Munich
Double grid fees on stored electricity were removed from 1 January 2026, so grid charging is fully legitimate. Feed-in at 7.78 c/kWh under EEG 2026.
01 — THE EVIDENCE
Retail price beats sunshine.
Abu Dhabi generates 63% more electricity from the same roof than Munich, and saves the owner 62% less money. The reason is simple: Munich electricity costs 39.6 cents and Abu Dhabi’s costs 7.3. What you save depends far more on what you pay than on how much sun you get.

02 — ALL TWENTY-FIVE LOCATIONS
Ranked honestly, including the ones that disappoint.
Every row is a Signature pavilion with 80 kWh of usable storage and one electric car at 15,000 km a year, priced at €42,800. Rows below are copied from the live capture; remaining cities on the live site keep their notes underneath without invented payback figures.

Gulf paybacks are not quoted on the live site. Doha is shown because the capture listed 22,721 kWh / 3.2 c / €223 / 76% winter. Full 25-row ranking is on the live concept.
City notes
Ranked honestly, including the ones that disappoint.
Yields and published retail tariffs below are from the source city set. We do not invent a payback column for every city.
Berlin
Germany recorded 576 negative-price hours in 2025, 85% of them between 10:00 and 16:00 — precisely when a pavilion can absorb them.
Hamburg
Northern German yields are modest, but the wholesale spread is the widest in Europe. The battery earns year-round regardless of season.
Amsterdam
Net metering ends 1 January 2027 and feed-in charges of EUR 20-50/month already apply, which sharply increases the value of storing rather than exporting.
Copenhagen
High retail prices and a liquid Nord Pool spot market. Winter solar is negligible; the case rests on self-consumption and trading.
Paris
The autoconsommation premium was abolished in June 2026, so the economics now rest on self-consumption and arbitrage rather than subsidy.
Vilnius
In December this roof produces about 149 kWh for the entire month. Filling an 80 kWh battery from sunlight alone would take 17 days. The battery earns from the grid instead.
Warsaw
Rapidly growing midday solar surplus is widening Polish spreads, which favours storage over export.
Milan
High retail prices combined with good yields. Italian spreads are narrower than German but still material.
Nice
Strong yields and wide French spreads make this one of the better Mediterranean cases.
Barcelona
Spain’s contracted-power charge is not avoidable, so only about 62% of the bill can be displaced.
Palma de Mallorca
Island grids place a premium on resilience. Strong export credit under the simplified compensation scheme.
Athens
Greece has both high yields and widening midday surpluses, an unusually favourable combination for storage.
Lisbon
Iberian spreads are narrower than Central European. The case here is led by yield and self-consumption.
Faro
The highest yield in the European set. Even in December this roof produces meaningfully.
Split
Croatia replaced net metering with net billing on 1 January 2026, which materially increases the value of on-site storage.
Nicosia
Cyprus has no accessible household spot market, so no arbitrage value is claimed.
Dubai
There is no honest savings argument. Bought for deep shade, cabin-cool cars, outage resilience and the way it looks. Payback not quoted.
Abu Dhabi
Generates 63% more than Munich from the same roof and saves 62% less. Subsidised tariffs; 27-year payback. Shade and resilience, not ROI.
Riyadh
44-year payback. Bought for architecture, shade and prestige. Import requires SASO and SABER conformity.
Doha
Payback is 64 years and should never be mentioned in a sales conversation. Shade and shelter are the product here.
Los Angeles
High retail rates, excellent yield and time-of-use tariffs that reward evening discharge.
Austin
ERCOT is the most volatile market in this set. Grid resilience is also a genuine local concern.
Phoenix
Exceptional yield with meaningful summer peak pricing. Shade value is substantial where parked cabins exceed 60 degrees.
Miami
Florida has no retail spot exposure, so no arbitrage is claimed. Hurricane resilience; structures require a Notice of Acceptance.
