Price per panel advised by the manufacturer. Many brands didn't supply pricing but we'll update these when we can. Actual prices can vary significantly between suppliers - you need to compare costs of whole systems and installation, not just the panels.
enter value/s in increments of 1 between 0 and 396
Claimed nominal power (W)
The nominal power output for the panel under standard lab conditions. The higher the number, the more electricity you'll get from the panel. See our solar panels buying guide for an explanation.

AC or DC
Most panels are DC - they deliver high-voltage direct current (DC) to the inverter, which converts it to alternating current (AC) for your home's circuits. Some panels are classed as AC, as they come with a microinverter on each panel. See our solar panels buying guide for the pros and cons of each type.
Performance warranty (years)
The number of years for which a certain level of performance is guaranteed (typically warranting that the panel will still produce at least 80% of its claimed power rating at the end of this period and will degrade in a predictable linear fashion). See our solar panels buying guide for more information.
