What is EPS for Solar & how does it work?

We all love the idea of harnessing the sun’s power to light up our homes, but what happens when the grid decides to take an unexpected nap?

That’s where EPS comes in, our trusty backup plan. Today, we’re delving into an increasingly important aspect of solar energy systems: Emergency Power Supply (EPS).

Imagine EPS as that reliable friend who’s always there when you need them, ensuring that even during the darkest times (quite literally), you’re not left stumbling for candles. It’s all about keeping your home powered and your life running smoothly, regardless of what’s happening outside.

The importance of EPS extends beyond mere convenience. It embodies the strides towards energy independence, allowing solar system owners to maintain power autonomously. Additionally, by relying on EPS, we contribute to a greener planet, reducing our reliance on fossil-fueled power sources and decreasing our carbon footprint.

So, whether you’re a solar power newbie or you’ve been riding the solar renewable wave for years, understanding EPS is vital. Our aim is to equip you with the knowledge to enhance your solar investment, ensuring that your energy supply is as reliable as the sunrise yet unfazed by grid disruptions.

what is eps for solar?

EPS, or Emergency Power Supply, refers to the system that provides power backup when the main grid power is unavailable.

Unlike the continuous power flow from traditional grid or solar sources, EPS activates only during power interruptions, ensuring that essential functions can continue without disruption. It’s a safety net that enables solar-powered premises to maintain electricity during unforeseen grid failures.

A solar power system with EPS operates by detecting grid outages almost instantaneously. Upon detection, it isolates the solar system from the grid to prevent back-feeding (which could be dangerous to utility workers). It switches to backup mode to supply power directly from the solar panels and/or storage batteries. This seamless transition ensures that critical appliances and lights remain operational, even during extended power outages.

when does an eps system work?

Activation of the EPS is automatic upon grid failure, with no manual intervention required.

The system instantly isolates from the grid, ensuring safety and compliance with regulatory standards. Power is then rerouted from the batteries (and solar panels, if conditions permit) to the critical load panel, supplying electricity to designated essential appliances and fixtures.

It is a common myth that solar panels and solar battery storage will automatically provide backup storage in the case of a power cut. However, by law, a standard home solar panel system is required to be disconnected from the grid in the event of power failure for the safety of the grid workers. Only certain types of EPS systems and inverters can get around this.

components of an eps system

An efficient EPS system comprises several key components, each playing a crucial role in delivering backup power:

solar inverter with eps functionality

Many modern solar inverters come equipped with EPS capabilities, allowing them to switch between grid and backup power modes. These inverters manage the distribution of solar power, prioritising battery charging and supplying power to critical loads during outages.

battery storage

Batteries are central to an EPS system, storing excess solar energy generated during the day for use when the grid goes down. The capacity and type of battery (e.g., lithium-ion, lead-acid) determine the duration and amount of power available during an outage.

control system

This component oversees the entire EPS system, monitoring grid status, managing power flow, and ensuring efficient operation of the backup system. It decides when to charge or discharge the batteries and when to switch to EPS mode.

critical load panel

A critical load panel is often installed to separate essential circuits that will be powered by EPS from non-essential ones that will not. This ensures that power is prioritised for crucial needs, such as lighting, refrigeration, and medical equipment.

levels of eps

automatic sockets

Your solar battery system can include a dual 13A socket wired as an EPS outlet, offering a cost-effective enhancement to any solar PV setup. This outlet allows the inverter to swiftly disconnect from the grid and redirect power to the socket during an outage, taking mere seconds. It’s particularly handy for running smaller appliances, such as charging a mobile phone or powering a lamp, drawing energy at rates of either 3kW or 5kW, depending on the specifications of your battery and inverter.

automatic circuits

Integrating an additional consumer unit and some wiring allows the battery inverter to control one or more electrical circuits directly, typically those for lighting and possibly the refrigerator. In the event of a power outage, these circuits will, after a brief pause, automatically receive power from the battery. This method is constrained by the EPS output’s power limits, making it unsuitable for supplying electricity to an entire house.

manual whole house backup

During a power outage, the homeowner has the option to manually switch off all high-consuming devices and activate a switch to supply the entire house from the battery. This manual changeover involves rerouting both the incoming grid connection and the main consumer unit through the battery system. This setup requires manual intervention but promotes energy conservation by encouraging the homeowner to deactivate high-energy appliances, preserving battery life for essential needs.

automatic whole house backup

For those aiming to power their whole home continuously, with or without grid access, an off-grid energy inverter presents an optimal solution. These solar PV systems can handle significant loads, automatically switching to battery power during outages. While seamless, this option requires a sizable battery to meet household demands, which can be expensive.

automatic whole house backup (with off-grid capabilities)

In designs where the battery inverter powers the solar inverter, the system can maintain home power independently of the grid connection. This setup ensures that, provided there’s sunlight, the system can power your home continuously, offering complete off-grid functionality. Systems exemplify such configurations, overcoming the limitations of battery capacity and storage at the moment of grid failure by relying on continuous solar power.

choosing the right eps for your needs

Choosing the appropriate level of EPS depends on several factors, including your energy needs, budget constraints, and the frequency and duration of local power outages.

