Balcony power plant 800 watts is finally available
Introduction:
Balcony power plant 800 watts is finally here! After 600 watt balcony power plants had been popular for several years, the 800 watt limit was finally lifted in January 2024. This was based on a proposal from the Association for Electrical Engineering, Electronics and Information Technology (VDE), which was adopted by the German government.
What are the changes to the 800-watt balcony power plant complete set?
The balcony power plant is made up of solar modules, micro-inverters, brackets and cables and can be integrated directly into the home network. The following products must be replaced in the kit:
- Solar modules: Individual modules with an output of 400 watts or more are required.
- Microinverter: A microinverter with an output of 800 watts or more is necessary. Microinverters less than 800 watts cannot handle the amount of energy produced.
Sunnex has completely discontinued the 600-watt balcony power plant. Our kits now include an 850 watt solar panel and an 800 watt micro inverter. You can buy with confidence without having to upgrade when you receive delivery.
How much electricity can an 800 watt balcony power plant generate?
To calculate the electricity production of a balcony power plant with a peak output of 800 watts (in kilowatt hours), several factors must be taken into account, including location, orientation of components, season, solar radiation, possible shades and angle of inclination.
A solar system produces approximately 1.000 kWh of electricity per year per installed 1 kWp (kilowatt peak) photovoltaic output. In northern parts of Germany the radiation is around 800-900 kWh, while in southern regions it is 1.000-1.200 kWh reached.
The estimated annual electricity production can be calculated as follows:
- At least: 0.8 kW * 800 kWh/kWp = 640 kWh
- Maximum: 0.8 kW * 1000 kWh/kWp = 800 kWh
These values are estimates and do not necessarily represent actual electricity production. Please note that actual production may vary throughout the year due to seasonal fluctuations. The maximum electricity production is achieved in summer.
How much money can a balcony power plant with 800 watts save per year?
Based on an estimated electricity production of 800 kWh, with an electricity price of 0.5 euros per kWh, you can save a maximum of 400 euros per year. With falling prices for balcony power plant kits, the payback period can be shortened to around 3-4 years.
Does a balcony power plant with 800 watts have to be registered?
Yes, a balcony power plant with 800 watts must also be registered, just like the 600 watt balcony power plant before.
In addition, devices with an output of more than 800 watts must still be installed and registered by certified electricians. This situation could change in the future.
Does storing an 800-watt balcony power plant make sense?
Unfortunately, it is not worth storing the electricity generated by a balcony power plant. The investment in batteries will likely take several decades to pay off. Instead, if you have a lot of solar panels on the roof, you could consider our 10KW three-phase high voltage inverters and 10KWH high voltage storage batteries.
These batteries can store more energy and provide longer support time and more applications.
Conclusion:
With the introduction of 800-watt balcony power plants, decentralized energy generation reaches a new milestone. The higher output not only enables more efficient use of solar energy, but also opens doors for wider acceptance of renewable energy in the home. Balcony owners can now make a greater contribution to sustainable energy with optimized systems.
