Solar set with 19V outlet for notebooks

Solar set with 19V outlet for notebooks

The 19V outlet of the photovoltaic set for notebooks increases the efficiency versus a 12V outlet and a car adapter for the notebook. My ASUS UL30A is set to maximal screen brightness like usual when working outdoor at full sunshine. 20.2 V times 0,71 A gives 14,34 Watt.

Batteries for 12V solar power supplies
	Notebooks can be easy supplied with solar energy. From solar electric power for a day on the beach, for expeditions up to island solutions for houses without power grid connection.

Notebook outdoor all the day

Complete system for the solar power supply of notebooks and longer run time by an external battery.

scope of delivery 85W solar set
After You have taken out the foldable 20 Watt photovoltaic of the box, You find below: Left top: control unit with 66 W lithium-ion battery, middle top: 12V LED lamp.

Charge solar set by a notebook power supply
The 85W solar set can be charged by any notebook power supply as far as the plug fits and the power supply can deliver 60 W.

Test photovoltaic set for notebooks at the rivulet
After 15 years hauling a lead battery, after 2 years too weak NiMh buffer battery. July 4th 2012 starts a new age of notebook outdoor usage.

Solar charger for camera batteries
Most chargers for batteries from video- and digital cameras can be used with 12V. At the 12 V output of the solar set is a car-socket.

Efficiency of AA battery charger
At calculating the energy usage, it's easy to look over the efficiency of diffeeren processes. Or who would have thought, that this AA battery charger just needs 10 W?

Test with Belkin 40 W 12V DC 100-240 AC power supply
The Belkin F5L065 is speciall for netbooks and economical notebooks like my mein ASUS UL30A. Here the conversion loses compared to the direct 19V outlet.

Test with Vanson 70W car adapter
The Vanson SDR-70W is designed for normal notebooks with a higher electric power demand. Compard to the direct 19V outlet of the solar set.

20 W foldable photovoltaic
It's July 4th 2012, the photovoltaic is full in sunshine, but 13.47 V times 0.86 A are only 11,58 Watt. Not optimal oriented towards the sun, a little bit warmer.

34 W foldable photovoltaic
The 85 W control unit stands more than a single 20 W modul. Here I connect my foldable 34 W Unisolar from 2005 and the new foldable 20 W foldable from the solar set together.

Battery full shows MPPT procedure
There had been just 13.86 V and 2.27 A. Suddenly, the display changes to 17.49 V and 1.13 A gives 19,67 Watt. This change is the proof for the MPPT procedure.

What does the MPPT with 12V AA Mignon cells?
From 2010 until today, I used 12 AA Mignon rechargeable batteries for my solar power supply of the notebook. Here an experiment what happens when this batteries are

Length of cable is not enough
The distance between a place in the shadow to work and a sunny place for the photovoltaic to deliver electric power can be larger than thought.

Sunshine early in the morning
6th July 2012. A little bit sunshine through the tree-tops. I have all 3 photovoltaic modules with meh, becuase I want to test using 2 notebooks.

First full sunshine in the morning
41 minutes later, the sun is now above the trees and the solar yield is first times greater than the demand from notebook and cell phone. 1.59 A times 13.8 V gives 22 Watt.

3 photovoltaic modules to compare
One hour later 8:40 am, it becomes cloudy. Opportunity to compare all3 modules, how much they deliver at cloudy sky and still not so high standing sun.

Run several notebooks by the sun
As long as the notebooks do not charge the internal batteries, 85 Watt are enough for some economic notebools. Here is my ASUS UL30A connected by a car adapter to the 12V outlet.

Supply from the sun
While I make my test with 2 connected notebooks, all 3 photovoltaic modules, deliver together 2.74 A at 14.2 V. 39 Watt are little bit below the demand.

Change the battery in a lyceum
You have 2 batteries for Your notebook, but how do You exchange them, when You sit in a liceum with no plug in reach?
