National photovoltaic project coordination
Solar panel and photovoltaic system services across Romania
Looking for photovoltaic panels for a house, apartment building, office, shop, hotel, warehouse, farm or industrial property? Prestari Servicii receives the request, clarifies consumption, location, roof or land, existing electrical supply, objectives and available documents, then directs it to a suitable independent photovoltaic provider and the authorised professionals required for the project.
Requests can be assessed in every Romanian county for private investments, self-consumption projects, hybrid systems with batteries, selected backup loads, commercial installations and suitable ground-mounted projects. The provider confirms design, equipment, electrical work, structural requirements, grid procedures, documentation, travel, timing and price before the client accepts the work.
Prestari Servicii is a contact and coordination point. It is not presented as the direct installer, electrical designer, grid operator, energy supplier or public-funding authority. Installation, design, verification and commissioning are performed by the providers and authorised professionals responsible for the contracted activities.
24/7 REQUEST HANDLING
You can submit a photovoltaic request during the day or at night. Tell us the locality and county, property type, recent electricity consumption, available roof or land area, connection type, objectives, preferred period and whether you already have bills, plans, roof photographs, an energy certificate, a connection document or another offer.
Requests are handled 24/7, but a site survey, installer, authorised electrician, grid procedure, equipment allocation, public-funding route or installation date is not guaranteed before the actual project is reviewed. The selected provider confirms what it can deliver and which steps depend on third parties.
Electrical and fire safety
Do not open live electrical panels, inverters, batteries, DC combiner boxes or protection equipment. Do not connect panels or plug-in generation equipment through improvised circuits. If there is smoke, fire, electric shock, arcing, a burning smell, damaged cables or another immediate hazard, keep people away and contact the appropriate emergency, distribution or competent technical service.
HOW IT WORKS
1You describe the property and objective
Send the locality, property use, electricity consumption, photographs, available area, current electrical supply and whether you want self-consumption, export, storage or backup.
2We clarify the technical starting point
We establish the roof or land type, orientation, shading, structural condition, electrical capacity, main panel, earthing, cable routes, ownership, existing documents and whether a survey is needed.
3We identify the suitable provider
The request is directed to an independent photovoltaic company, authorised electrician, designer, structural specialist or another competent professional appropriate to the work.
4The provider assesses and confirms the proposal
The provider confirms system size, layout, equipment, protections, mounting, electrical works, documents, grid steps, installation schedule, exclusions, warranties and price.
5You approve the project
The project proceeds only after the scope, responsibilities, equipment, performance assumptions, payment stages, documentation and written commercial terms are understood and accepted.
WHAT A PHOTOVOLTAIC PROJECT SHOULD SOLVE
A photovoltaic system should be selected for the property's actual consumption and objectives rather than for a generic number of panels.
Reducing purchased electricity
Self-consumption can reduce the amount of electricity bought from the grid when production and demand occur at compatible times. Results depend on consumption, orientation, shading, equipment, weather, tariffs and operating behaviour.
Using available roof or land responsibly
The largest system that physically fits is not automatically the most suitable. Roof condition, structure, cable routes, grid capacity, investment plan and future consumption all matter.
Preparing for an electric vehicle or heat pump
Future loads can change the preferred size and control strategy. The project should distinguish current demand from realistic planned demand.
Storing solar energy
A battery can shift energy to another time, supply selected loads or support a hybrid operating strategy, but it adds cost, conversion losses, technical constraints and maintenance considerations.
Commercial self-consumption
Businesses may benefit from production during operating hours. The analysis should use the actual load profile, not only annual totals.
Resilience and selected backup loads
Not every grid-connected photovoltaic system supplies a property during an outage. Backup requires compatible equipment, separation, switching and a defined set of loads.
PHOTOVOLTAIC SYSTEM TYPES
The provider should explain the proposed architecture, its operating limits and what happens during a grid outage.
Grid-connected systems
An on-grid system works with the public grid and can support self-consumption and, where applicable, export. Standard grid-connected inverters normally stop during an outage unless a compatible backup solution is designed.
Hybrid systems
A hybrid system can combine panels, a compatible inverter, battery storage and selected backup circuits. The exact functionality differs significantly between equipment models and configurations.
Systems with batteries added later
Some projects can be prepared for later storage, but future compatibility must not be assumed. Inverter type, voltage architecture, communication, protections and manufacturer support should be checked from the beginning.
Off-grid and remote systems
A stand-alone system requires careful analysis of daily and seasonal loads, battery autonomy, backup generation, critical-use priorities and the consequences of prolonged poor weather.
Zero-export or controlled-export systems
Certain commercial or technical situations may require limiting export. The provider confirms the control equipment, metering, settings and applicable grid requirements.
