I have a 200kW flat roof, ballast-mount solar installation and I need to evaluate the cost-benefit analysis for using a 10-degree tilt versus a 5-degree tile (or even a 0-degree tilt). How can I calculate the added output that my system would generate with an optimized tilt angle? How would that benefit compare to the extra racking cost for going with a higher-degree tilt?

Send your location (address or lat / long) and I can tell you the best tilt angles (annual, adjustable for seasons), average solar insolation. information@solarworx.netIf you have shading data, I can include that too.PS: This is not using SAM by NREL.
