Solar Initiatives
Solar Pool Heating
Solar pool heaters work in partnership with your pool's filter pump to efficiently heat thousands of gallons of water in the pool.

Solar Water Heating
Integrated Collector System
A simple system that requires no pumps or controls for operation. It combines a water storage tank and the solar collector in one unit.
Solar Water Heating Thermosiphon System
These collect heat from the sun and transfer it to your water through a natural process, relying on the simple principle that hot water rises and cold water sinks.
Solar Water Heating
Active Direct System
Open loop active systems heat the water supply directly.
Solar Water Heating Active Closed System
These use a separate fluid that transfers heat to the water through a heat exchanger.

PhotovoltaicsA solar electric system consists of an array of solar electric panels, an inverter and a computerized solid-state controller. The solar electric panels generate DC electricity directly from sunlight. The inverter coverts the DC electricity produced by the panels to AC electricity. The computerized controller regulates the system and directs your extra power back to the utility grid.
Photovoltaics
Photovoltaic (PV) cells are made of special materials called semiconductors such as silicon, which is currently the most commonly used.
When light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor.
Photovoltaics
When the sun hits the cell, it excites electrons in the B area and they migrate to the A area. The electron flow provides the current, and the cell's electric field causes a voltage. With both current and voltage, we have power, which is the product of the two.
