The 10 Best Solar Panel Installers in Berlin

solarpol suits buyers who like to know the rough cost before anyone climbs onto the roof, since the Steglitz firm publishes guide prices for typical system sizes and batteries. Offers are drawn up after a phone needs analysis, and the site inspection follows once the offer is accepted. Installation is scheduled within eight weeks of signing, with the grid operator changing the meter a few weeks later. Managing partner Felix Polster is also a TÜV-certified photovoltaic appraiser.

GFK Solar suits homeowners who want a short, predictable project: installation usually takes one to three working days and the whole process about three to four weeks. The master electrician business in Hönow, on Berlin's eastern edge, mounts systems only with its own permanent staff and chooses brands independently of manufacturers. There is no down payment, as the invoice follows commissioning. The office also opens on Saturdays, which helps if you work during the week.

Its strength lies in doing everything with its own staff: SolarX sends in-house teams for the roof, the electrics and the heating, without subcontractors. From its base in Reinickendorf it combines solar, batteries and wallboxes with heat pumps under its sister brand HeatX. A fixed-price quote usually follows the site visit within three to seven days, and installation takes one to two days. Payment is due only after commissioning, which keeps the risk on the installer's side.

Solaro PV suits homeowners who want a wide choice of hardware, from Tesla and BYD batteries to Enphase and SolarEdge systems. The team in Reinickendorf includes engineers, solar fitters and master electricians, and it handles grid operator registration and documentation at commissioning. An online configurator gives a first idea of the system, and the initial consultation and financing advice are free. Ongoing monitoring after installation helps catch output losses early.

Lauckner suits owners who want the panels to replace the roof covering rather than sit on top of it. The master craftsman business in Reinickendorf builds in-roof systems, in which the modules take the place of the tiles, as well as standard rooftop, carport and façade installations. Heat pumps and tenant electricity schemes for apartment buildings are part of the range. Advice on Berlin's SolarPLUS grant is included, which can lower the cost of adding a battery.

sunday solar suits owners planning a full energy upgrade rather than panels alone. The Neukölln firm designs combined concepts of solar, battery, heat pump and wallbox, and its own installation teams carry them out. Solar systems typically go up in one to two days and heat pumps in three to five. Smart meters and grant applications are organised during planning, so there is less paperwork for you.

Its strength lies in long experience with its own people: solarwerkstatt berlin installs only with long-serving employees and has an in-house planning department. The owner-managed craft business, founded by Holger Freyer, has worked in Berlin and Brandenburg for 30 years from Mahlow, just south of the city. Consultation on site and planning are free, and the firm registers the system with the grid operator. Clients get a thorough handover, which helps when you first read the monitoring data.

Solar GMI is a good fit for households that want more than a rooftop system, as the range runs from balcony power plants and solar carports to heat pumps and air conditioning. Its own fitters plan, supply and install everything in Berlin and Brandenburg. Battery storage comes through its Senec partnership, and heat pumps from Bosch, Elco and its own GMI Power line. Service packages with cleaning, monitoring and checks after storms cover the years after installation.

Techno Solar suits people who want a clear plan before committing, as every quote comes with a yield simulation and a module layout drawing. The Adlershof firm, run by master electrician Frank Meletzki, has worked in the trade for 30 years and is a certified Tesla partner for Powerwall batteries and wall chargers. The first assessment works from photos of the roof and meter cabinet. That saves an early site visit if you are only comparing options.

bts Solaranlagen is a sensible choice for owners of both houses and commercial roofs who want one local contact from the first calculation to handover. The firm in Marzahn plans, sells and installs photovoltaic systems, batteries and wallboxes with its own team. Each quote comes with a profitability calculation, and the system is handed over only after grid connection and commissioning. Advice on Berlin's SolarPLUS programme and KfW loans helps with financing.
