10 Things You Need to Know Before Getting Home Battery Storage Installed

As energy prices rise and concerns about sustainability grow, more homeowners are turning to battery storage as a smart way to take control of their energy use. Whether you’ve already invested in solar panels or you’re looking to make the most of off-peak tariffs, a home battery system can be a powerful tool to reduce your energy bills and increase energy independence.

At MAC Renewables, we’ve installed hundreds of these systems across the Midlands. But before you dive in, there are a few key things you should know. Here’s our top 10 list—based on real-life installations, hands-on experience, and plenty of hard-earned lessons.


1. Know Your “Why”

Are you looking to store excess solar energy, reduce reliance on the grid, use cheaper off-peak energy, or gain backup power in case of an outage? Your motivation will help define the right system for your home.

2. Solar or No Solar?

Already have solar panels? We’ll need to know how big your system is and how much excess energy you typically export. That’s the energy you could be storing for nighttime use. No solar? No problem. You can still benefit by charging your battery using cheaper overnight tariffs.

3. Get Your Smart Meter Ready

Smart meters are essential for unlocking the full benefits of a battery storage system. Without one, it’s difficult to track, control, and optimize your energy use effectively.

4. Wall Space is Prime Real Estate

Battery systems, especially wall-mounted ones, need room. A neat 2m wide by 2.5m high space can be ideal for installation and future maintenance. Good ventilation and clearance from flammable materials are also important.

5. Compatibility with EV Chargers

If you own or plan to buy an electric vehicle, make sure your battery and charger are compatible. A mismatch can lead to your EV draining your home battery unintentionally.

6. AC or DC Coupling?

Most retrofit installations use AC-coupled batteries, but if you’re adding solar and batteries together, a DC-coupled system could be more efficient. We’ll help you choose the right configuration based on your goals.

7. Backup Power Options

Some systems, like the Tesla Powerwall, offer whole-house backup power. Others, such as MyEnergi Libbi, offer essential circuit backup only. If you’re in an area prone to outages, that backup capability might be a game-changer.

8. Internet Connectivity is Essential

Whether it’s Wi-Fi or hard-wired Ethernet, battery systems rely on a stable internet connection for monitoring, software updates, and participating in smart grid schemes.

9. Smart Tariffs & Grid Interaction

With tariffs like Octopus Flux and platforms like GiveEnergy’s “GiveBack” scheme, you can earn money by discharging to the grid during peak times. It’s a smart way to reduce your bills—and support the energy network during demand surges.

10. Planning for the Future

Whether it’s an EV charger, heat pump, or future extension, we always recommend installing a consumer unit with room to grow. We’ve seen too many homes with a tangle of mismatched units added over time. Future-proof your home from day one.


Real Installations, Real Insights

We’ve fitted a range of systems—from SolaX with full backup to GiveEnergy All-in-One systems in detached garages, and Libbi modular setups that integrate beautifully with existing MyEnergi ecosystems. Each system has its strengths, and our job is to match the right one to your home, lifestyle, and energy goals.

Thinking of putting your battery in the loft? Think again—weight, fire safety, and accessibility all make it a less-than-ideal location. We’ll guide you through smarter alternatives that are safe, practical, and scalable.


Next Steps

Before we quote, we’ll ask for a few key details:

  • Your electricity usage (smart meter data helps!)
  • Existing solar setup (if any)
  • Preferred battery location (with photos)
  • Main fuse size and consumer unit details

To make this process easier, call us our team of experts to guide you through the process and book a site survey.

Solar Panel Maintenance: Expert Advice from MAC

Written in collaboration with Anthony Smith, Director at MAC Renewables


Why Solar Panel Maintenance Is Non-Negotiable

Solar power may be renewable, but the technology behind it still requires nurturing. Solar panels function at their best when they’re clean, clear of debris, and electrically sound. Without maintenance, panel degradation accelerates, often silently, as energy output dwindles and performance dips beneath your expectations.

Neglect can translate into significant financial loss over time—something no property owner wants to deal with when energy prices are on the rise.


