PatioSun sells a family of four kits, from the Lite to the Max. Only the Lite has its panel size on the page we could read. Here is what we can say for each, and where we are leaving a gap rather than guessing.
What do you get in the box?
The Lite has one 445 W bifacial N-type TOPCon panel, which means it can catch light on both sides. It has a Hoymiles HiFlow 800 W microinverter rated IP67, which means dust-tight and waterproof for outdoors. A steel ground stand is included. The cable is 5 m with a UK three-pin plug and a 5 A fuse. We have not tested it. This is what the seller says. The panel sizes of the PLUS, Duo and Max are not in our notes, so check the listing.
How much does it cost?
The Lite is £449. The Lite PLUS is £470. The Duo is £699. The Max is £749. Price checked 12 October 2026. The price includes 20% VAT, because a kit you fit yourself is standard-rated. The kits are made to order and the seller quotes 10 to 14 days for delivery. So you will not get it tomorrow.
How much will it save a year?
The government says 800 W of panels saves about £70 to £110 a year. The Lite is 445 W, so we scale it: 445 ÷ 800 × £70 to £110 comes to about £40 to £60 a year. For the Duo, we have assumed it is a two-panel kit that gets the full £70 to £110, because the inverter caps output at 800 VA. Check the listing. We have not worked out the PLUS or Max. These are our estimates, scaled from the government's 800 W figures.
How long does it take to pay for itself?
Divide the price by the saving. Lite: £449 ÷ £60 = about 7.5 years, and £449 ÷ £40 = about 11 years. Duo: £699 ÷ £110 = about 6.5 years, and £699 ÷ £70 = about 10 years. The Duo's top end is a long wait. Read is plug-in solar worth it? for the full method.
Is it on the ENA register?
PatioSun says the kit is "approved by ENA Connect as being compliant to the latest plug in solar regulations and recommendations". It also says you must register the kit online with your local network operator. These are the seller's words. We have not checked them. Search the exact model on the ENA register yourself before you buy. Our DNO guide covers the notification.
Where can you put it?
A steel ground stand comes in the box. That suits a patio, a lawn or a flat bit of garden. You do not need to drill into a wall. If you want it on a shed, fence or flat roof, read our guide to those spots. Face it south, tilted up, for the most power.
Does the warranty outlast the payback?
PatioSun lists a 10-year product warranty and a 10-year inverter warranty. It also lists 25-year panel performance, meaning the panel should still make a set share of its power after 25 years. Our rule is that the warranty should be longer than the payback. The Lite pays back in 7.5 to 11 years, so 10 years covers the early end but not the late end. The Duo, at 6.5 to 10 years, just about fits. The 25-year panel promise is the strongest part.
Who is it for, and who should skip it?
The Lite suits someone who wants a cheap kit with a stand included and can wait two weeks. Skip it if you are in a hurry, or if you need to know the PLUS, Duo or Max wattage before you pay. We could not confirm it, so ask the seller. The Duo is the better value per watt if it is a two-panel kit.
The quick version
- The Lite is 445 W at £449 with a ground stand. The Duo is £699.
- We estimate payback at 7.5 to 11 years for the Lite and 6.5 to 10 for the Duo, if as we assume it is a two-panel kit.
- Check the listing for PLUS, Duo and Max wattage. Delivery is 10 to 14 days.
