NTT Energy and Environment Systems Laboratories developed a circuit module that enables the charge of a lead storage battery with a single photovoltaic cell . The circuit module consists of a boost circuit with a DC-DC converter and an IC equipped with the "MPPT (maximum power point tracking)" function. The boost circuit can increase the typical voltage of a single photovoltaic cell, about 0.5V, up to 15V.

Peter Russo and Brendan Wypich of Stanford University developed the SmartSwitch , a light control with tactile feedback that helps you "see" how much energy is already being used, whenever you try to flick the switch. If the total energy consumption in the house is low, the SmartSwitch is easy to flip. But if the consumption is higher, the SmartSwitch is physically harder to flip, thanks to a brake pad within the mechanism. The idea is that people will use this tactile feedback to decide if they really really need that light on or not.

PG&E Strengthens Leadership Role with Announcement of Significant New Solar Program
NRG Energy, one of the United States' most coal-dependent utilities, on Monday signed a deal with California startup eSolar to develop solar power plants. The agreement calls for NRG to invest $10 million in Pasadena-based eSolar for the right to use the startup's technology to develop and operate three solar power projects in California and the Southwest that would generate 500 megawatts of greenhouse gas-free electricity. NRG ranks as one of the nation's dirtiest utilities, spewing 70 million tons of carbon dioxide annually from its coal-fired power plants. eSolar will use fields of mirrors to heat water to create steam that drives electricity-generating turbines.

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.
