What inverters and panels do you use, and to what standard?

Panels are specified to IEC 61215 (performance and durability) and IEC 61730 (safety); inverters to IEC 62109. We install grid-tie, hybrid or off-grid inverters depending on whether you want to offset the bill, ride through dumsor, or both. The standards and the as-built spec are handed over in writing — not promised verbally.

How do we know the array is actually performing?

Every commercial array we commission comes with live monitoring — you and we can see real-time and historical yield per string, so underperformance shows up immediately instead of as a quiet shortfall on the bill. That monitoring is also how our O&M and decade workmanship warranty stay accountable.

Will the mounting damage or leak through the roof?

Not when it is engineered. We select the mounting system to your roof type — pitched, flat membrane or metal-deck — and detail the waterproofing and wind-load fixings so penetrations are sealed and rated. A cheap clamp-and-hope install is exactly what fails in the first rainy season; we engineer it and document it.

Rooftop Solar Array Installation

Solar AC Ghana designs and installs commercial rooftop solar PV arrays across Ghana — mounting, stringing, inverters and live monitoring, sized for real yield and handed over in writing. Same-day service line.

A rooftop solar PV array is one of the few capital items on a commercial building that pays itself back — but only if it is sized to the load, engineered to the roof, and monitored so you can see it working. Solar AC Ghana designs and installs commercial rooftop arrays across Ghana, by EC-licensed technicians. Call +233 27 000 0866 — we survey the roof and give you the price from that survey before any work starts.

What a Commercial Rooftop Array Involves

A rooftop array is not “panels on a roof.” Each part is engineered:

Mounting & Structure

The mounting system is selected to your roof — pitched, flat membrane, or metal-deck — and engineered to wind load, with waterproofed, rated fixings. This is where cheap installs fail in the first rainy season; we detail and document it.

Stringing & Inverters

Panels are wired into strings matched to the inverter’s voltage window, with grid-tie, hybrid or off-grid inverters chosen to your goal — offset the bill, ride through dumsor, or both. Inverters to IEC 62109, panels to IEC 61215 / IEC 61730.

Monitoring & Yield

Live monitoring is commissioned with the array, so real-time and historical yield per string is visible — underperformance shows up immediately, not as a quiet shortfall on the bill months later.

Documented Handover

You receive the as-built drawings, the IEC-referenced commissioning record, the monitoring login, and the workmanship warranty terms — in writing, not promised verbally.

What a Rooftop Array Project Covers

Phase	What we do
Survey	Measure roof, structure, orientation; read load + bills
Design	Panel layout, string design, inverter sizing to IEC
Mounting	Roof-type mounting, wind-load + waterproofed fixings
Stringing & inverter	Wire strings, terminate inverter, grid-tie/hybrid/off-grid
Commission	Test under load, bring monitoring online
Handover	As-built docs, commissioning record, monitoring login, warranty

How We Engineer a Rooftop Array

Survey the roof and the load — sized to real usage, not a brochure number.
Engineer the array and mounting — layout, stringing, mounting to IEC, price confirmed first.
Install, string and commission — tested under load, monitoring online.
Hand over in writing — as-built docs, commissioning record, warranty terms.

What It Costs — Honestly

No honest solar firm quotes a rooftop array before surveying the roof — the price depends on usable area, roof type, the load you are offsetting, and the inverter and mounting your building actually needs. We give you the price from the survey before any work starts, with the array sized to the load — not oversold to inflate the bill. Be wary of a flat per-kilowatt price quoted without anyone seeing your roof.

Commercial Tier — Built to Standard

This is our institutional and commercial discipline: corporate facilities, financial institutions, data centres, hospitality and high-end residences. Every commercial array is engineered to IEC 61215 / IEC 61730 (panels) and IEC 62109 (inverters), installed under the EC Solar PV licence regime (L.I. 2449 and the Energy Commission Solar PV licence under Act 832), commissioned with live monitoring, and backed by our 10-year workmanship warranty and O&M — see Decade Workmanship Warranty & O&M.

Same-Day Service Line

A commissioned array also gets a fault response. If monitoring flags a string drop, an inverter fault, or a yield shortfall, our same-day service line responds across Greater Accra — call +233 27 000 0866. Diaspora owners and estate managers: we attend, diagnose, and report on your property.

Frequently Asked Questions

How big a rooftop array do we need? Sized from your usable roof area, load profile and bills — not a round kilowatt off a brochure. We survey first and give you the price from that survey before any work starts.

What inverters and panels, to what standard? Panels to IEC 61215 / IEC 61730, inverters to IEC 62109 — grid-tie, hybrid or off-grid to your goal. Spec handed over in writing.

How do we know it is performing? Live monitoring per string, real-time and historical — underperformance shows up immediately, not as a quiet shortfall on the bill.

Will the mounting leak through the roof? Not when engineered. Mounting selected to your roof type, waterproofing and wind-load fixings detailed and documented — call +233 27 000 0866.
