MANHAR.

3. Solar power system is one of renewable energy
system which uses PV modules to convert
sunlight into electricity.
The electricity generated can be either stored
or used directly.
Solar PV system is very reliable and clean
source of electricity that can suit a wide range
of applications such as residence , industry
,agriculture etc.

4.  THIS PROJECT PLAYS AN IMPORTANT ROLE IN THE AREA’S
WHERE THERE IS ABUNDANT SUNLIGHT AND LARGE RURAL
POPULATION WITHOUT PROPER INFRASTRUCTURE.

5. 1.SOLAR PANEL: converts sunlight into Dc
electricity.
2.INVERTER: converts DC to AC for
appliances.
3.BATTERY: stores energy for supplying to
electrical appliances when there is a demand.
4.LOAD (APPLIANCES): TV, LIGHTS etc.
5.CHARGE CONTROLLER.

7. “WE ARE CONSUMING A ONE 20 WATT
BULB FOR 4 HRS A DAY”
1. POWER CONSUMPTION:
Total Appliance used = 20 watt X 4hrs
=80 wh/day.
Total PV panel energy needed = 80 X 1.3
= 104 wh/day.

9. Part Total Qty. Description
C1, C2 68 uf, 25V Tantalum Capacitor
R1, R2 10 Ohm, 5 Watt Resistor
R3, R4 180 Ohm, 1 Watt Resistor
D1, D2 HEP 154 Silicon Diode
Q1, Q2 2N3055 NPN Transistor
T1 24V, 15A Center Tapped
Transformer.

10. Total Wp (peak watt) PV capacity needed
104/2.93
= 35.49 Wp.
No of PV Panel needed = 35.49 Wp/10
= 3.5
=4 module.
(Panel Generation factor = 2.93)

11. Total watt of the appliances = 20 watt.
 For safety inverter should be bigger 25-30%.
The inverter size should be about 25watt.

12. • Total appliance used = 20 X4 = 80 watt/day.
• Nominal battery voltage = 12 volt.
• Days of Autonomy = 3 days.
• Battery loss= 0.85
• Depth of discharge = 0.6
Battery Capacity (Ah)={(total watt-hrs per day used by
appliance) /(0.85 X 0.6 X nominal battery voltage)} X
Days of aotonomy.
= {(20 X 4)/(0.85X0.6X12)} X 3
= 39.21 Ah.
So battery should be rated 12 v 39.21 Ah for 3 days of
autonomy.

14. LIGHT WEIGHT.
EASY TO CARRY.
LOW COST.
COMPACT.
NON POLUTING.

15. SOLAR PANNEL - Rs.1000.
BATTERY - Rs.500 .
ELECTRICAL COMPONENTS – Rs.500.
BODY - Rs.200.
TOTAL = Rs.2200.
