E7 tariff free at night, solar panels yet STILL paying £117 a month! How?

Further update: I've switched to Bulb. Many thanks all, for your help - your comments made me go through the figures more logically.

If I am reading this correctly your daytime consumption from 25 Nov - 25 Dec is 543 kWh. That is high.


The change in tariff based on that month is a 22% increase largely due to the hike in standing charge. (£105 - £128) so your monthly payments are in the right ball park.


Your minimum daytime use is 9 kWh, and your maximum nearly 33 kWh. There are 18 days over 16 kWh, and 4 days over 24 kWh. I'd suggest this is more likely to be washing machine and tumble dryer than aquarium. You have the data so you should be able to spot the difference between a day when you use 32.9kWh and one when you use 9kWh.

Update#100!

I can't save on Ebico's tariff, after all. Did some better quality number crunching.

Only problem is I have to keep under the 60%. I'll see if I can squeeze a bit more out of the tariff, but it's unlikely to be much.

I am using 41% in the day and 59% at night. Reckon I've squeezed as much as I can out of it!

So in a perverted way if you reduce you daytime consumption then you've got to reduce the night time consumption as well to maintain the proportion.

Sounds like hard work for no real gain - what happens when the sun comes out and you use less daytime leccy, do you have to reduce your night-time usage to compensate.

You still seem to be using a lot of leccy during the day, even 4783 in a year is an average of 13kwh/day especially as it's not heating the house or producing hot water.

You need to do a bit of an energy audit to find outh whats using it all (both day and night) so you can monitor where it all goes and do something about it.

I've just done some annual calcs:
Day
Sep-Dec 2916.9
Jun-Sep 1167.6
Mar-Jun 1216.0
Dec-Mar 1182.0
Annual total Day rate: 4783
Night
Sep-Dec 1406.9
Jun-Sep 345
Mar-Jun 1649.0
Dec-Mar 3297.0
Annual total night rate: 6698

Sorry but the totals of the 4 periods you have posted are 6483 Day and 6698 Night, at a ratio of 49% / 51% Also the day units for Sep / Dec is 2.5 times the average of the previous 9 months.

I'm not aware of anyone on Night Owl who has been bumped off the tariff for using in excess of the 60% night rate limit. Ebico do not seem to enforce this. So I really wouldn't worry if you go a few percent over in the winter months. Once the heating goes off in the spring, you'll be way under 60%.
