Solar Greenhouse Systems | Types and Benefits
Today, solar panels are equipped with a variety of technologies, each of which operates differently. However, we will focus on the operation of solar panel technology in greenhouses. Alternatively, photovoltaic technology.
Solar panels are devices that convert solar energy into electrical current via photovoltaic cells. Contrary to popular belief, they do not require a magnificent radiant sun to generate energy. Solar panels can generate electricity on cloudy days because they do not require direct sunlight.
Are they suitable for greenhouse use?
Greenhouses are excellent for retaining heat and warming the surrounding environment.
Gardening is a wonderful pastime that can be enjoyed all year long if you have a greenhouse. However, these can consume a significant amount of energy when it comes to maintaining optimal temperatures and operating the various devices and pumps contained within. Recently, an increasing number of people in the gardening community have invested in solar panels for their greenhouses, thereby reducing their environmental impact and ensuring the happiness and health of their plants.
Solar Greenhouse System Types
Solar panels of virtually any type can be used in greenhouses. The primary solar panel materials are silicon-based and range in efficiency and price. Here are the two types, along with some additional information about each.
Solar Active Greenhouse System
An active solar greenhouse system harnesses the sun’s energy and converts it to electrical energy. External devices such as radiators, water pumps, and fans are used to collect, store, and circulate energy. Solar energy cannot be used to heat a greenhouse without these devices.
Flat-plate photovoltaic (PV) panels serve as the solar collectors in an active solar system. These panels are stable and immobile devices that collect and convert energy via liquid and air. Hydronic collectors use liquid, while air collectors use air.
One of the advantages of a solar greenhouse system is that it is not entirely reliant on the sun, as energy is stored externally. Apart from that, it is completely silent, and the panel’s heating keeps it clean in any weather condition.
Solar Passive Greenhouse System
In contrast to an active solar greenhouse, a passive solar greenhouse does not rely on external devices. However, this is dependent on the greenhouse’s structure and construction. The solar energy is stored in thermal mass, which is an object that retains heat, such as rocks, concrete walls and floors, and water tanks.
The passive solar system’s concept is that it insulates the greenhouse during the night to keep it warm. The advantage of this type of system is that the thermal mass heats up quickly but cools down slowly.
The Benefits of Solar Greenhouses
- They are rather simple to install. They assist you in creating and maintaining a steadily warm temperature while adding no heat to the space.
- You can save money on heating and maintain an appropriate temperature in your greenhouse.
- Maintains itself with minimal to no effort
The following are some methods for increasing the effectiveness of your greenhouse solar system:
- Ascertain that the panels face south.
- Ascertain that they are properly positioned to gather sunlight. Ascertain that your greenhouse is adequately insulated.
- Ascertain that the panels are not obscured by shade.
