So I just had a look at the ikea.co.uk website and they are selling in partnership with another company Hanergy, "Ikea family" members get a 15% discount. I clicked through to their online calculator and the results it gave were utter rubbish. It reckoned that a south facing 3.84kWp array at 45deg pitch in central Edinburgh would produce over 7000kWhrs a year. PVGIS reckons on 3400kWhrs which is much more believable.

It would be interesting if others tried this also for their actual locations to see if it was just a single bad result or a calculated attempt to suck people in.

N.B. The online calculator won't let you see the result until you input Name, telephone and email address. I just used nonsense values for all, Fred Bloggs will be getting a lot of sales calls later today!

Maybe the family card doubles your output?!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12628&Focus=210358#Comment_210358 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12628&Focus=210358#Comment_210358 Sat, 04 Oct 2014 06:24:36 +0100 Chris P Bacon
It has only been throwing up rogue results for Edinburgh for whatever reason.

Testing in 4 or 5 other locations around the UK I got estimated yearly outputs of between 3400 and 3700kWhrs from a 3,84kWp array but choosing another different address in Edinburgh again gave a prediction of 7100kWhrs/a from a 3.84kWp array.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12628&Focus=210367#Comment_210367 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12628&Focus=210367#Comment_210367 Sat, 04 Oct 2014 10:02:39 +0100 jamesingram no wonder houses are so pricey]]>
