Ask HN: Do you have home solar?

I do, feel free to DM on Twitter. Just pull an 18 kW system in a few months ago and it’s been great.

(Full disclosure: I’m in the solar industry, but on the software side. Recently left Cloudflare to join Aurora Solar as CPO.)

Consider talking with the folks running NREL's SolarAPP platform. Potential partnership opportunity considering the data flows in scope for automated permitting.

I only have solar!! It’s awesome. Completely off grid. Sailboat life.

No, but when the roof eventually needs repair we probably will. Sounds like an interesting idea though!

Germany is steadily reducing the legal hurdles to install balcony solar plants. Now one does not have to ask the landlord for permission, no tax, 800W allowed, etc..

Berlin grants one 500€ with the purchase of a balkony solar plant.

I've got a pretty old 7400 watt system installed back when the incentives from California were pretty good. It's lost quite a bit of efficiency over the years, and usually tops out at around 5200 watts, providing ~40KWh during cloudless days in the summer. I don't know much about net metering and incentives, but what I do know is that I can't make any major changes to the installation without ratcheting down to the current regulatory system, which reduces compensation for selling during off-peak hours.

Can you setup a form to allow us to upload the docs? I had solar, panel, and roof done by SolarCity before it was purchased by Tesla.

OT but what's the best way to find incentives and rebates given a zip code? Google just suggests 1,000 ads...

I’d be happy to help. My email is in my profile

I put solar on my roof right before the NEM 2.0 -> 3.0 switch over. Email is in my profile.

Do incentives and rebates apply to batteries as well?

I do, self-made (legal here, France), composed of:

- 12x Trina Solar Vertex S 400Wp (TSM-400DE)

- solar inverter Fronius Primo 5kW

- battery inverter Victron MultiPlus II-GX

- 8kWh LFP BYD LVS

- smart meter (zero injection setup) Victron/Giavazzi ET112

- EV charging piloted by the Victron (EVC300400300)

There was not much 400V batteries and inverters back than. I log a bit via Home Assistant, so far without InfluxDB simply because I still have to find value in logging over longer time period, pruning data etc and HA alone was time consuming to setup due to the devs passion for YAML (GRRR i HATE modern YAML mania).

Personally in commercial terms I'm DISGUSTED by the current state of thing where in China prices plunge and here in EU skyrocket, as quotes from professional installers are so high that a not-self-made system is simply economically not a good investment.

Feel free to ask what you want :-)

I have home solar. I'm interested

I expect to by September. DM me.

I had my panels installed in 2018. I doubt there's any incentives at this point? Are you looking for more recent installs?

Plz shoot me an email, collect.metadat at gogglestermale.

P.s. this thread would've been less noisy if there was a decodable email address in your profile, sweetie pie. :)

Then again, maybe you know the trick where more comments is mo' betta'. No judgement, haha.
