The long read: Model progress

While it has often been referred to as “the future of PV” in recent years, discussions surrounding bifacial technology are now very much in the present. Modules are beginning to roll off production lines in significant numbers, and industry players are boasting of gigawatts of bifacial projects that are already installed or in the late stages of development. But it’s still early days for the technology, and there are questions to answer for it to achieve its full potential. pv magazine investigates the modeling and optimization of bifacial PV’s performance.

Net metering policy change could mean end of rooftop solar in Maharashtra

The recently proposed guidelines allow electricity cost reduction of only Rs 3.64/unit for commercial and industrial consumers, which is not even sufficient to recover the capital costs of setting up the solar infrastructure.

Tamil Nadu: Solar developers get relief as APTEL quashes power regulator’s unviable tariff order

The Appellate Tribunal for Electricity (APTEL) observed that Tamil Nadu Electricity Regulatory Commission (TNERC), in its Solar Tariff Order dated March 28, 2016, determined the tariff/capital cost without cogent or adequate reasoning while also being divergent from its own regulations.

Andhra Pradesh proposal casts doubt on India’s renewable sector: Rystad Energy

India may fall around 7 GW short of its ‘60 GW by 2022’ utility-scale solar target if the power purchase agreement revision proposal by the state government is implemented.

New metallization tech to reduce microcracks in solar cells

A U.S. research group has developed a metal-carbon-nanotube composite – MetZilla – which can be embedded in commercial, screen-printable silver pastes and is said to reduce the formation of hotspots in solar modules and to prolong panel lifespan. The composite metal contacts are also ‘self-healing’ as they are able to regain electrical continuity after cycles of complete electrical failure caused by extreme strain.
