As the telecom and wireless industry grows, mobile network operators, tower companies, and wireless internet service providers are expanding infrastructure in remote areas with unreliable grid power or no grid power at all. The status quo solution for inconsistant and off-grid telecom infrastructure continues to be diesel generators, which come with high fuel and maintenance costs and carbon emissions. Sun-in-one turnkey containerized solar cell tower micro-grids provides a clean, reliable, affordable alternative to diesel generators for the telecom industry.

Using solar energy is a reliable method of providing electrical power to telecommunication systems in remote places that are beyond the main electricity grid, for instance mountaintops and vast swamps, where power is unavailable or where it is impractical to install new power lines to remote locations. Solar energy is able to power many telecom systems including television and radio repeater sites, microwave repeaters, and RTU applications.

In order to calculate the solar array size for the location of the radio site, you can find the solar insolation for your location at http://eosweb.larc.nasa.gov. To determine the size a repeater or RTU site you first need to establish how much power the radio uses in both stand-by and transmit mode and the duty cycle, or the time the radio is operating during a 24-hour cycle. Then you need to determine the amount of solar radiation that is available at your radio site.  In order to calculate the size of the battery bank, you need to decide how long the radio needs to operate during extended periods of overcast skies.  All of this information will help to determine what size your system will need to be.
