AllEarth Renewables (www.allearthrenewables.com) released its AllSun dual-axis tracker last spring. AllEarth offers complete packaged systems, which include PV modules, an inverter, the tracker, and a remote system monitoring (all shippable on a single pallet). Consumers can choose from 20-module (4,200 W) or 24-module (5,520 watts) model. Each packaged system is covered by a 10-year limited warranty, in addition to the 25-year PV module performance warranty. Note: PV modules can be sourced separately. The AllSun tracker utilizes GPS technology for active tracking, thus it can track the sun even during cloudy weather (so that it is aimed in the correct position for when the sun eventually emerges). The tracker is designed to automatically shed snow and to stow itself during high winds. The remote system monitoring provides users with daily, monthly, and yearly energy (kWh) production values via the AllEarth energy production webpage. The increase in system production for tracking systems (as compared to fixed arrays) can be up to about 45%, but as always, to get the full benefit of a tracking array, dawn to dusk solar access is required.
