The verdict in three sentences
A Dubai solar company operating 45 rooftop and ground-mount plants that hears about a fault from the client loses days of generation per incident and weakens its PPA relationships. An asset management platform that centralises inverter data over 4G, raises alerts and opens maintenance tickets lifts availability from 92 to 98 % within a few months of operation. UAE integrators quote USD 70,000 to 150,000 for this scope as a 2026 order of magnitude, for a 4 to 6 month project.
Where 8 % of availability disappears
Typical UAE commercial and industrial portfolios mix warehouse roofs in Jebel Ali, factory roofs in Sharjah and carports across Dubai, often connected under the Shams Dubai scheme. Each site has its own inverter brand and vendor portal. Nobody checks 45 portals every morning, so faults surface late, and access permits for industrial sites stretch the outage further.
| Incident type | Yearly frequency (45 sites) | Current detection time | With monitoring | Generation saved per incident |
|---|---|---|---|---|
| Inverter fault | 60 to 90 | 2 to 4 days | under 1 hour | 1 to 3 days |
| Tripped breaker after grid event | 30 to 50 | 1 to 3 days | minutes | 1 to 2 days |
| Disconnected string | 40 to 70 | 10 to 30 days | 1 day (yield gap) | 1 to 4 partial weeks |
| Soiling and sandstorms | weekly risk | unmeasured | performance ratio alert | 5 to 15 % of yield |
| Communication loss | 50 to 100 | undetected | 30 minutes | indirect |
| Hot spots and module damage | 10 to 20 | at annual inspection | gradual underperformance alert | variable |
Soiling is the Gulf-specific cost. After a sandstorm, yield can drop 10 to 25 % until cleaning. A platform that compares expected output (irradiance, installed capacity) to actual output tells the O&M team which roofs to clean first, rather than following a fixed calendar.
What the platform must include
| Module | Function | Budget share | 2026 order of magnitude |
|---|---|---|---|
| Data collection | 4G gateways, Modbus inverter protocols, 5 to 15 minute data storage | 25 % | USD 17k to 38k |
| Dashboard and alerts | Site map, performance ratio, SMS and WhatsApp alerts | 20 % | USD 14k to 30k |
| Maintenance and tickets | Tickets, technician dispatch, offline mobile app, spare parts | 20 % | USD 14k to 30k |
| Client and investor reporting | Generation, availability, avoided CO2, monthly PPA statements | 15 % | USD 10k to 22k |
| Integrations | PPA billing, DEWA meter readings, accounting | 10 % | USD 7k to 15k |
| Rollout and training | Commissioning 45 sites, training 8 to 15 technicians | 10 % | USD 7k to 15k |
Hardware is excluded: a communication gateway usually costs USD 300 to 800 per site, plus USD 10 to 25 a month in data. Across 45 sites, budget USD 14,000 to 36,000 on top of software.
Investor reporting matters as much as fault detection. Funds and PPA offtakers expect monthly statements with guaranteed versus actual yield, availability and avoided emissions. Producing these by hand often takes a week every month.
Vendor portals, commercial SaaS or custom build
| Option | Initial cost | Annual cost | Multi-brand | Integrated maintenance |
|---|---|---|---|---|
| Inverter vendor portals | 0 | 0 | no, one portal per brand | no |
| Commercial monitoring SaaS | USD 10k to 30k | USD 2 to 6 per kWp per year | yes | partial |
| Industrial SCADA | USD 80k to 200k | 10 to 15 % | yes | no, separate tool |
| Custom build with an integrator | USD 70k to 150k | 10 to 15 % | yes | yes, with PPA reporting |
At Kolonell, this kind of platform falls under our medium application grid, 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), or complex, 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) once PPA billing and meter integrations are included. Exact pricing is on quote after an inventory of inverter brands. Maintenance follows our 35,000, 75,000 or 120,000 FCFA monthly plans (53, 114 or 183 EUR).

Omar, Head of Operations at a solar developer in Dubai, runs 45 plants totalling 18 MWp. With a specific yield of about 1,700 kWh per kWp per year, the portfolio can generate 30,600 MWh. At 92 % availability, 2,448 MWh are lost.
- Target availability: 98 %, so 1,836 MWh recovered a year
- Average PPA tariff: USD 0.10 per kWh
- Gain: 1,836,000 × 0.10 = USD 183,600 a year
- Diagnostic truck rolls avoided: 120 × USD 150 = USD 18,000
- Investment: USD 110,000 software + USD 25,000 gateways = USD 135,000
- Payback: 135 / 201.6 × 12 ≈ 8 months
FAQ
Do we have to replace existing inverters?
Rarely. Most inverters installed since 2018 expose a Modbus or RS485 port readable by a gateway. An inventory of 45 sites takes 1 to 2 weeks and flags the few models to replace.
How long until the platform is live?
Plan 4 to 6 months: 1 month of scoping and inventory, 2 to 3 months of build, 1 to 2 months of progressive site commissioning. The first 10 sites are monitored from month three.
Can it track cleaning effectiveness?
Yes. The platform logs each cleaning visit and measures the yield gain over the following 7 days, which typically shows whether a 2-week or 4-week cleaning cycle pays for itself on each roof.
Will investors accept the reports?
They reproduce the indicators required in PPAs and fund agreements, exported monthly to PDF and spreadsheet. A week of monthly consolidation drops to under an hour.
Can technicians work offline?
Yes, the mobile app keeps tickets, site sheets and checklists offline and syncs on reconnection. Technicians typically handle 4 to 5 visits a day instead of 3.
