Download Free Android App For REnergy!!

This is a free android app for this blog : REnergy. I've built this app for the users of my blog to access my posts, works with ease. The best thing of this app that you can now view, comment, share and everything else just by some taps with your android smart phone. I'm trying to add an option to login and post an article directly via this app from the user's smart phone. You still can download it and install in your android smart phone for easy...

REJUVENILE INVENTION BY MIT

MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide, and take square roots, using three or fewer genetic parts. Inspired by how analogue electronic circuits function, the researchers created synthetic computation circuits by combining existing genetic “parts,” or engineered genes, in novel ways. The circuits perform those calculations in an analog fashion by exploiting natural biochemical functions...

JU prof nominated for Becquerel Prize!!!

Courtesy: Times of IndiaA teacher of the electronics engineering department in Jadavpur University — has been nominated for the 2013 Edmond Becquerel Prize.     Colleagues of Ghosh consider the nomination as a huge achievement in itself, given the rarity of the award been conferred to scientists beyond Europe. Japan’s Masafumi Yamaguchi is the only recipient of the award from Asia.     World Council for...

Commonly Used Algorithms for MPPT

The amount of electrical power generated by a photovoltaic system depends on solar irradiance (solar energy per unit area of the solar panel’s surface) and other conditions such as temperature and cloud cover. The current and voltage at which a solar module generates the maximum power is known as the maximum power point. The location of the maximum power point is not known in advance.Solar inverters or charge controllers use maximum power point tracking...

Maximum Power Point Tracking : Basic Overview

Solar inverters or charge controllers use maximum power point tracking (MPPT) to get the maximum possible power from the PV array. Solar cells have a complex relationship between solar irradiation, temperature and total resistance that produces a non-linear output efficiency known as the I-V curve. It is the purpose of the MPPT system to sample the output of the cells and determine a resistance (load) to obtain maximum power f or any given environmental...

Solar Tracker : Advantage and Disadvantage

Solar tracker is a component/tool/plugin in solar PV system which let the solar panels/arrays facing the sunlight directly or you can say at 90 degree angle respect to the sun-light. In other words-"A solar tracker is a device that orients a payload toward the sun. Payloads can be photovoltaic panels, reflectors, lenses or other optical devices."In flat-panel photovoltaic (PV) applications, trackers are used to minimize the angle of incidence between...

MPPT based (Perturb & Observe) Solar Charge controller:: Paper Work

Maximum power point tracking (MPPT) based solar charger/charge controller plays a vital role in increasing the overall efficiency of solar PV based system. Implementing a MPPT algorithm in charge controller of a solar PV system is necessary because the current-voltage characteristics of solar PV arrays is non-linear where at a particular point the power output is maximum. So to extract the maximum power from the solar PV system, implementation of...
