International Wind Energy Development: World Market Update 2010

This year's World Market Updated includes a full chapter dedicated to Direct-Drive WTG versus Gearbox-Equipped WTG. The increased use of the direct-drive turbines across the wind market is impacting the wind industry. The World Market Update 2010 identifies and compares the pros and cons of both the direct-drive and gearbox-equipped concepts, as well as the implications of using permanent magnets on a large scale.

U.N.: Renewables could be 80 percent of energy by 2050

Renewable sources such as solar, wind and hydropower could fulfill almost 80 percent of the world's energy demand by 2050 with the right policies, according to a U.N. report which won backing from governments on Monday. The 26-page study, by the U.N.'s Intergovernmental Panel on Climate Change (IPCC), broadly matched a draft written by scientists. It was approved by government delegates at talks in Abu Dhabi. Environmental groups hailed the report as a guide to the shift from fossil fuels to combat climate change, a process set to cost trillions of dollars. But they said some draft findings were watered down, partly due to opposition by oil exporters. "Close to 80 percent of the world energy supply could be met by renewables by mid-century if backed by the right enabling public policies," the IPCC said. The report said moves to cleaner energies including geothermal or ocean energy would help cut greenhouse gas emissions, which it blamed for global warming including floods, droughts, heat waves and rising sea levels.

DEDICATED ELECTRICAL TEST KIT FOR SOLAR PV INSTALLATION

The new Seaward Solar Installation PV100 is the first dedicated multi-function electrical tester for those involved in solar panel installation. The new tester is capable of carrying out all electrical tests required by IEC 62446 on grid connected PV systems and eliminates the need for multiple test instruments for PV solar panel electrical installation and connection. With the push of a single button the new combination tester carries out the required sequence of electrical tests in a safe and controlled manner, avoiding the risk of contact with exposed live DC conductors.

IMO Precision Controls - Keeping Solar Safe

IMO Precision Controls - Keeping Solar Safe

The IMO FireRaptor provides three forms of Solar Panel Rapid Shutdown to ZERO VOLTS in case of fire or other emergency: Manual Panel Shutdown to 0V Operated from Ground Level, Automatic Panel Shutdown to 0V at >85°C (185°F) Temperature, and an automatic Panel Shutdown to 0V on External Power Loss. The FireRaptor can be installed without any set-up and with any string inverter as its functionality is completely independent. "Plug & Play" style installation using industry standard connectors is easy, whether fitted to new installs or retrofitted to existing projects to upgrade fire safety functionality. Meeting NEC2017's regulation to switch DC current at the PV panel in under 30 seconds, FireRaptor is remains one of the safest and most effective means of isolating DC current at the source, and the only rapid shutdown with a 20 year warranty.
