How do you get electricity to the billions of people living without it today?
Our approach was to develop a simple, affordable solar kit providing basic features that will address the challenges faced by the underserved. To make this scaleable, we plan to empower, through education and training, local communities to build and deliver these kits. This will provide local jobs and create a sustainable process for addressing energy poverty.
1) 25W solar panel
2) 100Whr controller/battery
3) Lights - Two 3W LED
4) Fan - One 2.5W
1) 2W radio
2) 3Wh rechargeable flashlight
To determine their usage, we set the regulator to use about 60% of the battery to extend the life so they can use about 60Whr in the evening.
Of the 60Whr of useable capacity, a typical case may use 51Whr.
4 hours of light – 3W * 2 bulbs * 4hr = 24Whr
2 hours of radio – 3W * 2hr = 6Whr
4 hours of fan – 2W * 4hr = 8Whr
Charge 2 phones = 10Whr
Charge the USB flashlight = 3Whr