First and foremost, evaluate your energy consumption patterns and identify which appliances and systems are crucial during a power outage. Considerations include not just the essentials like lighting and refrigeration but also any medical equipment, heating or cooling needs, and connectivity devices. Understanding your priority needs will guide you in selecting the EPS level that aligns with your lifestyle or business operations.

While it’s important to meet your energy needs, it’s equally vital to consider your budget. Basic EPS setups are more affordable but offer limited coverage, whereas advanced systems provide extensive backup at a higher cost. Balance your need for backup power with what you are willing to invest.

Armed with a clear understanding of your needs and the options available, consult with solar energy professionals to discuss your situation. They can provide insights into the most cost-effective and efficient systems for your specific requirements. Also, consider the longevity and warranty of the equipment, as these factors will impact the system’s value over its lifetime.

Do Solar Panels work in the Winter or on Cloudy days?

Have you ever wondered whether solar panels lose their effectiveness when the winter chill sets in or on cloudy, overcast days? What happens on the winter days when there is only sunlight for (on average) 7 hours and 49 minutes in the UK? (Source, 2024)

In the UK, cloudy days are a regular occurrence, so it is only understandable why people ask the question,“Do solar panels work on cloudy days and in the winter?”. Many people believe that solar panels thrive only under the brilliant sun of summer days.

However, this is where we come in to debunk some common myths. Rest assured that this is merely a widespread myth that solar panels are less effective during the winter and on cloudy days. Solar energy is still a dependable and resilient source of renewable energy. They can benefit from the sun’s natural energy in every month of the year – even on cloudy and short winter days.

We aim to shed light on how solar panels continue to perform, not just when bathed in sunlight, but also during the colder, cloudier days of the year. We’ll explore the intriguing ways in which solar panels harness light to generate energy, regardless of the season. Additionally, we’ll delve into the pivotal role of solar battery storage in ensuring a steady supply of energy, whatever the weather may bring.

How do solar panels work?

Firstly, we need to understand how solar panels operate and what makes them produce energy.

At first glance, solar panels might seem like sheets of dark glass sitting atop roofs, quietly basking in the sunlight. But at the heart of every solar panel are photovoltaic (PV) cells, which essentially generate power from daylight, not sunlight or heat.

PV cells are made using semi-conducting substances, often silicon. When the light shines on the silicone, the cells get excited. This excitement isn’t just for show; it’s the silicon electrons getting all hyped up and moving around, which creates an electrical current. It’s this current that is harnessed and converted into the electricity that powers everything from your kettle to your TV.

How do solar panels work on cloudy days and in the winter?

Solar panels don’t need the sun to be shining brightly to work their magic. They need light.

Yes, even on those grey, overcast days, there is still enough light filtering through the clouds to get those silicon electrons grooving.

And in the chill of winter?

The cold can actually make solar panels work more efficiently. Think of it like this: on a crisp, cold day, you might perform better on your morning run compared to a sweltering hot day. Similarly, the cooler temperatures can help improve the performance of the solar panels, making them more efficient at converting sunlight into electricity.

So, while solar panels love basking in direct sunlight, they’re not sunbathers at heart. They’re hard at work, come rain or shine, converting whatever light they can get into clean, green energy. It’s a reminder that even on the days when the sun seems to be playing hide and seek, your solar panels are still on the job, doing their bit for your home and the planet.

Of course, winter brings its own set of challenges, like the occasional blanket of snow covering the panels. But, just as you might sweep your walkway, a quick brush-off of the panels can get them back to their energy-producing glory. And let’s not forget the angle of installation; many solar systems are set up with winter in mind, tilted to catch the sun’s lower trajectory across the sky.

The myths of inactivity: The Cloud Edge Effect

Solar panels can work with diffused light. Although the amount of sunlight is reduced, it doesn’t disappear completely on cloudy days.

The light that filters through is still captured by solar panels, which continue to generate electricity.

Solar panels are more like tortoises than hares on cloudy days. The energy production won’t break any records, but it’s steady, proving the point that every little helps. In fact, some types of solar panels, particularly those designed to capture a broader spectrum of light, can be adept at working in lower light conditions, making them effective even when the sun has taken a day off.

There is also the phenomenon known as the cloud edge effect.

