Solar Controls for PhotoVoltaic Systems
Dependable Power for Solar Domestic Hot Water Systems
» MODEL # PV-10
» MODEL # PV-M20
Siemens Solar has engineered the ThermoLine series of modules to power circulation pumps in pressurized indirect or closed-loop solar hot water systems.
Tests have show that systems using solar power can be superior to both AC systems with differential controllers and horizontal thermosiphon systems. PV-10 modules are designed specifically to match the physical and electrical requirements of AET collectors, making systems more economical, efficient and easier to install.
Solar hot water systems require a power source that can fully utilize available collector heat. To accomplish thie ARCO Solar has designed ThermoLine modules to economically match the power requirements of specific DC circulation pumps.
The modules begin operating the circulation pump when the insolation is sufficient to begin heating the water. As the insolation increases, so does the pump flow rate.
Maximum system performance is obtained by a proper component match. In most cases a properly configured system with ARCO Solar ThermoLine modules can outperform systems using an AC pump with differential control. |

MODEL # PV-10
PV-10 modules are dependable and they feature anodized black framing. A unique flanged mounting system on some models makes installation directly on the collector quick, easy, and visually appealing.
At the heart of PV-10 modules are high efficiency crystal cells. All modules feature double construction designed to meet the rigors of practically any environmental condition. |
