Why does an axis solar tracker produce more than a fixed structure?
- By tracking the sunlight throughout the day, the sun’s rays hit more directly, around 20 or 25% extra production per panel.
- The panels that are manufactured are usually bifacial, and with trackers the light from the other side is better used, around an extra 10% of production per panel.
When to put 2-axis trackers and when to put single-axis trackers?
In summary, it would be: if you want maximum production per panel, 2-axis trackers are recommended, however, if you want maximum production per km2 of land, single-axis trackers are recommended.
In medium or large plants, currently one always opts for axis trackers, since the price of the panels is cheaper, they require less maintenance and it is very scalable with large areas, more panels can be placed without being shaded, so the use of space is much higher.
In solar concentration, which requires high precision, or any other use in which great precision is desired in the orientation of the panels towards the sun, it is preferable to use 2-axis trackers, also in research and investigation in different fields.
What types of terrain is it recommended for?
Any land that is suitable for a fixed structure will also be suitable for axis trackers. The optimal land is one that has a south-facing slope. It is also optimal with agricultural land if you want to combine cultivation + solar production.
What maintenance does an axis tracker need?
- Scheduled maintenance: Just grease the gears and friction parts once every 6 months. This may take 12 minutes for one person per tracker.
- Non-scheduled maintenance: After a few years it may be appropriate to review the possible occurrences of rust so as to apply an anti-rust treatment. Control, repair and replacement of damaged and parts failures. Trackers Feina can take care of the maintenance for a small annual cost.
What is the useful life of an axis tracker?
More than 30 years in both the metal structure and the electronics.
What panels is it compatible with?
Any type of solar panels are compatible with Trackers Feina trackers, as long as they do not exceed the permitted area.
What control options does it include?
The trackers incorporate automatic control, and manual control. Along with the trackers you will receive a manual with their operation.
