Photovoltaic

What Photovoltaic does

Photovoltaic is a Greek technical and commercial company founded in 1995 by Marios Sigalas, operating as a Single Member Private Company (ΜΟΝΟΠΡΟΣΩΠΗ ΙΚΕ) headquartered at Elanikou 20, Athens. The company specializes in renewable energy systems with a primary focus on photovoltaic (PV) solutions, both stand-alone (off-grid) and grid-connected (on-grid/net-metering), with optional battery storage integration. Over more than 25 years it has built a reference portfolio of installations across Greek public infrastructure — including Athens International Airport (El. Venizelos), OASA and OASTH bus stops, the Centre for Renewable Energy Sources & Saving (CRES), the Skinakas Observatory, a Mount Athos installation, and Greek island projects on Kira Panagia (Alonissos) and Amorgos — and supported implementation of Greece's first Net Metering framework under Law 4254/2014.

The business operates two reinforcing revenue streams. First, an e-commerce storefront at photovoltaic.gr sells individual PV components — solar panels (50W–415W models from Solar Fabrik and own-brand), charge controllers (Steca, MPPT and non-MPPT), inverters and hybrid inverter-chargers (Steca-Studer XTH/XTM/XTS, Outback FXR/VFXR, Cotek SP series, Victron), deep-cycle batteries (Rolls AGM/Gel/Series 4000/5000, Enersys OPzS), aluminum mounting systems, small wind generators, and self-contained solar lighting — priced individually from €35.96 to over €10,000 inclusive of Greek 24% VAT, with free shipping within Greece. Second, the company delivers installation and engineering services (feasibility study, system design, installation, after-sales maintenance) on a project-quoted basis for residential, commercial, agricultural, government, and island/remote-grid customers, plus solar park development for investors and communities. Authorized dealer/service center relationships with Rolls, Studer, Steca, Solar Fabrik, and Outback Power anchor the catalog, and complementary brand partnerships (Victron, Cotek, Enersys, Gisman) round out the range.

The company is founder-owned and operated with no external investment or venture capital involvement. It maintains a Greek and English bilingual website, distributes a bilingual blog covering Greek energy legislation (net-metering, "Save Energy 2025") and exhibition news, and participates regularly in VerdeTec, Intersolar Europe, IndustryTec, and OFF-GRID Expo & Conference. International shipping to EU and non-EU countries is available through the storefront, while installation sales remain domestic and project-driven.

Core offering

Photovoltaic manufactures, trades, and installs autonomous (off-grid) photovoltaic systems, grid-connected (net-metering) photovoltaic systems, and photovoltaic solar parks. Through its e-commerce platform photovoltaic.gr, it retails individual PV components — solar panels, charge controllers, inverters, batteries, mounting structures, wind generators, and standalone lighting — and delivers turnkey engineering, installation, and maintenance services across Greece. The company is a single-member IKE (private company) founded in 1995, headquartered in Athens.

Product overview

Photovoltaic is a Greek technical and commercial company founded in 1995, specializing in renewable energy systems with over 25 years of experience. The company operates primarily as an e-commerce platform offering a comprehensive portfolio of solar energy products including photovoltaic panels (from brands like Photovoltaic own-brand, Solar Fabrik), charge controllers (MPPT and non-MPPT types), inverters (standalone, grid-connected, and hybrid from Steca, Outback, Studer, Victron, Cotek), and deep cycle batteries (Rolls, Enersys). The product line also includes mounting systems, wind generators, and self-contained lighting. Beyond product sales, the company provides installation and integration services encompassing stand-alone PV systems for off-grid applications, on-grid systems with net-metering capability, and large-scale solar park development. The portfolio spans residential, commercial, and utility-scale applications across Greece, supported by partnerships with international manufacturers.

Direct peers

• Victron Energy: Dutch manufacturer of inverters, chargers, and off-grid/standalone power systems. Highly comparable to Photovoltaic's core off-grid/stand-alone PV specialization, though Victron is a global product manufacturer rather than an installer/retailer.
• IBC Solar: German solar EPC contractor and PV component distributor serving residential, commercial, and utility-scale markets. Directly comparable hybrid business model (distribution + installation) to Photovoltaic, but at much larger scale and broader European footprint.
• Krannich Solar: European solar wholesaler and PV system distributor with operations across multiple countries. Comparable distribution business model selling panels, inverters, and mounting systems, but focused on B2B installer channel rather than end consumers.
• Memodo: German online retailer and wholesaler of solar PV components including inverters, modules, and storage. Comparable e-commerce-led distribution model to Photovoltaic.gr, though serving DACH markets.
• Studer Innotec: Swiss manufacturer of inverter-chargers and power conversion equipment for off-grid and grid-tied applications. Directly comparable to Photovoltaic's focus on stand-alone and hybrid PV systems, and an actual supplier to Photovoltaic.gr.

Broad incumbents

• Solarwatt: Established German solar panel manufacturer and turnkey PV system provider for residential and commercial customers. Comparable in offering complete solar solutions but operates at significantly larger scale with own-brand glass-glass panels.
• Fronius International: Austrian manufacturer of solar inverters, battery storage, and energy management systems. Comparable as a supplier of inverter/charger technology to the Greek PV market and as an indirect competitor in on-grid solar solutions.
• Enphase Energy: US-based global leader in microinverter-based solar and storage systems. Comparable as an inverter technology provider in the residential and commercial solar market, though competing at a very different scale and product category.
• Tesla Energy: Solar roof, solar panel, and Powerwall battery storage business of Tesla. Comparable in delivering integrated PV + storage solutions for residential customers, but operating as a global broad incumbent with much larger scale.
• SolarEdge Technologies: Israeli-headquartered global provider of DC-optimized solar inverters and power optimizers. Comparable as a supplier of inverter technology for residential and commercial PV installations, competing indirectly with the inverter brands Photovoltaic distributes.
