This document presents a solar power plant project that generates 50W of DC power using solar panels and batteries. The solar energy charges a 12V, 7Ah lead-acid battery, which powers a string of 12 high-intensity LEDs acting as street lights. The system includes solar panels that provide 20V of power, a charging circuit to safely charge the battery without overcharging, and an LDR circuit to control the LEDs based on ambient light levels. The goal of the project is to utilize solar energy to provide off-grid street lighting.

3. Introduction
• The main objective of our project to generate
50watt DC power by using solar plate and utilize
as street light.
• Generated power is used to charge the battery by
using charging circuit and stored in the battery to
street lights.
• The street light we used combination of high
intensity LEDs in series connection.

6. Solar plates

7. solar plates
• It is main part of our project and it provide
electrical energy in dc form by photovoltaic
effect.
• terminal voltage 20volt.
• Short circuit current 3.3mA
• Length 500 cm
• Height 2.5 cm
• Width 300 cm
• Efficiency 80-85%

8. Battery

9. Batteries
• We used 12v,7Ah battery in our project
• In our project we used lead acid battery the
chargingdischarging 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.

12. Working of charging circuit
• A solar charger employs solar energy to supply
electricity to devices to supply electricity to
devices or charge battery
• This is not desirable to overcharge and under
discharge a lead acid battery.
• Both overcharging and under discharging can
badly damage the battery system.
• To avoid these both situations a controller is
required to attach with the system to maintain
flow of current to and from the batteries.

13. 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.