What We See in the Field at MAC Renewables

“One of the most common things we see on UK rooftops is avoidable damage—from nesting birds, blocked drainage around mounting brackets, or even inverter errors that go unchecked for months,” says Anthony Smith, Director at MAC Renewables.

“A quick inspection could have prevented most of these issues. We recently serviced a commercial client’s system that had dropped 30% in performance over two years. One callout and a thorough cleaning later, they were back to full output.”

Anthony and his team have maintained hundreds of residential and commercial solar systems across the UK, and their field experience makes one thing clear: preventative care beats emergency repairs every time.


How Often Should You Service Solar Panels?

Solar panels don’t need attention every week, but they do need consistent oversight to ensure optimal efficiency.

Anthony’s Maintenance Rule of Thumb

“Treat your solar system like you would your car. You don’t wait until it breaks down to book a service. For us, annual servicing is non-negotiable—and in coastal or rural locations, annual checkups are better.”

MAC Renewables’ Service Schedule:

  • Residential Systems: Annual servicing minimum
  • Commercial Installations: Bi-annual servicing
  • Off-grid or battery systems: Every 6–9 months

Homeowners should perform quick monthly visual checks, especially after storms or high pollen periods.


What’s Included in a Solar Panel Maintenance Plan?

A properly structured maintenance plan doesn’t just clean your panels—it audits your entire system, ensuring each component operates within safe and efficient parameters.

What MAC Renewables Includes in Every Service Call:

  • Visual Survey – Check for physical damage, loose cabling, corrosion
  • Electrical Testing – Measure voltage drop, output variance, and resistance
  • Inverter Diagnostics – Scan for software faults or internal errors
  • Panel Cleaning – Deionised water rinse and soft brush scrubbing
  • Thermal Imaging (if needed) – Identify hotspots or hidden microfractures
  • Documentation – Performance report and maintenance certificate

“We always give our clients a post-service performance breakdown,” Anthony explains. “It’s not just about cleaning—it’s about proving your system is operating at its full potential.”


How to Clean Solar Panels

Cleaning solar panels is trickier than it looks. MAC Renewables often receives emergency calls from homeowners who used harsh chemicals or abrasive sponges, scratching the surface glass or damaging the coating that boosts solar absorption.

Anthony’s Top Cleaning Tips:

  • Always use purified or deionised water to avoid limescale buildup
  • Soft-bristle poles only—avoid anything with steel or plastic ends
  • Never clean in full sunlight as thermal shock may crack glass
  • Don’t walk on your panels—this can shatter internal wafers or microfracture the glass
  • No pressure washers—ever. Even a “low setting” can breach seals and introduce moisture

“The best time to clean? Early morning before the sun gets too strong, or in the evening after the panels cool down.”


Signs Solar Panels Need Attention

Catch the red flags early, and you can avoid 80% of the major issues MAC Renewables typically encounters.

Anthony’s Top Red Flags:

  • Sudden output drop in your monitoring app
  • Inverter flashing red or showing error codes
  • Unusual shadows or hot spots in drone or thermal scans
  • Bird nesting activity or scratching noises under panels
  • Debris accumulation that doesn’t wash off with rain

“If your system output drops 10% or more with no change in weather patterns, give us a call,” says Anthony. “That’s often the first sign something’s wrong.”


DIY Maintenance vs Professional Servicing

Some aspects of solar care can be done yourself—but there are limits.

DIY Tasks You Can Do:

  • Visual inspections
  • Basic debris brushing (from the ground only)
  • Monitoring output via your solar app
    Trimming nearby trees

Leave These to the Experts:

  • Inverter diagnostics
  • Electrical testing
  • Roof mounting inspection
  • Pest-proofing or nesting removal
  • High-access cleaning on pitched roofs

“We’ve had homeowners short-circuit their entire system by trying to fix a cable themselves,” says Anthony. “It’s not worth the risk.”


Common Solar Panel Problems (and How to Prevent Them)

Over the years, MAC Renewables has documented the most frequent solar issues in UK systems. Here are their findings—and how to prevent them.