Ground-mounted systems
Ground structures need suitable land, geotechnical and structural consideration, cable routes, drainage, access, security, planning checks and vegetation management.
PHOTOVOLTAIC SYSTEMS FOR HOMES
Residential projects should be understandable to the homeowner and technically compatible with the building.
Consumption-based sizing
Provide at least several recent bills where possible. Monthly patterns, heating, cooling, cooking, hot water, remote work, electric vehicles and future plans can affect the proposal.
Single-phase and three-phase properties
The provider checks the existing supply, approved power, phase distribution, protection equipment and whether upgrades or a different system arrangement are necessary.
Roof layout and usable area
Chimneys, dormers, skylights, antennas, shading, safety distances, roof access and maintenance corridors reduce the area that can be used responsibly.
Household self-consumption
Daytime appliances, hot-water production, heat pumps, pool equipment and EV charging may be scheduled to use more solar production, subject to user needs and correct controls.
Backup for essential circuits
The client should identify what is genuinely essential during an outage: communications, lighting, refrigeration, heating controls, pumps or medical-support equipment. The provider confirms power and autonomy limits.
Clear handover
The owner should receive the contracted documentation, equipment identification, operating instructions, monitoring access, shutdown procedure, maintenance guidance and warranty information.
SYSTEMS FOR COMPANIES, WAREHOUSES, FARMS AND INDUSTRY
Commercial systems require a more detailed review of load, operating hours, roof rights, electrical distribution, safety and project responsibility.
Offices, shops and hospitality
Daytime consumption may align well with photovoltaic production. Air conditioning, refrigeration, kitchens, laundry, charging and guest services should be included in the load profile.
Warehouses and logistics buildings
Large roofs can offer substantial area, but structural capacity, roof warranty, waterproofing, smoke ventilation, skylights, fire compartments and future roof maintenance must be coordinated.
Production and industrial sites
Machines, motors, compressed air, cooling, process loads and shifts can create large variations. Measurements may be needed before responsible sizing.
Farms and rural properties
Projects may support milking, refrigeration, irrigation-related loads, pumps, workshops, grain handling, accommodation and other seasonal activities.
Multi-site businesses
A portfolio should not receive one copied solution. Each connection point, roof, consumption profile and operating plan must be evaluated.
Power management and export control
Larger projects may require monitoring, dynamic control, protection coordination, export limitation or technical studies depending on the configuration.
ROOF, LAND, STRUCTURE AND SHADING ASSESSMENT
A solar proposal cannot be separated from the surface that supports it.
Roof condition before installation
A roof that is leaking, degraded or near replacement should be repaired first. Panels can make later access and dismantling more expensive.
Structural suitability
The mounting system, panels, wind and snow actions, existing roof construction and fixing method must be considered. Where required, the project should involve a competent structural professional.
Waterproofing and penetrations
Mounting details must preserve or correctly restore waterproofing. The responsible provider should explain how penetrations, flashings or ballast are handled.
Orientation and inclination
South-facing surfaces are not the only possible option. East-west layouts may better match consumption in some projects. The actual proposal should use site-specific production estimates.
Shading
Trees, nearby buildings, chimneys, equipment and terrain can reduce output. Seasonal shading and future vegetation or construction should be considered.
Ground conditions
Ground-mounted systems require drainage, vegetation control, foundations or piles, access, fencing and secure cable routes.
Link to specialist building-envelope work
For roof repair, waterproofing, façade or insulation work, use the national roofing, waterproofing and thermal insulation service.
PANELS, MOUNTING STRUCTURE AND INSTALLATION QUALITY
A system is more than the visible modules. Compatibility and workmanship across every component affect safety and service life.
Photovoltaic modules
The proposal should identify manufacturer, exact model, rated power, dimensions, declared performance, product warranty and compatibility with the layout and inverter.
Mounting structure
Rails, hooks, clamps, fasteners, ballast and corrosion protection must suit the covering, structure, wind exposure and manufacturer instructions.
Module layout
Rows should respect fixing zones, roof edges, access, shading, fire and maintenance needs. A visually dense layout is not automatically a good technical layout.
DC cable management
Cables should be properly supported, protected from sharp edges, water accumulation, heat and movement, and kept away from inappropriate contact with the roof.
Labelling and safe isolation
The system should have the labels, warning signs and isolation arrangements required by the selected design and applicable practice.
Work at height
Installation requires suitable access, edge protection, fall protection, exclusion zones and weather decisions. Safety measures should not be removed merely to reduce cost.
INVERTERS, ELECTRICAL PROTECTIONS AND EARTHING
The inverter and electrical design determine how the photovoltaic generator interacts with the building and grid.
