@hweimer When you have solar on your roof, you can use this energy and sell the surplus to your neighbors. But what happens, if all your neighbors have solar on their roof, too? Will there be a market price at all in a solar-powered economy? Or will system costs become the main factor in a calculation? Or will we see negative prices + H₂ generation = zero sum with good weather and extreme prices during dunkelflaute? And can these niches be enough for energy companies to survive?

@AdeptVeritatis @hweimer That's the reason why _building codes_ should nudge construction of East- & West-facing roofs, or the South-facing ones to be relatively vertical towards the winter sun. Everyone optimising for their own maximum yield per year is doomed to favour alignment with Summer noons. It's only a 0-sum game _there/then_.

@AdeptVeritatis Nope .. energy companies can go and suck d.. What we need are network operators maintaining the infrastructure for a shared smart grid. So, electricity will in future just come with the cost for the cabling .. and not for the generation.

@AdeptVeritatis @hweimer This is the same question as why the USA import natural gas (for example via pipeline from Canada), if they are one of the biggest natural gas exporters on this planet. They even paid pretty high prices in the past. Real econonics are complex.

@AdeptVeritatis You can watch what will happen in the game: when the sun shines, the price for electricity drops to zero. It doesn't become negative because then it will be more attractive to switch of the electricity generation of the panels. And yes, prices will shoot up at night during winter.
