Common questions from laundry business owners about solar energy
Commercial laundry equipment is among the most energy-intensive in any business. A single industrial dryer (20–30 kg capacity) draws 10–15 kW continuously, while a commercial washer uses 3–7 kW per cycle plus hot water heating. A typical coin laundry with 10 washers and 8 dryers running simultaneously consumes 80–120 kW at peak — equivalent to a small factory floor. Multiply this by 12–16 operating hours daily, and a mid-size laundromat easily racks up RM 5,000–12,000 per month in TNB bills before solar.
A typical coin laundry with 8–12 machines (combined load 40–80 kW) needs a 30–60 kWp solar system costing RM 105K–210K, delivering monthly savings of RM 3,500–6,500. Under Solar ATAP, excess solar generation during quieter midday periods earns credits to offset peak morning and evening usage. We recommend sizing the solar system to cover 70–80% of your average daytime load — not the peak — to maximise the value of every ringgit invested. Our free remote review includes a load-profile analysis based on your actual TNB bills.
Solar thermal is highly effective for laundries, where hot water for wash cycles accounts for 20–30% of total energy costs. A solar thermal system costs RM 15,000–40,000 and can supply 60–80°C water for industrial washers, reducing electric water heating costs by 65–80%. Many of our laundry clients install a hybrid system: solar PV panels for all electrical loads (dryers, lighting, AC) plus solar thermal collectors for hot water. The combined system achieves 75–85% total energy cost reduction — the best ROI of any commercial solar solution.
Laundries have the fastest solar payback among all commercial businesses — typically 1.5–2.5 years — because energy costs are so high relative to revenue. For a mid-size laundromat spending RM 8,000/month on electricity: a 60 kWp system at RM 210,000 saves RM 6,200/month, paying back in 34 months. After payback, you keep RM 6,200/month — RM 74,400/year — for the remaining 22+ years of system life. Total 25-year savings: RM 1.86 million on a RM 210,000 investment. GITA tax incentives further reduce the effective cost to around RM 147,000.
Commercial washers are significantly more energy-intensive than household units. A standard household washer uses 0.5–1.5 kWh per cycle. A commercial front-loader (15–25 kg capacity) uses 3–8 kWh per cycle including water heating, running 6–10 cycles per day. At TNB's commercial tariff of RM 0.435/kWh (C1 tariff), a single commercial washer costs RM 8–17 per day to operate — RM 240–510 per month per machine. With solar, this cost drops to near zero during daytime hours, dramatically improving the economics of each wash cycle.
