The focus: How to increase your yields in 2025!

Deutschland - The use of photovoltaic systems (PV systems) has increased in recent years because more and more households are trying to meet their energy requirements sustainably. A central aspect of installation is the design and nature of the roof. suedkurier points out that roofs should be in good condition, since a PV system has a lifespan of around 25 years. Inclusive roof surfaces that are aligned to the south and remain as shadow -free are optimal. Alternatives to the southeast or southwest are possible, but offer lower yields.

For a four-person household, a 70 square meter PV system with a nominal output of 13 kilowatts is sufficient to cover the annual electricity requirement. However, it is important to take your own electricity consumption into account, since the production and consumption often do not take place in sync. Especially during the day, more electricity often falls than is currently required, which is why a battery storage is a sensible addition. The prices for battery storage are between 500 and 1,000 euros per kilowatt hour of storage capacity and are freed from VAT.

feed -in tariff and economy

The feed-in tariff is a crucial factor for the economy of a PV system. Currently, the remuneration for powered electricity is around eight cents per kilowatt hour, which makes it more financially attractive to preferably use the self -generated electricity yourself instead of feeding it into the network. According to Balcon power plant24 , the feed -in tariff can be up to 8.1 cents per kWh for partial feeding and up to 13 cents when fully feed -in, the remuneration will regularly decrease by 1 percent every six months. This regulation concerns plants up to 10 kWp, while older systems retain the previous sentences.

Another aspect of the feed-in tariff is the legal regulation in the Renewable Energy Sources Act (EEG), which states that operators of PV systems currently do not receive EEG remuneration for electricity if negative stock exchange flow prices are available. This also applies to new facilities, such as Energy-Expert . However, operators of existing systems can benefit from an increase in remuneration if they opted and adjust their system technology.

balcony power plants - an alternative for tenants

balcony power plants, also known as plug-in solar systems, offer tenants an uncomplicated way to use solar energy. These systems have a maximum alternating current output of 800 watts and are relatively easy to install, but the landlord's consent is required in order to be able to use it. Excess electricity can also be fed into the network, but the remuneration is often lower than with roof systems. It is therefore important to weigh the advantages and disadvantages before installation.

In summary, it can be said that the installation of photovoltaic systems and the use of the feed-in tariff offer an attractive way to meet your own electricity requirements sustainably and at the same time contribute to the energy transition. Whether by optimal roof use or support from battery storage, the perspective for renewable energies remains promising.
