Solar Batteries

Batteries are required for many solar installations (both grid-tied and off-grid) to store DC energy generated by the solar collectors. Most solar batteries are deep-cycle cells, allowing them to be less susceptible to degradation as a result of regular cycling. SolarPanelsOnline carries reliable flooded, absorbed glass mat (AGM) sealed lead acid and gelled electrolyte (GEL) sealed lead acid batteries by Concorde, Deka Solar, Hawker, Iota, MK Battery, Rolls, Samlex, Trojan Battery and Xantrex.

AGM batteries are completely sealed, which prevents spills and corrosive fumes. These maintenance-free batteries are ideally suited for grid-tied solar systems and although they used to be relatively expensive, their price has come down in recent years, making them a great choice for most homeowners.

Gel batteries are lead acid batteries made with a highly viscous gelled electrolyte. GEL batteries must be charged at a slower pace than AGM batteries, but are well-suited for systems where discharge rates are less than severe.

Flooded batteries, also known as wet cells, are the most common lead-acid battery-type in use today. They offer long-life and the most size and design options for many different uses.

You can also find a full complement of battery enclosures and battery cables and even powerful battery chargers for your off-grid or on-grid PV solar energy array.
