Lower build cost per MWhr of your solar farm over the life of our product, Guaranteed9
Reduce Build Cost per MWhr. CQSola 1500V Solar Power Controllers convert power at 99.2% - 99.5% efficiency, and allows each panel to operate separately. This captures power from each panel individually, and combines to each string without power loss.
Panel-level MPPT's track and fully return to the Maximum Power Point after shading typically within 2 sec. 9Guarantee subject to additional terms and conditions, guarantee not available on all farm designs, indicative build cost without CQSola Equipment over 30years is $36USD/MWHr on the DC Side vs $30USD/MWHr with CQSola Equipment on the DC Side of the inverter

5%-25% additional power output4, same panels
1 Second Data collection, on every panel
Get 100% clarity over your solar farm. Know exactly what energy is getting outputted at every point in time. Isolate your data down to a single panel, any any second of the day. If a panel fails, needs cleaning, or starts to show electrical signs of silicon cracking, you can track it to the panel.
Almost no loss with a single panel outage
With our Solar Power Controllers in your solar farm, the maximum power will be preserved at all times. If a single panel fails, you don't lose all power from the string; just the one panel
Remove central MPPT's from design
Maximum Power point tracking is conducted by our power controllers , and able to feed directly into the inverter. Central MPPT's can be removed from the design, and replaced with CQSola Solar Power Controllers at the panel. This allows each Panel to track to Maximum optimisation and provide overall better efficiency.
Replace individual panels at any time
Each solar power controller can be set to a maximum operating voltage, so older panels can be mixed in with new panels on the same string. No bother to keep an excess of the same panel in storage
In natural disasters, such as floods, cyclones or electrical storms, solar farms traditionally can't be shut off. CQSola OS1000 solar power controller allow each string to be turned off remotely as needed. Entire system solar farm is possible within seconds of Emergency Shutdown switch being activated.
No-clipping between controllers
Anti Clipping technology actively takes voltage head-room from underperforming or shaded panels, and applies it to the best performing panels in real time. Never clips any power, and always remains safe.

Data without Ethernet cabling2 or Wifi disturbance
We've added an in-line modem to pass all the data over the power cables. High quality, reliable data, without the extra hassle, just plug in the solar power controller, and comms start up.
Reduce lost power from aging panels
As your solar farm ages; power output gradually lowers over time due to aging panels. CQSola solar power controllers allow panels to operate separately allows ages panels to only affect themselves, and not the entire string.
Our modelling has estimated up to 25% more power during the later years of solar farm production due to differences in aged panels. Enquire below to get a model designed for your farm, or future farm.
Reduce running costs by up to %504 with our patent pending technology
Employ Staff during the Day, Safely
Introducing the world first capability of turning off a solar farm. or a single string, whichever you need at the time. This allows your staff to switch whole strings to Zero Volts1, safe to work on during the day.
No more panel grading
No more man-power needed for sorting panels. Each panel operates separately of one another, and can be put in individually. The maximum power will be preserved. If a single panel fails, you don't lose all power from the string; just the one panel
Clean Panels only when they're dirty
With one-second, individual panel data; you'll know when each panel is dirty, and only start cleaning when a panel is showing signs of performance loss, saving you man-hours and call out costs.
Reduce your inverter costs4
Without a central MPPT, the central solar farm inverter can be replaced with any Constant DC input voltage type inverter. Reducing costs significantly
Claim Warranty on broken panels
With full visible data, broken panels are quickly and easily identified, and without extra testing; can be sent back to the manufacturer within the warranty period for a replacement panel
Use second hand panels
With each panel operating separately, any panels can be used; Even second hand panels from other solar farms.
Reduce build costs; Design with overhead cables
You can read that again. With these solar power controllers active, only the single panel is affected by the shading over overhead cabling.
Allowing you to cut cabling cost substantially, and retain your output
Engineered to be tough and compatible
IP68 Water Resistant6, and suitable for at-sea solar farms
Each power controller is completely sealed, and rated to IP68. Without any metal outside of the box, the devices can be submerged in salt water for an hour without consequence, making them ideal for at-sea solar farms
Designed for SIL2 Safety Certification6
SIL2 Safety certification requires 2 independent systems within the controller to continually detect the device is operating safety for it to be flagged as safe for operation. If any one system fails, the device automatically goes into shutdown.
Our controllers run between 99.2% - 99.5% efficiency, with almost no heat loss, our controllers can run silent without a fan in sight.
On Device Data collection
We store all data on the communications units, and sync to the cloud when internet becomes available. Even with an unreliable internet connection, all the data is preserved, and pushed to the cloud when internet is available.
Compatible with all Batteries and Inverters
Now and in the future. The output of the CQSola solar power controllers acts like panels on the system. If the Battery or inverter can receive power from a panel, the controllers will work too.
Between -20°C and 70°C Degrees operating range3
For solar farms in irregular climates, our controllers will run in a wide range of conditions, from moisture heavy, hot conditions to light snow conditions.
