Production Line for MH/Ni Power Battery Is Formally Begun Reconstruction


(Oct.31,2005)

¡°Tackling Key Technical Problem for MH/Ni Power Battery¡± has been started to run formally at present, which is the first international inviting public bidding project in Baotoua and is won the tender by Sanoh Industrial Co. Ltd. According to requirement of the first stage on bid document, three technical personnel from Sanoh reached Rare Earth Ovonic Co. Ltd on September 5 and began to evaluate the production line.
The inviting public bidding was supported greatly by Baogang Group Company, the board of directors of which held the meeting to listen to the report about production line for MH/Ni power battery and solved problem of capital shortage. In the mean time Rare Earth Ovonic Company negotiated actively with American Ovonic Company and successfully made Ovonic Company agree to use unpaid money of more than US$ one million for reconstruction of the production line, which laid a food foundation for the project.

According to requirement of bidding document, production capacity will be up to 7 million units with production value of RMB£¤210 million and battery capacity will be increased to 8.5¡À0.26Ah from 7¡À0.5Ah while qualified ratio of product will be improved from 50% to 88% after reconstruction.

I will post steps to get to site of this post. Can't paste. i think its because of translation of chinese.

For many years, amorphous silicon photovoltaic modules have had difficulties to establish themselves in the grid-connected PV-market. Causes for this lack of market acceptance of first generation amorphous silicon PV modules were their relatively low conversion efficiencies, unstable power and not well understood outdoor characteristics. Various manufacturers of amorphous silicon modules have resolved these initial problems by enhancing the efficiencies of their cells, while at the same time improving the long-term stability of the products. Still, the outdoor behaviour of amorphous silicon modules is not well understood by many users, even by insiders of the PV-community. Results of this study will show that new generation multi-junction amorphous silicon modules, and in particular UNI-SOLAR® modules based on the Triple Junction solar cells, perform excellent under western European climatic conditions, with yields and performance ratios significantly higher than all present crystalline silicon technologies. This effect is especially pronounced under low light conditions and under non-ideal orientations. The enhanced outdoor performance, up to 20 % higher on a yearly kWh/kWp base, can be attributed to the higher sensitivity for low light conditions and for diffuse light, better performance at high temperatures and improved shadow tolerance of UNI-SOLAR® modules.....

........CONCLUSIONS
The gathered data have shown that new generation multi-junction amorphous silicon solar modules, and in particular UNI-SOLARâ PV-products using Triple Junction solar cells, show good stability and excellent outdoor performance. These PV-modules actually perform better in real outdoor conditions than all competing c-Si and other thin film silicon products. The higher energy production of UNI-SOLARâ PV-products, up to 20% kWh per kWp purchased, can be understood by their excellent conversion efficiency at low light levels and their relatively insensitivity to ambient temperature.

I especially like this from the same document......

On a private house in a suburb of London (Richmond), a 1.632 kWp UNI-SOLARâ PV-shingle roof has been installed in March 1999. It is the first PV-installation in the UK to be completely made using electricity generating shingles. The PV-system consists of two separate parts: 64 SHR-17 PV-shingle units are installed on the southern face of the roof (total rated power 1.088 kWp), while 32 SHR-17 PV-shingle-units were placed for testing purposes on the northern slope (total rated power 0.544 kWp). The roof inclination is 40°. The PV-shingle units are connected in 6 series strings of 16 units, which are distributed over three SMA Sunnyboy SWR700 inverters. In the period March 1999 until March 2000, the southern slope system generated a total of 900 kWh, corresponding to a specific AC-yield of 827 kWh/kWp for the full year. This yield is very high for UK standards, especially if one considers the location of the installation: an urban environment close to a large airport (London-Heathrow) that causes serious air pollution. A typical c-Si PV-system under the same condition would generate in London no more than 700-720 kWh/kWp per year [5], some 15% less. It is interesting to note that the northern face installation also had a high yield: 528 kWh/kWp for the same period. This yield is still some 64% of the one of the southern face installation despite the fact that the insolation on that plane is more than 45% less than on the southern slope. This is a clear indication that UNI-SOLARâ PV-products perform well under non-ideal orientations.

How many crystalline systems can produce 64% of full sun exposure from the diffuse light of the rest of the sky? That's why we start producing from firstlight, while the others have to wait until the sun comes up to a higher angle.

Also note that over a years time the Unisolar panels, rated at 64 peak watts, produced 1341 kW hours, for the highest preformance ratio of 93%.

Here are some other popular brands, with their rated peak output, and their actual output for a year.
