How Solar Panels Work: The Basics


What Is the Photovoltaic Effect?

Understanding the science behind solar energy doesn’t require a physics degree. It all starts with the photovoltaic effect — a process where light is converted into electrical energy. When sunlight hits a solar panel, which is made up of many photovoltaic (PV) cells (usually silicon-based), it excites the electrons within those cells. This movement of electrons creates an electrical current — specifically, direct current (DC). However, your home appliances and the UK power grid use alternating current (AC). This is where the inverter comes in. It takes the DC electricity generated by the panels and converts it into AC power, which is then distributed throughout your home to run lighting, heating, appliances, and more.

What Happens to Excess Energy?

In addition to powering your home in real time, solar energy systems can handle excess energy in two ways. First, you can store it using a battery system, allowing you to use that electricity when the sun isn’t shining — such as at night or during power outages. Second, if you generate more electricity than you use, you can feed it back into the grid through the Smart Export Guarantee (SEG), earning credits on your electricity bill.


A Closer Look at Solar Cell Functionality

While that’s the simplified version, the photovoltaic effect itself is fascinating. Silicon, a semiconductor, is key to the process. When light hits a silicon PV cell, it energises the electrons, knocking them loose. These freed electrons are then pushed through an electric field, creating a current. The metal conductors in the solar panel collect this current and send it out to be converted and used. Despite being discovered over a century ago, the PV effect is now more efficient and accessible than ever thanks to advancements in solar technology.

What Warranties and Certifications Should I Check When Buying Solar Panels?

Warranties and Certifications

Investing in solar energy is one of the smartest long-term decisions a homeowner in Dorset can make. Whether you’re focused on cutting electricity costs, reducing your carbon footprint, or increasing the value of your home, solar technology offers substantial benefits.

But one aspect that’s often overlooked is the importance of warranties and certifications. These are more than just fine print — they’re your protection against poor workmanship, faulty equipment, or unexpected breakdowns.

In this guide, we’ll explain exactly what to look for — especially if you’re comparing Growatt battery vs Tesla, considering SunPower Maxeon 7 panels, or looking into systems like Panasonic EverVolt.

panasonic evervolt

Why Warranties Matter

When it comes to solar panels and battery systems, longevity and reliability are crucial. Warranties ensure that the products you’ve invested in continue to perform as promised — and protect you if they don’t.

Without proper warranties, you might find yourself stuck with costly repairs or replacements. These protections also reflect how much confidence a manufacturer or installer has in their own work. A reliable warranty is a sign of quality and accountability.


The Main Types of Warranties to Look For


Product Warranty

This covers defects in materials or workmanship. Top-tier panels like the SunPower Maxeon 7 offer up to 40 years of product coverage, which is far above industry standard.

Batteries such as the Growatt or Panasonic EverVolt typically come with 10-year warranties. Always read the fine print to understand what’s covered and under what conditions.

Performance Guarantee

Over time, all solar panels lose a bit of efficiency. Performance warranties guarantee that your panels will still operate at a high percentage of their original output after 25 years. The SunPower Maxeon 7, for example, has one of the lowest degradation rates in the industry.

Inverter and Battery Warranties

A Tesla Powerwall comes with a 10-year warranty and guarantees around 70% capacity retention by the end of that term. Growatt batteries offer similar warranties, making them a solid alternative.

When comparing a Growatt battery vs Tesla, warranty terms — along with performance and after-sales support — are key considerations.


Certifications: What to Look For in the UK

MCS (Microgeneration Certification Scheme)

If your solar system isn’t MCS-certified, you won’t qualify for incentives like the Smart Export Guarantee. MCS also ensures your products and installers meet rigorous quality standards.

RECC (Renewable Energy Consumer Code)

This consumer protection scheme ensures that installers follow fair trading practices and provide transparent quotes and contracts.

NICEIC

If your installation involves any electrical work — and it will — NICEIC certification ensures the work meets national safety standards.

TrustMark

This is the UK government-endorsed quality standard. It shows your installer has been vetted for technical competence and customer service.

