About Big Dave Solar and Tech Ltd
A Nigerian solar company built on honest sizing, clean installation and support that does not disappear after payment.
Who we are
Solar installers you can message directly
Big Dave Solar and Tech designs and installs solar panels, hybrid inverters and lithium batteries for homes and businesses. We started with a simple frustration: too many Nigerians pay for oversized systems, mixed-up equipment or installations that nobody comes back to fix.
So we do it differently. You talk to Big Dave directly on WhatsApp, we survey your property, we size the system to what you really use, and we put every cost on paper. When the work is done we test it, explain it and stay available.
We are a registered company, based in Asaba and Owerri, serving homes, shops, offices, clinics and small factories.
What we believe
Four promises we build every job around
Honest sizing
We design the smallest system that runs what you actually use, with room to grow. We do not upsell kVA you will never need.
Itemised quotes
Every panel, inverter, battery, cable and breaker is listed with its price, so you can compare us with anyone.
Safe, neat work
Proper earthing, surge protection, clean cable runs and labelled breakers. Solar done right is invisible and safe.
Support after payment
We commission, explain and stay reachable on WhatsApp. If something trips at night, you can message us.