This occurs when solar irradiance is actually higher right as a cloud passes over a solar array. In other words, this happens when the sun peeks around the edges of clouds, leading to a temporary boost in light intensity. Solar panels love this and can produce even more power than on a cloudless day, although briefly. The sunlight is magnified, resulting in a significantly higher electrical output which, just like humans when they’re running and suddenly get a burst of energy, the cloud edge effect can give solar cells that little extra boost.

So, regardless of whether it is winter, cloudy, or a rainy day, solar panels are up there, quietly and efficiently converting whatever light they can get into energy. It’s a reminder that, in the world of solar energy, every day is a good day; some are just a bit more productive than others.

Maximising solar panel winter performance

You might be wondering, “How can I ensure my solar setup is putting its best foot forward during the winter months?”.

Fear not, for we have a few tricks up our sleeve to keep your panels performing at their peak, even when the weather outside is more suited for a cup of hot cocoa by the fire.

Let there be light (on your panels)

First things first, let’s talk about keeping those panels clear. Snow might look pretty, but it’s not exactly a friend to solar production. A simple sweep with a soft brush or a solar panel snow rake can work wonders. Remember, even a thin layer of snow can significantly reduce your panels’ effectiveness, so keep them as clear as you can.

Angle for Success

As the sun decides to take a lower arc across the sky in winter, the angle of your solar panels becomes even more crucial. If adjustable, tilting your panels to capture more of that precious winter sunlight can make a noticeable difference. The ideal angle varies depending on your location, but aiming for a steeper tilt helps catch the sun’s lower trajectory.

Embrace regular check-ups

Winter is a great time to give your solar system a health check. Ensuring cables are intact, connections are tight, and the system as a whole is in good working order can prevent unexpected hitches in performance. Consider it a bit like a winter coat for your system – making sure it’s ready to face the elements.

Mind the shadows

With the sun hanging low, shadows can become more of a performance pest than in the summer months. Keep an eye on trees, buildings, or other structures that might cast longer shadows over your panels. A bit of strategic trimming or planning can help minimise these shadowy intruders.

Consult the experts

If you need help deciding how to optimise your solar panels for winter, reaching out to a professional can be a good idea. They can offer personalised advice tailored to your specific setup and location, ensuring you’re squeezing every bit of energy out of those shorter days.

By following these tips, you can help ensure that your solar panels aren’t just surviving the winter but thriving through it. So, while the weather outside may be frightful, the efficiency of your solar panels can still be quite delightful.

Solar Battery Storage: The Solution

Most homes use more energy at times of the year when there are fewer hours of daylight, so solar panels generate less electricity. An easy way to get around this problem is to add a solar battery system to your solar panels. You can get a new battery even if you have existing solar panels. This game changer is like having a secret stash of sunshine ready to light up your home even when the panels are off-duty.

Storing Sunshine for a rainy (or snowy) day

Imagine capturing the summer’s bounty of sunlight and tucking it away, ready to be unleashed on a dreary winter day. That’s what solar battery storage does. It holds onto the excess energy generated by your panels during sunnier times, which you can then use when the production dips, be it due to cloud cover, shorter days, or a snowflake party on your roof.

Evening out the peaks and valleys

One of the quirkiest things about solar energy is its ‘here today, gone tomorrow’ nature. Your panels might be basking in sunlight one minute and then find themselves under a cloud the next. Solar battery storage smooths out these fluctuations, providing a steady stream of power when you need it. It’s like having a buffer against the whims of the weather, ensuring your home has a consistent energy supply.

Energy Independence and lower bills

With solar battery storage, you can wave goodbye to worries about peak electricity rates or power outages. By storing surplus energy, you’re less reliant on the grid, leading to lower electricity bills and a comforting sense of energy independence. During winter, when energy demands can spike, having your own reserve can feel like having a cosy blanket of security wrapped around your home.

A step towards a greener future

Beyond the practical benefits, solar battery storage represents a stride towards a more sustainable and self-sufficient lifestyle. By maximising the use of renewable energy, you’re not just keeping your home powered; you’re contributing to a larger movement towards reducing reliance on fossil fuels and lowering carbon emissions. It’s a way to make every day Earth Day right from the comfort of your home.

So, as you see, solar battery storage isn’t just an add-on; it’s a transformative element that elevates the entire solar energy system. It turns your solar panels from daytime energy dynamos into round-the-clock power providers, ensuring that no drop of precious solar energy goes to waste. With solar battery storage in your corner, you’re ready to tackle whatever the weather throws your way, all while taking a bold step into a more sustainable future.

