Nanosolar: Solar Power at a Lower Cost

Posted in Future Technology | Photovoltaic Cells | Solar Power

Nanosolar: Solar Power In a market-friendly scenario, Nanosolar claims to be able to produce electricity at 5-6 cents/kilowatt hour almost as cheap as power from coal and at about one-third the cost of other solar power. Nanosolar claims: Nanosolar claims mass production of solar power will now become feasible with their differently manufactured solar panels. Conventional silicon-made solar panels have a stiff competitor from CIGS semiconductor printed solar panels – composed of copper, gallium, indium and selenium – which perform as good as conventional solar panels in lab conditions. An inexpensive printing process makes it ideal for mass production by an automated facility with robots and other hi-fi equipment.

Solar panels re-invented:

The low efficiency which haunted Nanosolar raising the cost of installation of solar-power arrays and which necessitated more solar panels has been addressed successfully by Nanosolar. The larger panels they are now using generate more power; with modifications that cut the cost, the larger panels generate 160 watts as against 70 watts by First Solar.

Power output:

According to Martin Roscheisen, Nanosolar’s CEO, in sunny locations, power plants with these panels could produce electricity at 5-6 cents per kilowatt hour. Mr. Roscheisen claimed even the 16.4 % energy conversion in sunlight as against 20% energy conversion in the lab and only 11% of that energy into electricity by Nanosolar is high enough compared to conventional solar panels.

Raring to go!

Based at Germany and enjoying a huge market thanks to government’s incentives for the solar cells made of CIGS semiconductor, Nanosolar is ready to storm the market with producing solar cells twice as fast as the conventional solar-panel factories. He is ready to give First Solar a run for its money.

Not bankable?

But the claimed low costs are attainable only at close-to-capacity operation level which is at best a distant possibility. Because despite all improvements, under the current economic scenario, Nanosolar is finding it tough to find banks willing to back power plants which may be ready to use their solar panels. Now the panels are not yet “bankable;” but Nanosolar is hoping for a better future.

    He should be showing us what he was showing his audience rather than himself.

  • David Williams

    Why don’t they try selling those panels to the public like they said they were going to do several yrs. ago and then decided to only sell to utilities with big dollar contracts!

  • Luke

    Agreed with Ed… The video got old fast, not seeing what he was talking about.

  • Ton

    Does the price include the other accessories? I also wonder if they have used any toxic chemicals during the process like PV

  • holley

    I feel like this technology will only get better, less expensive, and easier to implement. Pretty cool to see the evolution… and the Gulf oil spill is a great reminder that there is no better time than now.

  • styke

    If these were even close to the price we are told, then utilities would be buying like crazy. Instead, it is big news whenever a utility selects nanosolar, and most choose someone else.

    I don’t doubt it is a clever idea, and maybe one day will contribute to a decline in price for photovoltaics, but I do doubt that they are 20% better than anything else.

    Could this nanosolar do the layering of John Rogers and Xiuling Li Making of layered ultra slim gallium arsenide pancake design?

    If they only sell to power plants, they probably wont even lower power costs, if you give to the public, all the power plants money goes to the people instead of that bloated power profiting. I want cost and measurements listed on their site, INFO. Set a large minimum, but never shut out the public.

  • July Argirov

    In fact the technical characteristics of this PV panel sound as extremely efficient. Of course there is too many questions about at what solar radiation the panel’s power of 160 W (80 W/m2) is measured.

    I am trying form 3-4 days to communicated with Nanosolar people by e-mail (since my local time is about 11 hours before their but nobody respond).

  • Barbara

    If you would like to try this technology on a fairly new home in the Phoenix, AZ area I would gladly volunteer my residence as a trial home. Think of it as helping out a senior citizen. 😉

    I think they should check out Germanium instead.
