You’re enrolled into our VPP - You will receive your personal Besst community account for earning virtual shares
Now You can earn virtual shares based on your participation - You receive your first shares directly to your community account
Besst operates the VPP and generates profits for our users
This is more than clean energy. It’s a shared economy of power – where homeowners, not just utilities, benefit from the energy transition.

The BESST Community Model
For decades, households have lived inside an energy system they don’t control. Electricity is something people depend on, but rarely influence. Prices move without warning, rules shift overnight, outages happen – and when they do, people are simply expected to adapt. The BESST community model flips that dynamic. It gives

Why solar panels + ESS will give you maximum ROI
Most households with rooftop solar use only a small share of the electricity they generate. In a typical European home, self-consumption averages around 25–35%.

These devices typically include home batteries, rooftop solar systems. Centralised software coordinates their operation, allowing the aggregated system to respond to grid needs in real time.

Midday prices collapse during solar peaks. Grid curtailment limits usable generation. A battery offsets these losses by keeping energy inside the home, stabilising consumption, and

Stop Donating Your Solar Power to the Grid
