A stand alone solar photovoltaic street lighting system, comprises of a 11W / 18W compact fluoresent lamp, Low maintenance lead acid battery or Maintenace free lead acid battery, PV module(s) Control electronics, Interconnecting wires/cables, Pole, Module(s) mounting hardware, Battery box, instruction and maintenance manual. The system designed to switch ON the system at dusk, operate throughout the night and switched OFF at down, automatically.
Electronic Protections:
- Adequate protection is incorporated under no load conditions e.g. when the lamps are removed and the system is switched ON.
- The system has protection against battery overcharge and deep discharge conditions.
- Fuse provided to protect against short circuits.
- A blocking diode provided as part of the electronics to prevent reverse flow of current through the PV module(s)
- Full protection against open circuit accidental short circuit and reverse polarity is provided.
Mechanical components:
- Galvanized Metallic frame structure fixed on the Pole to hold the SPV Module(s). The frame structure will have provision to adjust its angle of inclination to the horizontal between 0 to 90 deg. So that it can be installed at the specified tilt angle.
- The pole is of mild steel pipe with a height of 4 meters above the ground level after grounding and final installation. The pole will have the provision to hold the all weatherproof lamp housing.
- A vented acid proof and corrosion resistant (Galvanized) metallic box for outdoor use provided for housing the battery
