What to know before buying

Do not clean panels on a hot, sunny day. The listing warns panel surfaces can exceed 65 degrees C. Apply diluted solution, allow it to soak briefly, and rinse fully. The description gives both a 100:1 dilution rate and a 0.5%–1% spray-lance concentration, which are not fully reconciled, so confirm the correct mix and method for your application.

Who is it for?

A good fit for

Owners or maintenance teams cleaning photovoltaic or thermal panels as part of routine upkeep.
Buyers seeking a concentrated liquid cleaner for panels and their frames or seals.

Less suited to

Anyone needing a ready-to-use cleaner or a supplied brush, pole or spray lance.
Anyone who cannot follow the dilution, application and rinse instructions or avoid cleaning in hot direct sun.

Frequently asked questions

Is Solclean ready to use?

No. It is described as a concentrate that should be diluted before use. The listing gives a 100:1 dilution rate and separately states 0.5%–1% for spray-lance use, so confirm the appropriate mixing instruction.

Which panels is it intended for?

The listing describes it for photovoltaic and thermal solar panels, and says it can also be used on frames and seals when applied as directed.

How should it be applied?

The supplied directions describe wetting panels first, applying diluted solution and rinsing. For hand cleaning, agitate with a sponge or brush before rinsing. The listing also says not to clean panels on a hot, sunny day.
