Frequently Asked Questions
Will the installation disrupt our daily operations?
No. Most of the work happens on the roof or in the electrical room. Any necessary power shutdowns (for final grid interconnection) are scheduled during off-hours, weekends, or planned maintenance windows to ensure zero impact on production.
What happens during a grid power outage?
Standard grid-tied solar systems shut down during an outage for safety (to prevent “islanding”). However, if we integrate a Battery Energy Storage System (BESS) or a microgrid controller, your facility can continue to operate essential loads even when the grid is down.
How much maintenance is required?
C&I systems are relatively low-maintenance but not “no-maintenance.” We recommend:
- Annual Cleaning: Especially in industrial areas with high dust or debris.
- Thermal Imaging: Yearly drone or handheld infrared scans to detect “hot spots” or failing cells.
- Electrical Testing: Periodic torque checks and inverter health diagnostics.
Can you handle large-scale electrical upgrades beyond solar?
Yes. As a full-service electrical firm, we specialize in:
- Switchgear Upgrades: Modernizing your main distribution boards.
- Power Factor Correction: Reducing “reactive power” penalties on your utility bill.
- EV Charging Infrastructure: Designing and installing fleet or employee charging stations.
10. How long does a typical project take from start to finish?
The timeline generally looks like this:
- Feasibility & Design: 2–4 weeks.
- Permitting & Utility Interconnection Approval: 2–4 months (highly dependent on local authorities).
- Procurement & Construction: 1–3 months.
- Commissioning & Permission to Operate (PTO): 2 weeks.
