Liter of Light has been going through several refinements to make sure that the solar bottle light is done properly. We are sending this video for people wanting to build.

Some important lessons we learned :
- Use always a sheet metal scissors for cutting round edges to make sure that the hole in the roof is as close to the diameter of the bottle as possible ( you will have to glue the underside!)
- Sand very well the bottle till the shiny part is removed. The glue will not stick on to the plastic
- The top portion where the bottle meets the plastic is where most leaks happen. You must use a tougher glue than just an elastomeric sealant. Use a SikaFlex 11FC glue or an epoxy sealant to make 100 percent sure this is sealed properly.
- Always use PET soda bottles ( 1 L, 1.5 L, 2 L ) to make sure that it does not easily break. DO NOT USE plastic water bottles.
- Use a guide in cutting the roof that assures that the bottle fits snugly though the roof. You will have to seal this from the underside so don’t freehand cutting the hole.
-Use a guide plastic bottle filled with cement to open up the cut metal sheet so you will not have to damage the empty plastic bottle.
- Seal the underside of the bottle cap once you placed distilled water and bleach to prevent leaks.
-Place a 1 1/4 inch pipe covering the top and around the plastic bottle cap as this is prone to cracking with the infrared rays of the sun.
Good luck and be safe installing a Liter of Light.

Sunny winter day in south australia, 2.8 kilowatts coming from solar panels on the roof. I don’t like my power company…
