Wow! Seeing some of these power costs is amazing.
We have a 13.2kw system and our power cost has been around $35 per month, since installation, with the last one being $42, due to the increase. I also have the old HWS on a timer, which means it heats from the solar between 0900 to 1130 and we've never been short of hot water, day or night.
We are on tank water, so don't take 10 minute showers, though.
We had a 13.2 Kw Solar System installed back in March which was just after the Smart meter was installed & reading taken. We will see what our next account will be. I was also talking to the guy next door who works for Ergon about our Heat Pump& he suggested we fit a timer.Quote:

We run a 5kw system and don’t get bills.
Gas bill gets paid from credits. And it’s sub $100 per quarter
Because we're on tank water, every time we have water use, we have power use from the pumps.Quote:

No bills for me either with 5kW, I don't have gas but do have solar hot water, I actually get credits but that is with the good feed in tariff, although the system pro'ly cost 4 times what it'd cost today.Quote:

What is cool is that I used almost all of the Solar power at work[thumbsupbig][thumbsupbig][thumbsupbig][thumbsupbig] I am making over 5 kWh per day (Its winter and cloudy) Some days are well over 10 and others here in Mexico go LOW [bigrolf]
Booking the sparky for coffee and doubling or more the solar on my roof. Every inch possible this time! I had him looking for me for a few weeks now. Rotten sod is to busy[thumbsupbig]
Hold, repurpose or sell the existing panels will be fun to chat about.
Hopefully your present inverter can take two arrays or strings at the new full generation power input, otherwise you might have to get another inverter or an inverter with two arrays to keep old and new panels together as they have to be matched IIRC.Quote:

We need or like hot water. My heat pumps are apparently good? My power bill is also[bighmmm]
Personally I think heat pump water heaters suck and would never have another nor would everyone I know that has had one. Noisy too. There are some extremely good and very efficient gas heaters with condensing and heat recovery tech that are over 90% efficient and produce almost no waste heat which is amazing. Of course the downside is they are over $5,000...
When my current heater goes I will finally put in a solar hot water system but these only have current crappy tech instantaneous gas boosters on them which is still needed in the Winter here - when you need more hot water... [bigwhistle]
Waste not, want not
By allowing customers with excess generation to sell it to those without panels, she says, both sides of the transaction might just end up winning.
"Using the existing poles and wires, people who have excess energy from their rooftop solar can sell it to their neighbour or a local cafe," she says.
"They can get more, hopefully, for that energy that they sell than they otherwise would.
"And the cafe or the neighbour can buy energy at a lower price than their current retail contract."

Must be better than the feed in Tarrifs [biggrin]
