The Renogy 200W ShadowFlux Anti-Shading N-Type is a single rigid solar panel for motorhomes, sheds, campervans, caravans and boats, and it sits at number 7 in this guide. It is the one panel here where the headline number holds up: the title says 200W and the specification field says "Maximum Power: 200 Watts". In a guide where a "200W" kit lists 100W in its spec table and a "390W" kit lists 340W, that agreement is worth pointing out.

The catch is what that honesty costs. At £194.99 for a 200W panel, the Renogy works out at roughly 98p per watt — the top of the range here, where the cheapest panel in the guide works out at 41p. Two other things on the listing are worth reading twice: the specification table gives efficiency as "21-25%" while a bullet claims 25% efficiency, and a bullet describes the panel as "7% smaller and 10% more compact than PERC solar panels", which are two different numbers attached to what sounds like the same measurement. The star breakdown shown on the page also adds up to 100 ratings, while the figure beside the 4.6 score says 20. Everything on this page is taken from the Amazon listing, not from any test of our own.

## Questions people ask

**How much does the Renogy 200W ShadowFlux cost per watt?**

The listing price is £194.99 against a listed maximum power of 200 Watts, which works out at roughly 98p per watt.

**Does the Renogy 200W ShadowFlux really produce 200W?**

The listing's specification field says "Maximum Power: 200 Watts" and the title says 200W, so the two agree. What it produces in practice is not something we tested; one reviewer reports about 46W on a heavily cloudy, rainy day.

**What efficiency does the Renogy 200W ShadowFlux have?**

The specification table lists 21-25%, while the bullet text says the N-Type cells with 16BB technology achieve 25% efficiency. Both figures come from the same Amazon listing.

**How big and heavy is the Renogy 200W ShadowFlux panel?**

The listing gives 126.2 x 76.4 x 3 cm and 10.8 kg, and states the panel is 7% smaller and 10% more compact than PERC solar panels.

**What warranty comes with the Renogy 200W ShadowFlux?**

Five years on materials and craftsmanship, plus a 25-year output guarantee that the panel will still deliver 80% of its power.

**Does the Renogy 200W ShadowFlux work in shade?**

Renogy's ShadowFlux anti-shading technology is described on the listing as enhancing power generation in shaded areas caused by buildings, plants or stains, and reducing hot-spot risks. That is the manufacturer's description, not a result we measured.
