Photovoltaics – the Key to the Energy Transition

Effective climate protection and the implementation of agreed national and international climate targets require a significantly accelerated expansion of renewable energies. According to the German government’s target, the share of renewable energies is expected to increase to 65 percent of electricity consumption by 2030. At the same time, the demand for electricity is likely to increase significantly due to new cross-sector technologies such as electromobility and Power-t-X systems.

Over the past two decades, photovoltaics has developed from an expensive space technology to the most inexpensive and popular form of energy with the highest growth rates and growth potential worldwide. The German Solar Association and its predecessor associations have played a major role in ensuring that it now plays an indispensable key role in achieving climate targets. The solar industry is working together with the German Solar Association to leverage all available PV market potential to the necessary extent and at the necessary pace: From small rooftop systems to large open space systems; from full feed-in to innovative neighborhood and own consumption concepts.

With this goal in mind, the German Solar Association enters into dialogue with political decision-makers, business representatives, the media and the public. In close exchange with its members, it develops positions on concrete legislative initiatives, standardization processes and current issues of energy policy in order to ensure attractive investment conditions and to remove market barriers with united efforts.

Study: Energy Transition in the Context of the Nuclear and Coal Phase-out

The joint study by German Solar Association, EuPD Research and The Smarter E Europe — analyzes the development of the German electricity market up to the year 2040 and draws a realistic picture of the future, both of the development of future electricity generation and of the expected electricity consumption. A core result of the analysis carried out in the study is the significant increase in net electricity consumption in Germany from approx. 530 TWh today to approx. 880 TWh in 2040, partly due to new electricity consumers such as e-mobility and Power-t-X applications. The study shows that in order to cover the growing electricity consumption and to compensate for the phase-out of coal and nuclear power, the installed PV capacity must approximately triple compared to 162 GW in 2030 and increase to 252 GW by 2040. In order to achieve this, an increase in the expansion of photovoltaic generation capacity to more than 10 GW/year is necessary in the coming years.

Tenant Flow and Neighborhood Concepts

The use of solar power is becoming more and more interesting in the big cities. As a result, residents of apartment buildings can finally benefit from cheap solar power. Tenant electricity and neighborhood supply combine consumer demands for cheap and clean energy with new opportunities for the energy and housing industry. By entering into tenant electricity and neighborhood supply solutions, the building services are being modernized, thereby reducing an investment backlog. Entirely new options are opening up, for example, for energy management, recording consumption data, or entering the field of electromobility. Further information on the topic of tenant electricity can be found at sonneteilen.de (German)

Combining Electromobility and PV

More and more entrepreneurs in Germany want to make an active contribution to climate protection and are investing in their own photovoltaic systems, in the electrification of their own vehicle fleet and in e-filling stations for their own staff. A combination of a photovoltaic system, solar power storage, and e-vehicles also makes sense for business management reasons. This is because solar power from the company’s own solar power system is usually less expensive for commercial enterprises than electricity from the energy supplier. In addition, companies can optimise their load profiles and reduce costs by avoiding peak loads. The trade guide “Combining photovoltaics and electromobility sensibly”, developed by the German Solar Association in the EU-funded project PV-Prosumers4Grid, points the way to practical implementation.

Grid Integration and Feed-in Management

The feed-in management of PV systems is playing an increasingly important role due to the growing share of solar power in the grid. This creates new challenges and requirements for solar power operators, such as the technical specifications of Section 9 of the German Renewable Energy Sources Act (EEG). The specific requirements to be met depend on the size of the plant. Plants with an installed capacity of more than 100 kWp must have technical devices that enable the grid operator to call up the feed-in power at any time and to reduce it remotely in the event of grid overload. For plants with an installed capacity of up to 100 kWp, the equipment with technical devices is sufficient for a remote-controlled reduction of the feed-in power in case of grid overload by the grid operator. For plants with an installed capacity of up to 30 kWp, the plant operator can alternatively limit the maximum active power feed-in to 70 percent of the installed capacity from the outset. PV systems with an installed capacity of 100 kWp or less may only be regulated at a lower level than other renewable energy and CHP systems.

New Business Models

Photovoltaics has made great strides towards competitiveness in recent years. More and more private households and electricity consumers in trade, commerce, and industry, but also increasingly municipal utilities, energy cooperatives, and local housing associations are using solar electricity for their own consumption or within the framework of new direct marketing models. These new business models—above all own consumption, electricity supply, plant leasing, operator and business management models—are increasingly becoming the basis for the economic operation of PV plants. They support the PV market, especially where the sharp drop in feed-in tariffs under the German Renewable Energy Sources Act (EEG) is no longer sufficient to refinance on its own. In this sense, they are gradually taking photovoltaics out of the EEG’s support system.

The German Solar Association is committed to the solar industry in Germany and internationally to the development of new business models for solar power. On the one hand, the focus is on the design of suitable legal and administrative framework conditions. At the same time, there is still considerable uncertainty among many market players about the potential but also about how to open up sales and the concrete implementation of such new business models. This concerns questions of financing, plant and metering concepts, the regulatory framework of the energy industry, and the concrete contractual relationships between plant operators, land owners, investors, and electricity consumers.
