Absorbed Glass Mat (AGM) batteries are seeing more and more use in solar electric systems as their price comes down, and as more systems are getting installed that need to be maintenance-free. This makes them ideally suited for use in grid-tied solar systems with battery back-up.
Because sealed AGM solar batteries are completely sealed, they:

AGM's are also well suited to systems that get infrequent use, as they typically have less than a 2% self discharge rate during transport and storage. They can also be transported easily and safely by air. Last but not least, they can be mounted on their side or end, and are extremely vibration resistant. AGM's come in most popular battery sizes and are even available in large 2 Volt cells for the ultimate in low-maintenance large system storage.
Because of their high cost when first introduced to the market, AGM batteries were mostly used in commercial installations where maintenance was either impossible or more expensive than the price of the batteries. Now that the cost is coming down, they are seeing use in all types of solar systems - clearly some of today's owners feel the advantages of AGM outweigh the price difference and maintenance requirements of flooded lead acid batteries.
