☀️🚗 Have solar panels and an electric car? Charging it during the day might seem like the obvious choice, but it isn’t always the cheapest one.

If your charger can follow the surplus electricity from your solar panels, it can send energy that would otherwise be exported straight into your car. This can help you use more of the electricity you generate at home.

But your electricity tariff matters too.

Some EV tariffs offer cheaper electricity for a few hours overnight. Depending on your import and export rates, you could actually be better off exporting your solar electricity during the day and charging your car from the grid overnight.

For example, if you’re paid more for exporting a unit of solar electricity than it costs to import a unit overnight, using the cheaper EV rate may make more financial sense.

There isn’t one charging routine that works for everyone. It depends on:

🔌 Your daytime solar generation
🔌 Your export rate
🔌 Your overnight EV rate
🔌 When your car is at home
🔌 How many miles you need to add
🔌 Whether you also have a home battery

The best setup doesn’t just generate electricity, it decides when that electricity is most valuable to your household.

Before setting your charging schedule, compare your EV tariff and export tariff rather than automatically assuming daytime charging will always save you the most. ☀️🔋🚗

☀️🚗 Oes gennych chi solar panels a char trydan? Mae gwefru’r car yn ystod y dydd yn swnio fel y dewis amlwg, ond dydy o ddim wastad yr opsiwn rhataf.

Os ydy’ch charger yn gallu defnyddio’r trydan sbâr o’ch solar panels, mae’n gallu anfon y trydan fyddai fel arall yn mynd yn ôl i’r grid yn syth i mewn i’r car. Mae hyn yn eich helpu chi i ddefnyddio mwy o’r trydan rydych chi’n ei gynhyrchu adra.

Ond mae’ch tariff trydan chi’n bwysig hefyd.

Mae rhai EV tariffs yn cynnig trydan rhatach am ychydig o oriau dros nos. Felly, yn dibynnu ar eich pris import ac export, efallai byddai’n well i chi anfon eich trydan solar yn ôl i’r grid yn ystod y dydd a gwefru’r car yn rhatach dros nos.

🔥“£9,000 towards a heat pump sounds great…but what’s the catch?”🔥
🔥“Mae £9,000 tuag at bwmp gwres yn swnio’n grêt… ond beth yw’r dal?”🔥

Will it actually keep my house warm?
Will I still have thousands left to pay?
Do I need to be on benefits?
Is my home even suitable?
Will the installation turn the house upside down?
And am I going to be left filling in endless forms?

If those are the thoughts running through your head, you’re definitely not the only one.

The £9,000 Boiler Upgrade Scheme grant is available to eligible homeowners replacing an oil or LPG heating system, and it isn’t means-tested. We’ll assess your home properly, explain what system it needs and give you a clear quotation showing what you would pay after the grant.

If you decide to go ahead, we’ll also handle the grant application and paperwork for you. No guessing, no confusing forms and no being passed from one person to another.

This customer had exactly the kind of experience you’d hope for: their old oil boiler was replaced, the process was smooth, the house was left clean each day and the £9,000 grant paperwork was all taken care of.

Still thinking, “It sounds good, but would it work for my house?”

Let’s find out. Call our team on 01248 421044 or send us a message for a friendly, no-pressure chat.

“Mae £9,000 tuag at bwmp gwres yn swnio’n grêt… ond beth yw’r dal?”

Fydd o wir yn cadw fy nhŷ yn gynnes?
Fydd gen i filoedd o bunnoedd ar ôl i’w talu?
Oes rhaid i mi fod ar fudd-daliadau?
Ydi fy nhŷ i’n addas?
Fydd y gwaith gosod yn gwneud llanast o’r tŷ?
A fydd rhaid i mi lenwi llwyth o ffurflenni?

Os mai dyma’r cwestiynau sy’n mynd drwy eich meddwl, dydych chi ddim ar eich pen eich hun.

Mae grant £9,000 y Boiler Upgrade Scheme ar gael i berchnogion tai cymwys sy’n newid system wresogi olew neu LPG. Dydi’r grant ddim yn dibynnu ar eich incwm.

👀 When did you last have your heat pump serviced?

Here’s something that’s easy to forget: regular servicing may be a requirement of your manufacturer’s warranty.

So, even if your heat pump seems to be working perfectly, missing a required service could affect your warranty cover later on.

A regular service helps keep everything running efficiently, catches potential problems early and gives you the service record you may need if you ever make a warranty claim. 🔧

Not sure when yours was last serviced? Give the Menai team a call on 01248 421044 and we’ll help you check. 🏠

👀 Pryd gafodd eich pwmp gwres chi service ddiwethaf?

Dyma rywbeth sy’n hawdd anghofio amdano: efallai bod service rheolaidd yn un o amodau warranty y manufacturer.

Felly, hyd yn oed os ydy’r pwmp gwres yn gweithio’n iawn, gall methu service effeithio ar y warranty os bydd rhywbeth yn mynd o’i le wedyn.

