Technical deep-dives, industry analysis, and practical guidance for electrical engineers and renewable energy professionals.
Select a country, enter a city, and adjust system size to explore solar yield estimates powered by PVGIS 5.3 — the EU's official photovoltaic database.
A technical analysis of the most common cable sizing errors in EU residential projects, and how automated validation eliminates the three failure modes that account for 80% of non-compliances.
As battery costs decline and chemistry options expand, choosing the right storage technology impacts system ROI over a 25-year horizon. We break down the trade-offs with real data from 8 EU markets.
Net metering reform is reshaping the economics of Dutch residential solar. We model the financial impact across system sizes and explore how battery storage changes the equation.
IEC correction factors are multiplicative — and the interactions between them are poorly understood. We walk through real scenarios showing how combined derating affects cable selection.
A mid-sized Dutch installer shares how automating engineering calculations allowed them to double project throughput without adding engineering headcount.
How large language models combined with structured engineering data are creating a new category of analysis tools — and what this means for the future of power systems engineering.
🔄 Insights are published regularly. Future integration with an automated content pipeline will enable scheduled publishing at set intervals.
Quasar Energy was founded to bridge the gap between enterprise engineering software and the day-to-day needs of electrical and solar installers across Europe.
Our team combines deep domain expertise in electrical power systems and renewable generation with modern AI capabilities. We believe that professional-grade engineering calculations should be accessible, affordable, and fast — without compromising on accuracy or standards compliance.
