Frequently Asked Questions

Yes, though in most commercial applications (such as hotels, condominiums) the autonomy of your system would be 96-98% yearly based. Few consecutive rainy days might require injecting additional power from Utility or Generator for specific time of day/night.

Absolutely yes. Properly engineered/designed C&I (Commercial & Industry) solar system with BESS (Battery Energy Storage System) can fully make hotels, resorts, restaurants, offices, residences, factories, hospitals, schools OFF-GRID. Large installations require detailed load and power quality analysis and professional electrical engineering.

As during night time there is no solar irradiance, solar panels do not produce electricity. A system equipped with BESS (Battery Energy Storage System) can use energy stored during the day to supply electricity thought whole night for your property.

Yes. Solar modules or panels continue producing electricity, although production is lower during heavy cloud cover. Thus, Solar Leader provides its clients with panels featuring most advanced technology which provides better low-light response, higher cell efficiency (up to 23.8%) and better temperature coefficient.

If the system includes properly configured BESS and a hybrid inverter, the client will not notice grid outage.

High-Quality Lithium Iron Phosphate (LiFePo4) battery systems from Tier-1 manufacturers can be 100% safe if equipped with BMS (Battery Management System), suppliers/manufacturers are certified, systems correctly designed, professionally installed and adequately protected.

Solar systems generally require relatively little or NO maintenance. Panels may need periodic cleaning, while electrical connections, protection devices, batteries, inverters, monitoring systems, and mounting structures should be inspected periodically.

There is no universal payback period. However, taking into consideration frequent using of generators for long hours, maintenance of generators with high electricity bills hotels and resorts incur, in most cases ROI is between 15 and 30 months.

For Commercial & Industrial we do analyze historical electricity consumption, through bills and temporarily connecting our Power Quality Analyzer to determine power peaks, energy demand, critical load. At last, future expansion, and the client’s required level of energy independence will be taken into consideration.

Yes, provided the system is designed for their running power and starting (inrush) currents. Large motors and HVAC equipment require particular attention during system design.

Yes! A modular design can allow additional panels, batteries, or inverter capacity to be added later, provided future expansion is considered during the original engineering stage.

Yes. Solar inverters, batteries, grid electricity, and generators can be integrated into one energy-management system. This can substantially reduce or totally annul generator operating hours and fuel consumption.

A solar installation involves significant DC and AC voltages, high electrical currents, batteries, protection systems, and structural requirements. Proper engineering is essential for safety, reliability, equipment lifespan, performance, and regulatory compliance.

The difference is not simply the brand of panels, batteries or inverters. A professional system considers load analysis, equipment compatibility, cable sizing, protection, earthing, surge protection, battery management, ventilation, structural integrity, monitoring, commissioning, documentation, and after-sales support.

Definitely not. For many businesses, particularly hotels, condominiums and resorts, solar is also about energy security, operational continuity, visitors’ satisfaction, business sustainability and resilience, low environmental footprint, eliminating generator noise and pollution, predictable energy costs, and a more comfortable experience for customers and staff.

Solar power is more than an investment in lower electricity bills. It is an investment in energy independence, business resilience and a sustainable future.
