220W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
220W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
With a 21.6 V open-circuit voltage and 12.96 A of short-circuit current, this module is built to deliver high current into a 12 V bank rather than high voltage into a string — a good fit for off-grid sites that prioritise battery charging over long cable runs.
Where it fits best
- Off-grid homes running pumps and refrigeration
- Replacing a pair of 100 W panels with one unit and less wiring
- Solar water pumping for smallholder irrigation
Questions buyers ask
Why is the current so high for this size?
The cell layout favours current over voltage, which charges a 12 V bank efficiently through an MPPT controller but means you should keep cable runs short to limit voltage drop.
What cable size should I run?
For a typical 3-5 m run at this current, 4 mm² solar cable keeps losses acceptable. Longer runs should step up to 6 mm².

Frequently Asked Questions
What is a monocrystalline solar panel?
A panel built from single-crystal silicon cells, giving higher efficiency and a smaller footprint than polycrystalline types.
Do panels work on cloudy days?
Yes, at reduced output — typically 10–50% of clear-sky levels depending on how thick the cloud cover is.
How long do solar panels last?
Quality modules commonly retain most of their output for 20–25 years thanks to tempered glass and aluminium frames.
Can I connect panels to a battery?
Panels feed an MPPT charge controller or hybrid inverter, which safely charges the connected battery bank.
