  1. Cost Breakdown for a Mobile Solar System Rental
    • Total cost to set up a mobile solar system:
      • Mobile solar panels: R20,000
      • Inverter: R10,000
      • Batteries: R30,000
      • Charge controllers: R2,000

      • Monitoring system: R3,000
      • Labor and installation equipment: R5,000
    • Total cost: R82,000
  2. Revenue and Profit Calculation
    • Charging R5,000 per day for renting the mobile solar system.
    • Revenue: R5,000 per day
    • Assuming rental 20 days per month: R5,000 x 20 = R100,000
    • Monthly profit: R100,000 – (monthly operating expenses + initial setup cost depreciation) = Profit
  3. Daily Production and Profit
    • Daily revenue: R5,000
    • Monthly operating expenses (including maintenance, staff, etc.): R20,000
    • Depreciation of initial setup cost (over 12 months): R82,000 / 12 ≈ R6,833
    • Monthly profit: R100,000 – R20,000 – R6,833 = R73,167
    • Daily profit: R73,167 / 30 ≈ R2,439

By renting out the mobile solar system for 20 days per month at R5,000 per day, you can achieve a monthly profit of R73,167, resulting in a daily profit of approximately R2,439.
