August 13, 2011 Re-printed with permission Copyright, all rights reserved I recently got a copy of a utility bill for a Minnesota business that has a 40-kilowatt (kW) solar PV array. I wanted to learn how quickly he’d pay off his array with the electricity savings. I was shocked. Payback time was 30 years. ...
I recently ran a small, informal poll on a couple of solar (and related) online discussion groups, asking if respondents had installed solar on their own property, and if not, why not. Results showed, without a doubt, the two most frequent reasons people had not already implemented solar were: (1) the cost; and (2)...
Dramatic slowdown in Wisconsin’s renewable energy market activity anticipated What started out as an opening salvo from the Walker Administration to shackle large-scale wind projects has in six months turned into a systematic campaign to dismantle the state policies that support renewable energy development. Joining the executive and legislative branches...
Ups Renewable Energy Target: Between 35% and 40% by 2020 Raises Payments for Biomass, Geothermal, & Offshore Wind Applies Standard Degression to Wind on Land and Solar PV Despite widespread rumors in North America that Germany was abandoning its system of Advanced Renewable Tariffs, the country’s upper chamber of parliament, the Bundesrat, approved...
By David Dobs Electrical Engineer, PE Having been an electrical engineer with 35 years experience in the profession as a consulting engineer, I have always had the dream of someday owning a solar-powered home. In March 2011, I completed a course of study in the design and installation of solar energy systems and passed...
If you aren’t aware of it, urban centers use a lot of energy to heat and cool the buildings within their area. We’re talking millions of dollars worth of electric, natural gas, or coal energy each month. Traditionally, each building in an urban center, large or small, has its own heating and cooling plant....
We have been carrying out a Performance Research Project on Commercial Solar Hot Water for approximately four months. In that time, we have noticed some very interesting facts. Though not the direct goal of our research, we have noticed some very interesting bits of information, which from a ‘business standpoint’, we believe are the...
With so much of the interest focused on Solar Photovoltaics (PV, electricity generation), Solar Hot Water Technology has sat in the shadows for decades. At one time in this country, much of the hot water used for heating, cleaning, sanitation, and other uses came from solar heating, collectors mounted on rooftops of homes across...
We all know Solar Energy is in. We especially see it in the states, cities and provinces where there is keen foresight and knowledge. We all know Solar Energy is the most dependable energy source we have, and it’s free. We all know that our days on fossil-based and carbon-based fuels are coming to...