Mae service rheolaidd yn helpu’r system i redeg yn effeithlon, yn gallu dod o hyd i broblemau’n gynnar ac yn rhoi’r cofnodion service y gallai fod eu hangen os bydd rhaid gwneud claim ar y warranty. 🔧

Ddim yn siŵr pryd gafodd eich un chi service ddiwethaf? Ffoniwch dîm Menai ar 01248 421044 ac mi wnawn ni helpu. 🏠

🔋 Already have solar panels and wondering if you can just add a battery?

If your system already has a compatible hybrid inverter, the answer is usually yes, the battery can be added to work alongside it.

If you have a standard string inverter, it’s not always quite as simple. The inverter may need to be changed to a compatible hybrid model before the battery can be connected.

We’d also check the age of your existing equipment, the battery compatibility and how much electricity your home actually uses before recommending anything.

After all, there’s no point fitting a huge battery if your solar system won’t regularly fill it or if you’re unlikely to use all the energy stored inside it.

Already have solar and not sure which inverter you’ve got? Send us a photograph of it or call the Menai team on 01248 421044, and we can point you in the right direction. ☀️

🔋 Wedi cael solar panels yn barod ac yn meddwl os fedrwch chi ychwanegu battery?

Os oes gan eich system hybrid inverter sy’n compatible yn barod, yr ateb fel arfer ydy oes, mae’n bosib ychwanegu battery i weithio efo fo.

Os oes gennych chi string inverter arferol, dydy hi ddim wastad mor syml â hynny. Efallai bydd angen newid yr inverter am hybrid inverter compatible cyn cysylltu’r battery.

Mi fyddwn ni hefyd yn edrych ar oed a chyflwr eich offer presennol, pa battery sy’n compatible a faint o drydan mae’ch cartref chi’n ei ddefnyddio cyn awgrymu unrhyw beth.

Wedi’r cyfan, does dim pwynt gosod battery mawr os na fydd eich system solar yn ei lenwi’n rheolaidd, neu os na fyddwch chi’n defnyddio’r holl ynni sydd wedi’i storio ynddo.

Wedi cael solar yn barod ond ddim yn siŵr pa fath o inverter sydd gennych chi? Anfonwch lun ohono atom ni, neu ffoniwch dîm Menai ar 01248 421044, ac mi wnawn ni eich rhoi chi ar y trywydd iawn. ☀️

☀️ Two solar quotes both include 10 panels, so why might they be completely different?

Because the number of panels only tells you one small part of the story.

One panel may produce more electricity than another, but the design also needs to consider the inverter type and size, the direction of your roof, shading and how the panels will be positioned.

Then there’s the expected annual generation, any export limitations from the DNO, system monitoring, equipment warranties and the installation itself—including how the panels will be fitted to your roof, whether scaffolding is included and what aftercare you’ll receive.

A cheaper quote with the same number of panels doesn’t necessarily offer the same system, performance or level of installation.

When comparing solar quotes, don’t just ask, “How many panels am I getting?”

Ask, “How has this system been designed for my home?” 🏠☀️

☀️ Mae dau quote solar yn cynnwys 10 panel, felly pam eu bod nhw’n gallu bod mor wahanol?

Achos dim ond un rhan fach o’r system ydy nifer y panels.

Gall un panel gynhyrchu mwy o drydan nag un arall, ond mae angen meddwl hefyd am fath a maint yr inverter, cyfeiriad y to, unrhyw gysgod a lle bydd y panels yn cael eu gosod.

Yna mae faint o drydan mae’r system yn debygol o’i gynhyrchu bob blwyddyn, unrhyw gyfyngiadau gan y DNO, sut fedrwch chi fonitro’r system, y warranties a’r gwaith gosod ei hun. Mae hyn yn cynnwys sut bydd y panels yn cael eu gosod ar eich to, os ydy sgaffald wedi’i gynnwys a pha help fydd ar gael ar ôl y gwaith.

Dydy quote rhatach gyda’r un nifer o panels ddim wastad yn golygu’r un system, yr un perfformiad na’r un safon o waith.

Wrth gymharu quotes solar, peidiwch â gofyn dim ond:

“Faint o panels ydw i’n eu cael?”

Gofynnwch:

“Sut mae’r system yma wedi cael ei dylunio ar gyfer fy nghartref i?” 🏠☀️

Happy Bank Holiday Monday! ☀️

Here’s a little battery fact for your day off…

Have you ever looked at your monitoring app and wondered why your battery has stopped discharging even though it still shows some charge remaining?

It doesn’t necessarily mean there’s a fault.

Battery systems normally have a minimum charge level set, sometimes called a reserve or minimum state of charge. This prevents the battery from being completely drained and helps protect it.

Depending on your system and its settings, some stored energy may also be reserved for backup power if EPS has been installed.

So, if your battery reaches its minimum level and starts using electricity from the grid, it may simply be following its settings rather than failing to work.

The exact reserve level varies between systems, so speak to your installer before changing anything in the app. 🔋⚡

Enjoy the Bank Holiday from everyone at Menai.

