Smart people, a wealth of knowledge, and the spirit of innovation –
that's what we've been about for more than 30 years.
We are a small, independent and interdisciplinary team of experts, and our main area of expertise is in photovoltaics. We develop projects, advise companies and authorities, and continually produce innovative ideas that we see through to fruition. We do not sell any products, and instead of provide services in form of consulting, planning and project support. We also engage in information, training and lobbying work in the fields of energy efficiency and renewable energies.
The photovoltaic segment has seen massive development in the past 25 years – since TNC was founded – and its future potential is still far from being exhausted. We do our part to make suer this potential is harnessed to the full.
The TNC and Effienergie AG team consists of engineers, architects, energy consultant, and specialists in photovoltaic systems, building renovation and metrology. Together, we have many decades of experience, and we bring a passionate commitment to renewable energies to each new project.
