The energy self-sufficient prefab home was built on the campus of the TU Darmstadt and transported to the USA after completion. The house is a wooden lightweight construction with low heat storage mass compared to massive new buildings.
The solar power off-the-grid prefab home "Solar House" designed by students of the TU Darmstadt has won the international competition "Solar Decathlon 2007" for the most attractive and energy-efficient solar house. The energy self-sufficient prefab home was built on the campus of the TU Darmstadt and transported to the USA after completion.
In order to meet the transport requirements, the solar power off-the-grid prefab home is constructed in a modern timber construction. The modular design is a combination of timber frame construction with sandwich and box elements. The load case transport was taken up by steel components and considered from the outset and aesthetically integrated.
The solar power generated is fed via an inverter into the public grid of the electricity supplier. The Renewable Energy Sources Act (EEG) guarantees the operator of a photovoltaic system the acceptance and payment of the electricity by the locally responsible energy supply company.
Also referred to as an autonomous backyard home, it produces zero emissions and avoids the irresponsible depletion of natural resources, seeking to improve people’s health and wellbeing. In an effort to deliver these self-powered homes at a massive scale, it was necessary to come up with an innovative modular construction system.
General functional description of the system This system is intended to meet the energy requirements, thermal and electrical, of a particular home type. The home type is made up of detached independent house, with a covered area of 120 m2 on two floors (60 m2 surface in the plan), inhabited by 4 people and located in the province of Cagliari.

Building Integrated Photovoltaics: Is BIPV Best for Solar Electricity?
Like all forms of photovoltaic, these systems generate low voltage electricity from sunlight. The integrated bit is the key. Rather than building a roof and then installing solar panels on top of it, with BIPV the modules are part of the roof covering. So, they''re keeping the building dry as well as generating power. BIPV basics