IssueCauseSolution
Bird nestingGaps under panelsInstall bird mesh barrier
Inverter faultsSoftware glitch or surgeAnnual firmware updates and inspection
Broken connectorsUV damage or pest nibblingReplace with UV-rated, rodent-proof wiring
Algae or lichen growthMoisture buildup on frameGentle biocide application (pro only)
Panel hotspotsDirt buildup or internal microcracksThermal scan and panel replacement

Seasonal Maintenance Tips for Maximum Solar Yield

“Each season brings a new threat. Solar owners should prepare for that shift in advance,” Anthony advises.

Spring & Summer:

  • Wash off spring pollen
  • Cut back vegetation casting shadows
  • Inspect for nesting under panels

Autumn:

  • Clear away leaves and moss buildup
  • Check all cabling is secure before storms hit
    Inspect waterproof seals

Winter:

  • Monitor output for snow obstruction
  • Avoid using hot water to melt snow
  • Inspect for frost damage in exposed cabling

“We’ve found that most winter output issues are due to snow sticking to dirt. Clean panels shed snow faster.”


Costs of Solar Panel Maintenance in the UK

According to MAC Renewables’ 2025 rate card, here’s what you can expect to pay:

Service TypeEstimated Cost (2025)
Standard Annual Service£125 – £175
Full Electrical Diagnostics£250 – £325
Professional Panel Cleaning£95 – £180
Emergency Callouts (24/7)£150 base + time
Bird Mesh Installation£200 – £400

“The biggest cost isn’t the service—it’s the savings you lose by ignoring it. Clients we service annually save more on energy than the service costs.”


How Maintenance Affects Warranty and Insurance

“We’ve had warranty claims rejected because the client couldn’t prove they maintained the system,” Anthony shares. “It’s a painful lesson.”

To Stay Covered, Always Keep:

  • Service reports
  • Photographic evidence
  • Cleaning logs
  • Technician certifications

Insurance providers may also require proof of regular servicing to pay out for storm or fire-related claims.


How to Make Your Panels Last 30+ Years

While solar panels degrade naturally over time, they don’t need to become obsolete. At MAC Renewables, several clients still operate panels installed over 25 years ago—at 80–90% original efficiency.

Anthony’s Longevity Checklist:

  • Stick to your maintenance schedule
  • Upgrade inverters every 10–12 years
  • Keep panels cool and free of shade
  • Seal roof penetrations and cable entry points
    Use quality parts—don’t skimp on connectors or mounts

“Solar systems are like any engine—treat them right, and they’ll last well beyond their warranty.”


Frequently Asked Questions

Do I need to turn off my panels to clean them?

“No—but if you’re doing anything electrical or near the inverter, absolutely shut down the system. When in doubt, call your installer.”

Is bird mesh really necessary?

“In urban areas with lots of pigeons? 100% yes. It’s one of the most requested services we offer.”

Can storms damage my solar panels?

“High winds can dislodge frames if not properly secured. We always inspect mounting systems during service visits.”


Final Thoughts from Anthony Smith

“Solar isn’t just plug and play—it’s a living system that interacts with your roof, your weather, and your home. Maintenance isn’t just good practice—it’s smart ownership.

At MAC Renewables, we believe in building long-term relationships with our clients, because solar should be saving you money, not causing headaches. Stay proactive, stay informed, and let us help you protect your investment.”

Solar Panel Installation: How are solar panels installed?

As energy costs soar across the UK and the demand for sustainable solutions grows, solar power is becoming an increasingly effective way for homeowners to cut energy costs by up to 80% whilst also reducing their carbon footprint too!

When it comes to having a solar panel installation, the process generally falls into three key stages; having a  survey at your home with a solar panel system designed around your specific needs, acquiring the necessary permits and equipment, then last but not least the installation and commissioning of the solar panel system so it can start saving you money. 

MAC Renewables specialise in not only solar panel installations, but battery storage systems and air conditioning too! MAC provide high-quality installations tailored to your individual needs and with solar panel installations taking around 2-3 days to complete, you can start saving fast!

Read on to discover more about how solar panels are installed, how they work and the many ways they can benefit you!

How Are Solar Panels Installed?

