3 INSTALLING THE SOLAR ARRAY
3.1 Location of the Solar Array
Sunlight is the “fuel” that drives a solar pump. Full solar exposure of the solar array is critical for the
performance of a solar-direct system.
Choose a location for the solar array that has unrestricted sun exposure through the day and through the
year. The array can be placed several hundred feet (100 m) or more from the wellhead. There will be no
loss of performance if the electrical wire is sized properly, but naturally, the cost of wire will increase
significantly.
WARNING A small shadow on the solar array will cause the pump to slow or stop completely.
Each PV module (panel) contains a series of solar cells (typically 36 or 72 cells). Every cell that is
shaded acts like a resistor, reducing the output of the entire array. Shading just one corner of the array
will reduce the power disproportionately, and may even stop the pump. Consider this when deciding
where to install the array.
To determine where shadows may be cast at any time of the year, you can survey the site with a
Solar
Pathfinder®.
This device is especially useful in forested areas or wherever there are obstructions nearby.
It is available directly from Solar Pathfinder (USA) Tel. & fax (931) 593-3552, www.solarpathfinder.com.
Place the bottom edge of the array at least 2 feet (.6 m) above ground to clear rain spatter, growing
vegetation and snow. Keep in mind that trees and perennial plants will grow taller over the years.
