Solar PV Panels with Tracking Device

Output of a solar PV panel system is at its best when the panels are facing the sun.  Solar PV tracking devices increase the time that the PV panels directly face the sun.  This substantially increases output.


Solar tracking devices can increase performance by 15 to 40% when compared to a fixed panel system. The increase in output is one of the benefits of installing a PV tracker.  Additional benefits can include:

The solar PV tracker is usually supplied as a 12, 18, 20, 40 and 80m² uniaxial or biaxial platform with monocrystalline or polycrystalline panels.


In additional to the solar PV tracking device, solar panels and inverter you need to cost for the mechanical and electrical works including a ground survey for the foundations.

As guide to what can be expected in energy terms, a 40m² solar tracker has a peak power rating of approx. 5 - 6kW dependent on the PV modules used.


The technical specification for a 40m² solar PV Tracker is detailed below

PV MODULES

The following predicted outputs and CO2 figures for a 40m² tracker are based on the UK and uses Birmingham as a reference point. They do not assume any shading effect.

Rated Peak Power  5.88kW

Number of modules  28

Predicted outputs (in the UK)  5656kWh

CO2 offset in kg/p.a  2432.08

   

MODULE B

Type  Polycrystalline

Rated Peak Power  5.28kW

Number of modules  24

Predicted outputs (in the UK)  4874kWh

CO2 offset in kg/p.a  2095.82


MODULE  C

Type  Polycrystalline

Rated Peak Power  5.04kW

Number of modules  24

Predicted outputs (in the UK)  4727kWh

CO2 offset in kg/p.a  2032.61


FOUNDATION

Type  Concrete pads, piers or screwpile

   

CONTROL SYSTEM

Type  Microprocessor based

Communications  Ethernet/Internet

   

SYSTEM CONTROL

All systems would have a wind sensor to track the modules in a horizontal position if the wind speed is higher than 40km/h. The modules will remain in this position, overriding any other settings, until the wind speed has fallen under this.


In case of a cable break at the wind sensor the modules would be tracked to a horizontal position.

The solar PV tracker solution is also available on a 12, 18, 20, and 80m² uniaxial or biaxial platform with monocrystalline or polycrystalline panels. You would need the tracker, panels and inverter, the mechanical and electrical installation including a ground survey for the foundations.
