There are many challenges in the society, one of them are frequent power cut-off and high electricity bills. In India the demand of electricity per head is more than the generation of electricity. With the growing population the demand is also increasing. However generation of electricity is not increasing at that pace as we are still dependent on non-renewable resources.

To resolve the problem of frequent electricity cut-off and dreaded electricity bill we should switch over to the solar energy. When we visited solar manufacturing sites and suppliers and also local residents who are using solar panels we got to know that most of them are using rigid solar panels. Many questions came to our mind such as what will happen at that time when sun rays are not perpendicular to the solar panel, what will happen to the solar panel if there will be hailstorm and many more After a brainstorming session and lot of research we came to the conclusion of making dual axis solar tracker along with rain sensor to increase the efficiency of the solar panel.

Mainly the middle class family and the rural areas of our country. The Power is the essential commodity that is required for the routine life. The increased dependency on continuous power supply in various domains like industrial production, shopping malls, big hotels, showrooms, manufacturing centres, electronics and lastly routine life for mankind makes the present society’s scenario more vulnerable related to power supply interruptions. A blackout for few hours or several days or even for a month will have a negative impact on the routine life as well as the entire economy. Critical infrastructure like communication and transport would be hampered, the heating of water for bathing and water supply for domestic and irrigation purposes would be stopped and the industrial sector including production processes and trading would cease. Hospitals would only work as long as the emergency power supply is supplied with fuel. Emergency services like fire, police and ambulance could not be called due to the breakdown of the telecommunication systems. Financial trading, cash machines, business sectors and supermarkets would also be shutdown, leading to a catastrophic scenario .


To increase the efficiency of solar panel we thought of making the arrangement in which panel will track the Sun just like Sunflower and also to save the solar panel from hailstorm or heavy rains we added the feature of flipping the panel using rain sensor and servo motor.

To increase the efficiency of solar panel we only thought of one solution that is to make Solar tracker.

Step 3DO

At first students designed the prototype of dual axis solar tracker, then decided the components required for making solar tracker like Arduino UNO, servo motors, Light dependent resistor, jumper cables etc. After 3-D printing the parts required for the project students assembled it and started programming the microcontroller. Once the prototype was ready students went to share it with Engineers of the same field, faculty members of Maharaja Sayajirao University and solar panel manufacturers and suppliers. They also showcased their idea and prototype with other school teachers and students.

Since this project is an innovative one, so sharing of the idea/prototype with the people of same field itself is the beginning of the desired change that we want in the society. The Engineers, faculty members and the solar panel manufacturers appreciated the innovative idea and the efforts put in by the students.


The Engineers, faculty members and the solar panel manufacturers appreciated the innovative idea and the efforts put in by the students. One comment from Dean of Faculty of Technology, Maharaja Sayajirao Gaekwad University Prof.Arun Pratap- " Very Innovative Idea and it is a good initiative by school students to make these projects that can change the future of renewable energy in India" Another comment from Akshay Gandhi, solar panel manufacturer and supplier in Vadodara ( Lobel solar power system) - " We generally install rigid solar panel at homes or at industrial level but the concept of solar tracker is really very fascinating. As it is more efficient than rigid one so we will now try to implement this idea for commercial purpose also."

We faced quite a few challenges: 1. At the designing phase , students were struggling with proper measurement of the parts required for 3-D designing in Blender. Due to power cut-off continuity of 3-D printing keeps on breaking. So it took lot of time to 3-D print the parts. 2. Programming of Arduino UNO and working with Light dependent resistor was also one of the challenges. We followed these steps to overcome the challenges: 1. To overcome the problem of discontinuity of 3-D printing due to power cut-off we connected 3-D printer with UPS/power back-up.

15-30 Days

Affordable and Clean energy

Our story is aligned with promoting the use of renewable energy (Solar Energy) and also to maximize the output from solar panel. Solar Trackers are devices that come in conjunction with the mounting structures and help direct the panels in the direction the sun moves. But as it stands today, trackers are gaining ground in India. Developers are becoming increasingly aware of the enhanced CUFs that tracker implementation could bring about. Basically, there are 2 types of trackers: Single-axis and dual-axis trackers As the name suggests, single-axis trackers rotate on one-axis, moving east to west, traversing the daily movement of the sun. On the other hand, dual-axis trackers perform both the daily as well as seasonal rotation of panels. Single-axis trackers can bring about a CUF of 21%. In comparison with solar plants without trackers, this means an increase in performance of around 20-25%.

Step 4 SHARE

Engineers of Electronics and communication technology, electrical and mechanical field, Faculty members of Maharaja Sayajirao University, Solar panel manufacturers and suppliers. We have also shared our idea/prototype on social media like Facebook and YouTube . The response was overwhelming. Everyone appreciated the idea/prototype and the hard work and efforts put in by the students.

More than 100

We will visit more solar manufacturer and suppliers, we will try to modify our project so that commercialization of our prototype will be easy.
