Staff use the mobile solar kit as a power source on the farm and at field events. The kit has been used to demonstrate the workings of solar electricity to hundreds of adults and children on field trips and at farmer’s markets, environmental fairs, and other agricultural events.
The solar demo kit consists of the following items:
• 2-55 watt BP Solar modules (110 watts total power)
• 2-12 volt 105 amp-hour batteries (210 amp-hours total storage capacity)
• 1200 watt power inverter for converting 12 volt direct current stored in the batteries to 120 volt alternating current.
• A charge controller to regulate battery voltage
• A 12 volt water pump to run directly from the solar array
• Guages to monitor battery charge and power generated by the solar array.
All components are mounted on a convenient, portable cart for easy transport to field events and around the farm.
One of the most practical uses of solar electricity is in remote power situations.
The solar fence charger is used to electrify a mobile fence used for chickens. Rather than keeping the farm’s laying hens penned up in a building or yard. The farmers move them around, enabling the chickens to consume fresh plants.
The staff has set up a wind and solar electricity demonstration at the main public building, The system consists of:
• An 800 watt wind generator mounted on a pole attached to the farm silo
• 330 watts of solar power (2-165 watt modules)
• 4 350 amp-hour, 6 volt batteries (provides 700 amp-hours of storage at 12 volts)
• A charge controller, safety disconnects, and monitoring gauges
• A 1200 watt power inverter for converting 12 volt direct current to 120 volt alternating current (to power household devices)
• 12 volt DC lighting
• 120 volt AC compact fluorescent lighting
