Rooftop and ground-mount solar installation
We analyse your consumption to size the system correctly, then handle design, authority approvals, installation and commissioning from a single hand.
- Free site survey and feasibility
- TEDAŞ and utility approval process handled
- Storage and EV charging integration
System size is set by your consumption, not by panel prices
The most expensive mistake in a solar investment is a system sized without reference to the actual need. We first review twelve months of consumption data, your tariff structure and site conditions — the capacity decision comes out of those three inputs. Only then do we talk about design and price.
We run feasibility, design, installation and commissioning end to end for rooftop and ground-mount solar plants. We size the system from your consumption profile and follow the TEDAŞ and utility approval process. Storage and EV charging needs are solved within the same project.
- Capacity decided from the consumption profile
- Roof structure and shading assessment
- Self-consumption and net-metering scenarios
- Transparent, data-based payback calculation
Which set-up fits you?
Solar is not a single kind of installation. Your grid connection, the hours you consume and the site itself decide which type we build. That decision is made together during the survey.
- On-Grid
Grid-connected system
Generation is consumed on site first; the surplus is exported and offset against the bill. With no battery it has the lowest upfront cost and the fastest payback. When the grid goes down the system stops for safety.
- Off-Grid
Grid-independent system
Built where there is no grid, or where bringing one in is prohibitively expensive. Generation is stored in a battery bank and consumption is drawn from it. Sizing is critical here: the system has to carry the night and the cloudy days as well.
- Hybrid
System with storage
Uses the grid connection and a battery together. Surplus daytime generation is stored and used in the evening; critical loads stay up during an outage. It earns its cost in facilities where an outage stops work and on tariffs with peak pricing.
- Ground-Mount
Ground-mounted plant
Used when roof area is insufficient or the investment is generation-led. Ground survey, mounting structure, site security and the distance to the grid connection point are what drive the capacity decision.
- Agricultural
Powering irrigation pumps
In the irrigation season consumption concentrates in daylight hours — one of the rare load profiles that lines up directly with solar generation. Depending on pump size we build either a direct drive-fed set-up or a net-metered one.
- EV Integration
Combined with EV charging
A charging point is one of the largest single loads on a site, and adding it later usually means a capacity increase application. Designed into the same project, the switchgear and capacity are sized for it from the start.
What we take on in a solar project
All of the items below sit in a single contract. You do not chase separate subcontractors — you follow one point of contact.
- 01
Feasibility and consumption analysis
We produce a realistic capacity and yield estimate from twelve months of consumption data, your tariff structure and site conditions.
- 02
Structural and shading assessment
Roof load capacity, orientation and tilt, and the shading effect of surrounding structures all feed into the capacity decision.
- 03
Design and authority approvals
Single-line diagrams, layout and earthing designs are prepared; TEDAŞ and utility applications are run on your behalf.
- 04
Mounting structure and panel installation
Mounting system selected for the roof type, installation that does not compromise waterproofing, and panel layout executed on site.
- 05
DC/AC cabling and switchgear
String cabling, DC and AC protection panels, inverter connections and the earthing system.
- 06
Commissioning, testing and monitoring
Insulation, string and earthing tests, yield verification, documentation handover and remote monitoring setup.
A few lines are enough for a survey and a quote
Leave your number and we will call back the same day. The survey is free; the quotation comes itemised, with quantities and lead times.
- Free site survey
- Itemised, transparent quotation
- One contact, one schedule
From survey to first generation
- 01
Site survey and feasibility
We visit the site, review your consumption data and produce a realistic capacity and preliminary budget.
- 02
Design and approval
Electrical and structural designs are prepared, and the TEDAŞ and utility approval process is followed on your behalf.
- 03
Supply and installation
Panels, inverters and mounting structures are supplied; installation is completed to plan and to OHS rules.
- 04
Commissioning and handover
Tests are carried out, the system is commissioned, documentation is handed over and monitoring support begins.

Frequently asked
-
It depends on capacity and on authority approvals. In most projects design and approval take longer than the installation itself. After the survey we give you a dated, project-specific schedule.
-
Four things decide it: orientation, tilt, load capacity and shading. We assess all four on site. If the roof is not suitable we say so plainly, and suggest an alternative location if there is one.
-
Payback depends on the consumption profile, system capacity, roof or land conditions and current legislation. Rather than quoting a generic figure, we prepare a technical and economic assessment specific to your project data.
-
Yes. We run the application, design approval and connection processes on your behalf and take on the authority follow-up, so you track everything through one contact.
-
Yes. We supply panels, inverters, batteries and mounting materials from our own supply network. If you prefer to supply your own equipment, we can work on an engineering and installation scope only.
-
In a grid-connected system your generation covers your own consumption first. The surplus is exported and deducted from what you draw during the billing period. How much actually offsets depends on how your consumption is spread across the day — which is why we size capacity against your consumption hours.
-
It works, but produces less. Panels generate from diffuse light too, just not as much as in direct sun. The calculation is built on the sum of summer and winter generation across the year; system size is never set by looking at a single day. In off-grid systems, winter output is the decisive input for capacity.
-
With no moving parts the maintenance load is low. For most sites an annual panel cleaning, a check of the connection points and a review of generation data through the inverter is enough. Where we install remote monitoring, a drop in output shows up before you notice it.
-
You can, but if the design was not prepared for it, an inverter change or a capacity increase application may be needed. If storage or charging is on the horizon, say so at the survey — we size the switchgear and capacity accordingly and the later job stays much smaller.
