，”巴赫曼說。我們認(rèn)為：目前，只有第一個太陽能可以聲稱這些成就。巴赫曼的成本計算，當(dāng)然，在受到很多不同因素的情況下可能會得到不同的結(jié)論。部分的計算依賴于其他人在實現(xiàn)發(fā)電在不同地方所使用不同類型的面板。盡管如此，它突出的進(jìn)展，對整個行業(yè)來說是個重要的里程碑。并且太陽能發(fā)電并不是沒有限制因素。昨天，賽普拉斯半導(dǎo)體公司首席執(zhí)行官T.J.羅杰斯告訴一群記者說：“從晶體硅太陽能電池板得到的電力價格將低于煤電價格到2012年時當(dāng)傳輸線以及高效率官僚機構(gòu)和其他因素加進(jìn)來的時候。在起點是相同的”羅杰斯說。“我們將和PG&E（太平洋天然氣和電力）互相合作直至2012年。在未來兩三年內(nèi)，太陽能發(fā)電的電力價格將是相當(dāng)便宜。”羅杰斯的投資公司SunPower在2000年已經(jīng)有時40名員工。他把股份轉(zhuǎn)讓給賽普拉斯以后。SunPower公司現(xiàn)在能在一年出售價值數(shù)十億美元的面板。首個太陽能設(shè)備總部設(shè)在美國TEMPE，使用以鎘碲制造的薄膜太陽能電池板是將陽光轉(zhuǎn)化為電能關(guān)鍵。在大多數(shù)的使用單晶硅太陽能電池板今天，它能更多轉(zhuǎn)化陽光比那些制造商制造的薄膜。下一年，將有少數(shù)有能力的制造商將開始生產(chǎn)銅銦鎵硒（CIGS）太陽能電池。這個坐落在森普拉價值4000萬美元系統(tǒng)有168，300個電池板，其中第一個太陽能發(fā)電系統(tǒng)安裝費用為3.17美元每瓦，克巴赫曼寫道。（安裝的成本較高，因為它包括框架和安裝，而不僅僅是太陽能電池組件。）然后，他使用SunPower公司的電池組件安裝了一個14.2兆瓦的太陽能系統(tǒng)在內(nèi)利斯空軍基地，在與內(nèi)華達(dá)州的系統(tǒng)進(jìn)行比較。巴赫曼說，SunPower公司的晶體硅板成本為七點零四美元每瓦。在搞清楚多少電力系統(tǒng)發(fā)電，巴赫曼確定它的費用0.164美元每千瓦小時他的
