The Solar Hub is the basic building block of HSSi’s rural operations. Located in municipalities closest to priority off-grid markets, each Solar Hub has a service territory within which it provides partners and clients with ongoing sales, marketing, logistics, training, and maintenance support. These Hubs are not retail outlets, but focus on reaching markets in remote barangays and sitios in the market cluster. These solar service centers, located in major municipal centers, are composed for a core staff of 4 to 7 people (Solaristas and technicians), a physical office space, and installed and portable solar demonstration units.
