The Motorized XL awning is identical to the Motorized model but projects out from the house 11'8". Depending on installation type and options, this awning has an average price tag of $4,000 to $7,500 installed. The XL model starts at 14' and goes up to 20' along the wall. So, the largest SunSetter awning is 20' x 11'8" and with all of the accessories like LED lights, roof mount brackets and an aluminum hood can cost up to $7,500. However, most awnings can be mounted on a wall, do not require the roof brackets or costly accessories and end up costing much less.
