Great, reliable company. We had our PV system including storage installed and are 100% satisfied. Very punctual, clean, helpful with questions and always available! Thank you 🙏🏻
Although the execution of the well-planned project proved somewhat challenging, the PV system was completed to our complete satisfaction thanks to a dedicated and well-coordinated team. Efficiency Project handled all the necessary paperwork and registrations and kept me informed of the progress at all times.
Excellent advice and professional implementation! Just two days after my inquiry, I received a no-obligation site visit, including a drone flight – incredibly fast and professional! All the advantages and disadvantages of the system were explained to me clearly and understandably. - Top-quality workmanship - Expert and clean installation - All deadlines met precisely - Priced approximately 25% lower than other offers - Complete handling of subsidies by Efficiency Projects Always available, always friendly – my consultant answered every question clearly and patiently. The installation was quick and without any damage. Commissioning the system was also incredibly easy – everything was well explained, no prior technical knowledge required. I would also like to particularly commend the advice I received regarding an energy community I was planning – very competent and future-oriented. Conclusion: I feel I am in excellent hands with Efficiency Projects GmbH – everything was perfect from the initial consultation to the completed system. Highly recommended!
Professional, affordable offer and quick processing. Our system is sized at 3.64 kWp and has been running smoothly for over a week now. A pleasing initial result: as a two-person household, we hardly had to draw any electricity from the grid last week (WK15, Vienna). It's fun to monitor the current power consumption online and hunt down unnecessary energy guzzlers in the house. We'll see if it works well in winter too; but we're optimistic about the solar future.
A highly professional installer of photovoltaic (PV) systems, acting as a general contractor from planning and development to handling subsidies! Top-notch customer focus and speed – quickly greening my home! The entire team responded to inquiries and questions with exceptionally fast response times. The quality is excellent, and the price is fair for what's offered. I would absolutely recommend them.
