What is PV?
Solar cells, also called photovoltaic (PV) cells by scientists, convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect.
How many solar panels do I need to install on my rooftop?
The number of panels that need to be installed depend on the energy consumption levels of the user. Higher the consumption of the user, higher will be number of panels required to be installed, keeping in mind the size of roof and the availability of direct sunlight.
I have trees/ buildings in the neighbourhood which block direct sunlight. Can I install a solar rooftop system?
Any neighbouring buildings/ towers/ advertising boards/ water tanks/ etc., which block direct sunlight from falling onto the solar panels will reduce the electricity generation. Any kind of shading reduces the output of the solar panels.
How long will the solar panels last?
A PV system that is designed, installed, and maintained well will operate for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 25 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly. Experience has shown that most problems occur because of poor system installation.
Can I use PV to power my residential home?
PV can be used to power your entire home’s electrical systems, including lights, cooling systems, and appliances. PV systems today can be blended easily into homes. The most common practice is to mount modules onto a south-facing roof or wall.
How do I use solar PV for my business?
PV systems can be blended into virtually every conceivable structure for commercial buildings. You will find PV being used outdoors for security lighting as well as in structures that serve as covers for parking lots and bus shelters, generating power at the same time.
What is net-metering?
Net metering is a policy that allows homeowners to receive the full retail value for the electricity that their solar energy system produces. The term net metering refers to the method of accounting for the photovoltaic (PV) system’s electricity production. Net metering allows homeowners with PV systems to use any excess electricity they produce to offset their electric bill. As the homeowner’s PV system produces electricity, the kilowatts are first used for any electric appliances in the home. If the PV system produces more electricity than the homeowner needs, the extra kilowatts are fed into the utility grid. Net-metering benefits are available if they are allowed by the rules and regulations pertaining to the State you reside in.
What is Drip Irrigation?
Drip irrigation is the slow and precise application of water directly to the roots of the plant, resulting in less water lost to evaporation in the sun or wind. The root zone is maintained at the optimum moisture level combining the proper balance of water and air. All of these factors promote deeper penetration of the roots, higher foliage growth and increased flower, vegetable and fruit production.
Why use Drip Irrigation?
Drip Irrigation applies water and nutrients directly to the plant’s roots and only where it is needed to ensure healthy growth. Studies on drip irrigation have shown results of up to 60% more efficiency over sprinkler systems.
Where to use Drip Irrigation?
It can also be installed in a greenhouse and nurseries. They are also ideal for installation on difficult terrain such as on slopes. Drip irrigation can be used on shrubs, groundcovers, trees, flower beds, vegetable gardens, perennials, pots and containers.
What is a Greenhouse?
Greenhouse is a structure made of polycarbonate/ plastic sheets and has a metal frame. It used by farmers and gardeners to grow plants. It allows for greater control over the growing environment of plants. Factors that can be controlled by use of a greenhouse are temperature, level of light and shade, irrigation, fertilizer applications and humidity levels.
What is the importance of Greenhouse ventilation?
For a greenhouse to be successful, ventilation is the most important element. Without proper ventilation, growing plants in a warehouse can become a problem. The need for ventilation is to regulate the temperature and humidity to the optimum level, and to ensure movement of air. This ensure fresh supply of air of photosynthesis and plant respiration and may enable pollination. Ventilation can be controlled through vents and fan systems.
What is advantage of using a Greenhouse to a farmer?
Greenhouses give farmers the advantage of growing crops that are not suitable for growing in their region due to unfavourable climatic conditions.
