πŸš— Darker evenings, more time at home…

For many EV owners, autumn can mean different charging routines as daily habits change.

A dedicated home EV charger can provide a convenient way to charge an electric vehicle at home, subject to the appropriate installation and electrical requirements.

If you are considering one, we can talk you through the options.

🏑 Is your home ready for winter?

October is a good month for a little energy check.

βœ”οΈ Check your heating controls
βœ”οΈ Look for obvious draughts
βœ”οΈ Review your lighting
βœ”οΈ Check appliances and standby use
βœ”οΈ Think about how and when you use electricity

And if you are considering a bigger change, such as solar PV, battery storage or low-carbon heating, start researching your options now.

πŸ’‘ Your energy habits change with the seasons

In summer, you might spend more time outdoors and rely less on lighting.

By October, the lights are on earlier, evenings are longer, and heating may be back in regular use.

That is one reason it is useful to understand when and how your household uses energy when considering renewable energy and battery storage.

🌳 Autumn leaves + solar panels

Beautiful to look at. Not always helpful if they are covering your panels.

Leaves and other debris can cause shading or obstruction, so it is worth keeping an eye on your system during autumn.

But please DO NOT climb onto your roof to clean them yourself.

If you have concerns about your installation, contact a suitably qualified professional.

πŸ”‹ Battery storage isn’t just about having solar

Battery storage can be installed as part of a solar PV system, but batteries can also be considered alongside other electricity arrangements depending on the property and system design.

Their role is to store electricity for potential use at another time.

Whether battery storage is appropriate depends on your circumstances, energy usage and the proposed system.

πŸŒ₯️ Can solar panels work on an overcast day?

Yes, solar PV systems can generate electricity from daylight even when the sky is cloudy.

However, the amount generated varies according to factors including available daylight, weather conditions, shading and system design.

So while October may look very different from June, your solar system does not simply switch off when the clouds arrive.

Today we attended the 'What Next' 2026 Careers Fair at Ysgol Y Gogarth, alongside around 200–250 learners from 11 ALN educational settings across the whole of North Wales ❀️

The day gave ALN learners the opportunity to explore different industries, meet employers and discover the pathways that could be available to them after leaving school. The learners took a liking to our solar powered toys and we had a lot of interest in Construction/Renewable Energy roles - bringing up important conversations about the future of our world and how we can all make a difference.

But today wasn’t only about asking young people β€œWhat Next?” β€” it was also about asking ourselves, as employers and organisations, β€œWhat can we do next?”

These events open up valuable conversations between the organisations in the room. They give us the chance to make important new connections, share ideas and speak honestly about what may still be missing. By understanding what other organisations are already doing β€” and where the gaps remain β€” we can discover new ways to work together, strengthen the support available and create even more meaningful opportunities for young people and our wider communitiesπŸ‘·β€β™€οΈ

No single business or organisation can do everything alone. But when we come together, share our knowledge and connect with the right people, we can achieve so much more!

A brilliant and genuinely worthwhile day. Thank you to
Careers Wales, Ysgol Y Gogarth and everyone who helped bring it together.

πŸ‚ October has arrived

The evenings are getting darker, temperatures are dropping and we are heading into a very different energy-use season.

If renewable energy is something you have been considering, autumn is a good time to understand your options and start planning ahead.

From solar PV and battery storage to EV charging and low-carbon heating, we can help you explore what may be suitable for your property.

πŸ”‹ Battery storage: daytime vs evening

One reason battery storage interests homeowners is the ability to store electricity for later use.

For example, electricity generated during daylight hours may be stored and subsequently used later, depending on the system and how it is configured.

The right setup depends on your individual circumstances. To learn more get in touch today!

πŸ‘· What makes a good installation?

It is not simply about putting panels on a roof.

Good planning considers the property, system design, electrical requirements, installation conditions and how the system is intended to operate.

Getting the details right matters.
