Solar- the key to net zero for India
All you need to know about business model of solar power generation
By Ajay Singh Rathore • Sun Mar 08 2026
In Nov 2021, during COP26 climate conference, Government of India announced the target of achieving net zero carbon emission by 2070. In line with that, GOI has set target of installed renewable capacity of 500 GW by 2030.
As on 31st March 2024, India has approximately ~434 GW installed power generation capacity, out of which installed renewable energy capacity is ~183 GW. Because of geographical location and advancement in technology, the most important source of renewable energy is solar energy which stands at ~75 GW as on 31st March 2024 as depicted in the below pie chart.
From Crisis to Stability: The Role of Late Payment Surcharge (LPS) in India’s Power Sector
By Anju Shekhawat • Sun Mar 08 2026
For years, India’s power sector particularly the distribution segment has grappled with chronic payment delays. State-run electricity distribution companies (DISCOMs), particularly in states such as Andhra Pradesh, Telangana, and Tamil Nadu, have long struggled with financial distress. By mid-2022, these systemic weaknesses had escalated into a liquidity crisis. Power generators (GENCOs) and transmission licensees (TRANSCOs) were left waiting for months to receive payments. At its peak in June 2022, the total overdue amount owed by DISCOMs had surged to ₹1.3 trillion.
Sand to Solar Panel: The Process of Solar Panel Manufacturing and Transmission
By Ajay Singh Rathore • Sun Mar 08 2026
In our previous article, we explored the business model of solar power generation. With India’s ambitious target of achieving 500 GW of installed renewable power, numerous companies are establishing solar cell or module manufacturing facilities across the country. This makes it crucial to understand both the manufacturing process of solar modules and the process of transmission of energy to consumers using transmission lines, substations and transformers.
How P-N junction of a Solar Cell Works
By Ajay Singh Rathore • Tue Feb 10 2026
In the previous article, we discussed that boron and phosphorous were added to silicon to make P-N junction. This article is relevant only for those people who want to understand P-N junction in detail. To recap, electrons are negatively charged so the side with higher concentration of electrons is called as negatively charged region (N side), while the other side has lesser electrons, hence known as positively charged region (P side). This allows electrons to flow from the negatively charged region to the positively charged region. To understand in detail, why they were added to the silicon, we need understand basics of an atom as every metal in the world is made of atoms including silicon, boron and phosphorous.
SECI's Crucial Role: Ensuring Payment Security and Facilitating Green Energy Transition
By Ajay Singh Rathore • Mon Dec 01 2025
India, as a signatory to the Paris Agreement in 2015, has committed to achieving net zero carbon emissions by 2070. Three key pillars of the Government of India's strategy to achieve this target are Solar Energy Corporation of India (SECI), National Thermal Power Corporation (NTPC), and Satluj Jal Vidyut Nigam (SJVN). These entities are Central Public Sector Undertakings, each playing a crucial yet distinct role in promoting renewable energy. Today, we will discuss about how SECI is helping build a positive atmosphere for the development of renewable energy.
