How does this work with solar?...
Because the MacBook power adaptor is designed for 12V DC, it is ideal for use with portable solar power systems. All portable solar panels operate in what is defined as the 12v range. That is to say they are designed to charge 12v battery systems. That being said, there is one issue you need to be aware of...
Can I use the 12V MacBook power adaptor to connect a solar panel directly to my MacBook? No.
Why not?
Solar panels do not provide the level, or type of power output that inverters or converters can use to do their job. But batteries do. So the way to do it is to use a solar storage battery pack between your panel & this MacBook adaptor. The Solar battery can store power from your panel all day, and pump out the power your MacBook adaptor is asking for any time, day or night.
No AC adaptor needed...
This 100 Watt MacBook MagSafe adaptor works just like your MacBook's wall adaptor, but instead of plugging it into the wall, you plug it into your car or portable power kit (ie solar panel & battery pack system). Because you don't have to convert from AC, you save power.
Have you been using, or perhaps considering using an AC inverter to power your MacBook via its normal AC wall adaptor? An inverter creates household AC power from a car battery. A great idea, but not very practical when it comes to portability. First, you need a car battery to support it. Second, it means you have to carry more equipment, which by definition means greater complexity & potential for failure.
