About us

Energy is an investment. We make sure it works.

SOL SERVICE Ltd. is a Bulgarian engineering company specialising in the design, construction, monitoring and technical maintenance of photovoltaic power plants.

The company was founded in 2011, initially focusing on the monitoring and technical maintenance of photovoltaic plants. The hands-on experience we gained, together with the growth of solar energy, gradually expanded our work into full engineering of photovoltaic projects – from the initial idea and feasibility study to construction, commissioning and ongoing management and maintenance.

Today we offer complete solutions for industry, households and renewable-energy investors, tailored to the technical specifics and economic goals of each project.

We work with established equipment manufacturers and suppliers and follow the latest developments in photovoltaic technology and battery energy storage systems (BESS).

From generation to intelligent energy management

Modern energy is no longer just about generating electricity.

Combining a photovoltaic plant with BESS, monitoring and automated control makes it possible to use or sell the energy produced at the most suitable moment.

That is why we develop solutions for the intelligent management of electricity generation and storage, including controlling PV plants and BESS according to consumption, the technical limits of the site and the dynamics of the electricity market.

Our aim is not simply to add a battery to an existing PV system. We analyse the generation and consumption of the specific site and look for the optimal balance between PV capacity, battery capacity and control strategy, so that the investment delivers the greatest practical and economic benefit.

For businesses, this means higher self-consumption of the energy they produce, lower peak loads, better cost control and greater predictability.

For households – a higher share of self-consumption, the option to use energy produced during the day in the evening, and greater energy independence.

Our goal is simple: to turn the generation, storage and management of electricity into a single, reliable and cost-effective system.

A complete solution from one partner

Our team brings together specialists with many years of experience in energy, electrical engineering, and the design, construction and operation of energy facilities.

We take care of the entire process:

  1. Consultation and survey
  2. Design and permitting
  3. Supply and construction
  4. Commissioning
  5. Monitoring
  6. Service and maintenance

This approach means we take responsibility not only for building a photovoltaic plant, but also for its reliable and efficient operation throughout its entire service life.

A long-term partner

Our work does not end when the plant is built.

Through monitoring, preventive maintenance, diagnostics and technical support, we aim to ensure maximum availability, high performance and a long service life for every system.

For us, the best proof of a job well done is the projects we keep servicing years after they were built – and the clients who choose SOL SERVICE again for their next investments.

SOL SERVICE – a partner for the entire life cycle of your energy project.

Our approach

For us, a good solar project is not measured only in installed kilowatts and megawatts.

It must be properly designed, well built, reliably managed and cost-effective.

That is why we take an individual approach to every project and look for the best technical solution for the specific site, consumption profile, grid-connection options and the client's investment goals.

More than a solar company

As SOL SERVICE grows, it is gradually moving beyond the boundaries of the traditional solar business.

Photovoltaic plants, battery systems, monitoring and intelligent energy management are increasingly becoming parts of one integrated system.

Through our subsidiary SOLAR E-DRIVE, we are also developing electric-mobility solutions. We are building our own charging centre, where electric vehicles will be able to use energy produced by our photovoltaic plant.

This is how we put into practice the philosophy behind our growth:

  1. Sun
  2. Generation
  3. Storage
  4. Management
  5. Consumption
  6. Electric mobility

We aim not just to build individual systems, but to create complete energy solutions with added value – solutions that help businesses and households use their own energy more efficiently and depend less on external energy sources.

Your solar partner. SOL SERVICE – from the energy of the sun to the way we use it.
