Keep the controller and junction box sealed
Unused holes must be sealed against animals, insects,
water and dirt. Each hole is supplied with a rubber plug that can be kept in place for this purpose.
CAUTION Loose connections are the most common cause of system failures.
Pull on each connection to confirm that it is secure.

Illustrated on the next pages is a 300-watt solar-direct system with a pole mount. The pump controller
and the junction box are installed on the pole. The array is set at summer tilt angle. The controller is
mounted on the north side of the pole, directly under the array. This shades it from the hot mid-day sun.
This system was installed by students in a solar water pumping class.
