當前光伏系統用儲能電池最常用的是鉛酸蓄電池，此外極少部分也用鎳福（Ni-Cd）與鎳氫（Ni-MH）電池。離網光伏系統中，要能進行持久連續的能量供應，必須使用儲能電池。太陽能電池受光照時間、光照強度等自然條件的影響，其發出的電能并不能平穩地供給用電器的用電需要，通常用電池進行能量儲存、能量調節后，才能滿足光伏系統儲能裝置在市場應用的要求，光伏系統離不開蓄電池的配用。www.meifuwang.cn
The photovoltaic system with energy storage battery is the most commonly used lead-acid batteries, in addition a few also use Ni Fu ( Ni-Cd ) (Ni-MH ) and nickel metal hydride battery. The off-grid PV system, to can lasting continuous power supply, must use the energy storage battery. Solar cell by light, light intensity and the effect of natural condition, which can generate electric power and cannot be smoothly supplied with electrical power, usually with battery energy storage, energy regulation, in order to meet the photovoltaic system energy storage device on the market application requirements, photovoltaic system without battery equipped with.