The installation of solar panels typically involves three key stages, which begin with;

1. Site Assessment and Solar system design

Your solar installation journey will begin with a site survey to assess your energy needs, property layout, and roof suitability. This survey will include an energy audit and shading analysis too, which will ensure your solar panel system design will align with your specific energy requirements and maximise energy production. With your survey complete, a MAC Renewables specialist will provide you with a quotation that includes a customised system design and a cost analysis that will also highlight potential savings and your return on investment. 

2. Securing Permissions and Solar Equipment

Once you decide to go ahead with your installation, that’s when the team at MAC Renewables will send your DNO (Distribution Network Operator) application for approval. This process can take up to 11 weeks but is very important for both regulatory compliance and safety too. In the meantime, all the equipment needed for your installation from solar panels to inverters or even battery storage units will be procured and prepared in readiness for your upcoming installation. 

3. Solar Panel Installation and System Setup/Commissioning

Once all applications are approved and your equipment is ready, MAC’s skilled installation team gets to work. The first step is to set up any required scaffolding before mounting the solar panels and running the required wiring to the inverter. With the solar panels and inverter connected, the next step would be to connect any battery storage and integrate the system with the property’s electrical grid. Before activating your system, MAC conductcomprehensive testing to verify that all components are operating correctly before taking your solar panel system live and connecting it fully to the grid.

How Do Solar Panel Systems Work?

Whether you have solar panels installed or are still considering an installation, having an understanding of how they work also can help you make an informed decision on whether they are right for you. Ultimately the entire process is underpinned by how the energy is captured and how it is converted into useable electricity

Solar Energy Capture

Solar panels harness sunlight and convert it into usable electricity through a process called the photovoltaic effect. When sunlight hits the solar cells, it excites electrons within the cells, generating DC current electricity. The more sunlight the panels receive, the more electricity they can produce, although this DC electricity needs to be converted into AC current to be compatible with home electrical systems. 

Solar Energy Conversion

In order to make the energy generated from solar panels usable, the inverter installed as part of the solar panel system will convert the DC current into AC current. This makes the inverter just as essential as the solar panels themselves as it ensure the electricity produced is safely converted to match the voltage and frequency to match household appliances. 

How much energy does a solar panel produce?​

Just as no household is quite the same, each solar panel system is adapted to the needs of the home and so the energy they produce will always vary, although it is possible to make a general approximation so you have a clearer idea as to what to expect. 

As a rough average, a single solar panel in the UK can generate around 300kWh of electricity per year, although this will always vary due to factors ranging from the angle of the roof to the strength of the sunlight itself. As most households will have between 10-12 solar panels with their system, you can expect around 3000-3400kWh to be generated annually. With a solar panel setup like this, you can expect the energy generated to cover around 70-90% of your annual electricity use for the entire year! 

It’s important to remember that if you also have battery storage, you can maximise the use of the electricity you generate even after the sun sets as any additional energy generated during the day will be stored for use overnight. Similarly, even without battery storage, you can export any excess electricity you generate back to the grid for a discount off your remaining energy bill too. 

With modern solar panels being around 20% efficient, it may sound low in comparison to the high efficiency you can expect with heat pump technology, although the main reason for this is because of the amount of heat also provided by the sun. A large amount of the light energy solar panels receive from the sun also is coupled with heat energy, which isn’t quite as useful, although with the vast amount of sunlight available this does not particularly impact solar panels from generating energy.

Did you know?

As a general rule, you do not need planning planning permission for solar panels. Usually you will only need planning permission if the building is listed, in a restricted area or if the system is for commercial use.

7 Smart Ways to Maximise Your Solar Battery’s Lifespan and Efficiency

Solar batteries are the heart of any off-grid or hybrid solar system, storing energy for when the sun isn’t shining. To get the most out of your investment, you’ll want to keep them running efficiently and extend their lifespan as much as possible. Here are seven smart, actionable tips to help you do just that.

Keep Them at the Right Temperature

Heat is a battery’s worst enemy, while extreme cold can slow performance. Aim to store your solar battery in a cool, shaded spot—ideally between 15°C and 25°C (59°F to 77°F). different manufacturers will have different requirements, Avoid garages that turn into ovens or freezing basements. A well-ventilated space or even a temperature-controlled enclosure can work wonders like indoors.

