How is Solar PV saving me money?

No, you are using 1000, but you are producing 500. So you are paying for 500 only.

Understand your new meter does not DEDUCT the generation from the load. It only shows what you are using AND producing. 2 separate figures.

Hi Lee,

So I thought that any solar generation energy would be used to power the house first, with any additional draw/requirement coming via the mains.
Therefore I was expecting the electricity meter to register less usage while generating, and therefore reduce my electric bill.

It is being used, the meter just doesn't display it that way.

Your meter that the distribution company supplies (the one you have always had) will show less energy being used. It will spin slower, stop or blink less if it's a newer digital meter.

The 'evergy monitor' you have just installed will only monitor load and generation. It will not calculate the difference between the 2 and display the difference. Only what you are currently using and what you are currently making. It 'may' give you some indication if you are using all that you are producing like mine.

You can be assured that you are saving on your bill. Wether you are turning a profit is a very different question.

Does that make sense?

Think of it this way...

Your new 'meter' gives you real time information only at a glance. The savings will be seen on your old meter when the little man in a van turns up and records a lower number.

Ahh, ok I think I the penny has dropped now!
So, I won't see the reduced mains electricity usage directly through the Smappee monitor (compared to pre-solar), just the two values, generation and consumption.

 

[LeeH]

Simple as that.

That Smappe looks a nice bit of kit.

Crikey, I got there in the end! Thanks for your perseverance!
Yes, so far the Smappee is working really well. It's starting to distinguish between devices as well which will be really useful.