The bright side of solar panels

  • You can save money on your energy bills over time.
  • You will be championing the environment and reducing your carbon footprint.
  • Solar panels are great at producing power, but they don’t like to shout about it; they are entirely silent.
  • Claiming your energy independence, you will become freer from the national grid. This means more predictability in your energy bills.
  • Solar panels are low maintenance, so they do not need checking on 24/7.
  • You can sell excess electricity via the Smart Export Guarantee (SEG).

The cloudy days of solar panels

  • The upfront cost of getting solar panels can be a bit of a gulp moment. But think of it as an investment in your future.
  • Solar panels need their space to shine – literally. You’ll need a good chunk of roof real estate that gets plenty of sunlight.
  • You will need a storage battery to store electricity for use at night; this is an additional cost.
  • Not all roof types are suitable. Ideally, your roof should be facing southwards at a 30-45 degree angle – although east and west-facing solar panels can work well too.
  • You will generate less electricity in cloudy weather.

The advantages of solar panels are significant, making them a wise investment if the initial cost is within your budget. On average, households with solar panels enjoy annual energy bill savings of £537 (Source, The Eco Experts, 2023).

Moreover, if you decide to share some of that solar love back to the grid through the Smart Export Guarantee (SEG) – you could pocket an extra £159 every year (Source, The Eco Experts, 2023). All while doing your bit to cut down carbon emissions and make our planet a happier, greener place.

However, it’s important to note that solar panels require considerable space. So, if your roof isn’t big enough to catch the rays needed to power your home, you’ll still need a bit of help from the grid. Nonetheless, any reduction in grid dependence is a positive step towards energy independence.

Finally, solar energy production is limited to daylight hours. To use solar power at night, consider getting a storage battery. These batteries typically cost around £4,500 and have an average lifespan of 12.5 years, meaning you might need to purchase two during the life of your solar panel system (Source, The Eco Experts, 2023).

when is the break even point with solar panels?

In the UK, the typical break-even time for solar panels is 11 – 15 years (Source: Greenmatch, 2024). However, various factors influence this, such as installation costs, the export tariff, energy consumption, and current electricity prices.

System SizeSystem CostAnnual SavingsBreak Even Point
3 kW£7,000 – £8,000£51514 years
4 kW£9,000 – £10,000£77012 years
6 kW£12,000 – £13,000£1,17511 years

However, your location affects your break even point. Sunlight varies across the UK, meaning solar panels in some regions will produce more energy than others. As a result, the time it takes to recoup your investment – the break-even point – differs from one area to another. Check out how each region stacks up below.

In the UK, there’s a nifty way to make going solar even sweeter for your wallet, thanks to solar panel grants like the Smart Export Guarantee (SEG). The SEG is a government-supported initiative that launched in January 2020. It’s pretty simple: if your solar panels are basking in the sun and producing more power than you need, you can sell the extra juice back to the national grid. You’re basically getting paid for being eco-friendly!

The cherry on top of your solar adventure is the long-term savings, especially with the SEG giving you a financial boost. Over 25 years, you could be looking at savings between £13,900 and £30,750. That’s a lot of extra cash in your pocket, all thanks to your decision to go solar and the SEG. The exact amount you save will depend on your setup and the tariff you’re on, but either way, it’s a win-win.

More information about the Smart Export Guarantee can be found in this guide on Ofgem’s website.

how much money will you save with solar panels?

Your solar panels will generate electricity you can use at home, allowing you to buy electricity from the grid. This will save you hundreds of pounds per year, and it gets even better. Below is a table showing the savings you could make over 25 years on a SEG tariff.

*The figures in this graph are calculated based on the national average household energy consumption (Greenmatch, 2024), the example SEG tariff rate (5.5p/kWh), and the current price of electricity (Greenmatch, 2024). The graph makes a broad estimate, and figures may vary according to the size, type, and quality of the solar panel system, as well as export tariffs.

will solar panels become a better investment in the future?

Yes, because electricity will become more expensive and solar panels will get cheaper, but you should install solar panels sooner rather than later. Here’s why…

The Eco Experts (Source, 2023) have worked out that if the cost of solar decreases from their current rate by 24.7% by 2030 and 45% by 2040 (based on government data), by 2025, you would be paying 59.9% less than you would if you bought solar panels today.

However, according to the Climate Change Committee, the cost of electricity is high and only rising. By 2030, consumers’ electricity costs will increase by 24%. That means that every year you’re not using solar panels to reduce your intake from the National Grid, you’ll be paying higher and higher electricity bills.

To put this into perspective, the average three-bedroom household could save around £1,000 on the price of solar panels by waiting until 2030 – but will have paid £628 more in electric bills and missed out on £4,145 in solar power savings. Overall, you would lose £3,587 by waiting – and that’s without even factoring in the Smart Export Guarantee. Therefore, it is a better idea to buy solar panels now and start saving money straight away.
