Good Day,

Do you provide any PV product in a CIGS configuration?
Can
you tell me, in your opinion, whether CIGS has an efficiency edge over
other PV processes or are there detrimental aspects to the CIGS products
that make them less desirable?
In your opinion, what is the very best, most economical and most efficient PV Product on the market today?
Just trying to do a little research and get some expert opinions.
Thank you so much for your time and any help you can offer.
Have a very good weekend.

I have prepared a R&D paper on improved and reliable solar power production. The paper is titled “ARTIFICIAL ILLUMINATION OF PV MODULES”. Solar energy is in its entry stage in India and there is very little scope for R&D. Is there anyone who can refer me with suitable opening so that I can take the next step in achieving my ambition.

Hi anderlan,

Here’s an excerpt from Elementary Energy re c-Si and CIGS ouput over a year in sunny Ireland:

A. There are a number of variables which can affect
this, but as a general guide; each kWp of Crystalline panels will
produce about 800 to 900 kWh per year in Ireland. Thin film CIGS panels
will provide a little more than this with about 850 to 1000 kWh per
year. We can calculate this more accurately following a site survey and
system selection.

I’ve heard that thin film is more able to convert low levels of sunlight (overcast days) than silicon. Might this allow, say, a film array to exceed yearly production versus a similar total Wp rated (but smaller given the greater full-light efficiency) Si array in a climate like Germany or Seattle?
