Fixed Solar Panels Vs Tracking

Residential and small capacity commercial or industrial rooftop solar panels and solar water heater panels are usually fixed often flush mounted on an appropriately facing pitched roof.

Fixed solar panels vs tracking.

Lastly tracking systems are more expensive to maintain over the 25 year life of a system. This research is an empirical financial assessment of the benefit of using a dual axis sun tracker versus a fixed flat position as well as a comparison of the performance of the two panels under such settings. The roi of a pv tracker vs. When solar trackers are coupled with solar panels the panels can follow the path of the sun and produce more renewable energy for you to use.

In a fixed form their efficiency is low since the panels will be tilted in a particular angle whereas in a tracking system the panel is made to move either in single axis or dual axis. Compared to a fixed mount the additional cost per watt or premium to track is 1 33 per watt 2 24 0 91. Possible types of installation can be shown on the picture. Trackers increase the production of a site by more than 15 to 25 over fixed tilt.

Fixed systems can generally accommodate up to 20 slopes in the e w direction while tracking systems typically offer less of a slope accommodation usually around 10 in the n s direction. Fixed rack system 3 vs tracked system 4 cost breakdown the tracking price is 2 24 per dc watt. Advantages of fixed mounts over trackers include the following. Only x axis tracker only y axis tracker xy dual axis tracker and azimuth tracker systems during the design consider tracker system has higher initial investment cost than non tracking system and maintenance cost the biggest advantage is producing more energy in the same area tracker system designer says that up to 30 more energy.

Fixed tracking systems offer more field adjustability than single axis tracking systems. The maximum output of the panels is achieved when the panels are perpendicular to the sun s rays. An additional 20 of acreage for tracking systems is a good rule of thumb for checking the economics. That increases the installed cost for a tracked pv system from 8 63 to 9 96 per dc watt.

Solar trackers are usually paired with ground mount solar systems but recently rooftop mounted trackers have come onto the. Benefits of fixed pv systems. In a world of rapidly decreasing prices for solar ppas increased power production is critical in helping project owners achieve a viable roi.
