Modules
American Made POWERTEC® PLUS modules use a monocrystalline cell technology with a module efficiency of up to 15.27%. Tolerances of up to +5 watts guarantee maximum power without compromise. Nominal power is consistently obtained and exceeded. Modules are guaranteed to produce 90% of their nominal power for 12 years and 80% for 30 years. With a 10-year product warranty, POWERTEC® PLUS modules go far beyond competitors’ standards. Every module passes rigorous optical, mechanical, and electrical quality control and are certified according to the most stringent North American and international standards.

Inverters
All our inverters are designed to provide superior performance at a competitive price. Sunny Boy inverters are UL certified and feature excellent efficiency. Graduated power classes provide flexibility in system design. The SolarEdge inverter combines a sophisticated, digital control technology and a one stage, ultra-efficient power conversion architecture to achieve superior performance – over 97% efficiency and best-in-class reliability.

Monitors
The Sunny WebBox is a powerful communications tool that allows the performance data of your solar power system to be logged and easily transmitted via modem or Ethernet to the internet or directly to your PC. The SolarEdge Monitoring Combiner Box with GFDI allows you to enjoy a high level of system performance monitoring and exceptional system safety. The box detects string leakage and isolates the faulty string, ensuring other strings are not affected, and immediately provides on-site and web indication as well as email fault notification.

Mounting
With high-quality mounting and fastening systems for photo voltaic modules and solar thermal collectors you can create a solid foundation for any solar system on sloped roofs, flat roofs, open areas and façades. A wide range of flashing materials and mounting rails provide the flexibility to fit any need.

Flat Panel vs Evacuated Tube Solar Water Heaters

Guru — Tue, 09 Jun 2009 16:41:46 +0000

Although the evacuated tube solar water heaters are slightly more efficient in the winter and look cutting-edge modern, many people think the flat plate solar water heaters are esthetically more pleasing.

In fact, a 4 square meter flat plate solar water heater is equivalent in heat production to a 3 square meter evacuated tube solar water heater.

The flat plate solar water heaters tend to be a little less expensive, making them, dollar per dollar, about equal to the evacuated tube solar water heaters from an investment standpoint.

Quoting Intelligent Energy Solutions:

An independent study by the DTI compared a number of different types of system and the panel that produced the most hot water was of the flat plate variety.
