While the solar hype seems everywhere, I can't stop myself asking few questions.
According to what I heard about it, one of the biggest disadvantage of photovoltaic (PV) is the storage. With most of other electricity "providing" methods, it's possible to manage the quantity of electricity provided and when it's provided (adding coal in the boiler, opening the dam for the turbine, etc.). That means that a private/individual PV provider will not be able to stay self-sufficient along the year and will provide more than it needs at some duration.
The consequence of this technical difference leads, at least on our days, to the obligation of buying electricity by regular providers when it lacks and selling it when it exceeds, assuming that there is no viable storage technologies now, in regards of efficiency and cost (http://euanmearns.com/how-much-battery-storage-does-a-solar-pv-system-need/).
When I read this article, I remembered some newspaper article of this year. It says that the main electricity provider (which is a state/private partnership), will lower the cost for buying PV electricity from privates/individuals (http://www.lechodusolaire.fr/la-suisse-baisse-les-tarifs-dachat-pv-de-7-a-14-lan-prochain/) (http://www.swissolar.ch/fr/services/medias/news/detail/n-n/diskriminierende-tarifstrukturen-es-droht-ein-ausbaustopp-der-photovoltaik/).
According to what precede, I wonder if private/individuals are in position to sell electricity at their convenience and this could lead, unfortunately, to some monopol of the on demand electricity.
