Side by side

Put any two panels head to head

Pick two modules and the comparison lays their datasheets against each other row by row: power, efficiency, temperature behaviour, degradation, warranty and what each of them costs per watt where prices are published.

Nothing on a comparison is an opinion about a brand. Every figure is the manufacturer's own, and where one of them does not publish a specification the row says so rather than filling the gap.

01

Build a comparison

Start typing a model or a manufacturer in each field and pick from the suggestions. Both slots have to hold a panel before there is anything to open.

Every comparison is built from the two datasheets. Where both panels have published prices in your market, it also works out the cost per watt.

02

Recently compared panels

Comparisons other visitors opened, newest first. The efficiency figures are the front-side ratings from each datasheet; the higher of the two is marked.

A brand comparison weighs two catalogues rather than two modules: what each maker builds, at what efficiency, and how deep the range goes.

What a comparison contains

Both datasheets, row by row

Power, efficiency, temperature coefficient, degradation, dimensions, weight and both warranty terms, each pair on one line with the difference between them stated rather than left to be read off.

Prices where they exist

When both modules have offers in your market the comparison works out the cost per watt from them. Where only one does, it says so instead of comparing a price with nothing.

A written verdict

Each comparison carries a short summary of what actually separates the two panels, generated from the same figures the table shows and regenerated when either datasheet changes.
