One of your options is to consider vendors such as this: http://www.thinvent.in/products/solar/solar-computing, who make products such as this: http://www.thinvent.in/products/solar/oja-19-solar-dc-ups. These will allow you to run a lot longer on the same set of panels, because the overall efficiency of the system is higher. Dot matrix printers are fairly common in developing countries that still use paper systems extensively. This is because they offer the option to print 3-ply or 4-ply (yea, more trees destroyed), the consumable cost (both paper and ink) is the lowest, they are mechanically simpler to maintain, and deliver more print life than other technologies. They are also more dust proof than other printers (you simply open the lid and blow the dust out; also, given the amount of paper dust DMP's generate themselves, they better be dust proof). Therefore, you should be able to find a wide variety of DMP printers from Epson and other vendors. If they aren't available locally, fear not and import. They will rarely betray your trust and fail on you! Considering the heavy dependence on DMPs in developing countries, you will find consumables like paper and ink/ribbon for a many many years (definitely more than a decade, and you shouldn't be thinking longer than that at this point).

SoC parts that can deliver such high resolutions have become available only recently, thanks to the HDTV boom. Before that, ARM or MIPS graphics were usually limited to portable LCD or NTSC resolution. We at Thinvent are building such thin clients, using ARM processors. Using the TI OMAP3505, we deliver up to 2048x2048 resolution. Using the TI OMAP L138, we can deliver up to 800x600 resolution, for screen sizes less than 10". Especially interesting is the market for all-in-one thin clients, where the thin client is built into the LCD monitor, allowing quick installation.

I agree with parent. Why mark this troll? The truth is that a majority of the Indian public isn't as smart as what the average American encounters. In a democracy, it is always easy to mislead the public.
