One of the most common questions we hear from prospective clients is: "I want solar panels on my factory roof — how does this actually work?" The solar EPC process involves engineering, procurement, construction, and post-installation services, and for a first-time buyer it can seem like a black box. This article aims to make it transparent, phase by phase.
The process begins with a phone call or meeting where we discuss your energy consumption, roof type, available area, financial goals, and preferred timeline. Within 24–48 hours, we schedule a free on-site assessment. Our engineer will:
What you need to provide: site access, 12 months of electricity bills, roof plans or building drawings (if available).
Back in the office, our engineers run a full PVsyst simulation using satellite-calibrated TMY3 meteorological data. The output includes:
We present this in a structured proposal meeting. No hard sell — just numbers. If the numbers work for you, we proceed. If not, we part as friends.
After contract signing, two parallel tracks begin:
Building Permit Track: We prepare the architectural and structural drawings required by the municipality. In Antalya, industrial rooftop solar permits typically take 4–8 weeks. We handle the entire application and follow-up.
TEDAŞ Grid Connection Track: We submit the net metering connection application to TEDAŞ Antalya Distribution. This includes a completed application form, electrical single-line diagram, and building permit reference. TEDAŞ issues the Connection Agreement within 4–10 weeks.
In parallel with permitting, we order equipment. Our standing supply agreements with Jinko, LONGi, Huawei, SMA, and racking manufacturers mean 4–6 week delivery for most projects. For large projects (>1 MWp), we sequence equipment delivery to arrive just-in-time for installation.
Our certified installation crew takes over. A typical 500 kWp installation runs 10–15 working days. The sequence is:
EHS compliance is managed throughout: all operatives wear harnesses on roofs, confined spaces are assessed, and a daily safety brief is conducted. We provide a complete EHS file to the client on project handover.
Before connecting to the grid, we conduct pre-commissioning tests: IV curve tracing for each string (using a Solmetric SunsEye tracer), insulation resistance tests, earth continuity checks, and inverter self-test. A Commissioning Report is prepared.
We then coordinate with TEDAŞ for the official grid commissioning inspection. A TEDAŞ engineer visits the site, verifies the installation against the Connection Agreement, and activates the bidirectional smart meter. This typically takes 2–4 weeks to schedule after our application.
Client receives: As-built drawings, equipment warranties, O&M manual, SCADA login credentials, and the signed TEDAŞ Commissioning Protocol. We conduct a 2-hour training session on the monitoring platform.
From day one of operation, your system generates electricity and your savings begin accruing. If you have an O&M contract with us, we start monthly monitoring reports and schedule the first preventive maintenance visit at 6 months.
