The lower the uncertainty in solar resource data, the lower the investment costs. IEA PVPS Task 16 has organized and published two benchmarks to make uncertainty of models and data comparable – a first important step. The benchmarks included modeled solar resource data and methods to fill gaps in measurements.

In its latestt monthly column for pv magazine, the International Renewable Energy Agency explains that, in order to realize Africa’s vast potential, we must ensure there is adequate investment and infrastructure development to support renewable energy. In the coming years, this means urgently overcoming the structural barriers across three priorities: infrastructure, policy, and institutional capabilities.

Indian scientists have produced high-purity polysilicon ingots from recycled solar cells using “spark plasma sintering” (SPS), and claim they may achieve a purity level comparable to commercially available products.

As the 40th edition of the European Photovoltaic Solar Energy Conference and Exhibition (EUPVSEC) gets underway in Lisbon today, it’s clear that European PV manufacturing faces some difficult challenges in the current climate of low prices and strong competition on all sides. Nonetheless, the show is already revealing plenty of optimism among the continent’s PV manufacturing players.

A Brazilian consortium is testing a new floating PV system design on a lake in the state of Sao Paulo. The facility is setting standards for future development of floating arrays in Brazil.

New research shows high potential for solar-powered vehicles across the world, providing between 11 km/day/kWp to 29 km/day/kWp of extended range in open areas, enabling significant levels of self-sufficiency.

The University of Cyprus and energy developer Ecotricity Holdings have jointly installed a nanogrid system for a single building in Cyprus. The aim is to minimize the site’s energy consumption costs and eliminate the power system’s carbon footprint.

Despite soiling and mechanical stress, PV deployed between or close to rail tracks is not just a crazy idea, states a Bangladeshi-Australian research group. The scientists conducted a techno-economic analysis on a 128 kW demonstrator and found it may achieve a levelized cost of energy of only $0.052/kWh.

Multiple factors affect the lifespan of residential battery energy storage systems. We look at the lifespans of batteries in the third part of this series.

Octopus Energy has developed new residential heat pumps, with plans to initially market a 6 kW version, followed by larger models in the near future. The UK-based company makes the heat pumps at its facility in Craigavon, Northern Ireland.
