The Amish and Solar Power

Amish people reject societies electric utilities and grid but do allow themselves to make use of the sun’s rays. Referring to solar power as “God’s Grid” some Amish are selling solar panels. They use solar power to juice up the typical gadgets but also to charge up the batteries under their buggy’s.

This blurb from the Hartford Courant: “The Amish decide on whether to adapt to a new technology based on two implications: their separation from the world and the impact on the community,” said Kraybill, the professor.

To protect their community from the influence of the outside world, the Amish sometimes wait for a bishop council meeting before installing special solar equipment.”

Apparently they’re quite fearful about allowing technology into their lives and homes that would be a doorway to watering down their strict culture. Understandably, they don’t want their children being corrupted by modern society and they view this or any technology as a worldly threat.

Said one Amish man “”If we would introduce cars to our society, we would not have a community for very long. It would rip our family apart.”

The Amish and Solar Power

Solar Thermal + PV = Efficiency x 3

Efficiency

No sooner do I write about co-generation as a means of conserving energy and reducing emissions, then I find out that solar innovators are already applying such technology by combining solar thermal and photovoltaic systems. The difference? Instead of minimizing losses, co-generative solar systems are maximizing gains. In doing so, these innovators say, they can triple system efficiency.

A solar PV system will usually convert only 10-15% of sunlight directly into electricity for the home. The remaining 85% of solar radiation is lost as waste heat. Two companies, SolarWall and PVT Solar, are harnessing some of that otherwise wasted heat by adding solar thermal components to the electric system. The idea is simple. Solar panels are typically placed on roofs at an angle. Furthermore, there is typically air space left between the roof and the bottom (or back) of the panel. It is here that a significant amount of heat collects. This heat can be collected to heat water, space, even swimming pools.

This not only utilizes waste heat, but also helps keep the panels cool, allowing them to work more efficiently at peak hours. Also, adding solar thermal components does not necessarily require very much additional structure, subsequently adding a relatively small amount of cost to the co-generation system. Take solar water heating; a retrofit solar hot water system is the cheapest way to integrate solar into home energy plans. Combining that with a solar electric system makes it even more cost-effective. (more…)

Solyndra Reshapes the Commercial Solar Panel

Solyndra a Freemont California based solar product company has come up with what they claim is an improvement over the shape and performance of the typical flat solar panel. They have produced a photovoltaic panel that is more cylindrical in shape that according to them handles wind load and angle more effectively than a flat panel.

Solyndra constructs their panels of cylindrical modules that can capture sunlight across a 360-degree photovoltaic surface capable of converting direct, diffuse and reflected sunlight into electricity Traditional flat pvs require expensive mounting devices for installation and the flat surface of the panel is less effective at capturing sunlight as compared to the rounded modules that make up Solydra’s solar panel.

With convential flat panels the wind enters from the bottom of the panel forcing the panels to have to be strongly attached or mounted to the roof structure of any building. Solyndra’s panels are formed so that the wind actually flows through the gaps between the modules in the panel as you can see in the illustration. Their panels are also able to be fitted right next to each other snugly unlike conventional pvs, collecting the sun’s rays a little more effectively.

These solar panels can be installed without penetrating the actual roof structure unlike the typical solar panel. They handle the wind up to 130 mph so the attachment to a rooftop can be done with non-penetrating hardware and the whole installation can get done in the half the time. They say commercial installations will now take days instead of weeks.

The company produces these panels strictly for the commercial market here and Europe.

If you watch their video HERE you’ll see it’s basically plug ‘n play installation.

Scientists Go Public about Infrared Solar Energy

Solar panels, both conventional PV and even third-generation, organic solar cells, absorb visible and, in some cases, ultra-violet light. All of these technologies are limited by shading, rainy days, and nightfall. Basically, photovoltaics, both the old and the new, collect direct sunlight. But what, researchers are asking, about indirect light?

Indirect light reflects, in the form of heat, off of buildings during the day and at night. This infrared energy is not limited to solar energy either. Energy radiating from machines and electronic devices could also be collected and recycled into usable electricity. Sound pretty radical? Well it is, and some very complex science at that. Nonetheless, scientists are becoming confident enough in the feasibility of infrared solar technology that they are going public and getting excited about it. (more…)

Solar Cylinders?

Proving that there is no lack of creativity in the solar industry, Solaroad Group has come up with a radical space-saving design for solar panels. What they dub the ElectraWall is a cylinder-shaped solar cell that can be clipped onto any number of surfaces including walls, poles, or rooftops. Using, of course, cylindrical solar cells, ElectraWall panels have a variety of proposed benefits. These include no need for direct sunlight, easy installation, and built-in battery storage. They’re also made with a good proportion of recycled materials. (more…)

The Athenian School Shows Solar Smarts with Tioga Energy, REC Solar

The Athenian School in Danville will soon be using renewable electricity harvested from the sun to meet half of its annual energy needs. Today the School announced plans for a new 220-kilowatt (kW) photovoltaic project, which will be installed by REC Solar, Inc. and financed and operated by Tioga Energy. Comprised of 1,300 Mitsubishi Electric solar panels ground-mounted in a 30,000 square foot likeness of the School’s trademark “A,” the visually unique system is expected to be one of California’s largest non-profit solar energy projects upon completion.

Solar Q&A: How Many Solar Panels Do I Need?

solar panels

Of all the things you have to figure out when planning a solar power system, the number of panels you’ll need is a big one. Yet, all variables are interrelated and you can’t figure out how many panels you need unless you know some other important information first.

What is my daily power consumption?

You need to calculate how much power, in watts, you use on a daily basis. Your electric bill will be necessary for this. A lot of utilities actually break this down for you in your monthly statements. If you’re not so lucky, there are online tools to help you out.

How much sunlight do I get per day?

Another thing you’ll need to know is the average amount of peak sunlight you get per day. This means yearly average. So don’t think summer hours; many areas get great sun in the summer but you might not see it for what feels like a month in the winter. Be sure to calculate the average…and be conservative. There are online calculators to help you get this exact also.

Permasteelisa and Nextgeneration Solar Cells

Permasteelisa is a designer, producer and installer of “architectural envelopes” it states on it’s site. The type of company that surrounds buildings and installs office walls, furnishings, etc.. They are getting into nextgeneration solar panels through their participation in new technology that will allow producing solar panels without silicone.

The next 4 years will see the development of “organic” photovoltaic cells. They will also start-up an industrial production line of DSSC panels (Dye Sensitized Solar Cells). This innovative technology utilizes light-sensitive organic pigments and nanotechnology to generate electricity. These new organic cells will be more versatile and enable builders to integrate them vertically into the sides of tall skyscrapers. In addition to being less sensitive to the angle of solar radiation they are also transparent and may use different colors. All this makes for more pleasant visual solar cell integraton on the exterior of buildings.

The Universities of Rome Tor Vergata, Ferrara and Turin will be research partners in the project. The Australia company Dyesol will also be involved, through its subsidiary Dyesol Italia, leader in the sector for the supply of materials and technologies.

Making the visual aspect of solar cells/panels much more pleasing to the eye will do it’s part in overcoming the arguments of the anti-solar naysayers.
