☀️ Before & After… because your panels deserve a little TLC too! 😎

Solar panels spend their days outside taking on dust, pollen, bird droppings, pollution and general Cape Town weather. Over time, that buildup can affect how much sunlight reaches the panel surface.
The tricky part? You might not notice it happening. Your system can still be producing power, just not necessarily as efficiently as it could.

A proper module clean helps remove that layer of grime and allows more sunlight to reach the cells. ☀️

And honestly… sometimes you just need to see the before and after to appreciate the difference. 👀

➡️ Swipe to see what a good clean can do.

And yes… that reflection in the after photo? ☁️✨
Those panels are looking much happier!
Regular cleaning is just one small part of good solar maintenance but keeping an eye on your modules can help you spot potential issues before they become bigger problems.

When was the last time you checked what your panels actually look like up close? 👀

🔩 TORQUE MATTERS — AND IT’S EASY TO OVERLOOK

Your PV system is exposed to wind, vibration, temperature changes and the elements every day.
Over time, these conditions can contribute to mechanical connections becoming loose or deteriorating.
That’s why checking mechanical connections and verifying torque where required should be an important part of an annual PV inspection.

It’s a simple check that can help identify issues early, before they lead to movement, damage or more costly corrective work.

☀️ Regular PV maintenance should look at the condition of the complete system, including the mechanical components that keep everything securely in place.

When was the last time your PV system’s mechanical connections were checked? Below images is what happens if not checked

⚡ FROM DETERIORATION TO RESTORATION — WHY ELECTRICAL ENCLOSURES NEED ATTENTION

Your electrical enclosure protects some of the most critical components of a solar PV system.
But what happens when the enclosure itself starts to deteriorate?

These before-and-after images show a DB enclosure that required attention during maintenance.
Exposure to sun, rain, moisture, dust and changing environmental conditions can take its toll over time. Corrosion, damaged surfaces, compromised seals, water ingress and blocked or inadequate ventilation can all affect the condition and protection of the equipment inside.
An enclosure may still be functioning, but that doesn't mean it should be overlooked.

🔎 Regular O&M inspections can help identify:
• Corrosion and deterioration
• Signs of water or moisture ingress
• Damaged seals and enclosure components
• Dust and contamination
• Ventilation issues
• Deterioration that may compromise the enclosure's protective function

The first photo shows the condition we found the DB.
The second shows the result after corrective maintenance.
This is what preventative and corrective maintenance is about , identifying deterioration, addressing it appropriately, and maintaining the integrity of the equipment protecting your electrical system.

At DWS Solutions, our Operations & Maintenance services focus on keeping your solar PV assets safe, reliable and properly maintained throughout their operational life.
Because sometimes, what protects your electrical equipment needs protection too.

🌬️ WHEN WAS THE LAST TIME YOU CHECKED YOUR FILTERS?

It’s easy to look at a solar PV system and focus on the panels, inverters and production figures.
But sometimes, the smallest maintenance task can make a big difference.

Take a look at this filter. 👀
Dust and debris can gradually build up over time, particularly on equipment operating in dusty or harsh environments.

So why does keeping equipment filters clean matter?
❕️Restricted filters can reduce the airflow available for equipment cooling.
❕️Reduced airflow can contribute to higher operating temperatures where the equipment relies on forced-air cooling.
❕️Excessive heat can cause equipment designed with thermal protection to reduce output or shut down, depending on the equipment and operating conditions.
❕️Keeping cooling paths and filters maintained helps the equipment operate within its intended environmental and thermal conditions.

And here's the important part:
A filter doesn't have to be completely blocked before it needs attention.
Regular inspection and cleaning, carried out in accordance with the equipment manufacturer's maintenance requirements, can help keep cooling systems operating as intended.

At DWS Solutions, preventative maintenance is about looking beyond what's immediately visible and making sure the equipment that keeps your solar asset operating is properly maintained.

Because sometimes...
It's not the big things that cause problems.
It's the small things that get overlooked.

🔧 PREVENTATIVE MAINTENANCE: WHAT ARE YOU ACTUALLY PREVENTING

A solar PV system doesn't have to be broken before it needs maintenance.
Solar installations are exposed to heat, UV, wind, moisture, dust and vibration every day. Over time, these conditions can contribute to deterioration, loose connections, corrosion, damaged components and other issues that can affect the reliability of the system.

Preventative maintenance is about finding those issues before they become failures.

