Summary

The speaker, Christin von Perbandt, presents her practical experience with direct marketing of solar energy at the Victron Techhub 2026. She explains the concept of directing selling PV electricity on the exchange instead of using fixed feed-in tariffs. She outlines four ways to register a PV system: fixed feed-in tariff, subsidized direct marketing, other direct marketing, and tenant electricity. For her 12 kWp system with 77 kWh battery storage, she opted for subsidized direct marketing, receiving a market premium on top of the exchange price. She details technical requirements, including smart meters for 15-minute measurements and a control interface for systems above 25 kWp. She shows charts of market values and her own earnings, emphasizing higher revenues by shifting feed-in to high-price periods. She also discusses costs, such as monthly fees of 30 EUR and 3% of revenues, and concludes that the approach is economically beneficial despite complexities. The talk includes audience questions on battery lifespan and technical integration, and touches on net-serving behavior.

Critical Evaluation

Value of the Information & Strength of the Argument

The value lies in the practical, real-world insights into a niche aspect of solar energy economics. The speaker provides concrete numbers on market prices, her own feed-in tariffs, and storage strategies, making the information actionable for other PV owners considering direct marketing. The argumentation is based on her personal experience, which strengthens credibility but also limits generalizability. She logically connects regulatory structures (EEG) to technical requirements and economic outcomes, creating a coherent narrative. However, the lack of broader data or comparison with other systems reduces the scientific robustness.

Scientific Rigor, Source Quality, Title Accuracy

The talk is not a formal scientific study but a practitioner’s account. The speaker cites specific regulations (EEG 2020, paragraph 51a) and market values, which adds factual grounding. However, she does not provide external references or citations for her claims, and the information is largely anecdotal. No formal sources are mentioned in the video description aside from a Discord link for community discussion. The title accurately matches the content, focusing on direct marketing in practice. The technical explanations are plausible and align with common knowledge in the solar industry, though the lack of verifiable references lowers the scientific rigor.

Contribution & Novelties

The main contribution is a first-hand account of direct PV marketing from a small-scale system owner, detailing both technical setup and financial outcomes. It offers practical guidance for similar projects, including battery sizing, market timing, and fee structures. The talk bridges the gap between theoretical market mechanisms and everyday implementation.

Pour aller plus loin :

German Renewable Energy Sources Act (EEG) — Legal framework governing feed-in tariffs and direct marketing.
Electricity market — Explanation of spot markets, negative prices, and market premiums.
Battery energy storage system — Technology for storing PV energy and shifting feed-in to high-price periods.
Smart meter — Essential for real-time measurement and control in direct marketing.
