    A report presented at the Green Buildings Workshop
[SI indicated that building integrated PV (BIPV) could
provide positive economic value for a green buildings
strategy in China's leading cities. Besides rural
electrification, PV for high-density cities in China is also a
promising application area. If the BIPV market were to
grow, this would have benefits from rural users in the form
of lower product prices and improved technical
performance. Thus, an integrated approach to urban and
rural development of PV markets should be considered.


CONCLUSION

     PV in China has played a significant role in improving
people's living conditions, especially through rural
electrification. But to a large degree, this market is driven
mainly by policy and regulations. Grants have proved
essential to stimulating PV markets. But eventually, the PV
industry and users will have to be the principal responsible
parties if a sustainable future for PV is to be realized.
