Inverters

Yotta Energy’s new micro-inverter is claimed to be an ideal solution for commercial rooftop PV systems linked to between 500 kWh and 1 MWh of storage. The device has a peak efficiency of 96.5% and a nominal maximum power point tracking (MPPT) efficiency of 99.5%.

Sunil Thamaran, India head for USA-headquartered Enphase Energy, explains why microinverters are a good investment for rooftop solar. He also talks about the trends in microinverter design and their company’s India plans.

The selected vendor shall also be responsible for installing and commissioning the power-conditioning units (central inverters) at the solar sites in Madhya Pradesh.

Researchers led by the Indian Institute of Technology Delhi have projected the waste expected from end-of-life solar panels and related components. They assumed 347.5 GW of total installed solar generation capacity would be reached this decade. The academics said the waste would include critical metals worth around $645 trillion, 70% of which could be recovered.

The sheer volume of new power lines which will be required to accommodate the rising tide of solar installations ensures copper has been included by the International Energy Agency on its list of minerals which must keep flowing if the energy transition is to stay on course. And it’s not production that’s the potential bottleneck.

Solar installer Jake Warner has received surprising feedback from his customers after he chose to transition his company, Penrith Solar, exclusively to microinverters two months ago. “What I found is actually the opposite to what I expected,” Warner told pv magazine Australia.

The Chinese manufacturer commanded a 17% share of the total 3268 MW of rooftop PV inverter shipments in India in the January-December 2020 period.

The device was developed by an international consortium through the EU-funded project Renewable penetration levered by Efficient Low Voltage Distribution grids (RESOLVD). The power electronic technology is claimed to be able to combine different storage technologies in a single electronic-based board interface.

Imported solar inverters and lanterns will get costlier, as the union budget for the next fiscal year has proposed customs duty increases from 5%, for both items, to 20% and 15%, respectively. The budget, which also incentivizes Indian manufacturing of solar project components whilst giving a helping hand to raw materials, makes no mention of solar cells or panels.

The EV manufacturer with big solar ambitions has finally leveraged its expertise in power electronics technology and launched a solar inverter.
