Microgeneration Certification Scheme (MCS)

Ever heard of Microgeneration Certification Scheme (MCS)?

If not, let me enlighten you, my friend.

The MCS is a big shot – a globally acknowledged mark of quality, acting as a catalyst in endorsing renewable energy sources (talk about being eco-friendly!).

Now, the spotlight's on the smaller players - low-carbon technologies that focus on heat and electricity generation.

Believe it or not, we Brits are pretty ahead of the curve. According to Department for Business, Energy & Industrial Strategy, as of 2021, over 6% of UK households were equipped with low-carbon heating technologies. Cool, eh?!

The MCS has been smashing it in 2023, notching up more than 1,700 new recruits earning their certifications within a span of 11 months, would you believe it? That's a stonking 70% increase in the roster since the close of last year. And you know what else? The number who've signed up for MCS in this year alone outnumbers the intake for the last six years combined.

Definition and Purpose of the MCS

The Microgeneration Certification Scheme (MCS) sets a high bar for installation companies and products involved in microgeneration, encompassing the whole wide world of renewable energy technologies - solar panels, wind turbines, heat pumps, you name it. Reassuring, isn't it?

It’s like a quality stamp that ensures that your instals meet the stiffest standards of the industry. In 2023 so far, the MCS issued a whopping 143,562 certificates for installations in the UK (source: MCS Dashboard). 

So, if you're mulling over, unsure about whether to take the plunge into renewable energy, an MCS certification provides that boost of confidence that your chosen system won't let you down.

International Quality Assurance Scheme

Think of the Microgeneration Certification Scheme (MCS) as your trusty, reliable friend in the world of microgeneration technologies— providing that much-needed seal of approval.

Picture it, if you're a business or individual keen to grab hold of those tempting financial incentives, it's MCS that gives you the green light.

Plus, for consumers, having that MCS stamp means you can sleep easy, knowing professionals carrying out installations aren't just winging it with knock-off equipment. 

Instead, they're completely clued up and using solar panel kit that's got the thumbs up. Isn't that reassuring?

MCS Certification for Solar Panel Installations

Solar panel installations have gained immense popularity in recent years as a renewable energy solution. Not only do they help reduce carbon emissions and combat climate change, but they also offer significant financial benefits to homeowners.

What is MCS certification?

If you were to ask me, "Why the blazes should I choose an installer who's MCS-certified?" I'd tell you exactly why. It's dead simple really. Opting for an MCS-accredited chap (or chapette) offers not just a semblance, but actual heaping buckets of peace of mind. And here's why: 

First off, they ensure your shiny new solar panel installation sticks to all the required regulations and safety jazz, so no unwanted surprises for you.

Moreover, the gear they use is top-notch. And when I say top-notch, I'm talking about stuff that meets the highest performance standards. No cheap knock-offs here, mate.

And of course, these installers aren't just any ol' Tom, Dick or Harry. These folks have been through the mill - fully trained and skilled to perfection for the job at hand.

Quality Through MCS Standards and Compliance

Ever been tricked by inferior quality?

We've all been there. Here's the thing: solar panel installations are no different. The quality of the solar panels—from the supply chain to the final product—directly hits their performance. 

The risks?

Inefficiency, safety hazards, and a system driven down by Father Time—all quicker than you can say 'solar.' 

So, trust me when I tell you, you want your installations to be MCS-approved, from start to finish.

Leave the risks for the horror flicks and say 'Hello' to MCS-approved products and services!

Design and Installation Process by MCS-Accredited Professionals

When it comes to the design and installation process executed by our trusted MCS-accredited pros, rest assured, they stick to a hefty bunch of industry rules to guarantee top-notch results. Let's take a whistle-stop tour of the critical stages in this process, shall we?

1. Initial Assessment

Now, here comes the fun part: MCS-accredited experts roll up their sleeves, take a good look around your property, and work their magic to come up with the best solar panel system design just for you!

What's in their secret recipe, you're wondering?

Well, it's all about judging the lay of the land (or in this case, the tilt of your roof), figuring out your home's orientation, and checking how much room they've got to work with.

2. System Design

The qualified installers formulate a custom-made system design. This design not only syphons energy like there's no tomorrow, but it also tip-toes around the intimidating building regulations and sticks to the guidelines of our friend, the MCS.

3. Component Selection

Picking the right parts is a bit of a big deal, wouldn’t you say?

Well, those MCS-accredited installers feel just the same, hence their knack for selecting top-notch solar panels, inverters, and mounting systems among others, all to guarantee a reliable and efficient system.

A touch of quality control that your energy setup will thank you for.

4. Installation
  • During the nitty-gritty phase of installation, precision becomes our middle name. There's a hefty amount of focus on how the panels are clamped down, the wiring bit (don't want any of those rogue sparks now, do we?), and a good ol' test run to ensure everything's tickety-boo and primed for some serious sun catching!

MCS Battery Installation Standard

The good folks at MCS (Microgeneration Certification Scheme) have made a bit of history themselves. They've brought our industry its first-ever framework dedicated to battery storage system installations. Come on, give them a round of applause, won't you? 

Now, this brand new Battery Installation Standard, or MIS 3012, lays down the law for MCS accredited installers. Everything from supply, design, and installation of battery systems to Electrical Energy Storage Systems (EESS) from classes 1 through 4. 'Hang on, classes 1 through 4?' you ask. Well, brace yourself because we're headed to 'Technical Standards 101' here — and it covers systems up to a kaboom-worthy 50kW. 

2020 was the year MCS thought they'd trial this scheme — with the help of a bunch of willing volunteer installers. They've paved the way for certification bodies to finally start accepting applications for certification. Let's toast to them, shall we? 

MCS has cleverly categorised them into four classes, for this standard [1]

  • Class 1 – all the components in the same enclosure, or multiple enclosures from the same manufacturer but with no visible direct current (DC) cable.
  • Class 2 – battery modules and inverter in separate enclosures linked by a DC cable but both components from the same manufacturer.
  • Class 3 – as class 2 but where the battery modules and inverter are from different manufacturers, requiring the installer to determine compatibility.
  • Class 4 – all components, including battery modules, safety devices and inverters, could all be from different manufacturers but are selected and assembled by the installer to be compatible with each other.

MCS developed MIS 3012 with input from industry-leading bodies, including Tesla, Sonnen, Moixa, Powervault, AceOn Group, Solar Energy UK, and REA.
