Find Verified Solar Companies Worldwide

PVFirms is an open directory of solar energy companies — covering installers, manufacturers, EPC contractors, distributors, IPPs, R&D firms and consultants across 44 countries in Europe and North America. Browse 7,500+ company profiles, compare services and certifications, and request quotes from local solar professionals. Listings are open, transparent and free to claim.

Why a directory matters: solar accounts for the largest share of new generating capacity added each year in both regions covered here. Procurement, B2B partnerships and end-customer decisions all depend on finding the right counterparty — that's what PVFirms exists to enable.

The Solar Markets We Cover

Solar PV is the fastest-growing energy source in every market in this directory, with rooftop residential, commercial-and-industrial, agri-PV and utility-scale segments all expanding in parallel.

Europe — leaders by installed capacity:

• Germany: ~90 GW installed, the largest European solar market
• Italy: ~30 GW, with strong rooftop adoption driven by Superbonus and Conto Energia history
• Spain: ~28 GW, leading utility-scale build-out across Andalusia and Extremadura
• Netherlands: ~24 GW, highest solar capacity per capita in Europe
• France: ~20 GW, growing through agri-PV and utility tenders
• Poland: ~17 GW, rapid residential adoption via Mój Prąd

SolarPower Europe forecasts annual European installations to exceed 100 GW per year by 2030.

United States — the largest solar market outside China. Our US listings are built from public state interconnection and incentive-programme records, which is why coverage is deepest in California and New York today and is still filling in elsewhere.

Every step of that build-out — site assessment, equipment supply, installation, O&M — runs through the companies listed in this directory.

How to Choose a Solar Provider

• Match the right category — installers, manufacturers and EPCs solve very different problems. Pick the one that fits your project scope before comparing companies.
• Verify certifications — NABCEP, MCS, IEC 61215, Tier-1 BNEF, ISO 9001/14001/45001 depending on the role
• Request multiple quotes — pricing varies 10-30% between providers for the same scope
• Check recent project references — last 2-3 years matter more than legacy portfolio
• Confirm insurance and warranty terms — both product warranty (≥25 years) and warranty insurance against company default
• Read customer reviews — verified PVFirms profiles include reviews; cross-check on independent platforms
