7.Solar on Grid System:

On-grid solar power system is a solar power generation system where it is connected to the utility grid.
The electricity produced by the system is routed to the grid from where it is used to run the various
appliances. The installation of the same is also fuss-free and easy to maintain.

The arrangement of solar modules absorbs the sunlight on them and convert them into electricity. The
current generated here is Direct Current (DC). The solar inverter then converts the DC to Alternating
Current (AC), thus making it power the electrical items. This electricity is then routed to the grid where
it is supplied for day-to-day use. An important feature is a net meter. It is a device that records the energy
supplied to the grid and the energy consumed. At the end of each month, the outstanding is recorded and
the consumer is provided with a bill.

26
8.Solar off – Grid System

An off-grid system is not connected to the electricity grid and therefore requires battery storage.
Off-grid solar systems must be designed appropriately so that they will generate enough power throughout
the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter
when there is generally much less sunlight. The high cost of batteries and off-grid inverters means off-grid
systems are much more expensive than on-grid systems and so are usually only needed in more remote
areas that are far from the electricity grid. However battery costs are reducing rapidly, so there is now a
growing market for off-grid solar battery systems even in cities and towns. Fig of Solar off Grid system.

27
9.Irrigation System:
This article describes the different components of solar irrigation systems, various
specifications, different techniques used, the current scenario in India, the challenges faced by
consumers, and the future scope of solar-powered irrigation systems. Solar-powered water pumping
systems can find application in town water supply, livestock watering, and irrigation. The solar-powered
irrigation system is an application of a solar-powered water pumping system used in paddy fields, and
gardens for watering plants, vegetables, etc. A typical example of a solar-powered irrigation system.

28
 • Advantages of solar irrigation system

• It makes irrigation possible in remote areas

• Is environment friendly
• No grid connection is required
• No electricity bills to be paid
• No fuel is required
• Is durable, requiring minimal maintenance

10.Solar water heater:

The Sun’s rays fall on the collector panel (a component of solar water heating system). A
black absorbing surface (absorber) inside the collectors absorbs solar radiation and transfers the heat energy
to water flowing through it. Heated water is collected in a tank which is insulated to prevent heat loss.
Circulation of water from the tank through the collectors and back to the tank continues automatically due to
thermos siphon system. Based on the collector system, solar water heaters can be of two types: A solar water
heater consists of a collector to collect solar energy and an insulated storage tank to store hot water. The
stored hot water can be used later any time.

11.CONCLUSION
In duration of 30 days of industrial training in Spartan Technologies Limited, I have learnt a lot of things
which cannot be learnt in college campus. In term of theory, I realized that not all the theory part is the
basic for us to know more knowledge but hands-on experience is important as well. In real world there
have plenty of unforeseen factors can be occured. As what we studied in college, most of the theories are
for ideal case, but when come to a real world, it needs to modify and compensate with certain factors so
that the results get are closet to the ideal.

Furthermore, teamwork is one of the important key as well. I got a chance to work as a team with other
people. As what mentioned before, teamwork is very important bacause it can determine the successful of
given tasks. In real world, it is impossible for us to work alone. People might need others helps in order to
complete the tasks. During these 30 days, I work with my leader. While doing a job, a lot of
communications needed between us.

In conclusion, the industrial training program is very good and can create the potential for students to better
quality in the field they want to operate in the present. During the training, I had a taste of how the real
atmosphere in the workplace, as well as good relationship of mutual help and cooperation during my
industrial training.
