Photovoltaic System for the Farm
The system
proposed is a 900 Watts Photovoltaic System that can provide up to 2 KW of electricity to the farm. The daily usage has to be budgeted to ensure that the
batteries storage is not fully discharged by excessive electricity usage.
System
Specifications:
900 Watts
Photovoltaic System (6 pieces of 150W Solar Panels)
Power
Inverter, 24Vdc to 230Vac, 2,500 Watts
Lead Acid
Batteries 12Vdc 200 AH – 4 pieces (Operating at 24 Vdc)
Budgeted
Daily Energy Usage: approx 2,600 Watt-Hour per Day
Standby
Battery Storage: 3 days
The Schematics for the Photovoltaic System is shown
below.
The estimated energy usage for the farm
based on their daily operations using the following electrical equipment and appliances:
- Water Pump (500 watts) uses 3 hours daily
- LED Lamps (10W x 5 pieces) uses 6 hours at night
- Fan (40W x 2 pieces) uses 10 hours at night
- Spot Light (10W) operate 12 hours at night for security
If the farm restricts the energy usage to the
above duration, the photovoltaic system will be able to provide their daily
energy needs.
The ampere meter shows the solar charging current of 18.7 Amps into the lead acid batteries.
A change-over switch between generator and solar allows easy switching between the two systems.
Donation
of the Photovoltaic System.
- Photovoltaic System Cost – SGD 4,500
- Tools (Hammer Drill & Battery Operated Hand Drill) – SGD 160
In October 2018, I bought a new inverter online, 2500W pure sine wave solar power inverter DC 12V 24V 48V to AC 110V 220V digital display. It cost me SGD$213.73.
Manage to get someone to bring over and install the inverter. The system is working again.
