1. How much does a solar installation cost in Nigeria?

The cost depends on your system size, which is determined by your energy consumption and the appliances you need to power.

2. How long does a solar installation take?

Most residential solar installations are completed within one to three days. This covers panel mounting, inverter and battery installation, cabling, earthing, and final commissioning. Commercial installations vary depending on system size but typically takes several days. We confirm the expected timeline during the consultation and after the assessment.

3. What is the lifespan of a solar system installed by Alexoll?

The Tier-1 solar panels we install carry a 25-year performance warranty, retaining at least 80% of their rated output after that period. Quality hybrid inverters last 5 years and above with proper maintenance. Battery lifespan depends on the type — lithium-ion batteries last 8 to 15 years, while tubular lead-acid batteries last 3 to 5 years.

4. Does solar work during epileptic power supply outages and at night?

Yes. During the day, your solar panels generate power directly. Excess generation charges your battery bank. While at night, your inverter automatically switches to battery power with no interruption. We size the battery bank to cover your essential loads through a typical overnight period so your home or business continues operating uninterrupted regardless of what the grid is doing.

5. Do you provide after-sales support and maintenance?

Yes, our service team remains available after every installation for scheduled maintenance, emergency repairs, performance checks, and system upgrades. We offer annual maintenance contracts for both residential and commercial clients that cover panel cleaning, inverter health checks, battery testing, and priority call-out response.
