A 60-cell photovoltaic module typically measures about 65 inches by 39 inches (or roughly 5.4 feet by 3.25 feet), while a 72-cell unit is larger, averaging around 77 inches by 39 inches (approximately 6.4 feet by 3.25 feet).
[pdf] In 2007, Tuvalu was getting 2% of its energy from solar, through 400 small systems managed by the Tuvalu Solar Electric Co-operative Society. These were installed beginning in 1984 and, in the late 1990s, 34% of families in the outer islands had a PV system (which generally powered 1-3 lights and perhaps a few hours a day of radio use). Each of the eight islands had a medical cente. The Government of Tuvalu worked with the e8 group to develop the Tuvalu Solar Power Project, which is a 40 kW grid-connected solar system that is intended to provide about 5% of Funafuti 's peak demand, and 3% of the Tuvalu Electricity Corporation's annual household consumption.

[pdf] A 500 watt solar panel typically has a footprint of 27.5 square feet. This means that it is about 7.40 feet wide and 3.72 feet tall. The panel is made up of 144 half-cut monocrystalline cells, which are the solar cells that convert sunlight into electrical energy.
