If you need some idea of individual solar panel efficiency compare these relevant numbers.
The answers (far right) are the (maximum) Amps produced per square Mtr of each of the Solar panels total surface area.
Unisolar 64 Watt, per Square Mtr = 3.8 Amp ( LEAST efficient )
BP 80 Watt, per Square Mtr = 6.8 Amp ( average efficiency )
Sharp 123 Watt, per Square Mtr = 7.3 Amp ( MOST efficient )
When they are costed per *maximum* Amp produced (all sourced from solaronline) the relevant “per maximum amp” prices are as shown below.
Lowest price of the three . . BP = $108
Middle price of the three . . Sharp = $135
Highest price of the three . . Unisolar = $171
However when you take into account which panel gives more Amps per DAY (total amps - not maximum amps) into the equation the results are even more startling.
