Solar Energy Conversion Process: Light and Heat

Photon Enhanced Thermionic Emission or PETE, simultaneously combines the heat and light from solar radiation to create electricity. Traditional solar panels utilize photovoltaic technology, which is flawed in that it decreases in efficiency as temperature rises. This is an obvious problem, seeing as the sun produces both light and heat. The new process of PETE, actually increases efficiency of the panels as the heat index increases.

Sanyo Canopies Create New Solar Vernacular For Architects, Building Owners & Hoteliers

Design Flexibility and Superior Energy Output of SANYO's Bi-facial HIT® Double Modules Provide Architects & Building Owners More Solar Design Options and Increased Revenue Potential

Low-cost and high performance heliostats

Heliostats are the component with the greatest impact on the cost in solar tower CSP installations, assuming 50% of the total investment. In the last years, there have been serious attempts to reduce cost by relaxing some features. The TITAN TRACKER concept achieves the goal of reducing cost offering higher performance than the rest of heliostats.

Training in Solar System Installation

There are several options available for solar energy education ranging from 1 day introduction courses through 2 year degree programs. There are community college programs, trade schools, courses offered by not for profit organizations and associations, manufacture product training and e-learning or online courses.

Project Showcase - Montana's Biggest Grid-tie PV System

We asked some of the Dealer / Integrators in our company directory to send us examples of projects they have completed so we could share them. If you have one you'd like to submit please email news@altenergymag.com and we'll send you a template to use so we can publish it here.

Home Build Solar System

I wanted to build my own solar system and I can tell you now it's possible with materials bought local in DIY shops and easy to obtain parts from the Internet. No I'm not a technical wonder and I don't have lots of experience working with electricity, I just looked around and taught myself how solar panels are made, how other might have done it and made out of this a workable plan of how I could do it.

Case Study - Western Reserve Wind Project

The leadership of Western Reserve Local Schools should be applauded for installing a wind project that allows them to be fiscally responsible, climatically aware and educationally adaptive.

AltEnergyMag Interview -Thermal and Hybrid Solar Collectors

With the Volther Solar hybrid collector, production of both electricity and hot water is done simultaneously. In PV modules, as the module temperature increases, the efficiency of the module drops down. In hybrid modules, the module heat is absorbed in order to produce hot water. In this way, PV efficiency is optimized as the heat is transferred into water for hot water production.

Solar Federal Buildings Program

Why aren't more Federal Buildings covered with solar panels?

What Building Owners Need to Know Before Going Solar

If you are a building owner that is considering a solar panel installation, there are several questions you should ask before signing any contracts. What is the best mounting method for installation on my rooftop? Do I need a new warranty to protect myself from any damage? Which type of system will give me the best ROI? Do I work with my old roofing company or do I need to find a structural engineer?

The Solar Industry: Where it has been, where it is now and where it has to go

The average solar stock has moved up 124% since March 9th 2009 and the average gain for just the 8 Chinese based public solar companies ( CSIG,CSUN,JASO,LDK,SOLF,STP,TSL,YGE ) was an amazing 267.96% !

Power Optimization Approaches for Trouble-free Project Execution and Superior System Performance

As photovoltaic technology increasingly penetrates mainstream markets rooftop solar PV system integration based on series configured arrays are becoming antiquated due to new system design architectures enabled by new inverter technologies.

The Promise and Pitfalls of "Solar as a Service"

By offering a means to install a solar power system without the initial capital, Power Purchase Agreements could be the Holy Grail for mass market adoption of solar. After being a major driver of solar installations over the last couple years, however, a number of obstacles still stand in their way. What makes these instruments so attractive?

How Improvements in Thin-Film Silicon PV Will Keep it Alive in the Marketplace

Thin-film silicon uses about one-hundredth the amount of silicon used by crystalline silicon PV but now that the silicon shortage is over what will keep TF Si'c current 43% market share from dropping?
