Solar opportunities

Arizona, USA: Arizona is one of five U.S. states that added 50 megawatts of PV capacity in 2010. Governor Jan Brewer sought support for an even greater expansion of photovoltaics in Arizona at a Solar Opportunities luncheon in Shanghai.

Spot market for PV panels: Slipping prices

Module prices: Prices for PV modules will continue to decline until the end of the year.

“Good for the environment”

Indian solar market update: Mercom Capital Group provides an overview of the Indian solar market, including the funding status of current PV projects, accumulated capacity, and the country’s proposed pipeline.

Stable texturization process by carbohydrates

Stable texturization: Photovoltaic industries widely use the standard texturization method with NaOH/KOH and IPA (Isopropyl alcohol) to reduce reflectivity of monocrystalline silicon (<100> crystal orientation) wafers. IPA promotes the formation of uniform pyramidal structure but leads to unstable process. In this work, Microsol International’s Md. Al-Amin, A.K.M. Rahmatul Alam, Kiran Turlapati and Barath Baskaranathan have investigated carbohydrates as an additive in the etchant solution. It has no evaporation loss and thus leads to a stable process.

Achieving economies of scale

India: India has clearly caught the attention of the global PV industry, not only as an emerging market that promises to be at the vanguard for the next ten years in terms of growth, but also as an emerging manufacturing hub for the PV industry. India’s National Solar Mission (NSM) aims to install 20 gigawatts (GW) by 2022 in the country, although skeptics inside and outside the country are of the opinion that this target is a little too ambitious.

Technology switch

Concentrated solar power: The recent switch in Solar Millennium’s technology strategy to use PV technology rather than concentrated solar power in its 1,000-megawatt Blythe solar plant subsequently calls into question the economic viability and bankability of other CSP projects in the United States.

Bad and good news

Dear readers, Is mass extinction about to begin? A number of news items over the past few days and weeks are unsettling. Schott Solar has discontinued wafer production in Jena, Germany, and has shortened the work week for 350 staff members up to December. Phoenix Solar has seen its revenue and earnings outlook for this […]

The advent of grid parity

Spain: With the decline of module prices, solar energy in sunny regions such as Spain is taking big strides toward becoming competitive with conventional energy. This is even more important because Spanish solar energy technologies can no longer really depend on any future subventions, even though a new government will likely take over after the parliamentary elections in November.

Collapsing

Ardour Solar Index: Oversupply drives down pricing, and Solyndra questions continue to muddy the waters.

The power of software

Software: Implementing modern industrial application software can present a challenging and sometimes daunting mix of requirements. For example, it is well understood that a typical control system must interface with signals from simple sensors and actuators, yet for many modern applications this is merely the starting point.
