Solar panels can reduce a Dubai commercial laundry's electricity costs. They do not, by themselves, replace the gas, diesel or purchased steam used to heat its machines. Before comparing rooftop PV proposals, identify which parts of washing, drying and finishing are actually paid for through your electricity meter.
A laundry can have a promising solar project and a substantial boiler bill left afterwards. The investment decision is whether PV works against the existing electrical demand, not whether sunshine can be credited against every invoice carrying the word “energy”. This guide is for owners and authorised operations or finance teams at DEWA-connected commercial laundries.
Start with the heat source, not the number of machines
A machine's plug or electrical connection does not prove its process heat is electric. A gas-heated or steam-heated dryer still needs electricity for its motor and controls. Conversely, an electrically heated dryer adds a different electrical load from a similar-looking machine receiving heat from elsewhere.
Electrolux Professional's TD6–30 dryer specification provides a useful manufacturer example: it lists electric, gas and steam heating alternatives, with separate electrical-connection information. This demonstrates why the installed variant matters. It is not a recommendation for that product, proof of local availability or a consumption forecast for your laundry.
The same check belongs at the washing stage. The manufacturer's WN6–35 washer specification distinguishes electric, steam and non-heated variants and separately identifies motor, heating and incoming-hot-water energy in its test data. “Non-heated” does not mean the wider hot-water supply has no energy cost. Trace where that water is heated and who pays for it.
Have your facilities team and laundry-equipment service provider prepare a simple register:
Process or equipment | What to establish | Treatment in the PV-only proposal |
|---|---|---|
Washers and hot-water supply | Exact machine variant, internal electric heating, incoming hot water, steam input and upstream heater or boiler. | Include measured electricity on the eligible account. Leave separately supplied fuel or heat unchanged. |
Tumble dryers | Electric, gas, steam or other installed heating arrangement, plus the electricity for auxiliaries. | Count actual electrical input, not the rated thermal input as though it were grid electricity. |
Ironers, presses and finishing | Heating medium and any central steam supply, alongside motors and controls. | Separate purchased electricity from heat produced or bought elsewhere. |
Site services | Lighting, ventilation, cooling, pumps and other equipment, with the meter supplying each. | Include verified site electricity without assigning the same consumption to several processes. |
This is an information brief, not a request for an owner to open cabinets, inspect burners or alter steam equipment. Use competent specialists and existing equipment records.
Keep electricity, fuel, water and steam on separate lines
Provide a year of DEWA electricity consumption in kWh and the relevant account details. Supply fuel invoices and any purchased-steam or hot-water charges separately. Do not size PV from the combined monetary total, and do not convert a boiler's thermal rating into electrical demand without an assessed process-change design.
Also distinguish water use from the energy used to heat it. PV generation does not itself reduce the litres consumed by the washing process. A proposal promising lower water use needs a separate intervention and a separate calculation.
For a shared building, establish whether the laundry, landlord or a central-services operator pays each account. A roof above your machines is not evidence that its proposed solar connection can offset your bills. The same boundary problem appears in our guide to which electricity and cooling bills rooftop solar can actually reduce.
What Shams Dubai changes, and what it does not
DEWA's Shams Dubai FAQ explains that PV produces electricity for local electrical loads, with surplus exported. Electricity exports and carried-forward credits are deducted from imports before the applicable electricity tariff slabs and fuel surcharges are applied. Standard Shams Dubai does not pay cash for surplus electricity.
That electricity-billing mechanism does not cancel a laundry's separate gas or steam invoice. The DEWA electricity fuel surcharge is part of the electricity calculation; it is not a credit against fuel delivered to your boiler.
Evening production does not automatically disqualify the site: eligible daytime exports can contribute to later electricity-billing offsets. Ask for a monthly model using the actual account, production pattern and likely use of credits, rather than assuming that every forecast unit will be financially useful. This article concerns standard Shams Dubai, not a separate D33 arrangement or another emirate's rules.
