GREENING TELECOM CELL SITES

ADVANTAGES OF EWIN’S TOTAL SOLAR POWER SOLUTION

Single Box Integrated solution easy to install and monitor

Life of Solar System is 25 Years with almost zero maintenance

Optimizes the energy from Solar, Grid, Battery and DG drastically reducing diesel consumption

Ideal for remote sites where conventional energy sources are not available/reliable

BUSINESS THREATS FOR TELECOM INFRA COMPANIES

Energy Costs for telecom operations raising

Diesel cost ever increasing

Due to frequent power cut telecom tower depend on Diesel

DG Generation Cost per unit is 3 times the Grid Cost per unit resulting in higher OPEX Cost

Diesel Pilferage additionally increasing OPEX/tower
