It’s all theory. That’s why I think it’s worth a try and learn the facts.
Edit: A rough estimation with averages: 10 kWp gives 11kwh a year in Swiss, 1kwp panel costs 500€, 1kwh energy costs 0,28 EUR in Swiss. Panel material costs for 10 kWp is 5,000€ and earns you 3,080€ (11,000*0,28€) yearly. This shows the value of the idea.
Don't forget about the inverters.
Low voltage (such as the output from a solar panel) suffers badly from losses over distance. Centralised solar makes up for this by having a large amount of panels close to a central inverter. There is going to be a distance tipping point of cost vs losses, if this is short and you need a lot of inverters, that's going to become a major expense.
