Do solar tracking systems cost more than a fixed array?

All solar tracking systems will cost more money up front than a fixed array, due to the complexity of the technology. With moving parts, they come with added maintenance costs. It’s also worth noting that due to the weight of the equipment, they are too heavy for most roofs, so are only suitable for mounting on the ground.

Who is array solar?

ARRAY is a renewable energy company providing time-proven utility-scale solar tracking solutions. Focusing on reliability, ease of installation, extreme weather risk mitigation, and fewer components.

Does a dual axis tracker cost more than a fixed array?

With a dual axis tracker, expected increase is another 5-10% on top of that, but this rarely justifies the added expense. All solar tracking systems will cost more money up front than a fixed array, due to the complexity of the technology. With moving parts, they come with added maintenance costs.

What is a solar tracker?

Ground mounted solar installations can use solar trackers to tilt the angle of solar panels throughout the day, maximising generation. They are typically used in large scale commercial or utility projects - not residential - as they come with added setup and maintenance costs, due to the additional moving equipment.

How do dual axis solar trackers work?

A dual axis system can tilt in two directions. One of the axes works as above, to maximise generation through the day. The other is oriented east-west, allowing a tilt north through south to optimise output during seasonal variations in the sun’s angle relative to the system’s position on the globe. What is the uplift from solar trackers?

How does an optimised single axis tracking system compare to a fixed system?

Let’s compare the output of an optimised single axis tracking system to a fixed system in London (both 10kWp): As you can see, there is one point around midday when the static system is optimally angled, but at every other time the tracker generates more power.
