From sunlight to long-term revenue
Solar is now the most affordable energy source in Europe — but only when designed, financed and operated by true specialists. VoltWatt turns every hour of sunshine into stable, decades-long revenue and tangible savings on your energy bill.
Maximum savings, no upfront cost
VoltWatt finances, builds and operates your solar plant. Earn a guaranteed long-term rent for your roof, land or parking — or buy back your own green electricity through a PPA priced well below grid tariffs. Zero investment from you.
Dispatchable & Bankable
Co-located storage, AI-driven forecasting and corporate PPAs convert intermittent solar into 24/7 firm green energy that lenders, off-takers and grid operators can rely on.
Land-Positive Development
Agrivoltaics, floating PV and brownfield siting make solar the only utility-scale renewable that adds value to the land it occupies — biodiversity, agriculture, water savings.

Frequently Asked Questions
Everything you need to know about VoltWatt's solar solutions — for roofs, land, parkings, agriculture and industry.
What types of solar energy systems does VoltWatt develop?
VoltWatt develops utility-scale photovoltaic (PV) power plants, rooftop solar installations, and floating solar systems. Our projects range from 1 MW community installations to 200+ MW utility-scale farms across France, Germany, Spain, and Italy, using the latest bifacial and heterojunction cell technologies for maximum energy yield.
What is the average energy production of a VoltWatt solar farm?
A typical VoltWatt solar farm produces between 1,200 and 1,800 MWh per MW installed capacity annually, depending on location and technology. Our optimized tracker systems and bifacial panels can increase yield by 15-25% compared to fixed-tilt installations.
How does VoltWatt ensure the environmental sustainability of its solar projects?
VoltWatt conducts comprehensive environmental impact assessments for every project, implements biodiversity plans including pollinator-friendly ground cover, uses recyclable panel materials, and partners with local ecological organizations. We also integrate agrivoltaic solutions that allow continued agricultural use of land beneath solar panels.
What is the lifespan of a VoltWatt solar installation?
VoltWatt solar installations are designed for a minimum 30-year operational lifespan with performance guarantees. Our panels maintain over 85% of their initial capacity after 25 years, and we provide full asset management services including monitoring, maintenance, and end-of-life recycling programs.
In which European countries does VoltWatt operate solar projects?
VoltWatt currently operates solar projects in France, Germany, Spain, and Italy, with a combined portfolio exceeding 2.1 GW of installed and pipeline capacity. We are actively expanding into additional European markets to support the EU's renewable energy targets for 2030.
