An average 5 kWp system produces around 5,000 kWh of electricity per year. This corresponds to annual savings of 1.5 tonnes of CO2, based on a hypothetical energy mix similar to that of Germany and France. If we assume that the system can cover around 50% of a family’s energy needs, this accounts for an annual saving of 750 kg CO2.

To save costs, solar modules are mostly manufactured in countries where environmental protection plays a less important role and little consideration is given to carbon emissions during production. When it comes to environmental protection during production, Sonnenstromfabrik is one of the solar industry’s role models. Our value chain is optimised for minimal carbon emissions and audited by an external testing institute. We operate our machines predominantly with solar power produced from our own solar modules, and employ state-of-the-art technology. Our plant emits 40% less CO2 than the average German solar company — and over 70% less than international competitors. What’s more, we exclusively use primary materials from CO2-audited manufacturers for our Low Carbon product range.