Will a Growatt Battery Work in a Power Cut?

When you invest in solar panels and battery storage, one of the biggest questions on your mind might be: “Will my home still have power if there’s a power cut?”
If you’re considering a Growatt battery system, or already have one installed, you’re not alone in wondering what happens when the grid goes down.

In this article, we’ll explore whether Growatt batteries can keep the lights on during a blackout, how they work alongside your home solar panels, and what you need to know as a South Coast homeowner looking for reliable energy independence.


Why Power Cuts Are a Growing Concern

Power cuts aren’t just a thing of the past. With the UK’s ageing infrastructure, increasing energy demands, and unpredictable weather patterns, outages are still happening — even in well-connected areas like Bournemouth, Poole, Portsmouth, and Southampton.

For homeowners with solar panels, a power cut can feel frustrating. After all, you’re generating electricity — shouldn’t you be able to use it?

That’s where battery storage comes in.

What Is a Growatt Battery?

Growatt is a leading global brand in solar energy storage, known for reliable, efficient and affordable battery solutions. Their home battery systems pair with solar panels to store excess electricity generated during the day, which you can use later — especially during peak pricing times or at night.

But can they help when the grid fails?


Will a Growatt Battery Work in a Power Cut?

The Short Answer:

Yes — but only with the right setup.

By default, Growatt batteries do not automatically provide power during a blackout unless they are installed with Emergency Power Supply (EPS) functionality or connected to a hybrid inverter that supports off-grid operation.


Understanding EPS: The Key to Backup Power

EPS (Emergency Power Supply) is a feature that allows a battery to provide electricity to dedicated circuits in your home when the main grid goes down.

For a Growatt system to function during a power cut:

  • You must have a Growatt hybrid inverter (e.g. MIN or MOD series).
  • EPS functionality must be enabled during installation.
  • Your installer must configure a dedicated backup circuit, usually powering essential items like your fridge, lights, Wi-Fi router, and sockets.

Important: Without EPS, your Growatt battery will shut off during a power cut — even if it’s fully charged. This is a safety feature designed to protect utility workers repairing the grid.


How a Growatt Battery System Works in a Blackout

Here’s what happens when you have EPS configured:

  1. Power Cut Happens
    The grid goes down — your inverter detects the loss of grid power.
  2. EPS Activates Automatically
    Within seconds, your Growatt system switches to backup mode.
  3. Essential Circuits Stay On
    Only the circuits wired into the EPS system will receive power. These are chosen during the installation process.
  4. Battery Powers Your Home
    The battery discharges stored energy to keep your essentials running.
  5. Solar Recharging (Optional)
    If it’s daylight, your solar panels may continue to top up the battery (depending on the system design).

What You Can’t Do During a Blackout

It’s important to manage expectations. Even with EPS:

  • You won’t be able to run high-load appliances like electric ovens or immersion heaters.
  • Your whole house won’t stay powered — just the selected circuits.
  • The backup is not indefinite — it depends on how much energy is stored and how quickly you use it.

That said, for many homeowners, it’s more than enough to stay connected, keep the lights on, and avoid spoiled food or lost internet during an outage.

What Are the Benefits of EPS-Enabled Growatt Batteries?

Energy Security – Stay prepared during storms or infrastructure failures.
Peace of Mind – Know that essentials like lighting, refrigeration, and communication won’t go down.
Smart Solar Use – Even during outages, your battery can power key devices without wasting stored solar energy.
Efficient Load Management – You choose what matters most to stay online when the grid doesn’t.


Do I Need EPS?

If you’re on the South Coast — from Dorset to Hampshire to West Sussex — and want true energy independence, EPS is worth considering. While it’s optional, many homeowners now request it as standard due to its obvious resilience benefits.

Our team at My Home Solar can help you design a system that’s future-proof and ready for anything.

