Off-Grid Solar Systems
Off-grid systems operate completely independently of the utility network, using solar panels and batteries (and sometimes a generator) to power a site around the clock.
How it works
- Panels charge a battery bank through a charge controller or inverter-charger.
- The inverter supplies AC power to the site from the batteries and solar.
- Sizing accounts for days of low sunlight and nighttime use.
- An optional generator can provide additional backup.
Where it is used
- Remote farms and homes
- Telecom and monitoring sites
- Construction camps
- Areas with no or very unreliable grid
Benefits
- Independence from the grid
- Power in remote locations
- Scalable with load growth
- Low running costs compared with fuel
Things to consider
- Careful load management, because there is no grid to fall back on
- Battery sizing and lifespan
- Seasonal variation in sunlight
- Higher system cost due to storage
Our engineering approach
- Detailed daily energy budget
- Autonomy and battery bank design
- Protection, earthing and cable design for remote sites
- Maintenance plan and operator guidance
Frequently asked questions
How do I know the system is big enough?
We build an energy budget from your loads and design with margin for weather, so the system matches how you really use power.
Can I connect to the grid later?
Often yes. Planning for this at the design stage keeps options open.
