1. Choosing Your Solar System
What is the difference between On-Grid, Off-Grid, and Hybrid systems?
- On-Grid (Grid-Tied): Best for reducing monthly bills. It exports surplus electricity back to the grid via net metering but shuts down during load shedding/power outages for safety.
- Hybrid: The best of both worlds. It operates like an on-grid system to save money but includes a battery backup bank to keep your critical appliances running during power cuts.
- Off-Grid: Completely independent of the utility grid. It relies entirely on solar panels and batteries, typically suited for remote areas without grid access.
How do I know what size system (e.g., 5kW, 10kW, 15kW) my home or business needs?
System size depends on your average monthly electricity consumption in units (kWh) and your peak load.
- 5kW to 10kW: Ideal for average 3 to 5-bedroom homes running inverter ACs and regular household appliances.
- 10kW to 20kW+: Suited for larger homes or small offices with heavy daytime loads.
- Industrial Scale: Customized based on factory machinery power requirements.
We offer a free on-site engineering evaluation to calculate your exact load requirements and recommend the perfect tier-1 configuration.
2. Net Metering & Financials
How does Net Metering work in Pakistan?
Net metering allows you to feed your excess solar energy back into the national grid. Your bidirectional meter records both the energy you import (buy) and export (sell). At the end of the billing cycle, you are only charged for the “net” energy used. If you export more than you import, you get credits that roll over to lower future bills.
Does Zelix Voltaic handle the net metering process?
Yes, we provide end-to-end net metering management. Our team handles the preparation of documents, structural stability certificates, processing with your local distribution company (such as LESCO, K-Electric, FESCO, etc.), and physical installation of the green meter.
What is the average payback period for a solar system?
On average, a high-efficiency tier-1 solar installation pays for itself within 3 to 4 years. With solar panels rated for 25+ years of performance, this translates to over 20 years of free electricity after your initial investment is recovered.
3. Technology & Installation
What solar brands and components do you use?
We build all setups using only premium Tier-1 solar panels (such as Jinko, Longi, or Canadian Solar) paired with high-efficiency smart inverters (such as Solis, Growatt, or Huawei) to ensure maximum uptime and system longevity.
How long does the physical installation take?
Once the site design is approved, a standard residential installation takes 2 to 4 days. Commercial and industrial setups vary based on structural complexity and capacity size.
Will my solar panels still work on cloudy or rainy days?
Yes. Solar panels generate power from light, not heat. While production will drop during overcast or rainy conditions (generating about 10% to 25% of their typical capacity), they still function. Generation returns to peak capacity as soon as the clouds clear.
4. Support & Maintenance
How often do solar panels need to be cleaned?
To maintain maximum efficiency, panels should be cleaned every 2 to 4 weeks, especially during dry, dusty seasons or when there is heavy smog. Accumulated dust can reduce output by up to 15% to 20%.
What warranties do you offer?
We stand by our engineering work. Typical industry-standard warranties on our setups include:
- Solar Panels: 25-year linear power output warranty.
- Inverters: 5 to 10-year manufacturer warranty.
- Workmanship: Comprehensive structural and installation warranty.
