This is an interesting topic, Q, do bi-facials really work? A, it depends,
Solution, low profile on a roof may not so much its all about reflectivity
so higher off the ground(roof) the better. A parking lot canopy might see a
measurable improvement if the parking lot is a light reflective color, dark
not so much, single rows vs large arrays also better, further north from
the equator can help, snow on the ground will help, bottom line is, it is a
real hard number to qualify until you can compare your actual location, I
sell them and state very clearly what ever you get is a bonus that's all. I
know some many differ from this but telling someone they will get X% back
is going to spell disaster, it will be a hard sell to tell the property
owner that he must keep his panels and roof clean to gain any additional
