Solar kits are fashionable and there are now more players – which is beneficial for the consumer – long live the competition!
After Sunology, Beem, Sunethic, or more recently Anker SOLIX, today we are focusing on a French manufacturer, the company Sunity, which also offers plug&play solar kits to install yourself on your terrace or on a wall.
The Sunity 425W Double Sided Solar Kit
Like most of its competitors, Sunity offers a large format solar panel with a footprint of approximately 1x2m.
The characteristics are among the best on the market with an efficiency of 21.8% and TOPCon N-Type Monocrystalline cells.
• Trina
• Double-Face Biverre Bifacial Technology
• 144 TOPCon N-Type Monocrystalline half-cells
• Front panel efficiency: 212.7W/m2
• Rear panel gain: between 5% and 30%, i.e. a total power of up to 552W
• 87.4% power guaranteed for 30 years
On the inverter side, Sunity chose a 400W Hoymiles model with peaks up to 540W, which is more than sufficient for this type of panel.
• Todaymiles
• Yield 99.8% MPPT
• Certified IP67 protection rating (Dust and immersion)
• Rated power: 400W
• Module up to 540W
It is possible to connect several kits together, to avoid having to have multiple extension cables. For this, each inverter has several connectors, allowing you to connect up to 4 kits in total.
Connected socket and aluminum structure
The kit obviously comes with an aluminum structure, which can be hung on a wall or placed on a terrace/balcony/garden provided there is enough space.
We have not yet been able to test the installation, but the manufacturer assures that it can be done in less than 10 minutes. The feet are sturdy but everything will have to be ballasted to avoid being caught in the wind. Still plan to be two people for installation, because the pallet weighs more than 30Kg, and the panels are quite heavy to handle alone.
The connection is made in a simple electrical outlet, without the need for an electrician. For monitoring, Sunity is currently using a connected socket, but an in-house solution is already in development. The inverter is therefore not connected directly to your WiFi, which allows the panel to be placed far from the terminals.
5% with our promo code
While waiting for our full test, you can already take advantage of our promo code to get this kit at the best price.
If a kit is often sufficient to cover your consumption bill (see our article), I advise you to take at least 2 panels if you have some heavy equipment such as an air conditioning/heat pump, a swimming pool (pump, PaC) or a large number of devices permanently plugged in (terminals, Starlink etc.), which quickly increases your electrical background noise.
If you have an electric car, you will need to switch to higher powers, at least 2 to 3kWp, or 4/5 panels minimum to have good output during sunny days.
(5% reduction cumulative on the introductory offer, i.e. a final price of €635 instead of €720)
