by Abid Jamal @ electronicslovers.com: what is Mppt( Maximum power point tracking) ? “we use MPPT algorithm to get the maximum available power from the Photovoltaic module under certain conditions” How MPPT works ? Why 150W solar panel does not equal to 150 w? For example you bought a new solar panel from the market which puts […]

R. Colin Johnson @ eetimes.com: PORTLAND, Ore.–Now before you get all excited by the headline, which is not click-bait according to the researchers, a new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity, plus be tuned to nearly any other frequency as a detector. The invention was made […]

by Graham Prophet @ edn-europe.com: Cypress Semiconductor has introduced what it believes to be the lowest-available-power PMICs that enable an integrated module size of 1 cm² for solar-powered wireless sensor node (WSN) designs. Intended to manage solar-powered wireless sensors for Internet of Things (IoT) applications, these parts are said to be the lowest-power, single-chip Energy Harvesting […]
