A novel sight is becoming increasingly common in<br />
low-income households around <strong>the</strong> world. Tired <strong>of</strong><br />
waiting <strong>for</strong> a reliable grid connection, people are signing<br />
up <strong>for</strong> solar home systems (SHS). For rural communities<br />
without grid power and urban households with<br />
intermittent power, a solar home system provides safe,<br />
af<strong>for</strong>dable energy.<br />
Although solar pho<strong>to</strong>voltaics12 have been around <strong>for</strong><br />
decades, recent developments in business models and<br />

Solar PV components are expensive, especially solargrade<br />
silicon. Developed country demand, driven by<br />
government subsidies, tax incentives, and a burgeoning<br />
desire <strong>of</strong> rich world households <strong>to</strong> reduce <strong>the</strong>ir impact,<br />
has absorbed <strong>the</strong> capacity <strong>of</strong> solar PV manufacturers.<br />
Solar PV manufacturers have focused on consumers in<br />
12 From US Department <strong>of</strong> <strong>Energy</strong>: "Pho<strong>to</strong>voltaic (PV) systems…convert sunlight directly <strong>to</strong> electricity by means <strong>of</strong> PV cells made <strong>of</strong> semiconduc<strong>to</strong>r<br />
materials….When certain semiconducting materials, such as certain kinds <strong>of</strong> silicon, are exposed <strong>to</strong> sunlight, <strong>the</strong>y release small amounts <strong>of</strong> electricity.<br />
This process is known as <strong>the</strong> pho<strong>to</strong>electric effect…A PV system is made up <strong>of</strong> different components. These include PV modules (groups <strong>of</strong> PV cells),<br />
which are commonly called PV panels; one or more batteries; a charge regula<strong>to</strong>r or controller <strong>for</strong> a stand-alone system; an inverter;… wiring; and<br />
mounting hardware or a framework."<br />

reality <strong>for</strong> millions <strong>of</strong> homes.<br />
SHS have been slow <strong>to</strong> scale <strong>for</strong> low-income households<br />
due <strong>to</strong> a combination <strong>of</strong> challenges:<br />
� Expensive material and inappropriate systems<br />
� Market dis<strong>to</strong>rtions due <strong>to</strong> subsidized or free systems<br />
� Lack <strong>of</strong> financing <strong>for</strong> consumer purchases<br />
� Need <strong>for</strong> trained technicians <strong>to</strong> install systems<br />
