Nippon Oil Corp,also know as Eneos and Sanyo Electric Co Ltd have a joint venture – 50:50 to produce amorphous Si thin-film solar cells and marketing power generation systems. Panasonic, which recently bought Sanyo has not put up any money yet.

Sanyo will develop manufacturing technologies for thin-film solar cells as well as the production of cells and modules. Eneos will make large-scale power generation systems using the modules. Eneos is also responsible for distribution and sale as well as provide material technologies for gases (eg, hydrogen gas) required in the cell production.

“The establishment of the new company is part of our efforts to become a comprehensive energy provider based on solar cells, fuel cells and rechargeable batteries, which are like the ‘three musketeers of batteries,’” Eneos President Shinji Nishio said.

Sanyo Eneos Solar have a target of 80MW per year sales with an energy conversion efficiency of 10% by 2010. Full-scale mass-production and an annual production of 1GW with conversion efficiency of 12% or higher by 2015. 2GW/year production by 2020.

The power generation systems are expected to be installed mainly in the Middle East.

Sanyo says it can make up for the slow start through superior technology and reliability.

“The solar cell business is a long-term project with its focus on 2020 or even 2050,” he said. “We are not at all concerned about a short-term depression. For manufacturers that have the lead in the thin-film solar cell production (by purchasing the production equipment in whole), the conversion efficiency will probably peak at about 7%.”

“In contrast, we will promote the research and development concurrently with the production and will constantly improve our technologies to achieve an efficiency of 10%, 12% and higher,” he said.

Business is good in the solar energy industry and will be so for a long time to come. Wonder if those report

Panasonic is planning to spend Y100 billion ($1billion+ depending on the yen rate) to develop eco-friendly energy technologies like rechargeable batteries and solar cells.

This plan is in align with the company’s desire to acquire Sanyo Electric for a sum close to $9 billion.

Sanyo’s strength is in rechargeable batteries (leader in Li-ion batteries) and solar cells (ranks 7th), which Panasonic considers as strategic areas.

“We needed to take drastic measures to secure growth amid a global economic downturn and structural changes in the electronics industry,” said Panasonic’s President, Fumio Ohtsubo.

When the two are combined it will create a giant manufacturer more competitive to ride out a worsening global downturn, with consolidated sales of more than 10 trillion yen, equal to Japan’s No 1 electronics and electrical machinery maker – Hitachi Ltd.

The Panasonic/Sanyo duo will also make for a powerful force in developing eco-friendly technologies, too.

Sanyo Electric will release an electric hybrid bicycle that has a Lithium ion secondary battery and a twofold assist force, early next February 2009 in Japan.

Dubbed the “eneloop bike (product No: CY-SPA226)” it’s an industry’s first product that reflects revisions in the Road Traffic Law Enforcement Regulations that came into effect on Dec 1, 2008. The maximum drive assist ratio (motor drive force to human power) is 1:2 in Japan. The 26-inch bicycle will cost ¥136,290 (approx US$1,463, including tax).

The motor that drives the front wheel is brushless motor and has a rated output of 250W. The rated voltage and capacity of the Lithium-ion secondary battery increased 1.5 times to 25.9V and 6.0Ah, respectively. The charging time increased from two to 3.5 hours.

The eneloop bike uses the assist motor as a generator during braking and downhill riding for recharging and can run in:

1. Auto mode switches between assist and power generation automatically.
2. Power Up mode provides a continuous assist force = double human power.
3. Standard mode provides an assist equivalent to human power and recharges the battery when braking.

The cruising distance of the bike is 57km (33mi) without regenerative charging and it is 75km (60mi) in the Standard mode where regenerative charging occurs during braking. In the Auto mode, the travel distance reaches 100km.

Sanyo also released a model with a Ni-hydrogen secondary battery. But the cruising distance of this model in the Auto mode is only 53km.

The electric hybrid bicycle market sold 283,000 units in 2007. Sanyo hopes for 300,000 units in 2008.

Ah, this is something Japan knows how to do, and do well. Research.

Sharp Corp. Sanyo Electric Co. and 15 other companies has joined forces with Gifu University to conduct research on nanocrystalline silicon, a promising material for highly energy-efficient thin-film solar cells.

The consortium will

1. explore the nanocrystalline silicon as the next-generation photovoltaic material = solar cell. Japan is a leader in solar cells and wants to pull far ahead.
2. analyze the properties of nanocrystalline silicon
3. collect the kinds of basic data needed to develop solar cell materials
4. use a scanning probe microscopes to observe electron movements in the silicon when the material is exposed to light
5. study unknown phenomena taking place on the surface of the silicon thin film
6. create a device to use for quick, objective evaluations during the product development process.

In the end, cheaper and more efficiently made and higher quality products, if Japan does what Japan does best.

Sanyo Electric is, no doubt, a leader in the solar cell industry. The company just opened a new production base in Shiga, Japan. Annual capacity is expected to reach 40MW by March of 2009. Adding in its Tokyo plant, Nishikinohama plant, Hungary plant and Mexico plant, total production will reach 340MW.

It’s not enough. Sanyo wants production to reach 600MW by March 2011 (Japan’s fiscal year ends in March). By 2020, Sanyo wants to roll out 4GW per year.  Japan’s Shiga plant is a module plant, meaning it can grow as demand grows…and we do hope that there is a demand for more solar power in the future, don’t we?

And, if you don’t want to pay out the gazoo for Japan’s expertise, efficiency and quality, there are always Beer Bottles to use fo Solar Water Heating.