Inverter selection
The provider should explain power, input configuration, voltage limits, string design, efficiency, communication, environmental rating and future-storage compatibility.
DC and AC protections
The design may include isolation, overcurrent protection, surge protection, appropriate enclosures, cable protection and coordination with the existing installation.
Main switchboard and connection point
The provider checks available space, equipment condition, protection rating, conductor sizes, selectivity and the correct point for connecting the system.
Earthing and equipotential bonding
Existing earthing should be assessed. The photovoltaic structure, equipment and protections must be integrated according to the applicable technical solution.
Lightning and surge risk
The presence of an external lightning-protection system, building exposure and cable routes may affect the design. Surge protection is not a substitute for a complete risk-based solution where one is required.
Monitoring and communications
Internet access, data logger, portal ownership, user accounts, permissions and long-term availability should be clarified at handover.
BATTERIES, HYBRID SYSTEMS AND BACKUP
Battery storage should be justified by a defined operating need.
Increasing self-consumption
A battery can store daytime surplus for evening use, but capacity should reflect actual surplus and consumption rather than a generic package.
Backup power
The proposal must state which circuits are backed up, maximum output, surge capability, usable energy, switching time and what happens when the battery is empty.
Whole-property versus selected-load backup
Supplying an entire property during an outage can require much greater power and capacity than supplying a small critical-load board.
Battery location
Temperature, ventilation, moisture, access, impact protection, fire considerations, manufacturer clearances and emergency isolation affect the location.
Compatibility and communication
Battery, inverter, meter and management system must be supported as a compatible combination. Similar connectors do not prove compatibility.
Operating reserve and battery life
The provider should explain usable capacity, reserve settings, expected cycling, software updates, maintenance and warranty conditions without promising a fixed lifespan independent of use.
PROJECT DESIGN, AUTHORISED ELECTRICAL WORK AND DOCUMENTS
Electrical activities must be performed within the authorisation and professional competence applicable to the work.
Technical proposal and system layout
The provider should document module arrangement, equipment, strings, routes, protections, connection, monitoring and, where included, backup circuits.
Authorised professionals
Design, execution, verification and other regulated electrical activities must use appropriately authorised persons or economic operators. The client should be able to verify the relevant status in official registers.
Equipment documentation
Datasheets, declarations, certificates, manuals and warranty documents should correspond to the equipment actually installed.
Commissioning and tests
The contracted scope should state the inspections, measurements, settings, functional tests, monitoring setup and documents delivered at commissioning.
Ownership and approvals
Apartment buildings, shared roofs, rented properties, protected buildings and sites with multiple owners may require rights, approvals or formal decisions before work.
Roof and fire coordination
The photovoltaic design must not ignore roof warranty, fire compartments, smoke vents, access paths, façade routes and emergency-service considerations.
GRID CONNECTION AND PROSUMER PROCEDURE
Grid and prosumer procedures can change and may depend on the connection point, system capacity and current ANRE and distribution-operator requirements.
Existing consumption point
The provider clarifies whether the photovoltaic system is added to an existing consumption point and what connection or certification steps apply.
Connection request and technical documents
The process may involve forms, equipment data, single-line diagrams, certificates, declarations, commissioning records and other documents required for the specific case.
Metering
The distribution operator determines the metering work and stages under its responsibility. The installer cannot promise a date controlled by the operator.
Supplier relationship
Commercial treatment of exported electricity involves the applicable legal framework and the customer's supplier arrangements. Conditions should be checked against current official information.
System operation before final procedure
The provider must explain when and how the system may be operated and what settings or export limitations apply during intermediate stages.
No guaranteed status or deadline
Prestari Servicii does not guarantee prosumer certification, approval, meter replacement, payment, compensation mechanism or institutional processing time.
PRIVATE PROJECTS AND PUBLIC FUNDING PROGRAMMES
A technically suitable private installer is not automatically validated for a specific funding programme.
Private investment
The client selects the provider and commercial solution under the agreed contract, subject to legal and technical requirements.
AFM or another programme
Programme rules, budgets, eligible equipment, applicant conditions, deadlines and validated-installers lists can change. The current official programme documents must be checked at the time of the request.
Existing funded project
If the applicant already has an approved file or selected installer, clarify the programme edition, status, deadlines, documents and what change or support is requested.
Replacing or changing an installer
Any change must follow the active programme rules and official procedure. Prestari Servicii does not promise that a change will be accepted.
No invented programme claims
Do not publish a fixed grant amount, contribution, deadline, required capacity or battery rule on this evergreen service page. Such details belong in a separately researched, dated information page.
PRODUCTION ESTIMATES, SAVINGS AND PAYBACK
A production estimate is based on assumptions, not a guaranteed result.
