This DIY solar energy kit is designed with solar education in mind and is perfect as a solar power demonstration for a classroom. The important components of the classroom edition are the digital meters. This is where you can learn about voltage, current, amp-hours and more.
The digital meter will give you the real-time voltage and current of your system. Watch the voltage increase when the battery is charging. Meter tells you how many amp-hours you have generated during the day of sun. Watch it go down when you are powering devices (or charging smartphones etc.). Includes a 12V Desk Lamp and a 12V 7 Watt LED bulb for the lamp. Also includes a 100W DC to AC inverter and a Stainless Steel 12V DC outlet with USB adapter. The kit does not include battery. We recommend using an 18AH Sealed battery or a 32AH sealed battery. You can also use a 12V Deep cycle marine battery purchased locally, but we recommend one of our sealed batteries if you are locating the battery inside a classroom.
The kit includes:
- 20 Watt Polycrystaline Solar Panel - Solar charge controller
- 100W DC to AC inverter
- 12V DC Stainless Steel outlet with USB adapter
- 12V DC Desk Lamp (color may vary)
- 12V 7W LED Bulb
- Fuse holder with fuses
- 2 Digital loggers displays voltage and current for solar and load
- All Wiring and connectors
- Complete instructions
You can mount the digital meters and 12V outlet on a piece of plywood and label each meter. Or use a wooden crate, or plastic cooler. Just keep the wires and battery in "the back" and have the meters and outlets available to see and use. Be creative! Optional: Wall/Pole mounting hardware, 12V DC 15W CFL Bulb (to compare power usage to LED bulb).
