 **Con:** Expensive per watt.  Newbies commonly underestimate [[electrical:solar:sizing|how much power is required]].  Voltage drop from long wiring runs.  Must be aimed at the sun((unless laid flat)), which would require repositioning every couple of hours.  Portability increases risk of theft.  Can be urinated on by dogs.((this really happens)) **Con:** Expensive per watt.  Newbies commonly underestimate [[electrical:solar:sizing|how much power is required]].  Voltage drop from long wiring runs.  Must be aimed at the sun((unless laid flat)), which would require repositioning every couple of hours.  Portability increases risk of theft.  Can be urinated on by dogs.((this really happens))