Avoid Deep Discharges

Draining your battery completely stresses its cells and shortens its life. Most solar batteries (especially lithium-ion) thrive when kept above 20% capacity. Set your system to stop discharging before it hits rock bottom—check your battery management system (BMS) settings to enforce this.

Charge Smart, Not Hard 

Overcharging is just as bad as over-discharging. Use a charge controller tailored to your battery type to prevent overvoltage. For lithium batteries, aim for a charge level of 80-90% rather than pushing to 100% every time—it reduces wear and keeps efficiency high.

Match Your Usage to Capacity 

Oversizing your battery slightly for your energy needs can reduce strain. If you’re constantly maxing it out, it’ll age faster. Calculate your daily consumption (lights, appliances, etc.) and ensure your battery’s capacity exceeds that by at least 20-30% for breathing room.

Clean and Check Connections 

Dust, corrosion, or loose cables can sap efficiency and overwork your battery. Every few months, inspect terminals for buildup, wipe them clean with a dry cloth, and tighten any loose connections. It’s simple maintenance that pays off, make sure to use caution when checking the terminals. 

Update Your System Software

0Many modern solar setups come with firmware or apps to optimise performance. Check for updates from your manufacturer—they often tweak algorithms to improve charging cycles or energy distribution, squeezing more life out of your battery.

Cycle with Care

Batteries degrade with each charge-discharge cycle, so use them wisely. Shift heavy energy use (like running big appliances) to daylight hours when solar panels can power them directly, sparing your battery unnecessary cycles. It’s a small habit with a big impact.

By following these steps, you’ll not only stretch your solar battery’s lifespan but also keep it humming at peak efficiency. A little care goes a long way—your wallet and the planet will thank you.

New Home Heating Systems: How Will New Homes Be Heated After 2025

What is The UK’s Gas Boiler Ban?

So, if you haven’t already heard, the UK government are planning to ban gas boiler installations in new build properties from as early as 2025. This is to help meet net zero carbon targets, with the burning of natural gasses one of the most significant contributors to emissions on a global scale. The proposal would see new homes fitted with alternative heating systems like heat pumps or electrical heating systems. Existing homes would also need to replace their gas boilers with more eco-friendly options upon failure of their current heating devices. With gas boilers remaining a staple heating solution in homes for decades, we know it might be difficult to know where to begin. There are several different types of home heating systems homeowners can consider and we’ll look at some of those options within this blog.

Home Heating Systems: How New Homes Could Be Heated After 2025?

Heating and Cooling Systems (Air Conditioning)?

A modern type of home heating system that has been growing in popularity in recent years is dual heating and cooling systems, also known as air conditioning systems. Forget the hassle of owning and maintaining two separate devices and embrace the newfound benefits AC units provide. They work by taking external air from either outside or within the ground, depending on your model, and absorbing the heat from this before pumping it into your home. There are many advantages that come with air conditioning units, one of which is their 350% efficiency rating. This further translates into a significant cost-benefit ratio, making them cheaper to run than traditional gas heating systems.

Biomass Heating for Homes

New biomass heating systems provide an eco-friendly way to heat your home using sustainable organic materials. Wood pellets, chips and logs, all usually locally sourced, are burned in a biomass boiler or stove to heat water. This water then circulates through radiators or underfloor heating to warm up your home. As plants and trees regrow, they absorb back the carbon dioxide released during this burning process, making biomass heating a lower carbon alternative than burning natural gasses. Although the upfront costs for a biomass boiler can be high, there are several government incentives, like the Renewable Heat Incentive, to help offset this. Biomass fuels also tend to be relatively cheaper than oil or propane.

Home Electric Heating Systems

Electrical home heating systems, like electric boilers, simply convert electrical energy into heat energy to provide warmth during the colder months. They are extremely energy efficient, as all the electrical energy converted is used for heat. Although they are often said to be 100% efficient, a small percentage of this energy is lost during the transfer process. This however is minimal compared to traditional gas heating systems and even the new condensing boilers. However, the downside is that electricity costs more than gas and lacks the leveraging of free environmental heat as heat pumps do. Although new smart electric heating systems help increase efficiency and have lower running costs, this is still substantially higher.