During an O&M inspection, we look at the condition of the equipment and identify potential issues such as:
🔍 Electrical connections and terminations
🔍 Cable management and DC/AC cabling
🔍 PV connectors and signs of deterioration
🔍 Earthing and bonding
🔍 Protection equipment and distribution boards
🔍 Inverters and associated equipment
🔍 Mounting structures and mechanical components
🔍 Signs of overheating, corrosion or physical damage

Why is this important?
Because identifying a deteriorating component early can mean a planned repair instead of an unexpected failure.
And when a fault does occur, corrective maintenance is about more than simply replacing the failed component.
It's about investigating the fault, identifying the cause, making the system safe, completing the necessary repair and returning the affected equipment to service.

At DWS Solutions, our focus is simple:
Prevent problems where we can.
Correct them when we can't.
Keep your solar asset maintained.

Because preventative maintenance isn't about fixing what's already broken.
It's about identifying what could become a problem next.

If your solar PV site requires preventative or corrective maintenance, get in touch with DWS Solutions.

Earthing isn't just a green and yellow cable, it's one of the most critical safety systems on any solar PV installation....
28/07/2026

Earthing isn't just a green and yellow cable, it's one of the most critical safety systems on any solar PV installation.⚡️

However, during our Operations & Maintenance inspections, we regularly identify loose earth connections, corroded conductors, damaged earth cables, missing earth bonds, and components that are no longer effectively earthed.

These issues can develop over time due to environmental exposure, corrosion, vibration, maintenance activities, accidental damage, or system modifications.

Why does this matter?
An effective earthing and bonding system provides a low-impedance path for fault current. This helps protective devices operate as intended and reduces the risk of dangerous touch voltages during electrical fault conditions.

If the earthing system is compromised, the consequences can include:
⚠️ Fault currents may not clear promptly or as designed
⚠️ Metal frames and equipment may become energised during fault conditions, increasing the risk of electric shock
⚠️ Protective devices may not operate as intended
⚠️ Equipment may be more susceptible to damage during fault conditions or lightning related events
⚠️ Increased downtime, costly repairs, and reduced system reliability.

The concerning part? Many earthing defects aren't obvious during a routine visual inspection and are often only identified through proper testing. A system can continue generating power while hidden safety defects remain.

That's why Operations & Maintenance is about far more than monitoring system performance. It includes inspecting and testing the earthing and bonding system to verify that it continues to perform as intended throughout the life of the installation.

At DWS Solutions, we believe preventative maintenance is about identifying potential risks before they become failures, protecting both your assets and the people who work around them.

🔎 When was the last time your solar PV system's earthing and bonding were inspected and tested?

Because a reliable solar PV system starts with a safe one.

Cable management doesn't always get much attention... until someone points out the details. 👀

This photo was taken during a recent PV inspection, and there's quite a bit going on.

Some cables are resting on the roof, cables not properly secured or routed, cables are exposed to the elements, the cable tray is uncovered, and there's even a bit of debris on the modules. None of these things necessarily mean a system will fail overnight, but together they can affect reliability, maintenance, and the long term health of the installation.

The best part? Most of these are relatively simple to correct.

🔍 If this was your site, what would you address first?
Or, did you spot something we haven't mentioned?

We're always interested in hearing different perspectives from installers, electricians, and O&M teams. Let's hear your thoughts below. 👇

📉 One Broken Panel Could Be Costing You More Than You Think

It's easy to look at a single cracked or damaged solar panel and think, "It's only one panel, we'll replace it later."
The reality is that a damaged module can have a much bigger impact than most people realise.
Depending on the nature of the damage, it can:
⚡ Reduce the output of the affected string
⚡ Trigger inverter faults or string alarms
⚡ Create hot spots within the module
⚡ Allow moisture ingress, leading to further deterioration
⚡ Become a potential electrical safety risk

📊 Behind the Numbers
The example below is for illustration purposes only. Actual losses will vary depending on system design, irradiance, site conditions, electricity tariffs, the type of module damage, and whether the fault affects only the module or the entire string.

Consider a 100kW commercial solar PV system using 550W modules.
If one damaged 550W module is no longer producing energy, it could result in approximately:
• 3 kWh of lost generation per day
• 90 kWh per month
• 1,080 kWh per year
At an electricity tariff of R3.00/kWh, that's approximately:
💰 R3,240 per year in lost energy value from just one module.

In some cases, the impact can be even greater if the damaged module affects the performance of the entire string or causes the string to trip offline.

The takeaway?
A single broken panel may seem insignificant, but delaying repairs can reduce system performance, lower your return on investment, and increase the risk of more costly failures over time.

Don't let one damaged module become a much bigger and more expensive problem.

Would you replace one broken panel today, or risk paying for its impact over the next year?
