Exciting developments are occurring in solar PV (photovoltaic) power generation. New technologies are improving manufacturing processes. Thin-film and organic (plastic) films promise to reduce PV power cost. Solar “grid parity,” the time when solar power will cost the same as fossil fuel power, is coming soon.
An Italian company has announced plans to install the world’s largest rooftop solar photovoltaic plant, with an energy capacity equivalent to the power needs of 5,000 households.
Solon SE will establish the facility at its Padua warehouse and truck-loading complex, generating an output of up to 15 megawatts when the sun is at its brightest.
As I write this I am preparing to board a very long flight to China, where I’ll be talking to a few Chinese PV module manufacturers, as well as our existing inverter supplier, Motech, in Taiwan. This will be a chance to meet and greet potential future suppliers on their own ground, and review factories as we consider sourcing more materials from China, but there are many things I already know before embarking.
New York Times Columnist, Tom Friedman is right. China is investing heavily and preparing to leave the rest of the renewable energy world in the dust. In the past two weeks Suntech, currently the largest solar module manufacturer in the world, signed 2 GW (2000 MW) of projects in China. Those 2 GW represent merely the contracts of a single company. Last year – and likely this year – the total U.S. market is 350 MW (0.35 GW). Granted, not all the Chinese projects happen this year, but plans are on paper – there is a schedule.

Like a tide turning, there’s a big shift happening in the solar market that many people aren’t really seeing because they’re bobbing about on an ocean of opportunity. The implications are huge in terms of who will get capital and attention in the industry, and the trend should lift all boats and take this solution to climate change further than before.
PlanetSolar, when completed and covered with 1500 square feet of solar panels, will be the largest solar powered ship in the world. A ship with an audacious agenda: to be the first to circumnavigate the globe powered solely by solar energy.
“In 2010, the first round-the-world trip powered by solar energy will be realized, with stopovers, along the equator, where the maximum amount of sunlight is available. The over 40,000-km voyage will last 120 days, for an average speed of 10 knots. PlanetSolar’s two-man crew will cross the Atlantic Ocean, the Panama Canal, the Pacific Ocean, the Indian Ocean and finally the Suez Canal, to return to the Mediterranean.”
The eco-city, called Babcock Ranch, is a joint venture between a real estate developer, Kitson & Partners, and Florida Power & Light, and will be located near Fort Myers, Florida.
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.

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.
There is much useable roof space in our communities, and architects are looking beyond homes for solar installations. With an increase of plug-in hybrids and electric cars about to hit the market, solar carports make sense. Standard products, like this solar carport, cost less than custom PV projects.
