Maryam Nosratinia; Ali Asghar Tofigh; Mehrdad Adl

Volume 2, Issue 1 , Winter 2015, Pages 1-5

http://dx.doi.org/10.30501/jree.2015.70059

Abstract
  The use of renewable energy sources is often suggested to be a good solution for climate change and the dependency to fossil fuel. Biogas utilization is a one of these promising options that can mitigate these problems since biogas is produced by the fermentation of waste, so is rich in methane and has ...  Read More

4. An Intelligent PV Panel Structure to Extract the Maximum Power in Mismatch Irradiance

Abdolreza Esmaeli

Volume 2, Issue 1 , Winter 2015, Pages 25-31

http://dx.doi.org/10.30501/jree.2015.70061

Abstract
  a new intelligent photovoltaic (PV) panel structure to extract the maximum power in mismatch irradiance is proposed. In conventional structures, difference of irradiance between series panels can cause the deviation of maximum power point. In this condition tracking MPP becomes difficult and reduces ...  Read More

Olatunda Ajani Oyelaran

Volume 2, Issue 1 , Winter 2015, Pages 32-35

http://dx.doi.org/10.30501/jree.2015.70062

Abstract
  The effect of storage time on some properties of groundnut shell briquette with 5, 10, 15 and 20% binder (cassava gel) was studied. The briquettes were prepared using a motorized briquetting machine. The moisture content, durability rating, water penetration, calorific value and the ash content were ...  Read More