Growatt Battery Cycle Life & Degradation

As solar energy becomes more popular in the UK, homeowners are increasingly turning to battery storage systems to make the most of their renewable energy. Among the leading options in the market is the Growatt GBLI6531 lithium battery, known for its reliability, compact size, and long-lasting performance. But how long can you expect a Growatt battery to last? And what does “cycle life” really mean?

In this blog, we’ll take a friendly and informative dive into the world of battery cycle life and degradation, with a special focus on the Growatt GBLI6531 and other Growatt battery sizes. Whether you’re new to solar or just brushing up on the tech, this guide will help you understand how to get the most from your battery storage investment.

Growatt 6.5k battery

What Is Battery Cycle Life?

Battery cycle life refers to the number of complete charge and discharge cycles a battery can go through before its capacity significantly declines.

A single cycle typically means:

  • The battery is charged to full (e.g. using solar power during the day), and then
  • Discharged completely (e.g. used to power your home in the evening or during outages)

However, partial discharges still count as part of a cycle. For example, two 50% discharges = one full cycle.

Over time, every battery begins to lose capacity with use — this is where battery degradation comes in.

How Long Does the Growatt GBLI6531 Last?

The Growatt GBLI6531 is a 6.5kWh lithium-ion battery designed for home use. It uses LiFePO4 (Lithium Iron Phosphate) technology, which is known for:

  • Long cycle life
  • Strong thermal stability
  • Safe operation

Manufacturer Estimates

According to Growatt’s technical specifications:

  • Growatt Battery Cycle life: >6000 cycles at 90% Depth of Discharge (DoD)
  • Design life: Around 15 years or more (depending on usage and environmental conditions)

To put this in perspective:

  • If you used the battery once a day, every day → that’s over 16 years of reliable use.
  • Even with heavier use (twice a day), you’re still looking at around 8+ years of lifespan.

That’s excellent longevity compared to older technologies like lead-acid, which often manage only 500–1200 cycles.


What Causes Battery Degradation?

Battery degradation is the gradual loss of a battery’s ability to hold and deliver energy. It’s a natural process, but its pace depends on a few key factors:

1. Depth of Discharge (DoD)

The deeper the discharge (i.e., the more of the battery’s stored energy you use), the faster it degrades. LiFePO4 batteries like the Growatt GBLI6531 are well-suited to handle deep discharges (up to 90% or more), but keeping it shallow when possible extends its life.

2. Charge Cycles

More cycles = more wear. But as noted, the Growatt lithium battery is designed for thousands of cycles.

3. Temperature

Batteries prefer stable, moderate temperatures. Excessive heat or freezing cold can speed up degradation. Always ensure your battery is installed in a well-ventilated, weather-protected area.

4. Overcharging/Undercharging

Thanks to integrated Battery Management Systems (BMS), modern batteries like Growatt’s prevent overcharging and over-discharging, protecting the internal cells.


Growatt Battery Sizes and Variants

Growatt offers a range of energy storage options beyond the GBLI6531. Here are some key battery solutions in their lineup:

  • Growatt GBLI6531 – 6.5kWh (the most common for UK home use)
  • Growatt 6.5 battery – often refers to the same GBLI6531, marketed for residential solar systems
  • Growatt NOAH Series – modular systems for flexible capacity (ideal for scaling)
  • Growatt ARK batteries – stackable design; scalable from 2.5kWh to 25kWh
  • Growatt “batterie” / “growatt speicher” – common terms in European markets, especially German-speaking regions (meaning “battery” and “storage” respectively)

These variants allow homeowners and small businesses to match battery size to their energy needs, whether it’s a small flat or a larger detached home with high consumption.


Lithium vs Lead-Acid Batteries: A Quick Comparison

FeatureGrowatt Lithium BatteryLead-Acid Battery

Cost (long-term)More economicalHigher due to frequent replacements

In short, while lead-acid batteries may be cheaper up front, Growatt lithium batteries like the GBLI6531 deliver better long-term value and peace of mind.

