Technical Commentary: Bifacial Solar Module Performance

Bifacial solar photovoltaic modules convert solar radiation received on their front and back sides into electricity. Calculating the solar energy generated by solar radiation received by the back side is complicated by shadows, varied weather and dust conditions by day and season, back side equipment and reflections, and albedo.

Long term prospects for Renewables remain in-tact; Near term headwinds amid the COVID impact on discoms’ finances

The renewable energy-based capacity is estimated to reach to 120-125 GW by December-2022, with the solar capacity constituting 50% of the overall capacity followed by 38% from wind power segment and the balance 15% from other sources. While this is lower than the capacity target of 175 GW set by the Government of India, the incremental capacity addition is estimated to be healthy at 35-38 GW with investment outlay of more than Rs. 2 lakh crore over the next two and half years

Explore the Reasons Why Dry Type Transformers Are Now Being Preferred over Their Oil-type Counterparts

The chief purpose of a transformer in an electrical route is to shoot up or reduce voltages. Although one can find a plethora of different kinds of convertors available in the marketplace, but the dry type is highly commended to use, since they are cost-effective, more efficient, and come up with more safety features.

Technological Advancements in the Solar Sector in India: Evolution for the Past Decade

In 2010, the total installed solar capacity in the country was nearing 10 MW. Thereafter, practical use of solar power as a mainstream energy source showed phenomenal growth, reaching more than 37 GW installed capacity in 2020. The primary drive behind this growth was Government support with worldwide acceptability of solar creating an environment of continuous technological evolution.

How Inverter’s MPPT Structure Affects Power Generation

Different MPPT structure will affect the solar system production. From the perspective of solving the mismatch problem, one MPPT with fewer strings is better. However, in terms of stability and efficiency, the more strings for one MPPT, the better it is, because if with more MPPT, the higher the system cost, and the more the loss. In practical applications, it is necessary to combine the actual terrain to select the appropriate solution.

Energy Storage Systems and Smart Future Cities - An Indian Perspective

Today, 54% of people worldwide live-in cities and this is expected to reach 66% by 2050. Overall population growth and urbanization is expected to add another 2.5 billion people to cities over the next three decades. Energy storage has been identified as a key to climate change mitigation. Globally, only 3% of power capacity is being stored. To limit global warming to below 2°C, energy storage capacity needs to triple by 2050.

Global Experience of Retail Competition in Power Supply and Implications for India

If retail competition is introduced to the power distribution sector, and the ‘supply’ and ‘wires’ business separated, what are the implications for India? This article, explores the international experience of market-based reforms, and contextualize them to India’s own reform experience. Given the risk the disruption poses to the supply obligation for universal electricity access India’s aggressive renewables transition, the authors question the suitability of ‘retail competition’.