Dydd Llun Gŵyl y Banc Hapus! ☀️

Dyma ffaith fach am fatris i chi ar eich diwrnod i ffwrdd…

Dach chi erioed wedi edrych ar eich ap monitro a meddwl pam mae’ch batri wedi stopio rhoi trydan allan, er bod rhywfaint o wefr dal ar ôl ynddo?

Dydy hyn ddim o reidrwydd yn golygu bod rhywbeth o’i le.

Fel arfer, mae gan system fatri lefel gwefr isaf wedi’i gosod. Mae hyn weithiau’n cael ei alw’n lefel wrth gefn. Mae’n atal y batri rhag cael ei wagio’n llwyr ac yn helpu i’w ddiogelu.

Yn dibynnu ar eich system a’i gosodiadau, efallai bydd rhywfaint o’r trydan hefyd yn cael ei gadw ar gyfer pŵer wrth gefn os oes EPS wedi’i osod.

Felly, os ydy’ch batri’n cyrraedd ei lefel isaf a’ch cartref yn dechrau defnyddio trydan o’r grid, efallai ei fod o’n dilyn ei osodiadau—dydy o ddim o reidrwydd wedi stopio gweithio.

Mae’r lefel wrth gefn yn wahanol ar bob system, felly siaradwch â’ch gosodwr cyn newid unrhyw beth ar yr ap. 🔋⚡

Mwynhewch Ŵyl y Banc gan bawb yma ym Menai.

🌡️ Heat pump fun fact!

A heat pump often works best when you stop treating it like a boiler.

Many of us are used to switching a boiler on, blasting very hot water through the radiators and then turning it off again once the house feels warm.

A heat pump is different. It normally works more efficiently by running at a lower temperature for longer, gently replacing the heat your home loses throughout the day.

Think of it like driving at a steady speed instead of repeatedly accelerating and braking. 🚗

This doesn’t mean your home should feel colder. When the system has been properly designed, the aim is to maintain a comfortable, consistent temperature without those big swings between feeling too hot and too cold.

So, one of the biggest adjustments isn’t necessarily the technology, it’s changing how we think our heating should work.

Would you prefer steady comfort throughout the day or short blasts of heat?

🌡️ Ffaith ddifyr am bympiau gwres!

Mae pwmp gwres yn aml yn gweithio orau pan dach chi’n stopio ei drin fel boeler.

Mae lot ohonon ni wedi arfer troi’r boeler ymlaen, anfon dŵr poeth iawn drwy’r rheiddiaduron, ac yna ei ddiffodd unwaith mae’r tŷ wedi cynhesu.

Mae pwmp gwres yn gweithio’n wahanol. Fel arfer, mae’n gweithio’n fwy effeithlon ar dymheredd is am gyfnod hirach, gan gadw’ch cartref yn gynnes ac yn gyfforddus drwy’r dydd.

Meddyliwch amdano fel gyrru ar gyflymder cyson, yn lle cyflymu a brecio drwy’r amser. 🚗

Dydy hyn ddim yn golygu y dylai’ch cartref deimlo’n oerach. Pan mae’r system wedi cael ei dylunio’n iawn, y nod ydy cadw’r tymheredd yn gyfforddus ac yn gyson, heb fynd o deimlo’n rhy boeth i deimlo’n rhy oer.

Felly, un o’r newidiadau mwyaf ydy nid y dechnoleg ei hun, ond newid y ffordd rydan ni’n meddwl am sut dylai’n gwresogi weithio.

Fyddai’n well gynnoch chi gael gwres cyson drwy’r dydd, neu gyfnodau byr o wres uchel?

⚡ Would your battery keep working during a power cut?

Not automaticallyand this is something worth thinking about before your solar and battery system is installed.

For safety reasons, a standard solar and battery system will normally switch off during a power cut. However, an Emergency Power Supply, commonly known as EPS, can be added to use the energy stored in your battery to keep selected essential circuits running.

Depending on how your system is designed, this could include:

💡 Essential lighting
🧊 Your fridge or freezer
📶 Broadband
🌡️ Heating controls

EPS is an optional add-on and doesn’t necessarily provide backup power to your entire home. How long it can keep your selected essentials running will also depend on your battery’s capacity, how much charge it has and how much electricity you’re using.

Because EPS requires additional equipment and electrical work, it’s best to consider whether backup power is important to you before your installation is designed.

You can select EPS as an option when creating your free online quote using Simplify, helping us understand exactly what you would like from your system. 🔋

⚡ Fyddai’ch batri’n dal i weithio yn ystod toriad pŵer?

Ddim yn awtomatig – ac mae hyn yn rhywbeth sy’n werth meddwl amdano cyn i’ch system solar a batri gael ei gosod.

Am resymau diogelwch, bydd system solar a batri arferol yn diffodd yn ystod toriad pŵer. Ond mae modd ychwanegu Cyflenwad Pŵer Brys, neu EPS, sy’n defnyddio’r ynni sydd wedi’i storio yn eich batri i gadw rhai pethau hanfodol i fynd.

Yn dibynnu ar sut mae’ch system wedi cael ei dylunio, gallai hyn gynnwys:
