Roof – integrated Solar Flat Roof from IB Roofs

Building-integrated solar flat roofs are cool, green and have the lowest cost/watt to install, and virtually no maintenance cost. IB makes Lifetime residential flat roofing and now they together with Uni-solar have the only real BI-PV solar flat roof system for your home or business.
Find out more at http://www.CoolFlatRoof.com

Benefits of thin-film solar and Roof integrated IB Solar-Wise PV systems include better than average light capture in cloudy conditions, minimum roof penetrations, no shading from adjacent panels, and combined 30% federal tax credit for both the Solar and the roofing system.

I am looking to purchase Solar PV panels as cheaply as possible in the UK. In particular damaged solar cells are of interest for my hobbies www.homebrewpower.co.uk

Does anyone know of any good sources within the UK?

Price range of around £1.00 per watt MAX

Try ebay..

Ever wonder what happens when solar panels are covered in snow?

I want to start a business making pv solar panels.

That’s kind of like starting your own automobile manufacturing business. To be profitable, you would unfortunately need a large amount of starting capital. If you look around, there aren’t a lot of little companies making pv panels. The ones that are profitable are huge and control the supply chain starting from raw materials. And even those might be taking losses next quarter. Sorry, just trying to be realistic.

Nowadays, many building featured some PV panels in their roof, wall, etc. Is there any short/fast method to calculate how many panels we need? And is it need a battery room to restore the power?

A battery doesn’t "restore" power, whatever that means, it stores it for times when there is no sun.

The incident energy from the sun is about 1000 watts per square meter at high noon. A solar array at 10-15% efficiency will generate about 100-150 watts per square meter.

.

not the water ones the electricity, its for auni project im using a energy asssesment programme and i have potential 10m2 of solar panels. however theprogramme asks for the Kwp?

The supplier should tell you.

kWp =
Area * efficiency of the panel AS A FRACTION (so 15% efficient = 0.15)

This is pretty simple because efficiency is calculated for a spectrum of light with 1kW per metre squared intensity. The real equation is kWp = Area in m^2 * assumed intensity of 1 kW m^-2 * efficiency.

You could also calculate it if you know the maximum current out and voltage from P=IV.

If you can’t find any info for your panels, you can try looking at panels on the internet and seeing what they give you in kWp/m^2.

Crystalline comes in an ingot, which you must saw into wafers. Or else you must buy wafers, paying someone else to saw it. That costs more.

Amorphous can be deposited as a film, cheaper to make. And as you know, it’s not as efficient or durable as crystalline.

I have space that i feel would be great for this but is very dirty and greasy. In the Process of cleaning it up.

You need a "cleanroom" to begin building PV solar panels. Although the equipment needed to build solar panels is not expensive by industry standards (10s of millions vs. a few billion for the state of the art microprocessors.

There is a balance and trade-off between how clean and the quality of the PV being produced. But generally I would expect that you would need a system to remove all particles greater than 200uM (Class 200). You need to keep particles out and this is accomplished by having positive air pressure so that the air pressure in the production area is higher than the local atmospheric pressure. Also temperature should be controlled +/- one or two degrees, and humidity to a within a couple of present.

At this point you would have to calculate what the conversion cost would be compared to building a green-field building.

SunTech introduced their Reliathon 270-watt module at this year’s Solar Power International. Wei-Tai, VP of Marketing for SunTech, spoke with the Buildaroo News Team about this products unique characteristics. Watch the video above to see the modules as well as a demonstration of SunTech’s innovative mounting system. Some unique characteristics include:

self-aligning panels, integrated grounding, and wire management, as well as a new “Two-in-One” design, with two 36-cell regions featuring independent circuits that can create better output on fixed tilt systems in early morning and late afternoon. All module innovations result in far less labor time needed to install Reliathon systems as well as significant reductions in material costs.
Array Technologies’ DuraTrack(TM) system was designed specifically for Suntech Reliathon, and makes use of two motors per MW AC versus the typical four motors per MW, further reducing the material costs of the system.
The new Suntech Reliathon ground mount system perfectly matches Reliathon modules to deliver fixed tilt solutions at lower cost and greater profitability.
Utility-grade Reliathon module warranty: The Reliathon module includes a 25-year utility-grade warranty offering an industry-leading 12-year limited product warranty (extended from 5 years) and a 25-year peak power performance warranty now based on annual degradation instead of 12 and 25-year step-downs. The new annual peak power performance warranty provides Reliathon module buyers with 13.8% more warranted power over 25 years. Overall, the new terms warrant an industry-leading 85% power output level at 25 years.
Preferential pricing from industry-leading partners: Power plant customers purchasing a Reliathon system will have access to customized Reliathon partner products at preferred pricing and pre-negotiated business terms offered by Advanced Energy, Array Technologies, Satcon, Siemens Industry and SMA, providing greater value over whole system purchase.
Reliathon modules and system components will be available in the United States for immediate orders with shipment scheduled in Q2 2010, and have already been included in over 1GW of US solar project bids.
