PanelWash

The Problem

Malaysia installed 4.2GW of solar capacity and it's growing 30% YoY, but nobody talks about maintenance. Dirty solar panels lose 15-25% efficiency. After 6 months of Malaysian weather (dust, bird droppings, haze), a RM25K solar installation is underperforming by RM500+/year in lost electricity savings. There is no specialized solar panel cleaning service in Malaysia — only general cleaners who use dish soap and hard water, which damages panels and voids warranties.

The Solution

AI-optimized solar panel cleaning subscription. IoT sensors monitor panel efficiency drop → auto-schedule cleaning when output falls below threshold. Trained technicians use deionized water and soft-bristle equipment per manufacturer specs. Quarterly cleaning subscription (RM199/visit for residential, RM599/visit for commercial). Dashboard shows ROI: cleaning cost vs recovered electricity savings.

Target Market

180,000+ residential solar installations and 12,000+ commercial solar sites in Peninsula Malaysia

Revenue Model

Subscription: RM199/quarter (residential), RM599/quarter (commercial up to 50kW), enterprise custom. Add-on: solar health inspection report RM99/year.

4-Week Validation Plan

• Week1: Interview 15 solar panel owners about their cleaning routine and whether they've noticed efficiency drops.
• Week2: Clean 10 solar installations for free. Measure before/after output with owners' inverter data.
• Week3: Calculate average efficiency gain and savings. Survey willingness to subscribe at RM199/quarter.
• Week4: Analyze: >12% avg efficiency gain AND >40% subscription interest = commit; <8% gain = pivot to general solar maintenance education.
