Some pics of our commissioned on Tuesday PV install in the North of Scotland.





13x235w Yingli panels
Sunny Boy SB3000 invertor

MCS accredited installer and equipment

Saw 3.02KW peak output on day 1
15KW/h produced today day 2

Now trying to tailor usage to production as much as we can during the day - possibly a bit easier as people at home during the day.

Washing machine, dishwasher, Breadmaker, slow cooker etc.....we averaged 7kw/h per day consumption over the first 150 days of this year - giving an estimated 2500kw/h required for the year -  our (SAP) estimated production is ..........2500kw/h. Watch this space  Cool

Nice one.

Welcome to the forum and keep it up.  Depending on how you're set up you can even try to do your hot water with spare power during the day.  I've got a semi-automatic immersion heater and Alan (resident electronics genius) has come up with a very snazzy 3kW heater controller that draws variable power (not just on-off like mine) to soak up just the right amount of juice to balance production.

http://www.navitron.org.uk/forum/index.php/topic,10296.15.html

http://www.navitron.org.uk/forum/index.php/topic,9072.0.html

http://www.navitron.org.uk/forum/index.php/topic,8368.120.html

The idea in both cases is to try and figure out what power is "spare" and divert it into your hot water tank to save using mains electricity or gas to do the job.  His one is more relevant to you as it is for a grid-tied system whereas mine is for an off-grid battery system.

Cheers outtasight,

The 6msq Solar thermal gives us excess hot water through the summer (full50+ degree 210l tank yesterday). We also have a back boiler on the 5KW Wood Burner with coil in tank. This combo means no oil has been used for water for nearly a year  Grin

The "divert electricity if not using" option is something we do want to investigate.

Ahh... Is that what the three panels are in between your PV panels on your second piccy... water heaters?  I thought they were just windows!  Silly me.

Another possibility is getting a storage heater and using the spare juice to "charge" that up during the day for use at night.

@tange

We put our deposit with the installer three months ago so we had a lead on the queue when they arrived.

I understand The Powerstore are his supplier.

You might want to put your meter readings into bdpv.fr (as there isn't an english-language equivalent SFAIK). Use it via google translate if your French is insufficient. There are a fair number of other Navitron PV owners on there for you to compare against.

Nice one Mikey,

who did your install, we're looking to do a similar one in the highlands on a new build and MCS installers seem a little thin on the ground.

Cheers, Paul

Paul,
We used Tom Morley - at Solar Tech in Edinburgh - when we were looking for someone to come and quote - he was up a week or so later (I did get him 8 visits in the Highlands) - however they appear to be working across Scotland and beyond - doesn't seem to be afraid of putting the mileage in!!

Am a fan of the blog by the way - and had a great few days on Raasay in the camper a couple of years back - the blog brings back memories  Grin

Hi Mikey,

thanks for that, will give him a call, did you do the flat plate collectors yourself ? I'm seriously thinking of going down that route rather than toobs. I know they're a little less efficient but they do seem much more robust and unobtrusive. I also like the idea of less area to slate on a new build  Grin

Cheers, Paul

mcgill electrical in dundee also carry out installations, Main office in Dundee,and smaller offices in Dalgety Bay, and Glasgow, been around for 30+ years and arent going anywhere, with a view to warranties etc.

http://www.mcgill-electrical.co.uk/index.php/renewable-technologies


I would imagine that sending detailed photos of your house, roof, fuse board, etc potential inverter position, distances between these items  etc.

this will all help with a off site survey

Regards

Tony
