More than 15,000 units:
Balcony PV systems already more powerful than the Traun power plant
Quick to install, relatively inexpensive, and no red tape—the selling points for mini-PV systems are compelling. And in Upper Austria, there are now so many that they outperform the Traun Power Plant in Gmunden—at least when the sun is shining.
Kronen Zeitung als bevorzugte Google-Quelle hinzufügen “Reaching the 15,000-unit milestone for balcony solar systems shows just how many customers are taking advantage of the opportunity to cover part of their own electricity needs. They offer a hassle-free way to get started with generating your own electricity,” says Michael Haselauer, managing director of Netz OÖ, expressing his delight at the high demand. Since Netz OÖ doesn’t serve all of Upper Austria, it’s safe to assume that nearly 19,000 systems are in operation statewide.
Use it yourself, or you won’t get paid
Balcony power plants are generally limited to 800 watts of output, and anyone who generates more electricity than they consume feeds it into the public grid for free. For this reason, many users of these mini-PV systems have installed a small storage unit to be able to use the excess energy themselves. Such balcony power plants, complete with a 2.24 kWh storage unit, are available starting at around 850 euros. Anyone who purchases one simply needs to register it with the grid operator—no permit is required—and can easily connect it to the grid via a standard outlet at home.
Water Can’t Beat the Sun in the Long Run
Taken together, these small PV systems generate a substantial amount of power. Netz OÖ has calculated that their output already exceeds that of the Traun Power Plant in Gmunden—but only when the sun is shining. As a result, there is still a significant difference when calculated over the course of a year. For example, the 15,000 balcony power plants generate a maximum of 13 million kilowatt-hours based on an estimated 1,100 full-load hours of sunshine, while the Traun power plant generates around 50 million.
