The Sunshine Socialist Cinema held a presentation at IASPIS in Stockholm during the Open Studios 21-22 September. We made a brief introduction to the cinema setup and programming, screened the video A Ruda Road Movie by Marie Bondeson, announced our Open Call, and all of it through our new mobile Minimal Cinema. For more info on the Open Call, check the menu above.
The solarpanel produces 13 W per hour and charges a car battery. From the car battery and a 220 V converter we can then charge the internal battery of our pico projector.
The pico projector has an internal battery and holds a memorycard, which makes it an easily transportable filmscreening apparatus. It’s only about 13 x 6 x 2 cm in size. When the environment is dark enough, we can get an ok size on the projection, though obviously not as good as with our ordinary projector.
The solarpanel folds up into briefcase size. The whole setup cost us roughly 300 Euros for the projector plus 150 Euros for the power supply (solarpanel, battery and converter).
We got our brand spanking new projector set up. It’s got full HD resolution (1920×1080), and the lumens value (telling us how strong the light is) is 2000 ANSI. We absolutely adore it, but there’s a ‘but’.
Bit of free advice for those planning on starting up their own outdoor screenings here: if you’re on a tight budget, it’s better to sacrifice resolution for lumens – having for example 4500 ANSI lumens from your 1024×768 projector means you can start a little earlier in the evening, and the difference in resolution is only noticeable to the picky few.
On to building a shading stage for the screen now!
A 230 W solar panel providing power for a 270 W projector, meaning that from two hours of sunlight in the daytime we get one and a half hour of film projected at night. We plan on adding panels to the cinema from year to year, so the capacity will grow continually.
For those curious about the efficiency of solarpanels, a 230 W solarpanel at 1,5 squaremeters will produce about 900 times its’ wattage in a year, so:
230×900=207000 or 207 kWh. per year
(and that gives us 767 hours of projected film per year)
