Hungary's Odooproject prefab home produces twice the amount of energy it consumes | Sustain Our Earth |

The prominent south-facing wall features a considerably large surface area that is entirely fitted with photovoltaic panels. During the summer months when the sun is high, solar energy is produced by the roof panels, while during the cooler months when the sun is lower, energy is produced by the south-facing wall. “Ultimately, owing to this system, the house generates twice as much energy in Hungarian conditions and three times as much in Madrid as the house itself spends,” the Odooproject team states. “This amount is able to serve two other house’s needs, or provide a 70-kilometer (43.5-mile) long travel distance – daily – for an electric car.”
