How solar and battery storage can reduce generator dependence

In sectors like construction, events and remote site operations, power is often supplied by diesel generators due to a lack of mains access. While generators are a reliable source of power, combining them with solar and a battery storage unit can reduce fuel consumption, lower emissions and improve overall efficiency.

How does a hybrid solution work?

  • Solar panels generate free, renewable energy during daylight hours.
  • BSU’s store any excess solar power for use when the sun goes down or when demand spikes.
  • Generators act as a backup, only kicking in when stored or solar energy isn’t enough.

This setup allows the generator to run less frequently and more efficiently, while solar and battery systems handle the bulk of the load during normal operation.

Key Benefits of a hybrid solution

Significant fuel savings
By reducing the generator’s runtime, you burn less diesel, resulting in lower fuel costs and reduced on-site refuelling.

Lower carbon emissions
Hybrid systems drastically cut your environmental impact. Using solar and stored energy instead of diesel helps you meet sustainability targets and reduces noise pollution on site.

Better generator efficiency & lifespan
Running a generator at variable or low loads isn’t always the most efficient use of its capacity. By introducing a Battery Storage Unit to handle load fluctuations, the generator operates at its optimal performance range, supporting its efficiency and helping to maximise its lifespan.

24/7 reliable power
The system ensures constant power availability. If solar and battery levels are low, the generator automatically starts, ensuring your operations never miss a beat.
