Sharp Corporation has developed a polycrystalline photovoltaic module (peaked-roof/ flat-roof model: ND-191AV) that the company says achieves the industry's No. 1 module conversion efficiency of 14.4%. This module also features an installation capacity that is an average of 1.5 times greater than previous modules due to the strengthening of wind pressure resistance.
A total of five new fiscal 2008 residential models for Japan will be released. They are 191 watts (1,000 produced per month), 160 watt (10,000 units per month), 114 watts (4,000 units), and two 60.5 watts (each 1,000 units per month) variants
The five new models will incorporate a newly developed highly efficient cell that reduces the loss in power collection by increasing the number of main electrodes from two to three, and increases the light receiving area by making the electrodes thinner. As a result of these improvements, module conversion efficiency has been increased.
In addition, the strengthened wind pressure resistance of racking systems and modules allows them to be installed nearly all the way out to roof edges, expanding installation capacity considerably.
This conversion efficiency increase and expansion of installation capacity are possible due to the reliability and technological expertise Sharp has accumulated over the years. As an environmentally advanced company, Sharp will use this new line-up to help reduce residential CO2 emissions.
