yep - we're past the worst generation wise

Good day yesterday we made 12 kwh up here in the North of Scotland although it has been a poor winter so far - to much cloud.
8 days after install and we are just over 60kWh here. Quite enjoying this solar panel system. Best day so far was 17.76kWh.
Those are good figures, makes a difference having all the arrays facing south!

Good day today with just over 21kWh generated. It'll be a month for me on Thursday and we are currently at 270kWh so going well.
Good for me too, 11.5 KWh, but it's been a good week. Submitting my readings today, I'll post when I've looked at the figures.

Enjoying the sunshine, and the solar cells are doing well. Over the last two weeks I have generated 310kWh, which is about 20% of the toal 1.5MWh generated since installation. Although the panels are not optimally installed, the panels on the North west roof are now contributing to a late evening boost which is a useful contribution. Day was yesterday at 19.7kWh. Peak power was last week when it just reached 2.85 kW
Looking at the consumption figures for the last quarter compared with the same period before the cells were installed:
12/13 - 3/14 - E 821 kWh Gas 4347 kWh
12/14 - 3/15 - E 611 kWh Gas 4790 kWh
So about a25% saving in electricity consumption. Interestingly an increase in gas, but my primary heating method is gas and the winter was colder than the year before.
But I have now switched off the gas heating to the hot water tank, and the heating is turned down and will probably be turned off at the timer at the end of April, so it will be on demand rather than on the thermostat, so I expect my gas usage to drop to near zero for the next 5 to six months.
Monetary savings are harder to quantify as I have changed tariffs, but my dual fuel direct debit has dropped by £15 /month, with a surplus building up, so I expect next year's DD to be reduced by at least a further £10/month; I hope more!

Have seen a solar panel washing service to keep the panels at optimum efficiency. Is that something you have looked at? I can't imagine it is cheap.
No, not bothered. The panels are supposed to be coated to avoid dirt sticking to them, so Im quite happy to let the rain/wind do the work! There will be a small drop off in efficiency, but probably not enough to offset the cost of cleaning as they are roof mounted. I'll have a look at them at some point to see how dirty/dusty they are getting!

Our panels are doing well. As of last night, we were up to 850KWh generated since mid feb. I think the best day that I have seen is just over 25KWh.
I'm still waiting on the latest bill but since they are 6 monthly, I'm not expecting to see a massive drop in this one but looking forward to October's bill.
How much does it cost for solar panels to be installed?Originally Posted by 1stRaven

Those are good figures! Ive just passed 1.5MWh since installation, and as I write this, generating 2.5kW.
Depends on the size and type of the array, and the technology used, and the difficulty of installation, but anything from around £6k to £15k, but those are only ballpark figures.

I paid just over £6k for our split array. Its a 4k system, using the same panels and inverter manufacture that we use on our work buildings. Granted, I didn't pay the extras for web monitors or displays and it is a smaller system but the figures made sense since our standard background usage is around 0.8KWh (large media server and large fish tank) so even a dull day will help pay towards it. We were expecting a pay back time of around 5.8 years.
I broke that record on Thursday, with 26.5KWh in a day. April has been a nice month but not expecting to push the figure up much more with the forecast over the next week.
Ladder and a jetwash would do the job surely?
