#Solar power battery series#
high internal resistance means you can get large voltage drops across series cells.Low efficiency - may be as low as 50%, typically 60-65%.We suggest that potential alkaline users evaluate the economics and performance claims carefully to determine the suitability of any battery being considered." "Our experience with customers using alkaline batteries in stand-alone AE systems suggests that they may have as many drawbacks as advantages when compared to lead-acid type batteries. NIFE (NICKEL IRON)Įnergy storage density = 55 watts per kilogram Alkaline-type electric cells using potassium hydroxide as the electrolyte and anodes of steel wool substrate with active iron material and cathodes of nickel plated steel wool substrate with active nickel material. Not recommended for most solar or backup power systems. This makes them good for emergency/standby systems, but not for systems with a daily cycle. To put it another way, they have a long life in *chronological terms,* but not in *cycle* terms. My impression of traditional pocket plate NiCads-this is a turn of the century technology-is that they have many good points-low self-discharge, non-freezing, and so on-but their CYCLE LIFE IS NO BETTER THAN, IF AS GOOD AS properly chosen lead-acids. Non-standard voltage and charging curves may make it difficult to use some equipment, such as standard inverters and chargers.Very expensive to dispose of - Cadmium is considered VERY hazardous.NICAD (NICKEL CADMIUM)Īlkaline storage batteries in which the positive active material is nickel oxide and the negative contains cadmium.
They have an extremely long cycle life and high discharge and recharge rates. Lithium batteries have many advantages over traditional battery types. Intermediate batteries, such as the S460 and other batteries made by Surrette should last 7 to 12 years. Industrial-type batteries can last as long as 20 years with moderate care, and even standard deep cycle batteries, such as the golf car type, should last 3-5 years. The new AGM Battery technology has made a huge impact on lead-acid batteries, making it one of the best batteries to use in solar electric systems. The electrolyte is diluted sulfuric acid. The common automobile batteries in which the electrodes are grids of metallic lead-containing lead oxides that change in composition during charging and discharging.
