Inflatable concentrators are helium-filled balloons used to collect the sun's energy. Each balloon can produce approximately 1 kilowatt of energy.
Inflatable concentrators are suspended between poles and are supported by cables. The concentrators capture sunlight and focus it onto photovoltaic cells. The sun’s heat activates the electrons in these cells, generating an electric current. The cells will produce some current as long as there is some sunlight and will function even when it is cloudy. However, no electricity is produced at night.
