To qualify for the guarantee of an export payment:
1) your system must be MCS certified, no DIY or non-MCS fitters
2) you must be exporting from a generation system IE not one with battery storage

Could see these deterring some uptake among GBF

Suppliers could voluntarily choose to pay you for exporting from your battery storage, but you've no guarantee they won't change their mind after you have paid to install the battery.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274317#Comment_274317 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274317#Comment_274317 Sat, 22 Jun 2019 12:26:03 +0100 djh https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274336#Comment_274336 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274336#Comment_274336 Mon, 24 Jun 2019 17:14:35 +0100 Doubting_Thomas
We have 2 SunAmp units which take PV diverted power as a priority, with any surplus then exported to grid. This has been working quite well in the last few weeks of very variable weather. Any shortfall on grey days is drawn down from the grid.

The SunAmp is technically heat storage rather than electricity storage, but by definition it bites a chunk out of the generated electricity that would otherwise be exported to the grid.

Then again, so does my fridge, which is a form of negative-heat storage too I suppose...]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274337#Comment_274337 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274337#Comment_274337 Mon, 24 Jun 2019 21:22:07 +0100 djh Posted By: Doubting_ThomasIt would be interesting to know how strict the definition of 'battery' is.

I'm not sure what your uncertainty is. The Smart Export Guarantee is all about guaranteeing payment for exports of electricity. A SunAmp doesn't do that, but it does reduce the exported electricity as you observe. So I think the effect is easily predictable.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274342#Comment_274342 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274342#Comment_274342 Tue, 25 Jun 2019 12:08:55 +0100 bhommels Some light is shed on the HMRC argument here. It seems that the UK wants to be the best boy/girl in class, and that its "good" intentions backfire once again:

Within the bounds of its available budget, the Brussels-Capital provides investment assistance for companies that develop environmental projects, including investments in renewable energy plants.

Investments in photovoltaic installations are eligible under the following conditions (Annex 2, Arrêté du 2 avril 2009):

Eligible technologies

Crystalline panels shall meet the requirements of the international standards IEC 61215 and have a minimum efficiency of 12 %
Thin-film PV panels shall meet the requirements of the international standards IEC 61646 and have a minimum efficiency of 7 %

Ammount

The amount of the investment assistance depends on the size of the company (Art. 24 Arrêté du 2 avril 2009):

Micro and small enterprises: 40 % of the eligible costs
Medium enterprises: 30 % of the eligible costs
Large enterprises: 20 % of the eligible costs

Moreover, the subsidy can be increased by 5 % if the company is certified Emas, ISO 14.000 or "eco-dynamic enterprise" (Art. 26 Arrêté du 2 avril 2009).

The amount of the investment assistance cannot exceed € 80,000 per company and per calendar year (Art. 22 Arrêté du 2 avril 2009).]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274450#Comment_274450 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16154&Focus=274450#Comment_274450 Wed, 03 Jul 2019 14:32:25 +0100 Peter_in_Hungary Posted By: CWattersDiscovered this today.

My bad.

Yes, that thought occurred to me too. It seems they'd rather pocket the extra money and blame the EU.]]>
