Re [Green-India] Re: SunCube achieves certification

[chan...@sancharnet.in]

Hi All.
I have been a silent observer on SunCube issue for some time.
Let us put the issue straight. What we want out of a system? Power output as per claims.

SunCube is a modular scalable unit. One piece as it looks in the photograph is pretty small (Seems less than 2 sqm, Mr. Kelkar may confirm the exact size). It is very possible to install such one unit at many locations and record practical output with reference to the radiation at that location. If any performance curve is available for the SunCube (Power output Vs Global Solar Radiation) varification is easy.

I request Mr. Kelkar to share the performance curve of one unit and the cost at which he wants to offer. I understand the factory in Satara is already manufacturing the units, so it must be possible to sell few units to prospective clients like us. We have all instrumentation like solar sensors, data loggers, D.C. energy meter etc. required to record performance of the unit. We can purchase one and record the output data for our interest as well as for the interest of others. If there are any calculations available for prospective investors in the project, please share with us.
Regards,

Prof. Ajay Chandak.

Hi Greg,

You seem to be under the impression that I am against the SunCube and
Square Engineering when in fact I am not. Nothing would give me
greater pleasure than to see a Made-in-India SunCube be available with
full government and utility support throughout the world. I have
conveyed this message personally to Shri Kelkar, I now convey it to
everyone.

Although I haven't claimed the CB is superior to a certificate of
conformity for archiving of technical file, I might venture that if
the process of getting UL, DV, LCIE and PV Quality Mark is smoother
with a CB certificate (15 days?) than without (???), then a CB
certificate might have its merits.

Ultimately, which certification process Square Engineering goes in for
is entirely their call, since I have no stake in their business or
yours. As a well-wisher and proud Indian, I might only suggest that
other systems (such as CB certification) might make the path towards
worldwide acceptance smoother for SunCube and Square Engineering.

You may agree. If you don't, what ICE, ESYD, BIS, bloggers, well-
wishers, etc have to say is irrelevant. Investors and customers would
beat a path to your door when you ultimately have the official
government and utility subsidy and support.

All the best,
Shrikanth

GGE recently published "12 months of measured SunCube AC kWh generation." The data is available here. Further, SunCube aperture is 1 Sq.m and it needs to spaced about 2m apart. Detailed specs are available on GGE and Square Engineering website.

Thanks,

Hi Prof. Chandak,

We have recently published 12 months of AC kWhs production as against the
Nasa DNI for our rooftop test site with +- error bands. We also have
measured the SunCube's average DC conversion efficiency at 31% with 40% STC
and 1,000 Sun Emcore cells. By then taking the Nasa DNI data and the DC
conversion efficiency we can predict what the SunCube should produce at a
given lat and lon. Note the Nasa data is averaged over 22 years and average
over an area of 1 deg NS by 1 deg EW so localized conditions which may
effect the DNI availability may cause lower outputs.

Hi All,

Within a period of 3-4 weeks maximum our plant in Satara will go online if all the equipments required for putting the plant showing video of the plant and outputs from the inverters are received as planned.

Doing this anyone who clicks the link will have a real time video and inverter log in details.   This will also have solar input data and data logger.  I hope none of the PV people would have done this.  Important is CPV being new player in the field will have to go naked to prove the metal  !!!

This is what I hope will answer all the questions.  Must complete this job to answer UL, IEECE CB etc  notions and show to the world that YES THE CUBE DELIVERS FROM WHAT EVER IT GETS FROM SUN, EFFICIENTLY.

Regards

Deepak Kelkar
