Common Questions

Frequently Asked Questions

Is solar suitable for every property?
Most properties can benefit from solar energy, although the system size and expected savings will depend on roof space, electricity usage and site conditions.
What is the difference between grid-tied, hybrid and off-grid systems?
A grid-tied system works alongside the utility grid. A hybrid system combines solar panels with battery storage, while an off-grid system operates independently without relying on the utility grid.
Do I need battery storage?
Not necessarily. Battery storage is recommended when backup power or energy independence is important, but many customers begin with rooftop solar and add batteries later.
How long do solar panels last?
Most quality solar panels are designed to operate for 25 years or more with proper installation and maintenance.
Can I monitor my solar system remotely?
Yes. Many modern systems provide mobile apps or web portals for monitoring solar generation, battery status and system performance.
Do you provide maintenance services?
Yes. We provide inspections, preventive maintenance, troubleshooting and system performance assessments.
Can you upgrade an existing solar system?
Yes. We can assess your current system and recommend suitable upgrades, including additional panels, battery storage or inverter replacement.
