Solar used to mean a roof installation, scaffolding and a long wait. Today, solar panel kits for home use make it much easier to start generating your own electricity. This guide covers what a kit includes, how to choose the right size and what to check before you buy.
What's in a plug-in solar kit
A plug-in solar kit is a ready-to-use bundle. It typically includes:
-
Solar panels that collect sunlight.
-
A microinverter that converts the panel's power into the electricity your home uses.
-
Cabling and connectors to join everything together.
The power feeds into your home's circuit, so whatever is running at the time uses solar first. If you'd like the detail, read our guide on how plug-in solar panels work.
Who plug-in solar panels suit
Plug-in solar panels in the UK suit people who want to cut their bills without a full rooftop system. They're a good match if you have:
-
A garden, patio or outdoor space with good sun.
-
A flat roof.
-
A smaller budget or a wish to start small.
-
A home where a traditional installation isn't practical.
Choose the right size
Size is the biggest decision when comparing solar panel kits for home use.
Solarfy Solo 455 W: a single-panel kit and an easy first step into solar. Choose it if you have limited space or want to try solar before expanding.
Solarfy Duo 910 W: twice the output of the Solo. Choose it if you have the space and want to generate more.
Both kits are ENA registered and suited to gardens and flat roofs. See the Solo 455 W and Duo 910 W product pages for full details.
Where to place your panels
Placement affects how much power you get. Look for:
-
Direct sunlight for as much of the day as possible.
-
Little or no shade from walls, trees or fences.
-
A safe, secure position where the panels won't be knocked or blown over.
What to check before you buy
-
Certification: look for ENA registration, which relates to connecting to the UK grid.
-
Complete kit: make sure the panels, inverter and cables are designed to work together.
-
Warranty and support: know what the supplier covers.
-
Delivery and returns: check the terms, including any return window.
-
Your own usage: think about when you're home and what you run during the day.
Get the most from your kit
You don't need a battery to benefit from solar. Use appliances such as the washing machine and dishwasher during the day, and use timers or smart plugs to start them when your panels are producing.
Frequently asked questions
1. How long do solar panels last?
Many panels are designed to last for decades. Check the warranty for the specific kit.
2. Do solar panels need much maintenance?
Very little. An occasional clean and a check that nothing is shading them is usually enough.
3. Can I start small and add more later?
Often yes, for example by starting with the Solo and moving up to the Duo. Confirm compatibility with the supplier first.
The bottom line
The right kit depends on your space, your usage and your budget. Start with the size that fits your home, place it well and use the power as it's generated. Ready to choose? Browse our plug-in solar kits.
