Solar space heating – Solar-powered air heaters and rock bed thermal storage to heat homes \r\n.
Developed in 2010 in Germany, Simply Solar provides a solution to Affordable & clean energy, Sustainable cities & communities, – in line with sustainable development goals for the future.
- Air is used as heat transfer medium – no anti-freezing agent, no pressure at stagnation temperature in summer, no corrosion). Small leakages do not affect performance. No electronics used.
- Modularity allows adaptation to many consumer needs from collector sizes of 2 m² to 120 m².
- Easy to transport and assemble, due to sturdy modular design at low weight. Glass is placed during installation.
- Rocks are available in many regions at low cost which permitting big storage heat capacity, so the heat demand can even be covered for 1-2 days without sun.
- Minimal user operation required. Just a on/off switch for the automatic fan operation in heating season.
- Depending on the region, the system saves up to 90% of the conventional fuel used for space heating, translating to 370 USD per home in Ladakh and Kargil.
- Initial investment is paid off in 4-5 years.
- Locally sourced and produced materials allow for easy maintenance and job creation in the region.
