Delivering Ultra-Low-Energy affordable homes for Wales

Western Solar

Ty Solar Home

Western Solar has pioneered the use of solar energy for housing in West Wales. We built the first solar park in Wales – now generating energy to power 500 homes. We designed and built Tŷ Solar® – a prototype solar house that has a superior A++ energy rating and functions both as a home and a power station. We have gone on to build four solar hamlets of 30 affordable homes. Each one has been hand crafted by our workforce to the highest standards and which has delighted people who have lived in them.

Energy Efficiency

Energy efficiency in housing is key to our design. Good energy efficiency not only saves us money but also saves the planet by reducing carbon emissions. Our homes are south facing to maximise the energy from the sun with large windows giving us 80% of our space heating. We achieve the highest energy efficiency ratings with no compromises on insulation and the use of photo voltaic solar panels and intelligent electric heaters. Our Tesla Powerwall systems help you monitor your energy consumption.

Canopies for summer shading


One of the distinctive features of a Ty Solar home is the sense of well being when you enter one. Maximising the use of natural light enhancing that sense. We don’t use oil-based paints or adhesives thereby reducing the carcinogens in the rooms.

Loving the Earth

The construction industry is responsible for over 40% of global emissions of CO2. All Ty Solar Homes have a low embodied carbon content, being made of timber which is locally sourced from sustainable woodlands. In addition, each home has its own mini power station producing carbon-free energy at the point of consumption. We estimate that a 4-bed Ty Solar home avoids up to 254 metric tonnes of carbon equivalent to the environmental benefit of planting 200,000 trees for the 1000 homes we plan to build.
