FAQ: 500kW Solar System for Supermarket in Papua New Guinea
❓1. What is a 500kW solar system used for in supermarkets?
A 500kW solar system is designed for large commercial facilities with high energy demand. It can support equipment such as air conditioning, refrigeration systems, lighting, and escalators.
❓2. Is a 500kW solar system enough for a supermarket?
Yes, a 500kW system is suitable for large supermarkets with heavy electricity loads, especially those operating central cooling systems and multiple electrical devices.
❓3. How much does a 500kW solar system cost?
The cost depends on system configuration, especially battery storage capacity. Systems with large battery storage (like 1MWh) have higher upfront costs but deliver faster ROI and greater energy independence.
❓4. Why is battery storage important in a supermarket solar system?
Battery storage allows excess solar energy generated during the day to be used at night, ensuring continuous operation and reducing reliance on the grid.
❓5. What is the ROI of a 500kW solar system?
Most systems achieve ROI within 2–3 years, depending on electricity prices and system usage. In this project, ROI was achieved in just 2 years.
❓6. Can solar systems ensure stable power for supermarkets?
Yes. Hybrid solar systems provide 24-hour stable electricity, even in areas with unreliable grid power.
❓7. How much electricity can a 500kW system generate daily?
A 500kW system can typically generate 2000–2500 kWh per day, depending on sunlight conditions.
❓8. How long does installation take?
The full project timeline usually takes 2–3 months, including design, production, shipping, and installation.
