Q :
7. Is 150 kWh per day a lot?
A :
For business energy users, 150 kWh per day represents a moderate-to-high consumption level, depending on facility type and operational hours.
Residential context: Roughly five times higher than the average U.S. household’s daily use (~30 kWh/day).
Small commercial operations: This is equivalent to a continuous power demand of approximately 6.25 kW. This aligns with energy use for a small office (5–10 employees) with HVAC, computers, and lighting running 8–10 hours daily.
Light industrial or retail facilities: 150 kWh/day is typical for sites with limited machinery or single-shift operations.
Large industrial facilities: Considered low, likely powering a single production line or subsystem.
At this consumption level, companies can benefit from solar or battery integration. A 30–40 kW solar system could offset roughly 150 kWh/day in locations with 4–5 peak sun hours, reducing grid dependency and improving cost stability.
Q :
8. How long will a 100 kWh solar battery system last for my business?
A :
The runtime of a 100 kWh commercial solar battery system depends on your facility's power consumption. The estimation methods are as follows:
Power Consumption and Runtime
10 kW consumption: 100 kWh ÷ 10 kW = 10 hours
50 kW consumption: 100 kWh ÷ 50 kW = 2 hours
100 kW electricity consumption: 100 kWh ÷ 100 kW = 1 hourHow long is the lifespan of a 100 kWh solar battery system?
Lithium iron phosphate (LiFePO₄) batteries are commonly used in solar systems and typically have a lifespan of 15 to 20 years, which is equivalent to 6,000 to 10,000 charge-discharge cycles.
How can a 100 kWh system be scaled to meet commercial electricity demands?
Most commercial battery systems have a modular design that allows the capacity to be increased by connecting several units in parallel. Some systems can support up to five units in parallel, providing a total capacity of 500 kWh. This configuration is ideal for high-end applications such as shopping malls, office buildings, hotels and electric vehicle charging stations.
Cost and ROI considerations for a 100 kWh solar battery system
The cost of a 100 kWh battery system varies depending on the type, manufacturer and configuration of features. As of 2024, the average cost of lithium-ion battery packs is around $140 (£110) per kWh, meaning a 100 kWh system would cost approximately $14,000 (£11,000).
Solar battery systems deliver significant savings by reducing peak demand charges and enhancing energy efficiency. Some enterprises, have achieved a return on investment of up to 30% through optimised energy storage and consumption management.
What performance metrics should I consider?
Implementing solar photovoltaic systems can significantly reduce peak demand charges and enhance energy efficiency, achieving substantial cost savings. Some enterprises have achieved a return on investment of up to 30% by optimising energy storage and usage.
Consider the following performance metrics:
Efficiency: Select systems with high conversion efficiency to minimize energy loss.
Peak Power Handling Capacity: Ensure the system can withstand short-term power surges without compromising performance.
Environmental Adaptability: Select systems with appropriate protection ratings and temperature tolerance to suit the facility's environmental conditions.What certifications and warranty terms does Sunpal offer?
