Balcony solar PV

[Joeboy]

I have just bought another 10 from City Plumbing.
Ive got no Idear why.

Ah man, I love that!

The way prices are atm if I was in UK I would be fitting a couple of vertical panels on the South elevation of my house and building a canopy above the West facing kitchen window / door with another couple. As I'm not there and probably won't be there long enough to do the work in the foreseeable future my daughter will have to do without.

At least she must benefit from what is already installed.

I plan to fit 4 400W panels to the tiled roofs of the one storey "porches" but they also point WSW as the original fit panels, far from ideal and I want to remain compliant even if I have no approval. This is why I am looking at the Hoymiles 1600.

My thinking is if I go for the 5kW hybrid in an ESS arrangement with the export limit set to 5.68kW that I have approval for (fitted by a qualified electrician) then what additional AC generated will never get past the hybrid if the battery is full.

I need to understand how my solarmax fit inverter and a hoymile 1600 will deal with the hybrid inverter saying no more.

BTW my additional 1800W facing SE commissioned in January as a battery charger with inevitable curtailment has produced 930kWh so unlikely to get the 1MWh by year's end.

Why has PV taken a price nose dive in recent weeks/months?, US and China relations seemed to have thawed a bit recently, but felt sure there was going to be a big hit on exports

Long may it last

Could be oversupply post Covid spool up and a segue into seasonal drop off of demand. There have also been a good few efficiency increases lately. Not sure how long those advances take to filter through.to general PV manufacturers. That would make existing supplies old stock by Spring?

I hope it continues, I might get a few more panels to sit in my garage for 'project_fence_something_or_other'

Agreed, at these prices it would seem silly not to wouldn’t it. Definitely on my Christmas list.

Several reasons.

- Silicon dope has dropped to silly levels per kilo.
- Advances in Perovskite panel technology is meaning anything less than 25% efficiency now is deemed old tech.
- Oversupply. The cost to produce the panels now is actually on par with retail sale value. It can't continue like this. They will stop production until demand increases and so do prices.

The next thing to see a sharp drop in price will be batteries, once carbon batteries gather momentum in production.
I could see Lithium batteries halving in price overnight.

Thanks for that, shame about the batteries ^^ since I'm in the market for them

After working in IT for 25 years and having more than a casual interest in networking, data storage and computing in general, I came to the conclusion many years ago that you cant keep holding out for the next price drop or spec increase or quantum leap, because there will always be something better, cheaper and faster around the corner.

if you need or want something after doing your homework, unless its a new iPhone or something 5 days before a new model is released etc, just get it and try not to reflect on it when xyz comes up 20% cheaper the next day.

I've just ordered my Hoymiles 1600 from Germany via Ebay - have to see how long it takes to wade through the customs process.

In terms of Hoymiles and current inverter playing together, I currently have a 3.68kW Sunsynk inverter system, with CT coil and DNO agreement to export up to 3.68kW.
My assumption is that the Hoymiles, which has no CT coil, will keep producing regardless - so say the house is using 600W, and the Hoymiles is at full power - it will export 1kW to the grid.
The Sunsynk will read the CT coil as exporting 1kW, so it will allow an extra 2.68kW to be exported to reach the 3.68Kw limit, and anything above that will either go to the battery or be lost, as it can only control the export using the reading from the CT coil.
