In 2008, the United States Marine Corps 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 a rollable format providing a more cost-effective solution. These come in 50W, 80W and 200W versions in Saffron yellow or Coyote tan.  Custom colours are available for large orders.
