I already commented on the self-consumtion regulation in draft in Spain, (basically a retroactive measure to stop any development). The reason behind is the excess of fixed system costs; with decreasing energy consumption, power and energy prices increase in a feedback loop. Blocking self-consumption is an attemp to avoid further grid energy consumption decrease.
As in other countries with similar fixed costs, decreasing demand pushes towards higher energy prices, and taxing self-consumption is seen as a regulatory solution. Apparently off-grid is becoming already a cheaper option. As it is not the best solution for the system as a whole, an intermediate solution could be the following: Sigue leyendo →
Solar panel manufacturing has benefited from economies of scale in the race to lower the costs, following an impressive learning curve (see BNEF curve). But will the future bring the cheapest solar panels, being printed where needed from a simple and cheap device?
This is already happening in manufacturing, as described brilliantly by Chris Anderson in Makers. With technology already available for printing solar cells on paper, innovation improving efficiency and durability, is set to revolutionize solar panel manufacturing. Centralized production would be complemented by local micro-manufacturing.
Solar photovoltaics is today the best example/solution for democratization of power generation, as it allows simple and scalable self-consumption. Democratizing also the manufacturing of the panel would take it a step further, boosting solar generation capacity well above the actual double digit yearly growth.
