How does a solar power plant work?The photovoltaic cells in photovoltaic modules generate direct current from solar energy. In order to use the generated direct current in the home, an inverter was inserted. The inverter converts the generated direct current into standard household alternating current. Then, the green electricity generated in this way is fed into the house or apartment network through ordinary sockets. Then the electrical appliances directly consume the generated electricity. As a result, the meter rotates more slowly or even stops.2. Can I use a solar power plant outside the balcony?In theory, yes, as long as there is sufficient sunlight and a socket within arrive of the accompanying cable at the installation site. The manufacturer's installation method must be followed for fixing. In other installation locations, such as garage roofs or wall mounted installations, corresponding building rules and standards must be followed. Please note that in Austria, any location changes must be promptly notified to the distribution system operator. Demolition of solar power plants and bringing them into one's own apartment is not prohibited.3. If there is a power outage, can I use a solar power plant to power my apartment?No, for safety reasons, the equipment can only supply power to the grid when it is powered on. If the power grid fails, our solar power plant will be in a protected state and not output electricity to ensure the safety of electricity consumption.4. The solar panel cannot be folded.
