You can install a 800Wh installation without a certification. Your monthly usage is 300 - 800 kWh.

In theory a 800Wh system can produce between 25kWh and 105kWh per month, depending on the location and month of the year.

Re:Decade of the Battery on Tuesday June 11, 2024 @06:35PM (#40652440)
You can find much cheaper batteries. But they will require additional components that are included in the Powerwall, will be less integrated, less pretty to look at, the mobile apps not as pretty, more complex to purchase, etc

Example 30kw for $8k. https://signaturesolar.com/eg4-ll-s-lithium-batteries-kit-30... or https://batteryhookup.com/products/new-24-56kwh-lifepo4-batt...

A tool to get insights into the usage of Github Action.

Starting with basic analytics, then adding the ability to create SLA, and maybe predicting spend.

They can do it, it is just turned off by default and require more advanced configuration.

- monitoring and observability are more complex/require more tools to work and/or extra convention like forcing people to name their queries
In case of an outage, maybe you do not need to heat the whole building.

They start elitist, people love them for it but that's a niche market as the top "1%" is, well, only 1%. So to justify valuation/please VC/increase revenue, they have to increase the pool of candidates which basically destroy the value-prop of their service.

It is possible to do this without battery, but you need some special inverters, like the Enphase IQ8.
Re:Software horror show: SAP Concur on Monday December 05, 2022 @12:34AM (#33861845)
I used to work for SAP Concur, not by choice but after Hipmunk got acquired by them.

Concur talked to us to use our autocomplete DB in their "new" UI because we had better results. We were using the population size of the location to sort bigger place first.

In the end it never went beyond that one call. I think they already had multiple team working on this, not necessary together (there was a big rewrite going full force with micro-service going on).

Re:Software horror show: SAP Concur on Monday December 05, 2022 @12:10AM (#33861728)
I used to work at Hipmunk, stayed until it got shot down. SAP Concur approached us to use our auto-completion algorithm/database to power their new UI or whatever. Apparently the 2 or 3 different DB they already had for that exact use case were not good enough. Our result were sorted by population size of the destination, The concur people could not believe it was that only that.

In my experience, it is less about skills but more about cultural differences that make them appear less skilled.

Installing solar panel above fields to boost the production of both is a thing.

Goats/sheeps are often used to clean the weeds in solar farms https://solargrazing.org/what-is-solar-grazing/

There are also studies that show that solar panel above fields can help boost production of both: solar panel get cooled by the plant perspiration and the plant get cooled by the shade of the panel.
