NIT Rourkela secure Patent in New Solar Technology

by

National Institute of Technology (NIT) Rourkela has secured a low-cost technology patent which is designed to optimize the energy output from solar panels. This groundbreaking technology is a revolution in the field of solar power generation by improving efficiency, reducing the effective costs, and increasing the overall viability of solar energy as a sustainable power source. The patented technology has the potential to accelerating the global transition to clean energy and contribute significantly to India’s renewable energy goals.


According to one of the researchers, Mr. Susovon Samanta, Associate Professor in Electrical Engineering at NIT Rourkela, solar panels generate electricity by converting sunlight into power, but their output fluctuates throughout the day due to changes in temperature and sunlight intensity. The technology developed is called Maximum Power Point Tracking (MPPT), which ensure the panels consistently generate maximum energy. According to this technology, the system is designed in such a manner that it will adjusts the voltage and current based on sunlight and temperature.

First Solar sues JinkoSolar over Infringement of New Patent Technology

by
First Solar an US solar panel manufacturer, has initiated legal action against JinkoSolar (Chinese solar panel manufacturer), alleging infringement of its U.S. Patent No. 9,130,074, which pertains to tunnel oxide passivated contact (TOPCon) solar technology. This patent was obtained by First Solar in 2013 through its aquiring of TetraSun, Inc.

The lawsuit was filed in the U.S. District Court for the District of Delaware. First Solar claims that JinkoSolar’s use of TOPCon technology infringes upon its patent rights. In defense, a JinkoSolar spokesperson stated that the company is having proof that the claims lack merit and intends to vigorously defend itself against what it considers baseless allegations by First solar.

Currently, the legal action is part of a broader trend in the solar industry, where several major manufacturers are engaged in patent disputes over TOPCon technology. In October 2024, First Solar notified several large competitors, including JinkoSolar, of alleged infringements on its TOPCon patents.

The outcome of this lawsuit could have significant implications for the solar industry market and manufacturers , particularly concerning the development and commercialization of advanced solar technologies like TOPCon worldwide.

Longi sues JinkoSolar for infringement of new patent technology

by
Longi, has filed lawsuits against JinkoSolar for their patent infringement, both the companies are leading players in the solar industry. The legal actions have been initiated in both countries China and the United States.
In China, Longi has filed the lawsuit at the Jinan Intermediate People’s Court in Shandong and requested an immediate halt to the manufacturing, sales, and offers to sell the allegedly infringing products and other related activities to it. The Court has accepted the case, with an expected trial date of March 20.

In the United States, the lawsuit was filed at the U.S. District Court for the Eastern District of Texas, alleging patent infringement of Jinko Solar’s TOPCon and multiple other unspecified photovoltaic module products.

Longi claims that JinkoSolar has infringed upon its intellectual property (IP) related to solar technology, specifically patents concerning the production and design of solar cells and panels. This dispute comes out as both companies are at the forefront of solar technology innovation. The patents plays a critical role in protecting advancements in the highly competitive solar energy sector.

The lawsuits highlight the ongoing tensions in the renewable energy industry, where patent disputes are becoming increasingly common as companies rush to secure a competitive edge in the rapidly growing market for solar energy products. In these types of cases, the outcome can impact product sales, partnerships, and overall market positioning for the companies involved.

It remains to be seen how these lawsuits will unfold, but they signal the importance of intellectual property rights in the clean energy sector.

New Solar Technology Patent from Gujrat called Dual-Axis live Tracking

by

Deeptanshu A Gadhavi, a student from the Parul Institute of Hotel Management and Catering Technology, has created a dual-axis solar tracking device, which is designed to improve the efficiency of solar panels. Though he is studying hotel management, his passion and talent for innovation have led him to develop a groundbreaking invention in the field of solar energy technology.

Typically, the solar panels remain stationary through out the day, meaning they only capture sunlight that directly hits them during certain times of the day. This device allows solar panels to track the movement of the sun throughout the day and enables solar panels to move along two axes, mimicking the movement of the sun. This results that the panels can capture sunlight more effectively, no matter about the position of the sun in the sky.

Key Features of the Invention:


Dual-Axis Tracking:
The system can rotate 360 degrees, which is different from the conventional single-axis tracking used in many existing solar system. This allows the solar panels to capture sunlight from all angles, which maximizing energy absorption.


Automatic Weather Protection:
The invention also includes a weather protection system that automatically adjusts the panels when bad weather is detected, such as heavy winds or storms. The device will protect the panels from potential damage during extreme weather conditions, which is a common problem in existing solar panel setups.


Efficiency Boost:
This solar tracking device has the potential to increase the energy output of solar panels by 20% to 30% compared to conventional fixed-panel solar systems. This efficiency gain would significantly improve solar energy production and its practicality for large-scale use.
This invention has successfully secured a patent in India and has also received a design certificate(6225872) from the UK Intellectual Property Office.


This innovation is a great step forward in field of renewable energy technology, contributing to sustainable solutions for green energy and solar power production system.
