Introduction

• The main objective of our project to generate50watt DC power by using solar plate and utilizeas street light.

• Generated power is used to charge the battery byusing charging circuit and stored in the battery tostreet lights.

• The street light we used combination of highintensity LEDs in series connection.

Solar plates

solar plates

• It is main part of our project and it provideelectrical energy in dc form by photovoltaiceffect.

• terminal voltage 20volt.

• Short circuit current 3.3mA

• Length 500 cm

• Height 2.5 cm

• Width 300 cm

• Efficiency 80-85%

Battery

Batteries

• We used 12v,7Ah battery in our project

• In our project we used lead acid battery the

charging\discharging efficiency of this battery is 50-95%

• To maintain the voltage level and power supply rate of the

system.

• A battery bank connected parallel to this system takes

care of that.

• The battery is charged by solar electricity and this battery

then feeds a load directly or through an inverter.

Charging circuit

Charging circuit

Working of charging circuit

• A solar charger employs solar energy to supplyelectricity to devices to supply electricity todevices or charge battery

• This is not desirable to overcharge and underdischarge a lead acid battery.

• Both overcharging and under discharging canbadly damage the battery system.

• To avoid these both situations a controller isrequired to attach with the system to maintainflow of current to and from the batteries.

Load

• 12 High intensity LEDs are used in our project

as load.

• Combination of 4 LEDs are connected in

series.

• Rating of every LEDs 3 volts.

Advantages of Solar Energy

• Clean

• Sustainable

• Free

• Provide electricity to remote places

Disadvantages of solar energy

• Less efficient and costly equipment

• Part Time

• Reliability Depends On Location

• Environmental Impact of PV Cell Production
