Since 2023, the average day-ahead price at 13:00 has fallen from €65 to €21/MWh, while the 21:00 price has risen from €118 to €143/MWh. Hours at zero or negative prices have gone from 108 in 2023 to 941 so far in 2026.

The world installed between 664 and 698 GW of solar PV in 2025, depending on the source, and the European Union 65.1 GW.

A battery is only needed for the energy produced when it is not being used. With the same daily energy and a flat load from 07:00 to 21:00, a fixed panel tilted 30° south has to store 28% of its output in a battery. Vecthor only 14%: half.

From January to October 2026, the average day-ahead price in Spain was €83.5/MWh. But at 13:00 the average was €21/MWh and at 21:00, €143/MWh: the same energy is worth seven times more depending on the hour.

We measured a full day at IMN-CSIC (Madrid): Vecthor produced 50% more per kWp than a fixed 30° south panel, mostly in the morning and the afternoon.

Measured in Madrid: soiling took 0.3% off the performance of Vecthor (V5) and 2.2% off a fixed-tilt system. We explain the optical mechanism: dust on a reflector scatters light, but does not lose it.

kWp or m²? The metric that decides a solar installation’s profitability is NPV. On a 1,500 m² roof in Madrid, VectHor installs less power but delivers the highest net profit per m².

The value of solar energy is not defined only by how much electricity is produced, but also by when it is produced. In electricity markets where prices change hour by hour, generation timing matters almost as much as the total energy output. For commercial and industrial (C&I) self-consumption systems, aligning generation with demand is equally critical, as poor alignment can significantly reduce self-consumption rates. This idea is captured through what is known as the captured price. The captured price represents the average price a solar installation actually earns for its electricity, taking into account when that energy is generated. It

Last May, FutureVoltaics won first place in the Colmeia Accelerator, an initiative promoted by Galp, Fundação Galp, and the Municipality of Matosinhos. The €50,000 award recognized the startup as the project most closely aligned with the program’s mission: implementing and scaling decarbonization initiatives in the Portuguese city. In addition to the financial prize, FutureVoltaics has been granted the opportunity to deploy its innovative photovoltaic system, VECTHOR®, on the rooftop of an educational center in Matosinhos. VECTHOR® stood out from competing solutions thanks to its ability to generate savings compared to conventional systems by optimizing energy capture during periods of higher
