A passive solar tracker maximises power yield from your solar array by up to 42% in Australia.
A fixed solar array only produces maximum power when the sun is directly overhead. The sun moves constantly so fixed arrays only produce maximum output for about an hour a day. For the rest of the day the array is operating at a significantly reduced output.
Solar tracking arrays achieve maximum power yield by ensuring the modules face the sun for every available hour during the day.
SolarTrack uses a simple passive tracking system. Natural warmth from the sun and gravity provide all the energy required. Fluid movement from one side of the tracker to the other keeps your modules aligned towards the sun. The Self Reorientating System (SRS) automatically repositions the array overnight ensuring the array is ready for peak performance at sunrise.
The simple passive design of SolarTrack overcomes many of the short comings prevalent in electronic trackers. Powered trackers suffer from operational failures due to high wind loadings exceeding motor and gear/actuators ratings, electronic failures and flat batteries. Powered trackers use between 1% & 4% of the power generated by the solar array to perform tracking.
A simple design enables small, medium and large scale installations to be built almost anywhere. SolarTrack is cyclone rated making it a perfect addition to any solar solution in cyclone affected areas.
SolarTrack is made exclusively for and distributed by WA Solar Supplies.
Real Tracker Benefits
- Longer battery life: Reduces battery depth of discharge (DoD). Battery cycling is reduced because morning and afternoon peak loads can be powered directly from the solar array.
- Improve system efficiency: Net system efficiency is increased by bypassing the battery and powering loads directly.
- 42% more water: Your pump will start earlier and run longer so it will pump more water
- Lower system cost: Less PV modules and a smaller pump are required to pump the same amount of water per day than compared to a fixed array.
- Lower pipe line costs: Reducing the peak flow means a smaller pipe can be used and less money is wasted from pipe friction on long runs.
- Increase water yield from limited water sources: Pumping longer at a reduced rate will maximise the yield from limited water sources.
- Produce up to 42% more kWhrs of power than a static array.
- Smaller arrays required for the same power yield. Same power but less inverters, solar modules, cabling, installation time, civil works, etc.
- Maximise the grid connection and capacity. Grid capacity is allocated on peak performance and is often limited. Running at peak capacity for longer makes best use of this capacity and reduces the amortised cost of connection. All of which reduces your production cost per kWhrs.
- Land use not compromised in large-scale applications for many agricultural pursuits enabling dual income from the same land. The SolarTrack design enables the arrays to be separated to maximise yield by avoiding one array shading another early or late in the day. The open space between still receives sunlight so grass, crops or vegetables can still grow. Grazing or cropping can still take place within the solar field with only a small proportion of the land actually taken up by the trackers. You are also providing a windbreak to protect crops or stock and reduce erosion & soil moisture loss. Shade for small animals is also provided.
- Tracking often matches peak power in summer, offsetting the most expensive power costs.