Tips to Extend Your Growatt Battery Life

Even though the GBLI6531 is built for endurance, a few good habits will help you maximise its lifespan:

  1. Avoid full discharges when possible
    Partial use is easier on the battery. Don’t always run it to zero.
  2. Keep the battery in a temperate environment
    Indoors or in shaded enclosures work best.
  3. Schedule professional maintenance every 1–2 years
    Just a quick check-up helps spot any potential issues early.
  4. Install with an expert solar technician
    Proper setup ensures safe charging, correct DoD limits, and efficient inverter pairing.
  5. Update firmware
    Ensure your system’s software is up to date to get the best performance and protection.

Storing Sunshine for a Rainy Day

If you’ve taken the leap into solar power or are seriously considering it, you’ve probably come across Growatt batteries. These smart energy storage systems are fast becoming a favourite among UK homeowners—especially in sunny (and sometimes not-so-sunny) Dorset. But while solar panels grab the spotlight, the battery quietly does the heavy lifting behind the scenes. That leads to a vital question: how long will a Growatt battery actually last?

Let’s break it down in plain English—no jargon, just helpful facts, tips, and honest expectations.

Multiple Growatt AXE 5.0L batteries connected in a residential solar setup

What Is a Growatt Battery?

Growatt is a leading brand in renewable energy tech, best known for their inverters and solar batteries. Their ARK series is designed for home use, allowing you to store excess electricity generated during the day and use it in the evening or when the sun isn’t shining.

You’ll typically see model names like:

  • Growatt ARK 2.5 (2.56kWh)
  • Growatt ARK 5.1 (5.12kWh)
  • Growatt ARK 10.2 (10.24kWh)

These modular systems can scale up based on how much energy storage you need, making them perfect whether you’ve got a modest solar setup or a full-blown eco-friendly home.


So, How Long Do Growatt Batteries Last?

The simple answer? 10 to 15 years on average—but let’s get more specific.

Growatt batteries, like most lithium iron phosphate (LiFePO₄) batteries, are built to last thousands of cycles. A cycle means one full charge and discharge.

Lifespan by the Numbers:

  • Cycle life: ~6,000+ cycles (for most ARK models)
  • Daily use estimate: 1 cycle per day
  • Expected lifespan: 10–16 years under normal use

So, if you use your battery daily to store and discharge solar power, you’re likely to get at least a decade of reliable performance before its capacity starts to noticeably decline.


What Affects a Growatt Battery’s Lifespan?

Even the best battery won’t last forever—but the way you use it has a big impact. Here’s what can speed up or slow down battery ageing:

1. Charging Cycles

The more often a battery is fully charged and discharged, the quicker it wears down. However, Growatt batteries are smart—they manage charging efficiently to reduce unnecessary stress.

2. Depth of Discharge (DoD)

This is how much of the battery’s energy is used before recharging. Shallower discharges (like using only 50% of the capacity) can lead to longer lifespan compared to draining it down to zero every day.

3. Ambient Temperature

Batteries love a stable climate. Extreme cold or heat can stress the battery’s internal chemistry. In the UK (especially coastal areas like Dorset), milder temperatures generally work in your favour—but it’s still smart to install batteries in sheltered locations.

4. Installation Quality

If your system isn’t set up properly—poor ventilation, dodgy wiring, or cheap components—it’ll wear out faster. Make sure your installer is MCS-certified and knows how to handle battery systems.

5. Software & Firmware Updates

Growatt batteries come with advanced battery management systems (BMS). These keep everything running smoothly—but only if you keep them updated.


Comparing Growatt Battery Models (ARK Series)

Let’s take a quick look at the differences that might influence longevity or performance:

ModelCapacityTypical UseEstimated Lifespan (cycles)
ARK 2.52.56 kWhSmall homes / starter systems6,000+
ARK 5.15.12 kWhMedium usage / daily cycling6,000+
ARK 10.210.24 kWhHigh-demand homes / larger arrays6,000+

All these models use LiFePO₄ technology, which is widely considered the safest and most durable lithium battery chemistry on the market.


Tips to Maximise Your Growatt Battery Lifespan