Inputs to an estimate
Location, orientation, inclination, shading, module and inverter data, losses, weather dataset and system availability affect the result.
Consumption match
Financial benefit depends on how much energy is used directly, stored, exported or purchased at different times and under applicable contracts.
Tariffs and rules can change
Electricity prices, taxes, compensation arrangements and programme conditions should not be treated as permanent.
Degradation and downtime
Modules, inverters, dirt, shading, faults and outages can affect long-term production. Maintenance and monitoring matter.
Payback is project-specific
Prestari Servicii and the page must not advertise a universal recovery period. The provider may present a calculation only with clear assumptions and limitations.
MONITORING, MAINTENANCE AND FAULT DIAGNOSIS
A system should remain observable after handover.
Monitoring review
The user should know where to see production, consumption, battery state, faults and connectivity status.
Visual inspection
Loose or damaged components, cable movement, corrosion, debris, animal damage, roof problems and vegetation can require attention.
Cleaning
Cleaning is not needed on the same schedule for every system. Roof pitch, rainfall, dust, agricultural activity, birds and access influence the decision. Unsafe roof cleaning should not be attempted by the owner.
Electrical and thermal checks
Qualified providers may inspect connectors, terminations, protection devices, strings, inverter behaviour and abnormal heating where appropriate.
Inverter or communication faults
Support may involve error-code review, connectivity, firmware, sensors, meters, grid parameters or equipment service under the manufacturer's process.
Performance investigation
A lower reading does not automatically mean panel failure. Weather, shading, clipping, export limitation, outages, temperature, dirt and monitoring errors must be separated.
INFORMATION TO SEND WITH THE REQUEST
Exact location
State the village, town or city and county. For remote properties, include access and practical travel information.
Electricity consumption
Send recent bills or monthly kWh values where possible, with personal and payment data removed if unnecessary.
Connection and electrical details

FREQUENTLY ASKED QUESTIONS
Are photovoltaic services available in every Romanian county?
Requests can be submitted from every county. The provider confirms survey, installation, documentation, grid and maintenance availability for the exact project.
Does Prestari Servicii install panels directly?
No. Prestari Servicii clarifies and routes the request. The independent provider and authorised professionals contract and perform the work.
How many panels do I need?
The answer depends on consumption, available area, orientation, shading, panel model, inverter design, future loads and project objective.
Can I become a prosumer?
The applicable procedure depends on the current legal and technical framework and the connection point. The provider clarifies documents and steps, while the distribution operator and other parties control their stages.
Can I install panels through Casa Verde?
A request can be discussed, but the current programme, applicant status and validated-installer list must be checked on official AFM information. Funding is not guaranteed.
Can photovoltaic panels be installed on any roof?
No. Covering condition, structure, waterproofing, fixing, wind and snow exposure, access, shading and maintenance must be suitable.
Should the roof be repaired first?
Yes, when the roof is degraded or likely to require work soon. Removing and reinstalling panels later can add cost and risk.
What is the difference between on-grid and hybrid?
An on-grid system works with the grid and usually stops in an outage. A hybrid configuration can include compatible batteries and backup functions, depending on design.
Will panels power my house during a blackout?
Not automatically. Backup requires compatible inverter functions, batteries or another source, safe separation and designated circuits.
Can a battery be added later?
Sometimes. Future compatibility depends on inverter architecture, battery voltage, communication, software and manufacturer support.
Are systems available for companies and farms?
Yes. Requests can be assessed for offices, shops, hotels, warehouses, production sites, farms and rural properties.
Can the system be installed on land?
Yes, where the land, planning, structure, drainage, access, cable routes, grid and security conditions permit.
What documents should I send?
Send recent consumption, location, property and connection information, roof or land photographs, existing offers and funding documents if applicable.
How long does installation take?
Survey, design, equipment, roof work, electrical preparation, weather, grid stages and project size affect timing. No universal completion time should be promised.
How much electricity will the system produce?
The provider can prepare a site-specific estimate using equipment and location assumptions. Actual production varies with weather, shading, temperature, faults and maintenance.
How quickly will the investment pay back?
There is no universal answer. Costs, self-consumption, tariffs, exported energy, financing, maintenance and future rules affect payback.
Do panels need maintenance?
They need monitoring and periodic inspection. Cleaning and technical service depend on location, access, dust, faults and manufacturer requirements.
What warranties apply?
The written offer should separate module, inverter, battery, mounting and workmanship warranties and state who honours each one.
Can you coordinate a project for an owner living abroad?
Yes. The request can include photographs, survey coordination, offers, reporting and contact with suitable providers, subject to legal authority and property access.
What happens if the electrical installation is old?
The provider assesses the main panel, conductors, protection, earthing and capacity and states any upgrades required before connection.