Ordinary grid-connected PV is not a promise of uninterrupted washing or steam supply during an outage. DEWA describes protection that stops the PV plant under relevant network conditions. Any continuity requirement needs a separately assessed design.
Compare three scopes without mixing their savings
1. PV with the present laundry equipment retained
Use this as the baseline offer. Keep the current heating arrangement, production requirements and fuel use unchanged. Model PV against measured whole-site electricity, including the electrical auxiliaries of fuel-heated equipment.
Provide interval demand where available, operating days, shift times, representative busy and quiet periods, and known closures. A nameplate helps identify equipment; it does not tell a bidder how long a heater operates or how much electricity a mixed load uses each day.
The building must still pass its physical assessment. Our commercial roof feasibility checklist covers structure, roof condition, openings and access. For a laundry, specifically ask the surveyor to map exhaust outlets and service routes rather than treating the entire roof as available panel space.
2. A separately designed hot-water or heat-recovery project
If a supplier proposes solar thermal, heat recovery or another hot-water measure, request its own process assessment. Which heat demand does it serve, at what temperature and times, with what storage, backup and maintenance? Does it reduce boiler fuel, electric heating or purchased heat?
A domestic solar-water-heater package is not evidence that a commercial laundry's steam or finishing requirement has been met. Keep this work separate from the PV tender until a competent process designer establishes the interface, permissions and achievable benefit. Do not assume SolarQuote's PV comparison includes specialist thermal design.
3. New electric heating or replacement laundry machines, with PV
Treat a change from fuel or steam to electric equipment as a second investment, not an incidental solar saving. Obtain the equipment supplier's written process-capacity, installation, service and warranty requirements, and have the electrical designer assess the new demand and any supply changes.
Compare the replacement plant using grid electricity first. Then calculate how adding PV changes that case. Otherwise a bidder can incorrectly credit the whole avoided boiler-fuel bill to the panels while overlooking the new electricity bill and machinery cost.
Preserve required wash programmes, throughput, textile quality and any customer hygiene obligations. This is not advice to reduce temperatures, change validated cycles or reschedule production merely to chase a higher daytime solar percentage.
Ask for a financial bridge you can check
Require each option to show the annual cost before the project, the annual cost after it, and the reason for every changed line. Keep electricity, boiler fuel, purchased heat, water and service costs distinct.
PV-only: show the electricity bill with and without PV. Hold fuel, purchased heat and water use unchanged unless a separately evidenced intervention changes them.
Process improvement: show its own fuel or heat saving, added electricity, maintenance and required capital or contractual payments.
Combined option: recalculate PV against the demand remaining after the process change, rather than adding two savings estimates made against the original load.
Include surveys, roof work, permissions, connection scope, cleaning, maintenance, replacement allowances, financing and consistent VAT treatment. Allocate shared costs once. Ask bidders to identify assumptions still needing measurement, not hide them inside a single payback number. Our solar quotation line-item checklist helps make the resulting offers comparable.
A commercial-laundry quotation brief
We operate a DEWA-connected commercial laundry in [Dubai location] and have [owner authority or landlord consent status] to assess the roof. We can provide twelve months of electricity bills, available interval demand, operating hours and a machine register identifying electric, gas, steam and incoming-hot-water inputs. Please price rooftop PV with the present heating arrangement as the baseline. Show eligible electricity demand, monthly generation, bill offsets, unused-credit assumptions and whole-life costs. Keep fuel, water and purchased heat unchanged in that case. Price any proposed process or equipment change separately and identify the specialists, permissions and measurements it needs.
Decision takeaway: a commercial laundry should assess solar against the electricity it genuinely buys. A fuel-fired boiler does not rule out PV, but its fuel bill is not a solar-electricity saving. Resolve the heat-source register before accepting the system size or return.
When those records and roof rights are available, request site-specific commercial solar quotations through SolarQuote. Identify the property as a commercial laundry and explain the existing heating arrangement during follow-up. SolarQuote is a comparison and installer-matching platform; suitable proposals depend on project scope and installer availability.
