太陽能的利用目前還不是很普及，利用太陽能發電還存在成本高、轉換效率低的問題，但是太陽能電池在為人造衛星提供能源方面得到了應用。人類依賴這些能量維持生存，其中包括所有其他形式的可再生能源(地熱能資源除外)，雖然太陽能資源總量相當于人類所利用的能源的一萬多倍，但太陽能的能量密度低，而且它因地而異，因時而變，這是開發利用太陽能面臨的主要問題。華揚太陽能的(de)(de)(de)這些特點(dian)會使(shi)它在整個(ge)綜合(he)能(neng)(neng)源體(ti)系中的(de)(de)(de)作用(yong)(yong)受到一定的(de)(de)(de)限制。太(tai)(tai)陽(yang)(yang)能(neng)(neng)熱(re)水(shui)(shui)(shui)(shui)器(qi)是(shi)將太(tai)(tai)陽(yang)(yang)光能(neng)(neng)轉(zhuan)化(hua)為(wei)熱(re)能(neng)(neng)的(de)(de)(de)裝置(zhi)，將水(shui)(shui)(shui)(shui)從低(di)溫加(jia)熱(re)到高溫，以滿足(zu)人們(men)在生(sheng)(sheng)活、生(sheng)(sheng)產中的(de)(de)(de)熱(re)水(shui)(shui)(shui)(shui)使(shi)用(yong)(yong)。太(tai)(tai)陽(yang)(yang)能(neng)(neng)熱(re)水(shui)(shui)(shui)(shui)器(qi)按結(jie)構形式分為(wei)真(zhen)空(kong)管(guan)式太(tai)(tai)陽(yang)(yang)能(neng)(neng)熱(re)水(shui)(shui)(shui)(shui)器(qi)和平板式太(tai)(tai)陽(yang)(yang)能(neng)(neng)熱(re)水(shui)(shui)(shui)(shui)器(qi)，主要以真(zhen)空(kong)管(guan)式太(tai)(tai)陽(yang)(yang)能(neng)(neng)熱(re)水(shui)(shui)(shui)(shui)器(qi)為(wei)主，占據國內95%的(de)(de)(de)市場份(fen)額。真(zhen)空(kong)管(guan)式家(jia)用(yong)(yong)太(tai)(tai)陽(yang)(yang)能(neng)(neng)熱(re)水(shui)(shui)(shui)(shui)器(qi)是(shi)由集(ji)熱(re)管(guan)、儲水(shui)(shui)(shui)(shui)箱(xiang)及支架等(deng)相(xiang)關(guan)零配件組成，把太(tai)(tai)陽(yang)(yang)能(neng)(neng)轉(zhuan)換成熱(re)能(neng)(neng)主要依靠真(zhen)空(kong)集(ji)熱(re)管(guan)，真(zhen)空(kong)集(ji)熱(re)管(guan)利(li)用(yong)(yong)熱(re)水(shui)(shui)(shui)(shui)上浮冷水(shui)(shui)(shui)(shui)下沉(chen)的(de)(de)(de)原(yuan)理，使(shi)水(shui)(shui)(shui)(shui)產生(sheng)(sheng)微(wei)循環而達到所需熱(re)水(shui)(shui)(shui)(shui)。
