小菜一叠， 看看给我的报价：

Your balcony  is not a simple straight across tracking system installation.

 

It consists of 4 curved track sections which are made specifically for your balcony configuration.

This alone accounts for $1500.00 of the price.

 

The installed price for units of your type is $23.79 per square ft. = $6,282
