs to be colored lightly. This is done so that heat is reflected and light is
properly distributed to all the plants.
Proper Management
The amount of heat stored can be determined by the proper management of the greenhouse. The
greenhouse full of structures and plants can keep heat easily. Composts can help the heat storage objectives, since
these create carbon dioxide within the atmosphere. The microorganisms in the compost give enhancements in plant
production.
