Products and packages

We have arranged our services into clear packages according to what you are protecting – a house, a building, a PV system or a solar park. Pick the one closest to your situation and we will tailor it at the survey.

Each package says clearly what we supply, install and test – so you know what you are getting before we have even met.

You do not need to be an engineer to choose. Go by the type of site and by whether you need earthing only, lightning protection or complete protection.

  • One system – earth electrode, air terminal, down-conductors and SPDs
  • Itemised quote after a site survey
  • Test certificate with every package

Houses and buildings

From earth electrode to complete protection

Three levels for the house – earthing, lightning protection and complete protection – and a separate solution for apartment blocks, offices and halls. Each level builds on the one before.

Earthing for a house

The foundation of every lightning protection and surge protection system.

Suitable for: Houses with no earth electrode, or with an old, corroded one; new builds at the foundation stage.

What is included

  • Site survey and soil measurement
  • Ring or rod earth electrode to suit the ground
  • Connection to the board and equipotential bonding

Lightning protection for a house

Air terminal, down-conductors, earth electrode and entry SPD – done in one or two days.

Suitable for: Detached houses and villas, especially on open or elevated sites; houses with a chimney, aerials or solar panels.

What is included

  • Risk assessment and lightning protection class
  • ESE air terminal on a mast or conventional rods on the roof
  • Two down-conductors with test joints

Recommended

Complete protection for a house

Lightning protection, earthing and surge protection as one system.

Suitable for: Houses with an inverter, heat pump, air conditioners and electronics – when you want to protect both the building and the equipment.

What is included

  • Everything in "Lightning protection for a house"
  • Check and improvement of the earth electrode
  • Type 2 SPDs in sub-boards and Type 3 in front of sensitive equipment

Lightning protection for buildings and halls

Apartment blocks, offices, warehouses and halls – designed, installed and documented for acceptance.

Suitable for: Owners' associations, developers and companies – flat, metal and membrane roofs; sites that must pass an acceptance committee.

What is included

  • Risk assessment, class and a design with drawings
  • Mesh, rods or ESE terminals to suit the roof
  • Down-conductors around the perimeter with test joints

Photovoltaic systems

Protection for every plant – from rooftop to park

The modules are metal at the highest point of the site, wired to expensive electronics. Three packages by scale – a home system, a rooftop plant and a ground-mounted park.

Protection for a home PV system

Bonding of the mounting structure and SPDs for the inverter – the minimum for every home PV system.

Suitable for: Houses with a new or existing PV system, whoever installed it.

What is included

  • Survey of the modules, cables, inverter and board
  • Bonding of the mounting structure to the earth electrode
  • DC-side SPD at the inverter

Protection for a commercial rooftop PV plant

Isolated lightning protection, earthing and SPDs at every inverter.

Suitable for: Companies and investors with a plant on the roof of a hall, warehouse or office building.

What is included

  • Risk assessment and a solution to suit the building's lightning protection
  • Isolated air terminals without shading the modules
  • Earthing and equipotential bonding of the mounting structure

Protection for a ground-mounted solar park

Earthing grid, air terminals and SPDs – from the string combiner box to the substation.

Suitable for: Investors, EPC contractors and operators of ground-mounted plants.

What is included

  • Risk assessment and a design for the complete protection
  • Earthing grid for the tables, inverters, substation and fence
  • Air terminals along the rows, or the structure as a natural air terminal

The packages describe the typical scope of work, not a ready-made quote. Each one is adapted to the site after a survey – free of charge in Sofia and the surrounding region. Every installation is handed over with a test certificate.

FAQ

Frequently asked questions

How do you arrive at the quote?
Once you get in touch we arrange a survey – free in Sofia and the surrounding region. On site we agree which package fits, and within a few days you receive an itemised quote: materials, labour, testing and documents.
Is a test certificate included?
Yes, in every package. The certificate is needed for acceptance (Act 16), for the insurer and for future periodic inspections.
How long does installation take?
Earthing or an SPD in a board – up to one day. Lightning protection for a house – one to two days. Buildings and solar parks – to a schedule stated in the quote.
What warranty do you give?
A written warranty on our workmanship and the manufacturer's warranty on the materials. The terms are stated in the quote and the contract.
Can I combine packages?
Yes. The house packages are tiered – you can start with earthing and add the rest later. The services can be attached to any package or ordered on their own.
