你住几年卖房子，没付完，连房子都卖不掉吧，而且SOLAR系统的效率
每年递减的,20年之后估计就发不出电了，现在的电费没有200刀一个月
都不值得做。什么环保啊，不生孩子不消费最环保，经济上不划算

. It has some not so obvious reasons. Yes, longs see that the US tax break
bill is passed and tax benefit for solar is lifted. That is a fundamental
good news. But it is only an extension. That is, in 2007 and 2008, the same
policy is there. Nothing more, nothing less.
That is the bright side. On the other hand, one should know that US solar

发帖数: 812 | 16 solar is a long term play -- while people invest only look at near term
performance.
cheaper crude oil discourages people to use solar -- which, at least , is
the market perception.
so what brings up today's market, presses solar sector down. |

SAN FRANCISCO (MarketWatch) — Energy stocks led a Tuesday decline in U.S.
stocks, dragged down by multiyear lows in oil futures prices precipitated by
news that Saudi Arabia, the world’s No. 1 oil exporter, had cut the price
of oil sold to the U.S.
That added pressure on smaller U.S. producers as it calls into question
those producers’ ability to withstand a long slump in prices and a direct

of known inner Solar System objects on 2002 July 20. The light blue lines indicate the orbits of

Explanation: Only in the fleeting darkness of a total solar eclipse is the
light of the solar corona easily visible. Normally overwhelmed by the bright
solar disk, the expansive corona, the sun's outer atmosphere, is an
alluring sight. But the subtle details and extreme ranges in the corona's
brightness, although discernible to the eye, are notoriously difficult to
photograph. Pic |

This built-in voltage, I don't know exact meaning, is caused by contact.
Chooce different metal contact will change efficiency of it.
If you want to apply your field in solar cell, that is the field you may look
at.
For charge separate part, it is nothing involved with metal.
