The 10 Best Solar Panel Installers in Frankfurt

Frosch Solar suits homeowners south of Frankfurt who want a fixed price before work begins. The Dreieich company plans and installs photovoltaic systems with battery storage and wallboxes for homes as well as commercial and industrial buildings. Its offers come with a fixed-price guarantee and advertise zero VAT, in line with the zero rate for small home systems. After commissioning, the same team stays on for service, storage maintenance and panel cleaning, so one firm looks after the system over the years.

Solarengel is a good fit for homeowners who value firm deadlines and clear billing. The Hattersheim company plans and installs photovoltaic systems for households and businesses, working with brands such as Trina Solar and Solarwatt. Quotes are fixed-price, the invoice follows only once the agreed work is delivered, and the firm carries the risk of unplanned extra work. Its stated target is commissioning within 12 weeks of the order, with part of the customer's electricity bill covered if it runs late.

Terra Energys fits households that want solar, storage, heat pump and wallbox bought as one bundle. Its Terra365 package combines these with an energy management system and a dynamic electricity tariff called Power365. The Meisterbetrieb, with its address in Offenbach, works across the Rhine-Main area from Frankfurt and Bad Homburg to Darmstadt and Hanau. Offers are fixed-price, and the company aims to finish projects within ten working days of approval, listing 30-year warranties on modules.

EWH Solar is the choice for homeowners who prefer a published package price to an open-ended quote. Four bundles, from 4.5 kW with a 6.4 kWh battery up to 19 kW with 19 kWh of storage, include modules, battery, installation and grid registration. The Eschborn company works with EcoFlow, KSTAR and Sigenergy batteries and bifacial double-glass modules. Because the bundles are listed online, they are easy to compare with other offers before the free first consultation.

NOVONTECH suits clients who want an electrical master business to handle the whole installation. The company plans and installs photovoltaics, battery storage, wallboxes and heat pumps for private houses and commercial premises. Its Eschborn office covers Hessen, with further sites in Saarland and Rhineland-Palatinate. After a free first consultation and a site visit, its own technicians install the system, and the company states that all work is carried out to standard and fully insured.

Taunus Solarenergie appeals to owners who want the whole job done by employees rather than subcontractors. The Steinbach company has installed photovoltaic systems across the Rhine-Main area since 2009 and states that it has completed more than 2,000 of them. Engineers, electricians and installers are employed directly, and the firm takes care of permits and registrations. Storage, wallboxes, heat pumps and air conditioning are offered as well, so later upgrades can stay with the same team.

Lehmann Energie stands out for the survey work it does before a quote is written. The Offenbach firm measures each roof by drone, builds a 3D model and itemises every component in the offer. It starts only once the grid operator has approved the connection, and a crew of two to four usually finishes within a week. Projects range from single-family homes to a condominium roof and commercial systems above 100 kWp, and the firm also inspects, maintains and repairs systems.

ENVIRIA is aimed squarely at companies rather than homeowners. The Frankfurt firm develops solar systems for commercial and industrial roofs from about 1,500 square metres, along with battery storage, EV charging and energy management. Clients can buy the system, rent it or lease out their roof, and ENVIRIA covers financing, planning, installation, operation and maintenance. That makes it a fit for logistics, retail and property owners planning large rooftop systems without tying up their own capital.

enerix Frankfurt suits households that want PV, battery, heat pump and wallbox linked into one managed system. The Eschborn branch of the nationwide enerix network is run by engineer Matthias Kögel and covers Frankfurt plus towns such as Bad Homburg, Oberursel, Bad Vilbel and Friedberg. Its advisers are TÜV-certified, and the first consultation at home is free and non-binding. One contact person stays with the project from planning to installation, which keeps permits and the grid connection in one pair of hands.

Knight Solar is worth a call for owners who want a small, engineer-led firm. Led by Diplom-Ingenieur Farid Eghtedari, the company installs photovoltaic systems with or without battery storage, from small home systems to custom commercial projects. It works within about 80 kilometres of Offenbach, which takes in Frankfurt and the wider Rhine-Main area. A free on-site consultation comes first, and full-black modules are available for owners who care about how the roof looks.
