Many owners don't equip their solar arrays with trackers even though tracking the sun will greatly increase the power output. If you want the most power from your PV (photovoltaic) array, then you want the sun to remain at high noon all day. This simple, reliable tracker keeps the PV array precisely fixed on the sun at all times, just as though it were high noon. The result: 40% more power than from a comparable fixed array, an investment that quickly pays for itself. Experience has proven that passive trackers (which typically use the expansion of potentially harmful freon gas to cause the collector to move), have serious limitations: they do not reset quickly enough to fix the panels on the early morning sun, they are often overpowered by the wind and they do not work well at low temperatures. Hence, their pointing accuracy is not precise and (because they are single axis) they require seasonal adjustments to maximize power output. Wattsun trackers use an electronic control mechanism and contain no freon or other harmful chemicals and with the "Dual-azimuth" feature, Wattsun trackers do not require seasonal adjustment to maintain peak output from the array. The Wattsun Solar Tracker is effective in all weather conditions. Its revolutionary solid-state sensor finds the maximum sun available even under overcast skies, from sunup to sundown. Using dependable motor-driven actuators it keeps the PV array pointed accurately at the sun at all times. For a Wattsun tracked array, it's high noon every hour, all day! It makes sense to equip every array with a Wattsun tracker. It will pay for itself in a short period of time, and its simplicity and durability will provide long-term, low-maintenance performance with thousands of extra watts during the lifetime of the array. Wattsun Trackers maximize power production without the shortcoming characteristics of freon trackers.
