Domestic solar PV quotes 2018

Question around the grant side of things. The portal makes it look like all the dealing with documentation/forms is done by the contractor? Is that correct?

I know when we got insulation done the forms for declaration for works and the like were sent out to us, but this seems to be different?

mike_2009

I had to set myself up on the SEAI site, find the contractor and then they did the rest. Could see when the docs were all uploaded and then just had to wait for signoff and the grant to be paid out. The contractor should pull all the photos and docs for you and submit them.

I was getting shading on my panels so got the installer back to fit Tigo optimizers & wow what a difference.
Produced 33.5 kwr from my south facing 6KW system yesterday

Surprised the installer wouldn't have known before installation that there would be shading issues and optimizers should have been installed from the beginning.

They installed 3 optimizers on the panels most impacted but more panels were getting shading than imagined especially with the low winter sun

6.2kw SE, 5kw Solis hybrid inverter, 7kw BYD battery

Yesterday 31.4kw, eddie 7.5kw and the dreaded export of 5kw

Today 25.8, eddie 7.5kw, exported 3.8kw

Total exported this month 55.6kw
Bought in 23.7kw.
Total generated so far this month 379kw.

The boiler has now been switched off, would have done it sooner but had to replace the hot water element last week.

Its on the up and up Ladies and Gentlemen.

Wow, that is good. My 5.8kwo system gave me 23 today and 22 yesterday, and my system issouth facing (well 160deg)

I got some good quotes for my 7 panel installation. I need to get a bigger water tank for my family of 4 as 120l is a bit on the low side.
Th PV installer said to get a plumber to fit a tank.
Any recommendations?
200l or 250l?
Steel or copper?
Plumber tells me I need a vented system

unkel

I got a 360l highly insulated Joule cylinder installed when I got my solar thermal tubes system installed. The standard 120l cylinder was already ridiculously small for our family of 5 (4 females) because of our pumped shower.

Anyone on here have a Solis hybrid inverter that can advise how to switch modes for battery charging. My system seems to be charging my 2.4kWh battery overnight meaning that on a sunny morning the solar diverter is heating water from 8am and I end up exporting by lunch time.

Preferably I want to charge the battery from solar first thing, then water and then charge my PHEV.

unkel

Did you read the manual? Should be fairly straight forward. Also, do not heat your water as a higher priority than charging your car. The former is worth about 5c/kWh, the latter about 8c/kWh

Also, do not charge up your lithium battery with night rate electricity if you think that you save money doing so. You won't. The sums have been done on this on this forum before, do a search. It will be more environmentally friendly to do so as night rate electricity in Ireland is on average >50% from renewables, so if that is your main motivation, go ahead!

Looks like you have time charging enabled.
Also I found that sometime even if you disable it it does not work better to adjust the time.
Go to advanced settings/storage energy set/storage mode select/time charging
change optimal income to stop
also you can modify t_charge to the same time so total time is 00:00
save settings and this should stop charging

Hi Eamon,
Yes, I have a Solis Hybrid 4kW inverter and 4 x 2.4kW Pylontech batteries, and think I have just about understood how to get them all working together.

On the Solis, go to Advanced Settings, enter the password, go to Storage Energy Set, then select Storage Mode Select, select Time Charging, then ensure that Optimal Income is set to RUN (this is the 'auto' setting where the Solis will charge the battery if there is sun as full as it will go, and not discharge the battery when there is no demand etc - works fine with my set up. For good measure you might the Charge Time start and stop to 00:00:00 and Discharge Time same - all zeros - but I think these settings are only relevant if you change Optimal Income away from RUN. Put in those settings, and your battery should certainly not charge up overnight (hope you are on a night rate tariff or that will be costing you a lot, both in electric bills, and on needlessly cycling your li -ion battery!)

Go back to Battery Select, select Pylontech, hit enter, then see what your Ovcerdischarge SOC is set to - from what I have been told, for a single battery this should be around 25%, probably not less than 20%. And the Forced Charge setting - the next down when you press enter, should be at at least 10%.



Let me know if you have any more queries, you can send me a PM if you like. David

According to the manual 'Auto mode' is active only when all other 3 modes(time charge, off-grid, battery reserve) are off.

I did not notice that you had already replied to that question by reklamos. The manual is a classic example of an attempt to translate a tech document originally written in Chinese to English and a lot of it is not really very clear. I have my system currently set to Time Charge =RUN, but all time settings set to 00, and I think that is equivalent to having Time Charge = STOP, anyway, my system working great at the moment the way that I have it

Post the link but just change the http to htxp or something so it doesn't look like a link. We'll figure the rest out!

That worked perfectly. My battery charges from solar only now, as I expected. Why the installer set it up to charge from the grid overnight is beyond me.

If you have a day & night rate meter, it makes sense to recharge the batteries in winter with night rate, and use this power during the day. Depending on size, you might get most of the following day on solar and battery, before reaching 23:00 when the next night rate period begins.

Have an offer to stick on the Eddi to my system for 500 quid, people think it is worth it? thanks

Far too many variables missing to make a judgement.

How do you currently heat your DHW?
How much of it do you use?
How much does it cost to heat?
How much do you pay for daytime electricity?
Are you home during thr day?
What's your annual electricity consumption?
What's the projected production of your PV system?

I could go on.

I added an iBoost which does the same job, people state that it will never pay for itself which is one point, we use it to heat the sink element which means constant hot water these days rather then escape to grid, the house is occupied through the day, it's great, go for it if you don't mind the cost.

How do you currently heat your DHW? I use either immersion or its on the oil heating. It is heated over night(electric) and 1 hour of heating oil every evening
How much it do you use? We use ALOT of water
How much does it cost to heat? No idea.....
How much do you pay for daytime electricity? We are on a night rate meter, 0.219 per day kWh
Are you home during thr day? Most days
What's your annual electricity consumption? last year just under 14,000kWh Day & Night
What's the projected production of your PV system? No idea on projected, we have 19 panels 300watt

You have 6kwp right and a family of at least 4-5?

Go for it, but get rid of all your electric showers asap

:eek::eek:

You need to start pricing around, particularly since you are consuming several times the average!

air

You'd possibly get good use out of it but your electricity usage is huge so I'd imagine your self consumption is high already. This reduces the ROI on it.

It's Energia, I nevre know how to read the bill. It was a cheap rate, after the rate they have a discount amount listed against entire bill.....cant see what the exact rate I do have
