290W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
290W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
A 43.2 V open-circuit voltage moves this module into 24 V territory, which roughly halves the current versus an equivalent 12 V panel and lets you run thinner cable over longer distances. It suits arrays where the controller sits well away from the roof.

Where it fits best
- 24 V off-grid systems for a small home or shop
- Arrays where the controller and battery sit 15 m or more from the panels
- Grid-tie strings feeding a higher-voltage MPPT input
Questions buyers ask
Can I use this on a 12 V system?
Only with an MPPT controller that accepts the higher input voltage. A PWM controller would waste most of the module's power, so MPPT is strongly recommended here.
How does 24 V help my installation?
Lower current means less voltage drop and smaller cable sizes, which usually pays for itself on runs beyond about 10 m.

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.
