Building this project will allow you to use a Raspberry Pi as a 'headless' controller and status monitor for your USB bitcoin mining devices (ASICMiner Block Erupter). The project incorporates an LCD to display hashrate, error rate, share data, network difficulty, mining duration, & current exchange rates.
Convert what would be wasted sunshine collection into digital digital currency (BitCoin or Litecoin) and sell the digital hashes currency on for real cash

You can integrate these into the back of the solar panel and the only cable coming from it is a 350 meter LAN Ethernet cable so it can join a mining pools to work together with others to get more bit coin hashes
Every time the sun comes out / or if there is enough 5V amps on overcast days the Buck Volt Converter Step Down will give power to the Pi + ASICMiner Block Erupter it boot up and start mining if the solar output drops below 6v it will shut of power to the pi
The DC Buck Volt Converter take the very large wide voltage 5v upto 37.5V range output of the 250W and downs it to 5V 2A For the pi + 5V 2A for the 4x ASICMiner Block Erupter (500mA each)
this leave 4A to spare for Charging a 12V 20Ah Motorbike Lithium Ion Battery

can take max charging current: 28A with a lead acid charger
via a second DROK® 8A/100W 8-40V to 1.25-36V DC Buck Volt Converter Step Down 12V Car Power Supply Voltage Regulator in parallel with the first (however the fist one has a diode)
the battery runs a 12v time switch

20Ah is a long time with a pi you looking at days before it runs too low
The money you make per month with 1x Pi and 1x ASICMiner Block Erupter (330MH/s) is £4 a month (in us that $8 USD) with 4x its £16 (USD $32) if it on 24/7
Due your ASICMiner Block Erupters are 2.2-2.7 GH/s you will make more in less time for the hours the miner has power from daylight
