Regarding building volume, only one house has been measured at 216 m3 according to the SIA 416 standard, while 1487 buildings do not follow this measure.

The principle of solar thermal energy is simple : collectors installed on your roof capture solar radiation to heat a heat-transfer fluid. This fluid then transfers the heat to your domestic hot water tank.
Solar thermal collectors usually cover much of summer hot water, providing a free and clean energy source. To ensure optimal performance, it is advisable to check the orientation and tilt of your roof.
A south-facing orientation remains ideal to maximize sunlight throughout the year in Buchs, thereby ensuring better long-term profitability for your energy investment and lower utility costs.
It is often advantageous to pair solar water heating with your existing heating system. For instance, combining collectors with a heat pump needs a sizing study.
This hybrid approach preserves your heat pump during the warmer months while ensuring eco-friendly hot water production. Such synergy optimizes the wear and tear on your main equipment and reduces operational costs.
By carefully planning this integration, you ensure a robust system capable of meeting your household's energy needs in every season while maintaining efficiency in Buchs.
Although amounts vary, it is recommended to regularly check the current cantonal programs in St. Gallen for your project in Buchs. These incentives aim to encourage the energy transition of private buildings.
Remember to check the eligibility criteria before signing any quote, as certain technical or administrative conditions must be met to qualify for these financial supports.
The success of a solar project in Buchs relies on careful preparation. Start by analyzing your household's current hot water consumption to determine the ideal system size.
Always request several quotes from certified companies to compare offers and technologies. Also, ensure your roof structure can support the weight of the solar panels. Finally, use the RenoIndex estimator to gain a clear view of the expected costs.
A methodical approach helps you avoid budget surprises and ensures a long-lasting installation that adds value to your home while meeting current standards in the canton of St. Gallen.
