The Solar Portables Business, Inc. (dba P3Solar) was originally started by Global Solar Energy in 2001 and developed its first lightweight P3 military grade portable solar charger for the United States Marine Corp (USMC). This led to a contract with the United States Army Communications-Electronics Command (CECOM) for development of the P3-55 watt solar charger as part of the Bren-tronics Soldier Photovoltaic Portable Power Pack (SP4). The SP4 evolved to the Rucksack Enhanced Portable Power System (REPPS) and today includes the P3-62 watt solar charger.
In 2008, the United States Marine Corp awarded the Solar Portable Alternative Communications Energy System (SPACES I) contract to Iris Technologies which developed a kit including two P3-62w solar chargers. In 2012, the Marine Corp awarded Iris Technologies a follow on contract for SPACES II (next generation) which includes two P3-62w solar chargers per kit.
Global Solar Energy and now P3Solar has shipped over 50,000 P3 solar chargers to US Military and Allied Forces around the world and continues to supply a line of P3 products including; the second generation P3-20W, P3-30W, P3-60W, P3-100W, and P3-125W available in Desert (Tan) and Woodland (Green) camouflage, Multicam all purpose camouflage and Black. This generation offers higher efficiency and lighter weight.
Derived from the military version a series of commercial charges are offered in rollable format providing a more cost effective solution. These come in 50W, 80W and 200W versions in Saffron yellow or Coyote tan. Custom colors available for large orders.
