The landlord gets out their original investment plus 150% roughly.
I actually think many tenants will end up with large bills because they don't be able to tell or perhaps fully understand when the electricity is free. I doubt many social housing landlords will be paying for remote displays for the tenants! So many will have no way of knowing.
End up with large bills - why, for what?
So many will have no way of knowing - MK1 eyeball and window?

If you had never seen a PV output display do you really think you could guess form a PV array with any degree of accuracy?
I'll bet there are people on this form who will end up having larger electricity bills after telling their partners to use the immersion because it's "free" while the PV is working and the partner doesn't understand the suitability of PV output. The difference is that they probably have a remote display (or at least a display they can read) and can afford it the electricity bill when it comes.
If you still think the eyeball is good enough then why are people paying £100 for remote displays?

I'll bet there are people on this form who will end up having larger electricity bills after telling their partners to use the immersion because it's "free" while the PV is working and the partner doesn't understand the suitability of PV output. Like any new tech, people will learn about it quickly. Anyone using an immersion heater in conjunction with PV is taking a big risk. A quick chat / google will inform most how to 'get along' with PV. If the immersion is being used anyway, PV will help. If it wasn't being used before, then it probably shouldn't with PV. Simples.

PV will eliminate about 10 to 15 hours of baseload in the summer and 5 to 7 hours in the winter, 1 to 2 kWh's per day unless the weather is terrible. Even without trying, anyone, can save 300 to 700 kWh's depending on baseload. Remember PV will service the house (baseload) before exporting. A householder would have to switch off all fuses at dawn, to avoid baseload savings.

Further tips when the sun is on the PV side of the house:- if it's hot outside, put the washing machine on. If elderly neighbours are saying 'I like it warm, but this is too warm', put the washing machine on, if you need sunglasses or shorts, put the washing machine on, thinking of having a BBQ or going to the beach, put the washing machine on.
I think you are seriously underestimating how quickly people learn. If a 5 year old can run rings round me with a smart phone, I'm pretty sure someone renting a room and responsible for their electricity bill can learn about PV. It's hardly rocket science.
I appreciate that I'm being rude and condescending, but I'm a little angry at just how ridiculous the statement that PV will increase bills is. It would actually require effort and a large degree of stupidity to achieve an increase.
