As water temperatures warm from winter to summer, the demand for greater circulation and oxygen in the water increases. Using the sun’s fuel, air output from PondHawk increases as the days grow longer, aligning with the increased seasonal needs.
As the seasons shift back from summer into fall and winter, PondHawk adjusts to the lower seasonal circulation and oxygen needs of the pond.
Using the U.S. Department of Energy’s National Renewable Energy Laboratory’s (NREL) solar radiation conditions for your location, we forecast the PondHawk production profile at each proposed site. The assessment evaluates location options to maximize the PondHawk performance.
In the assessment chart above, PondHawk has unencumbered access to the clear sky. During summer months when pond temperatures are highest and the need for circulation is greatest, the volume of air generated by PondHawk increases, since longer days yield more daylight hours.
PondHawk works year-round, and the increased summer season performance will reduce or eliminate your algae mitigation costs, helps maintain pond capacity and defer the expense of future dredging. Solar-powered PondHawk is grid independent, incurs no electric bill and is easy to maintain.
In this example we illustrate the annual yield of three locations.
The three dots indicate three potential PondHawk® locations. The performance curves show the impact of trees on the monthly volume in cubic feet of air that PondHawk will deliver at each location. The yellow dot location corresponds to the yellow performance curve in the graph, the green dot with the green line and the blue dot with the blue line.
As you can see, simply locating PondHawk away from the trees (blue dot and line) dramatically increases the April-through-May performance.
The SunSeeker site assessment tool is widely used by golf course superintendents for tree management. The app determines the best location for maximum sun exposure.
In the screen shot below, you can see the PondHawk location marked by the red pin. This location is almost completely shade free. However, there is a potential for shading at 12pm if the trees at the lower edge of the pond are very tall.
The SunSeeker was originally designed for companies who install solar panels. Indoors, the app can show aerial shade coverage on any given day or time. Outdoors, you can use the 3D feature and your device’s camera to get a real time look at the sun’s path.
