340W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
340W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
Nearing 49 V open-circuit, the 340 W module works well in longer series strings, where holding current at 8.83 A lets installers use standard 4 mm² cable across the whole array without special provisions.

Questions buyers ask
How does this fit a 48 V system?
Strings of two or more reach the voltage a 48 V MPPT expects comfortably, while the modest current keeps losses and cable costs low.
What about hot-climate performance?
The -0.350 %/°C power temperature coefficient is typical for monocrystalline modules. In hot climates, allow for reduced peak output and favour mounting that lets air move beneath the panel.

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.
