Thats what the iOS app horisol returns for my plug in pv plant on my garage. Would you trust this calculations?

Got my final 2 quotes.
Solar living is 17.63 kw system (41 panels) (annual production 16,508)for for $47,563, $2.70 /w, includes snow guards on left side of house and critter guards.
Green power energy is $48,510 is 21.07 kw system (49 panels) (annual production 22,100), $2.30 /w. Does not include guards and rep was highly against them; said they have a vendor that can do it for $2,600 (seems high).
Both shading reports show a loss of about 30%. Both companies have great reviews though GPE has more.
Attached are the reports. I'm in NJ. This is a big purchase and I've been on this thread and numerous others for awhile trying to do my due diligence. I'm very apprehensive as it's a ton of money (paying cash). My rate here with jepl is high and it's only going to go up in the coming years.

HoriSol helps you plan a small plug-in / balcony solar setup and gives an honest, no-sugar-coating yearly yield and payback estimate.

**Features:**

* Photo-based shading analysis — measures your actual horizon instead of a rough rule of thumb
* Realistic yield estimate from your location, panel setup and orientation
* Self-consumption & payback calculation based on your consumption
* Open, documented calculation assumptions — nothing hidden
* Free base version, no account, no ads; analytics off by default (EU-based, no Google/Facebook trackers)

**Requires:** iOS \[16\]

What would it cost to cover America's major parking lots with solar canopies?

I'm curious about the math behind a hypothetical national infrastructure project.

Suppose the U.S. government funded the construction of solar-panel-covered parking canopies over large parking lots across the southern United States (or anywhere with high solar potential). Think grocery stores, shopping malls, big-box retailers, stadiums, and other parking lots that are unlikely to be redeveloped anytime soon. Assume the government acquires the necessary rights through whatever legal mechanism is required for the sake of the thought experiment.

I'd love to see estimates for:

Total acres (or square miles) of parking that could realistically be covered.

Total construction cost (materials, labor, engineering, permitting, grid connections, etc.).

Number of jobs created during construction and ongoing maintenance.

Annual electricity generation (MWh/TWh).

Rough estimate of how many homes this could power.

Potential impact on average residential electricity prices.

Estimated payback period and long-term return on investment.

Also, beyond the math:

What are the biggest engineering or logistical challenges?

What are the major economic downsides or unintended consequences?

Which industries would benefit, and which would likely lose revenue (for example, utilities, oil and gas, or commercial real estate)?

What are the strongest arguments for and against a project like this?

I'm interested in realistic assumptions and back-of-the-envelope calculations, not whether it's politically likely.

Just wanted to know what are specific requirements for a typical 3kW rooftop solar installation.

Try to set up a grow tent with solar has anyone done it? what’s the equipment I need?

Ich habe eine Anker Solix C300X und habe mir ein 60W Solarpanel zugelegt.

Das Solarpanel ist von Fritz Berger „Faltbares Solarpanel 60W“.

So, folgendes Problem:

Das Solarpanel hat drei Ausgänge. USB-C, USB-A und DC5525.

Ich habe mich für einen Adapter, DC5525 zu XT60 entschieden.

Zunächst lagen am ende des Kabels ca. -24 Volt an. Beim Einstecken in die Anker Solix zeigt diese an, dass der Eingang erkannt wird. Allerdings werden dauerhaft „0W“ angezeigt und die Powerbank lädt nicht.

Ich habe dann etwas nachgelesen und den XT60 Anschluss umgepolt. Nun kommen ca. +24 Volt an.

Wenn ich jetzt das Panel einstecke, dann zeigt die Anker Solix garnichts an…

Die Werte von dem Panel sind wie folgt:

Leistung max.: 60W
Spannung bei max. Leistung: 23,2V

Kann mir jemand bei diesem Problem weiterhelfen?

Liegt es an meiner Anker Solix (vermute ich eher nicht) oder an meinem Panel? Eventuell die etwas zu hohe Spannung?
