I do hope the people buying and installing these kits realise there is no way the system can know what the house is consuming. Hence they will likely end up importing 'leccy from the grid to heat their water. However, this has been pointed out many times before..... :sad3:
I've been calibrating my system now for a few days, and I've noticed that when the tank is getting near "hot" that the immersion element power drops to roughly half of it's maximum rating. My immersion is a 3kW device, and when the tank gets nearly hot I can't get more than 1.5kW out of it...
Interesting discussion. However, if the TIC is taken as the system (inverter output) what happens in the scenario where you have installed 4kw of modules on a G83 inverter, and then want to add more modules, keeping the G83 inverter? What info do you give to your FIT provider? Would you even...
The Sunny Backup product incorporates its own inverter, hence nothing is piped through your generation meter when in "backup" mode.

If you suffer a grid outage during daylight hours, then your Solar PV array will compliment the output from...
If you use your existing inverter then your total generation meter would also clock up your night-time usage! I'm sure your FIT provider would notice soon enough that your system was out-performing its targets by a considerable margin...
Hmm, I'm a bit confused now. That document seems to say that development is NOT permitted if the installation is solar PV?
Class C
Permitted development

Indeed, I have 10 panels facing south (with some shading), 3 facing east and 3 facing west. The only solution that made sende was Solar Edge and it's doing exactly what it says on the tin. I'm very impressed with the performance.
Each optimiser works with all the the others to create a...
My planning application was in Sept last year which predates the document in your link. At the time my local planning dept advised that permitted dev rights for Solar PV had been removed when the property was built. However another installation of mine in the same village, also within a...

So does it monitor household consumption and only turn the immersion on when there is sufficient excess? If not, then there's a real danger of importing expensive electricity to heat your water...
With optimisers on each panel, the bypass diodes aren't going to do anything to help you at all. Basically if a panel is shaded it won't produce. See the plot below from my system. You can see the power curves for two Sanyo 235W modules mounted portrate. One is unshaded (apart from the...
Good Energy vote from me too. They even give you cake and champagne!

Here's what my system is up to. This is a plot from yesterday, a perfectly sunny day. One panel is east, one west and one south. It's fairly obvious which is which! All panels are about 42deg.
Why? If you're variably feeding it then it doesn't make a difference what size the immersion is, except for the fact you're artificially capping the max power you can dump into a 1Kw element...
Something like this perhaps ;-) (The washing machine's on so nothing being fed to immersion in this example)
Here it is feeding nearly 1Kw to the immersion (which is a 3Kw element), now the household consumption has dropped.
Take a look at SolarEdge. Similar principle but a simpler power tracker behind each panel which present a constant string voltage (350v-ish) to a single inverter. Has all the same benefits as Enecsys from an optimisation / shading point of view. I have two installs with SolarEdge and am very...
