Question by : Solar Power………..?
What controllers and all that stuff do I need for these solar panels.

Please list all the circuitry and batteries and every thing. Oh and the the batteries will be rigged up to a big electric motor so please leave information on how to wire the batteries to the motor…
THANKS!!! 10 POINTS!
I need about 150 volts worth of these solar panels by the way

Many solar panels wired in parallel, 12 volt solar regulator, 12 volt battery e.g. 30 Ah, 240 volt inverter, autotransformer that can go down to 150 volts.
There are many parameter to the electric motor missing. AC or DC, current needs for full load. How many watts the motor uses and the number of hours required will influence the solar panel, regulator and inverter specifications.

Solar panels, like batteries, can be wired in a series or in parallel. In parallel they increase the potential amperage while the voltage remains the same. In series the final voltage is increased. http://www.countrysidemag.com/issues/90/90-1/Rex_A_Ewing.html

From this and other questions it seems as if you are planning a mobile photovoltaic array. This has an additional problem. Present photovoltaic systems are from 8 to 22% efficient. When placed on a house they are carefully placed to gather the maximum amount of sunlight. To gather even more sunlight they could be placed on a tracking mechanism but the efficiency of photovoltaic panels is so poor that the expense of the tracking mechanism is not considered worthwhile.
But a photovoltaic array on a mobile vehicle will almost always be aimed wrong. This substantially reduces its efficiency. Additionally the amount of energy that could be gathered would be insufficient to power a heavy vehicle on the sun’s energy alone. Solar racing cars are extremely aerodynamic and very light.

The guy put solar panels on a Datsun.
