Energy funding in Spain (35 rows, 2020-11-18 to 2025-09-09) shows a wide dispersion in disclosed round sizes: Exus Management Partners’ $308M (2025-07-22, “Series Unknown”) is the only clearly outsized amount in the list, dwarfing the next-largest disclosed rounds such as Opdenergy’s $357M (2022-07-22, “Post-IPO Debt”), Samara’s $10M (2024-06-06, Series A), and several $17M rounds (Nomad Solar Energy $17M on 2024-09-18; bound4blue $17M on 2023-09-06). That contrast is sharper than the smaller end, where multiple disclosed rounds sit under $1M (e.g., QUIXOTIC $1M on 2024-10-08; H2Vector $110K on 2024-09-20; Clever Solar Devices $200K on 2020-11-18).
Temporal clustering is also noticeable: 10 of the 35 rounds fall between 2024-10-07 and 2024-12-20, and city concentration leans toward Madrid/Barcelona/Valencia—Madrid appears in Solfy (2025-09-09, $5M) and Zeleros is Valencia-based (2024-10-07, $3M), while Barcelona-based entries include Submer (2024-12-20, $21M) and Enerside (2022-07-20, $6M). Stages are split between named stages and missing classifications: “Series Unknown” appears in 15 rows, while amounts are explicitly “undisclosed” in 5 rows (including Therminer 2024-10-16 and Ezzing Solar 2023-12-15).

Frequently asked
What’s the largest disclosed round in this Spain energy dataset, and how extreme is it versus the rest?
The largest disclosed amount is Opdenergy’s $357M on 2022-07-22 (“Post-IPO Debt”). The next-largest disclosed rounds shown are far lower (e.g., Exus Management Partners $308M on 2025-07-22, and then multiple single-digit million rounds such as Samara’s $10M on 2024-06-06 and Nomad Solar Energy’s $17M on 2024-09-18).
Do the most recent entries cluster into a short time window?
Yes. Between 2024-10-07 and 2024-12-20 there are 10 entries, including Zeleros ($3M, 2024-10-07), Submer ($21M, 2024-12-20), and Calpech ($620K, 2024-12-19).
Which cities show up repeatedly in this list of Spain energy rounds?
Madrid and Barcelona appear most often, with examples spanning the timeframe: Solfy (Madrid, $5M on 2025-09-09) and SolarYou (Madrid, $510K on 2025-05-03) for Madrid; Submer ($21M, Barcelona on 2024-12-20) and Energiot (Barcelona, undisclosed on 2023-11-28) for Barcelona. Valencia-based rounds include Zeleros (2024-10-07, $3M) and H2Vector is Asturias-based, showing that not all capital-region activity dominates the list.
How much of the dataset is stage-unclear, and how should that affect comparisons?
“Series Unknown” appears in 15 of 35 rows, and “undisclosed” amounts appear in 5 rows (for example, Therminer on 2024-10-16 and Energiot on 2023-11-28). That means many entries can’t be normalized by both stage and disclosed capital, so size comparisons should focus only on rows with explicit dollar amounts.
Are there clear outliers on the small end that could skew deal-size interpretations?
Several rounds are far below the mid-range of $3M–$10M disclosed deals, including H2Vector at $110K (2024-09-20, Seed), Crowmie at $330K (2023-06-20, Pre-Seed), and Clever Solar Devices at $200K (2020-11-18, stage blank). These entries sit alongside much larger disclosed rounds like Opdenergy’s $357M (2022-07-22), so median-based analysis would be more stable than mean-based analysis.
What stage labels dominate among entries that have a disclosed amount?
Named stages are present but less consistent than “Series Unknown.” Examples of named-stage financing with disclosed amounts include Seed (Solfy $5M on 2025-09-09; QUIXOTIC $1M on 2024-10-08), Series A (Samara $10M on 2024-06-06; bound4blue $17M on 2023-09-06), and Debt Financing / Post-IPO Debt (Enerside $6M on 2022-07-20; Opdenergy $357M on 2022-07-22).
Which entries closed at the temporal edges of this page’s date range?
The earliest row is Clever Solar Devices on 2020-11-18 with a disclosed $200K (stage blank). The most recent row is Solfy on 2025-09-09 with a disclosed $5M (Seed), with additional late-2025 entries such as Exus Management Partners on 2025-07-22 at $308M.
