Question by syrious: What is 100% efficiency in ref to solar power? How is it measured or determined?
I'm reading Sucatcher catches thermal energy at 31.25 % efficiency. So, if it could do it at 100%, how much energy would that be? Measured how? By what? Does anything pick up 100% and use it or make it useful?

Best answer:

Answer by Prof. Normal
A solar cell's efficiency is the percentage of incident light energy that is converted to electric energy. 31% is actually really good for a solar cell, most of them are under 20.
As for a theoretical 100% cell, the Second Law of Thermodynamics forbids any process from being perfectly efficient, but we'll keep getting closer and closer...

Question by J P: Quickest (and least expensive)way to heat an above ground pool on a cool day? Solar Fish, Black Solar Heating?
Above Ground Pool. I am having a get together this weekend. The temp is going to drop into the mid 60's. I hate to deal with the plastic solar covers (and I don't think they work all that well). I would consider a black tube solar heating system but don't know how effective they are. Are there any chemicals that will do it? What about the solar fish that leaks os Isopropyl Alcohol? I don't want to spend a ton...as I hope to get a heater next season

Best answer:

Answer by michael_54550
well, actually the best is to put the solar cover on and try to retain some of the heat in the pool...even if cloudy the rays of the sun still come thru and will generate some heat. But other choices are yours but they aren't going to help much, not like the cover will..

Answer by tipguy
It's the same as if the solar panel wasn't there. The energy turns into heat and light and is absorbed by the earth, oceans, and atmosphere.

Question by Pascha: How long do solar panels last, compared to the roof they are attached to?

Best answer:

Answer by Parsec Knight
Ive been using the same solar panels for 15 years, have move a few times so they last a lot longer than the roofs weve had over us. I am teaching my kids how to build wind generators, because we keep having power failiures when the wind blows. and recently its got very windy. I charge banks of battery's and keep my office running from dc-ac converters.

rhed Built by Poliform IDS 2012

Boat Front Side

Toronto, Canada (PRWEB) January 26, 2012

Toronto based multi-disciplinary design firm rhed announces their latest collaborative project with Italian home furnishing manufacturer, Poliform, to be unveiled at this year's Toronto Interior Design Show. The rhed built by Poliform project features the Boat House Pavilion showcasing a Co-generation Power Speed Boat. The project is the latest in a series of prototypes designed by rhed, manufactured by Poliform and launched at IDS, including Monk lounge [2010]and the Pod Villa at Templar-Lake on The Mountain [ winner of IDS 2011 best of show].

"The Boat House Pavilion and Co-Generation Power Speed Boat were inspired in two parts" says founder and Templar principal, Del Terrelonge. "Firstly, while visiting Poliform in Italy last year during Salone del Mobile, I was invited to spend some time by the sea and became inspired by a spectacular one-off Italian yacht. Secondly, it is an ode to the Canadian "cottage lifestyle”. The Boat House itself is a bit of a throwback to my beginnings as a graphic and packaging designer. The aluminum panels that enclose and serve as the skin or membrane, comprise the architectural structure of the boat house, which is scored and folded in the spirit of Origami.”

The house at IDS this year is a case study of glass panels, upon which the solar panels will be attached to power the boat house. The Glass version of the prototype will be installed in the proposed location in Prince Edward County, as part of the Templar Lake on the Mountain project. The speed boat, on the other hand, is rhed's small version of a mega yacht with its Stealth Bomber-like sleekness, yet with a power-generation system that is completely efficient and ecological. It too has solar panels on the back with glass enclosure of the engine block, which stores power in battery cells. The more the boat is in use, the more latent power it stores, and then co-generates back to the power grid, assisting and augmenting the solar powered boat house. Along with the installation, a video presentation of both the Boat House and the Boat, will be showcased during the show at IDS.

As rhed continues to develop, design, and build larger-scoped projects (i.e. The Templar Hotel, Templar Lake on the Mountain, the condominium projects Langston I & II and others), their focus is also on developing custom furnishings and products for specific uses. The rhed built by Poliform project was manufactured in Northern Italy, while facilitating all of rhed's designs into realization.

Joule Solar Energy and the University of Mississippi Make History while Teaching

Mississippi's Record Breaking Solar Roof Installation

New Orleans, LA (PRWEB) February 01, 2012

The University of Mississippi and Joule Energy, an integrator of high-efficiency solar systems, have announced the completion of a roof-mounted solar installation on the university’s Center for Manufacturing Excellence, to date, the largest solar roof installation in the state of Mississippi. The project was funded by a renewable energy grant awarded to the university by the Mississippi Development Authority, which was part of a larger pool of funds established through the American Recovery and Reinvestment Act of 2009, and subsequently allocated to the state.

While the project’s initial meetings focused on designing for maximum power output, it was soon determined that utilizing the opportunity to showcase and compare various solar technologies would better enable the university and its students to reap the most significant value from the work being done. The system is comprised of independent configurations of solar technologies and is comprehensively monitored to show real-time power production for each configuration, in addition to magnitudes for conditions most affecting the system’s output (ambient temperature, wind speed, and irradiance). The monitoring display is located within the building, and all production information can also be accessed online following the link: (http://datareadings.com/client/moduleSystem/Kiosk/site/bin/kiosk.cfm?k=RM7vdryt). Because of its special design, the system will serve as a highly-engaging, hands-on teaching tool for enabling the study of solar within the university’s curriculum, and for researching the technology’s viability and long-term benefits.

The system incorporates two brands of solar modules, each with unique operating wattages and efficiencies, as well as three inverter technologies, including a central inverter, micro-inverter array, and two hybrid string inverters with optimizers. Collectively rated for over 107 kW of DC Power, the system consists of three hundred and ninety-two (392) Siliken ART-245 watt modules and thirty-nine (39) Sunpower E19 320 watt modules. The solar arrays are mounted across three prominent university buildings and are inter-connected to the electrical grid for the supply of back-up power. Joule Energy is proud to have contributed to this landmark project, and looks forward to future opportunities to combine solar energy and education.
