No one is talking about the grid connection and batteries though. You will need batteries somewhere because demand and supply don't match.
Then there is servicing the solar. And engineering/architecture bespoke to each case. I can see how a large solar farm might make all that more efficient.
Put it this way, home solar is not always a no-brainer, financially, and that doesn't usually involve building a structure, just attaching them to a roof.
- ncmncm 4y agoHome solar is strictly more expensive than utility solar. If your area allows you to opt into power from a solar farm, and pay the solar farm's rates, jump on it.
- quickthrower2 4y agoWhy is car park solar not more expensive then? Say you have 1000 car parks, 1000 plans you need to send to local governments, 1000 architectural plans to deal with, and son on. Some of the things will scale but a lot wont.
- ericcumbee 4y agoif you own 1000 parking lots you already did that, if you pulled a permit to repave them you've done it again.
- quickthrower2 4y agoRepave is a different thing to build. You are changing the landscape. NIMBYists can have a say, for example. Also who said one person owns 1000 lots. I am saying there are 1000 separate lots we want to solarize, vs. a plant. If they are owned by different people, then you need a business to market, educate and sell this to them etc. Which is another layer.
- prawn 4y agoFor commercial installations, demand and supply often match very well. They're not trying to get off grid but reduce bills. Whereas many homes with working parents and school age children are using power after sunset, for offices and shopping centres, they're running something like air-conditioning while the sun's up. Where I live, home solar pays for itself in 4-5 years; for our office building, it was 3-4 years.
