Our Project

Dr Shyama Prasad Mukherjee Indoor Stadium is an indoor stadium located on the campus of Goa University at Taleigao, Goa, India. The stadium was constructed for the 2014 Lusophony Games for events of volleyball and basketball. The stadium is named after Dr Shyama Prasad Mukherjee former Indian politician and the founder of Bhartiya Jana Sangh. The stadium has a seating capacity of 4000 and was inaugurated by Governor of Goa Bharat Vir Wanchoo in 2014. It cost 82 crore and was built in 11 months which is a record for the construction of an indoor stadium of international standard. With a 131-metre sheet, the stadium is Asia's first stadium which has the longest single-sheet roof.

Location was strategically chosen to highlight India’s first-ever vertical solar installation featuring advanced 5th Generation Seclink Sedi modules during the G20 Summit in Goa.

The Challenges

There were many challenges to setup the solar modules as follows:

• Time for the installation : The decision to establish the PoC was made in June 2023; however, the final location was confirmed on July 11, 2023. With the installation scheduled to be showcased during the G20 Summit from July 19 to 21, 2023, we had only 8 days to complete the installation.


• Direction of the wall : The site survey was conducted on July 12 and 13, 2023, during which it was discovered that the façade faced southeast, leaning more towards the east, rather than south-facing. This orientation would not provide optimal sun exposure for the solar modules. Nevertheless, this was embraced as a challenge to demonstrate that Seclink Sedi modules could still generate substantial energy even in less-than-ideal conditions. Once the decision was made, the materials were transported from Mumbai to Goa on July 14, 2023.


• Weather Conditions : Unfortunately, the peak monsoon season in Goa brought heavy rainfall, posing another challenge for the installation. The weather prevented any attempts to install the modules, forcing us to wait for two days until the rain subsided. On July 17, 2023, the skies finally cleared, and the installation work began.


• Availability of cranes with long booms : The finalized wall for installation was approximately 17 meters high, requiring a crane of considerable size. The only available crane on-site belonged to the Fire Department, and an additional day was needed to complete the necessary formalities to secure its use. Work finally began on July 18, 2023. However, the crane broke down after installing about 15 panels, prompting a search for a replacement. This search caused a two-day delay, and installation resumed on July 20, 2023.

Project : POC test points

1. Seclink Sedi modules can be installed vertically without any particular angle - The test was successfully passed, as the panels were installed facing the southeast—far from an ideal orientation for solar installations by any standard.

2. How easy it is to install the Seclink Sedi modules - The installation was completed in just 15 hours by a team of only three technicians, demonstrating the ease of installing Seclink Sedi modules. This achievement was accomplished despite the rainy and highly adverse weather conditions.

3. Does it generate energy by installing the same in adverse conditions - July, being the peak of the monsoon season, presented highly unfavorable conditions for energy generation. However, the following graph illustrates that the Seclink Sedi modules successfully generated substantial energy over these nine days in July 2023.

4. Does it generate energy without a particular angle? - As noted earlier, the Seclink Sedi modules were installed vertically, deviating from the conventional installation method of a 18-degree tilt facing true south for maximum sunlight exposure. These modules received sunlight for only 4 hours daily, compared to the 8 hours they would have received if installed on a south-facing façade. Despite this limitation, they still generated sufficient energy. The real-time graph below illustrates the actual sun exposure, showing a peak lasting only three hours, from 9 a.m. to 12 p.m.

5. Maintenance aspect - Since the installation of the plant, there has been no need for any type of maintenance. The modules have not been cleaned or washed over the past 290 days, yet this has not impacted their efficiency or performance in any way.

6. Others - The efficiency of the panels has been recorded at approximately 16.23% under optimal weather conditions and around 9.62% during adverse weather. We are confident that Seclink Sedi panels will achieve their maximum capacity of 21.8% when installed in ideal conditions.

Project POC was 100% successful and has achieved all the goals set for it.
