Di-it-yourself PV kits: Complete photovoltaic systems are not only available from specialized retailers or installers of solar systems. It is precisely the do-it-yourself enthusiasts who also rely on other sources, such as the German chain stores Obi, Toom, Globus, Tchibo, and even eBay. Nevertheless, the installers of solar power systems don’t have to start worrying about their volume of orders just yet.

Over the years, scientists of the US National Renewable Energy Laboratory (NREL) have made many important breakthroughs in their solar PV laboratories. However, making those breakthroughs commercial projects has often proven to be painfully slow. They are hoping their newest facility will help close that gap by integrating the best scientific precision measuring devices into a simulated industrial production line.

Triple Green, part 5: Mass production of CIS modules is largely possible without heavy metals and metallurgy. Theoretically, they as such have the best chance of becoming truly “triple green” (green energy, green recycling, green manufacturing). Nevertheless, there is still some need for development before these modules can be produced in a manner both environmentally and economically sustainable.

Anti-reflective solar glass: Solar glass is meant to protect modules from wind and weather. But it always reflects a small amount of sunlight, especially if the light hits the glass at a low angle. Anti-reflective coatings and structures can help, and increase module output, yet there remains no ideal solution for every application.

Solar panel orientation: Roofs that face towards south present ideal surfaces for photovoltaic installations. Yet with the decline in the prices for solar systems, more and more plants are being built on roofs that face towards east and west.

Management: Most people would be scared off by a constant pressure to perform, new situations and uncertain future prospects. Bona fide interim managers, however, thrive in such situations. They think of it as a challenge, as independence, and an opportunity to make a difference. Their creed? Roll up your sleeves and get to it. More and more solar energy companies are using these modern nomads to meet the quickly changing demands of the market.

Solar glass: A new float glass factory of F-Glass, a joint venture between Scheuten and Interpane, now makes very clear glass with low iron content. As a result, more sunlight is passed on to the solar cells and module efficiency increased. And as the glass is also coated directly in the production plant, production is also cheaper.

Ardour solar index: Positive data on end market demand is not enough to boost stocks, while feed-in tariff risk in Spain makes headlines.
