HOW TO UNDERSTAND ELECTRIC CAR FUEL EFFICIENCY and FUEL CONSUMPTION (or, what the heck is MPGe).

How do we determine the fuel costs of an electric vehicle? How do we really know the cost comparison to drive an electric vehicle 100 miles, vs. driving a gasoline vehicle 100 miles? What does MPGe mean? Get the answer to these questions and more.

PVinsights:Cooling global demand undermines solar prices

Both multi-crystalline and mono-crystalline modules extend the price slump this week amid the lingering weakness in global demand. In particular, the demand in China observes an obvious weakness, which results in inventory increasing for Chinese module makers. Hence, the solar panel price in China sees the continuous drop as Chinese module makers are trying to reduce the inventory level through the strategy of the price reduction. In Japan and India, due to slower demand, the escalating price competition from Chinese players drives the solar panel prices down.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
