Answers to the questions we hear most about solar installation, net metering, maintenance and more.
Most residential installations are completed within 3-5 working days once materials are on-site. Commercial and industrial projects vary by scale, typically ranging from 2 to 8 weeks depending on system size and site complexity.
For net metering, your DISCO will replace your existing meter with a bi-directional (net) meter as part of the official net metering process, which VOX Energy manages on your behalf.
On-grid systems connect directly to the utility grid and support net metering but have no backup power. Off-grid systems are fully independent with battery storage, ideal for locations without grid access. Hybrid systems combine both — grid connection with battery backup — offering net metering plus power during outages.
Your bi-directional meter tracks both the electricity you import from the grid and the electricity you export back to it. At the end of each billing cycle, any surplus exported units are generally credited against your consumption, as per your DISCO's current net metering policy.
Yes. Hybrid systems use battery storage and a smart inverter to automatically switch to backup power during a grid outage, keeping selected critical appliances running.
This depends entirely on your battery capacity and connected load. VOX Energy sizes your battery bank based on how many hours of backup you need and which appliances must remain powered.
Routine maintenance includes periodic panel cleaning, visual and electrical inspection, and inverter diagnostics. VOX Energy offers Annual Maintenance Contracts (AMC) covering all of this on a scheduled basis.
In dusty environments, cleaning every 1-3 months is recommended to prevent generation losses from soiling. VOX Energy's solar washing service offers scheduled cleaning plans tailored to your location.
Carbon credits represent verified reductions in CO₂ emissions, often tradeable in voluntary carbon markets. Eligibility depends on system scale, verification standard requirements, and market conditions — VOX Energy's carbon credit consultancy can assess your project's feasibility.
We supply Tier-1 panels with manufacturer warranties typically covering 12 years on product defects and 25-30 years on power output performance. Exact terms vary by panel model and are provided with every quotation.
Inverter warranties vary by brand and model, typically ranging from 5 to 10 years, with extended warranty options available at the time of purchase.
Savings depend on your current electricity consumption, tariff slab, roof space and chosen system size. Use our Solar Savings Calculator for a personalized estimate, or request a free consultation for a detailed assessment.
Most residential and commercial systems in Pakistan achieve payback within 3 to 6 years, after which the system continues generating essentially free electricity for its remaining lifespan.
Most flat and sloped concrete or metal roofs are suitable. Our team conducts a free site assessment to evaluate roof orientation, shading, structural load capacity and available area before finalizing your system design.
Yes, panels still generate power on cloudy days, though at reduced output compared to direct sunlight. System sizing accounts for average irradiance across the year, not just peak sunny days.
In many cases, yes — particularly with on-grid and hybrid systems where inverter capacity allows for expansion. We recommend discussing future capacity needs during initial system design.
On-grid systems automatically shut down during a grid outage for safety (anti-islanding protection) and resume once grid power is restored. Hybrid and off-grid systems can continue operating using battery power.
VOX Energy can guide clients through available bank financing, leasing and installment options offered by various financial institutions for solar installations.
Typically this includes CNIC, latest electricity bill, proof of property ownership or consent, and technical system specifications. VOX Energy prepares and files this documentation on your behalf.
Yes, VOX Energy provides EPC solar services throughout Pakistan, including major cities such as Karachi, Islamabad, Faisalabad, Multan and beyond.
