There’s a fibre outage in my area and since it went down I haven’t been able to access any data from the inverter via mySigen app, but for some reason that my little brain can’t comprehend, I can see all the data from the inverter in home assistant. How does that work?

Also, any idea how to reclaim control of my HWC and EV charger that are routed through shellys and controlled through the mySigen app?

I am playing with an idea of solar panels. I want to calculate solar generation vs consumation based on my actual smart meter data (30-min frequency) and actual sunshine data for my location, not general estimates. Is there a site/app where I can do that? Has anyone tried OpenSolar or Pylon? I've heard that Harrisons often overestrimates solar generation forecasting.
Appreciate

10.5kW of Panels have the option of either a 8kW or 10kW inverter. Have been approved for 10kW export limit. $600 price difference.

Thoughts?

Update, now a $150 difference between the different sized inverters.

We are in Franklin ( Counties Power ) and figuring out what size solar system to install. Current thoughts are a system that would have 14kw export and maybe 20kw-25kw of solar panels. This would give us maybe 60kwh of export on nice summer days. Looking for any advice around doing the DG2 or limit our export to 10kw and do a DG1, also are the power companies happy with people supplying that amount of power?

I have a system with a sigstor10 and it was initially set up by the installer or sigenergy to stop discharging at 20% and charge to 100%. I changed that to 17-97 on the thought that charging to 100% may not be the best setting for battery health. I've since changed that to 15-98. Really curious what others are doing and thoughts on the setting in general. My grid supply is very stable so it's not like I spend much time off grid anyway.

Considering a 10ha solar farm near Chch. Any thoughts of the best companies to sell the energy to for the highest return?

Hey everyone, looking for some experienced eyes on a solar quote we've received. Wanting to make sure I'm not missing red flags before signing.

Our situation

We're a family of 4 in Christchurch, NZ. The house is a bit unusual which I think pushes the price up:

• 4-storey cascading hillside home on a sloping section in Cashmere
• Architect-designed, built 2016
• Butynol membrane roof (grey 1.5mm fully adhered over plywood, 2° fall)
• Multiple separate roof areas across different levels: L0 garage 50m², L1 entry 132m², L2 living 71m², L3 bedrooms 66m²
• Quote covers panels on L2 + L3 only (top two levels)
• Currently single-phase 63A supply (consent plans originally specced 3-phase capability but only single-phase was installed during construction)

Energy usage (verified from 12 months of half-hourly meter data):

• 14,044 kWh/yr currently
• Annual energy spend was ~$7,247 ($5,967 electricity + $1,280 LPG gas)
• We've since switched to Mercury (27c peak / 15c off-peak / $2 daily) which dropped electricity to ~$3,500/yr
• Planning to transition gas to electric (Rinnai 340L heat pump hot water + induction cooktop) which adds ~1,800 kWh/yr
• Post-transition total usage: ~15,844 kWh/yr
• Two heat pumps for heating (no central system)

The two quotes from the installer

Option 1 - No Battery: NZ$29,871 inc GST ($2,464/kW)

• 24× Suntech STP505S-H54-Nfb+ panels (505W each = 12.12 kWp DC)
• 1× SigenStor EC 12.0SP single-phase hybrid inverter (12kW)
• Estimated annual generation: 13,919 kWh
• Installer's Y1 savings estimate: $2,963
• 25yr panel product warranty, 30yr performance warranty
• 10yr inverter warranty

Option 2 - With Battery: NZ$42,586 inc GST ($2,635/kW)

• 32× same Suntech panels (16.16 kWp DC)
• Same SigenStor EC 12.0SP inverter
• 1× SigenStor BAT 10.0 battery (9.04 kWh usable)
• Estimated annual generation: 18,385 kWh
• Installer's Y1 savings estimate: $4,090
• Same warranties

Payment terms (both quotes):

• 50% deposit on acceptance
• 25% 7 days before install
• 25% on completion

Installer has confirmed full roof setup is included (scaffolding for 4-storey access, butynol membrane considerations, all labour).

What are our thoughts? Ive got a few quotes still to come in of course!

I’m currently going through quotes for a grid-tied residential solar install and I'm keen to understand any insurance implications.

My current roof is long-run colour steel and is 10 years old, I'm in Hamilton so harsh environmental conditions (salt, sulfur etc) aren't a concern. I've been up on the roof recently to spray some patches of lichen and my untrained eyes couldn't see any areas of concern.

Things I’m curious about:

• Did you disclose the solar install to your insurer?
• If yes:
  • Was it a new build or retrofit?
  • How did it affect your premiums?
  • What region are you located it?
  • Did they require any extra documentation/certification?
  • Did they specifically ask about batteries, EV chargers, backup capability etc?
• If no:
  • Was that based on advice from installer/broker/insurer?
  • Any concerns around future claims or non-disclosure?
• Has anyone changed insurer because of solar?
• Any insurers that were especially easy/difficult to deal with?

I would really appreciate hearing real-world experiences from people who already have systems installed.

To be clear, I'm leaning towards disclosure to be safe but just wanted to hear about other peoples experiences.

Thanks in advance!

I have 29 panels on the north facing side of the roof. It's working for us but as winter approaches the sun is lower and it's obscured by tall trees so we only get full solar at about midday (rimu and totara... Not cutting them).

Our garage roof is in sun all day, so was thinking of a cheap way of having about 4 panels up there.

I was reading about the European plug in systems. Will they get over here? Haven't seen anything yet.

Just had solar installed and Hanergy’s rates seem good, but I haven’t seen any reviews other than google ones which look kinda fake. No contract, 18c export, 30c anytime import, 168c daily. Any experiences out there?

Buy a piece of land, whack some solar panels on it and try get it to pay the mortgage?

Maybe build your house of the land when you've had enough of it.

What’s seems to the normal deposit amount in this industry, I’ve seen 50-60% asked for. That seems pretty high to me, because if they go bust you’re not getting that $$ back. So I’m assuming they essentially use your $$ to buy the product.

We have 2phase house so we are looking at Sigen 3phase inverter as one option. It’s the 15kW 3 phase inverter but will apparently have only 2 phases active.

What is the continuous output per phase of this inverter?

Will it be worth waiting for a bit longer expecting vector to lower down their fees for larger systems in Auckland?

With the default export limits going higher and more ok flexi type, it should be pretty common for vector to get more and more connections that need 10+ kw generation and export limits.
