    Carport solar is a terrible idea.

    1. Increased height for structure, likely increased weight as well since you need to make super-duper sure they don’t pancake somebody’s car. This leads to;

    2. MUCH greater chance of property damage and resulting payouts (not to mention the risk of somebody’s Timmy managing to shock themselves)

    3. Harder to build and maintain due to number 1, as well as having a bunch of cars around, needing to schedule lot closures, etc.

    4. Number 3 gets in the way of actually using the parking lot as a parking lot, which is probably going to be pretty unpopular with the property owner and/or lose them money from decreased business.

    5. Oh yah, harder to angle due to the constraints you’re under, so less efficient.

    All this adds up to making it a lot more expensive than just putting them on the ground. We have TONS of abandoned malls and supermarkets all over the country, just use that smh.

      1. It’s either a roof structure by itself or adds another ~3cm of height to an existing roof.

      2. You vastly overestimate the weight of solar panels. The ones shown probably weigh ~20kg, and probably ~35kg with framing etc. Most car roofs are rated to 30-150kg of dynamic weight. In the statistically highly improbable event where the structure completely collapsed it certainly will not “pancake” anything and will likely just be cosmetic damage.

      “somebody’s Timmy managing to shock themselves”

      No more dangerous than any of the wires that are, probably, within a few meters of you as you read this.

      1. “Harder to build and maintain” sure, but not by much and nothing requiring the full lot closures you’re imagining.

      2. “harder to angle” Sort of, there might be instances where a suboptimal angle results in better aesthetics, cheaper materials, snow clearing, etc. but we’re talking ~10-15% efficiency loss.

      Based on the shoddy logic and non-existent research I’m guessing this isn’t really about the solar panels. You wanna share what the deeper concern/peeve is?

      What insanity is this, have you ever been in a parking garage where most are like 8ft ceilings. Most solar car parks are well over 12ft and no issue with building them. Yeah it’s more expensive to build solar car ports vs ground based but you don’t need to build big transmission lines which delay or prevent many large solar fields. Then hopefully you can have EV charging stations right there power cars off the sun.
