What are YOUR solar PV's generating TODAY?

as of last night (28th June), Best June since install back in 2011 with a 2nd qtr rebate of around £750  to come

May was still better though so the heat on the panels is obviously having a slight impact

Still this month is shaping up to be the 2nd best month ever since 2011 install with 2018 so far lagging behind 2014 and 15 overall with regards to generation/rebates

Out of interest, what diverter are you using.  Just having a,little read up and noticing that the Immersun one (for example) can divert power to other heating devices like a pool or a hot tub whcih certian makes more financial sense.  

I also like the fact that it has an app which also moinotrs solar generation and export which means its easy to access the data and as the monitoring cable is hardwired, you arent constantly rely ing on batteries behing changed and the wireless conenctionchecking every 10 seconds or so as opposed to a wired solution being constant and therefore more accurate (or so youd like to think:

Yep! June looking like it will hit the same as last months production of 2MWh!....

@jouster our pv installer put in the 4-Nocks power reducer (Power Reducer | 4-noks).

This doesn’t have the remote control app.

I would guess that the Immersun is the leading product in the market.

Mine works well in terms of generating oodles of hot water. But the interface (such as it is) leaves a lot to be desired.

Hi over 600 kw last month and should be well over 600 kw this month two record months

my solar water heater tubes producing abundant free hot water keep shining my sun

One thing that confused me was that if I’m reading correctly, all of these diverters constantly use all of the available excess generated power to continually heat water.  

How does that make any sense?  And what happens when battery storage becomes viable pice wise?  Will this not be totally counter productive?

What size system have you got.  Great generation amount on your setup

@jouster diverters are kinda poor mans batteries. You get to self consume / store a lot of the energy you produce. The energy you generate first goes on what your house is consuming. So generation goes on base load, washing machine, ashp etc. Any spare electricity beyond that goes onto the immersion heater in your tank and heats up the water there. So on a sunny day you have lots of extra hot water, most of which you’ll consume after dark and maybe next day depending on the size of your tank. You need to set the thermostat on the tank at a level that is safe / not too hot. Some systems have dedicated thermostats for this.

When battery storage gets cheap you probably won’t need a diverter, but obvs a battery is £2.5k - £7k and a diverter is £200-£300 so there's a long way to go before a diverter isn’t economic. But I’m still very interested in a battery.

Btw I’d have really liked to have solar hot water as well, that’s really cost efficient.

I think this is what people on gas mains are all waiting for, a drop in battery price plus the ability for the battery to top up overnight on cheap leccy. Hopefully battery prices follow solar panel price drops.
I'm not sure but for people off gas the economics might be close to be workable?
