Wind-Solar Hybrid System

The DS300H Hybrid Turbine

The Hybrid system will incorporate a DS300W Turbine with a 250W PV Panel to power the LED light(s).

Peak operating times for both wind and solar fluctuate throughout the year and day. In response to providing twenty-four seven energy sustainably, our Hybrid systems incorporate the two, allowing for available energy to be utilised at every moment, overcoming the limitations of heavy cloud cover, nightfall and windless days.

Meeting your needs

By exploiting the available energy all day and night, our hybrid system can power lights, and or CCTV operations, motion sensors and charging points (grid support). 

These full hybrid renewable lighting systems combine green energy storage and even branded signage for an off-grid lighting solution that helps companies reduce their carbon footprint while saving on energy costs.

The result is a highly reliable off-grid lighting option for parking lots, walkways, business parks, and public areas, with the added benefit of custom signage and dimming solutions.

Key Benefits of the Hybrid System

  • Zero running costs
  • On or Off-grid
  • Efficient LED lighting – last 30x longer
  • Completely self sufficient (off-grid) - continues to operate even during power cut
  • No power bills
  • No trenching or underground cabling (off-grid)
  • Components easily removed
  • Instalments and relocation easily done (off-grid)
  • Permanent Magnet generator can be run in gentle winds (No gears)
  • Excellent durability
  • Combination of Savonius-Darrieus turbines provides an easy start up (3m/s) and high efficiency in low wind conditions.
  • Signage or bespoke designs can be added to further increase the structures appeal and value
  • Built in auto shut down of turbine when winds reach 34 mph or above to avoid damage to working parts.
  • Components easily accessible
  • No greenhouse gas emissions.
  • Interesting structure that draws interest, and demonstrates a commitment to seeking renewable alternatives
