Spotted at Hackaday is this open source solar power generator design, which is "designed to replace conventional diesel generators".
The device does use some proprietary components, but the entire design is open source. It contains solar panels, of course, as well as storage capacity and an inverter.
...
The design is modular so you can pick and choose what you want. It also is portable, stackable, and easy to transport. The team claims they generate 900W of solar power and can store 4 kWh. Because of the storage device, the peak power out is 1600W and the output is 230V 50Hz AC.
Instructables has complete build instructions, published under the CERN Open Hardware License, as well as more detailed technical specifications.
The project homepage has additional background, and summarises the objectives of the design:
It is made for off-grid energy production in remote areas, outdoor events, refugee camps or in case of emergency situations.
The SunZilla system combines four unique features: it's open source, portable, modular and easy-to-use with a plug-and-play approach.

The listed stats say it can run 2 x 160 litre fridge for 100 hours. That should get you through a few dark days, and sounds like the panels have more than enough excess capacity to top the battery up on bright days, especially if you cut that fridge count down to 1.

The only link with pricing was instructables. It is 1000Euro or about and not even in the ballpark of running a fridge for days.
