Photovoltaic thermal hybrid solar collector[edit]

Photovoltaic thermal hybrid solar collector should be added to this page - as an example in the first paragraph and as a 'see also' --Blobbybi (talk) 02:42, 19 March 2014 (UTC)

Maybe a small section that says something like:
Photovoltaic thermal hybrid solar collectors, sometimes known as hybrid PV/T systems or PVT, are systems that convert solar radiation into thermal and electrical energy and thus are solar thermal collectors that have photovoltaics. The main article is at: Photovoltaic thermal hybrid solar collector

External Link to updating calendar of Solar Energy events and expos on[edit]

I find the calendar of events on to be a useful resource for wiki users interested in Solar Energy. I have no affiliation with the site and this edit is not "link spam" as accused nor does it have commercial intent. The page is a simple calender of large international solar conferences and includes US and European events. ChristianJorn (talk) 00:52, 15 June 2014 (UTC)

It's a US site: I count one non-US event and six in the US (for which it doesn't even give the country, it assumes the reader is in the US). Apart from that it's a commercial site: their phone number is given twice (again with no country code) in large print, multiple links to 'find an installer' (which is also their front page), a link to their shop, and other adverts which alone take up more space than the small list of events. Finally you've been adding links to this site to multiple articles, articles you've shown no interest in before, which suggests you're not interested in them or improving them but just on promoting this site.--JohnBlackburnewordsdeeds 01:03, 15 June 2014 (UTC)

So what if most of the largest events are in the US, and so what if they have a phone number on the website? I don't know what "shop" you're talking about and there are several articles in wikipedia that are on nearly this exact same topic. I added no off-topic links to any articles, only to this calendar which I consider a good resource. You assume a lot. I did find the installer that installed my home pv system via this site and had a good experience. I also am interested in the solar industry and occasionally frequent these events. If you have a better source for an updating calender then please link to it, otherwise please revert this edit. ChristianJorn (talk) 01:14, 15 June 2014 (UTC)

The 'so what' is WP isn't a US-centric site, but a global one, with only a minority of readers in the US. Your own experience of it was as a commercial service, not an information resource – it's a commercial site. A better source for solar events? I I wanted to find one I'd use Google, which usually returns up to date results ranked by relevance, including geographic relevance. WP is not a 'directory of everything'. There is though one which I've added, DMOZ; you might add your link to that site which as a collection of links is a far better place for it.--JohnBlackburnewordsdeeds 01:51, 15 June 2014 (UTC)

DMOZ is not a calendar, and I like the site and the calendar. I can't agree with you that US and European Wikipedia users should be deprived of a useful resource just because it's on a site that provides some utility for people that have an interest in installing solar systems. If Google provided a calendar of solar events I'd link to it, but they don't. ChristianJorn (talk) 02:03, 15 June 2014 (UTC)

I like it is not a reason for keeping something in Wikipedia. The relevant guideline is our one on external links, in particular WP:ELNO 5 and 7. But I'll not remove it straight away. Perhaps another editor could look at it and see if it belongs.--JohnBlackburnewordsdeeds 02:54, 15 June 2014 (UTC)
I have re-removed the link. There needs to be consensus for the link before restoring. The site is spammy, and the material in the events directory is of questionable encyclopedic value. The link appears to fail inclusion material of both WP:ELYES and WP:ELMAYBE. Additionally, Wikipedia is not an internet directory; just because a link exists is not a reason to add it. There needs to be consensus that addition the link benefits the encyclopedic understanding of the article subject. --- Barek (talkcontribs) - 21:29, 17 June 2014 (UTC)

I strongly disagree. The link does not fail either of the first two clauses of WP:ELYES and the linked page contains neutral and accurate material that cannot be integrated into the Wikipedia article due to the amount of detail and that fact that it updates. To me, it isn't a stretch that readers of this article would consider the modern technology, understandings and information provided at these events to be relevant to an encyclopedic understanding of the subject. It is a clear Yes as I see it. ChristianJorn (talk) 21:58, 17 June 2014 (UTC)

Knowing the dates and times of events is most certainly not going to expand an understanding of the subject. At best its advertising for external events. --- Barek (talkcontribs) - 22:40, 17 June 2014 (UTC)

solar shadow less structures[edit]

                                                   solar shadow less structures

Reducing your cost of investment in solar with more returns......

now my panel efficiency highest 17.5 percent when current panel kept to south.

and have designed with no steal for plant which reduces 70 lakhs cost per megawatt and reduces land cost of 20 lakhs if 1 Acer cost is 5 lakh so totally reduces 80 lakhs to 90 lakhs per megawatt

if total project is 7.8 crores

it reduces to 6.9 crores....a new way in solar......


A shadow less structures implemented in solar. Design is used in individual structures and panels with shadow less structures and panels with rotating structure design

1.these designs increases efficiency

2. requires lesser area for installation hence increasing the land utilization

3.minimizing area consumption 2:1 ratio.

3. There will be no shadow, so the there will be better focusing and absorption of light resulting in increased energy generation.


[0002] Presently, solar panels are placed one after the other intervening space to

            prevent the shadow from falling on the panels thus requiring a lot of area for the
            placement of solar panels.

[0003] Conventionally, most of solar plants are designed with a provision to tilt them to a particular angle based on the direction of the sun there by requiring a lot of space specifically for solar energy generation. With the shadow less solar panel design. There is no need to rotate the panels hence all the panels can be placed side by side and can be placed horizontally. It can double as a roof and hence an efficient design.

[0004] Further conventionally, panels placed on roof came into existence, with shadow less structures we can place present structure panels to the shadow less structure, and efficiency for this structure will be more and reusing of land is done after installation. Rotating structure can also be developed with shadow less structure, top position will rotate towards the sun without producing shadow can be used for special designs in construction purpose.

[0005]In order to address the issue of an efficient model which occupies less space and is more efficient, we propose the current shadow less non rotating model of solar panels.  — Preceding unsigned comment added by Gali saivikram (talkcontribs) 16:43, 11 October 2014 (UTC)

Hi, I would like to edit a dead link on the NOTES section (No.43) with a new , quality, well based resource. The dead link doesn't provide any value to the reader, nor to wikipedia. the url of the new resource is Thanks Teddymamo (talk) 06:06, 9 January 2015 (UTC)

Footnote 18 is incomplete: Please change " Smil (2006), p. 12" to "Smil, Vaclav (2006) Energy at the Crossroads. Retrieved on 3 June 2012., p. 12" Page number "12" is correct! The document is available via the following pdf-link:

Sorry but I have no rights to edit the article myself. Thanks!

The Smil (2006) is a rather cumbersome reference note to the actual reference which is listed below in the alphabetical reference section as Smil, Vaclav (2006-05-17). Energy at the Crossroads... with a link to the PDF. So it is there, although the month/day bit is rather unneeded. Vsmith (talk) 16:37, 4 March 2015 (UTC)
