According to a new study conducted by the Lawrence Berkeley National Laboratory, The average installed costs for photovoltaic cells (in real 2007 dollars) went down from $10.50-per-watt in 1998, to $7.60-per-watt in 2007.

What’s most amazing about this report is that it appears to validate a whole slew of state and local solar initiatives. The researchers found that—despite the many, many reported advances to solar cell efficiency—most of the savings during this nine year period came from reductions to installation and external hardware costs.

Sun Well Solar—a subsidiary of the notoriously poor CD and DVD manufacturer, CMC Magnetics—has announced today that it is one month ahead of schedule in the ramp-up of its new photovoltaic production line.

A US-based company has successfully tested a revolutionary solar panel that is expected to cut the costs of photovoltaic solar power generation by more than 50 per cent, and herald a new era of improved efficiency and lower production costs of solar energy globally.

The panel, known as the Alubond Solar Collector Panel (SCP), was created by American Building Technologies, a subsidiary of the UAE-based multinational group Mulk Holdings. Commenting on the breakthrough, a spokesman for Mulk said, “We hope the success of this project will lead to an upsurge in the development of more solar energy plants, which will not only lessen the strain on existing energy resources, but also severely reduce the pollution levels that are currently witnessed in power generation.”

One of the major barriers for anyone looking into a residential solar system is the hefty price tag, but a start-up called Solar Red claims it can halve the cost of residential systems. The company’s major product is a solar panel mounting system that uses brackets to weave in with roof shingles. These can be installed during construction or retrofitted. After the brackets are installed, the solar panels quickly snap into place.

Today is World AIDS Day. A day that is commemorated every December 1 to remind the citizens of the world that while great progress has been made in this epidemic, there is still a long way to go.

Art and craft has played a big role in both bringing awareness about the disease and how to cope. One of the most prominent displays of craft is the AIDS quilt.

Made up of individual “squares” that memorialize those who have been lost to the disease, the AIDS quilt is the largest on going community arts project in the world. It holds more than 44,000 individual panels made by friends, family and loved ones. And the 91,000 plus names displayed on the quilt, represent only 17.5 % of U.S. AIDS deaths.

Swiss company BKW has revealed that it plans to launch a 20-30 meter long solar-powered submarine. The vessel, to be used as a tourist attraction, will feature a huge ‘living-room’ style passenger area, as well as 60-70cm viewing portholes.

Under the plan, called Project Goldfish, a team of engineers will build a submarine, capable of carrying 20-30 passengers and two crew, at a depth of up to 300 meters across Lake Thun. Since it operates underwater, the team has figured that it’s pointless to attach solar panels on the sub itself. Instead, the vessel will fully recharge at a floating solar platform on the surface of the lake, decked out with 300m2 of solar collectors capable of supplying up to 30kW of renewable energy.

Solar PV manufacturer Oerlikon Solar has pioneered a new thin film solar technology process, which it claims has made its solar cells 7 per cent efficient - a 16 per cent energy improvement over its previous technology. The advance has led to a 50 per cent increase in the capacity of its thin film solar fabrication plant.

So, why is this important? Well, thin film cells are typically a lot cheaper to produce than more common silicon solar cells, but often suffer from significantly lower conversion efficiencies. Oerlikon’s breakthrough moves us a lot closer to the day when thin film becomes more cost-effective than silicon-based panels - which could mean a dramatic rise in the adoption of solar power in homes and businesses.
