Keeping PV components “green”

Sustainable PV: Just as module efficiency does not depend only on cell architecture developments, so too does sustainable solar come right down to the components. This is the case from solar glass through to backsheets. The use of fluoropolymers in backsheets supplied to the industry has some worried about toxicity issues when modules come to their end of life.

Merchant solar

New business models: As global solar markets mature and reach more and more locations around the globe, opportunities for new business models open up. Among the most interesting of these is merchant solar, where projects sell the electricity they generate on the spot market.

“It’s a one-two punch”

Clean energy revolution: Tony Seba is a lecturer in entrepreneurship, disruption and clean energy at Stanford University. He spoke to pv magazine about the themes in his new book, Clean Disruption, which looks at how solar, electric vehicles and other exponential technologies are leading to a clean, knowledge-based energy era.

New finance models primed for Southeast Asia

Southeast Asia: The southeastern region of Asia has an enviable solar resource and is home to some world-leading finance centers. The right combination of homegrown innovation and responding to global trends in finance will help to make the most of solar in the region. Ragna Schmidt-Haupt of DNV GL identifies several new global and local financing trends that could have a big impact in the region.

A model to replicate

Solar in the Gulf region: The Dubai Electricity and Water Authority procured the world’s cheapest solar energy ever in a call for tenders last November. Moritz Borgmann, Partner at Apricum, a Berlin-based advisory firm specialized in renewable energy technologies, analyzes the results of the 100 MW solar PV tender and gives his view on the wider implications for the region.

N-type mono is coming

Solar cells: N-type mono wafers are the foundation for the most successful high efficiency solar PV cell designs on the market. But will they replace p-type technology for monocrystalline silicon PV, and when?

A panel decision

Module-level disruption: Power electronics at the module level are a growing part of the energy management system, offering immense potential in data monitoring that can push LCOE into the hands of the consumer. pv magazine explores some of the technologies that are set to shake up the residential solar sector in the near future.

Off-grid power for small-scale enterprises

Ethiopia: Light, services, energy – PV can deliver tangible benefits to communities beyond electricity grids. It can also create new business opportunities in rural areas, as has been demonstrated in Ethiopia where businesses, a university and government are coming together to facilitate solar’s transformative growth. pv magazine spoke with Engidaw Abel Hailu, Manager at the Solar Competence Center (SCC) of Arba Minch University, Ethiopa.

Anti-reflective coating the new normal

ARC glass: Incremental improvement in materials can have a major impact on overall module efficiencies and therefore cost per watt. Anti-reflective coating certainly fits that description and is fast becoming ubiquitous in PV glass manufacturing. Technological variations exist in terms of ARC material and application and the key metric, it seems, to this particular ARC lever is proving durability in a range of conditions.

On the cusp

Off-grid PV: Of the 1.3 billion people without access to electricity, more than 80% live in rural areas far away from the existing power grids. Because of the problems to finance the up-front cost of a solar PV system with a battery, diesel gensets are still the preferred energy solution in many of these areas.
