It’s advised to understand how your Solar panel operates before we can pinpoint our issues. First, be sure to utilize equipment compatible with your 12 Volt Panel if you’re utilizing one. That is a 12V battery, a 12V inverter, and at the very least, a 12V charge controller.

Now verify the wattage of your panel by looking at the back of it. After that, divide watts by volts. Consider the case when you have a 100W Solar panel. And during daylight hours, this will generate roughly 8.33 amps per hour.

Now a typical query is raised. When will a battery be fully charged? Arithmetic is just math. Divide the amps you will use to charge the battery by capacity. Let’s say it takes 8.33 Amps to charge a 100 amp-hour battery. It would take around 12 hours or about half a day.

Why is Your Solar Panel Not Working?

You are now, then? Your panel is defective. To attempt to remedy some of the problems, you must first grasp a few of them. Here are a few of the typical problems that stop solar panels from functioning.

Issues with Low Voltage or Zero  

Ah, a similar issue as the prior one. Keep in mind Ohm’s law. V=IR. I, or current, is also 0 if your voltage (V) is zero. Your solar panel won’t function, either. What makes your voltage zero, then? “Broken Solar Charge Controller” and “Broken Solar Inverter” are the primary culprits. One damaged panel in any solar array may also result in problems with zero voltage if you are utilizing one.

Also, bear in mind that troubles might arise from shade (anything that prevents sunlight from reaching the panel), unclean solar panels, very high temperatures, and malfunctioning panels, all of which will affect voltage.

Issues with Low Amps or Zero

The amp is what keeps your PV system alive. It won’t operate if it’s 0 or extremely low. Why, then, does your panel have no amps? One possibility is an open circuit, often known as defective solar panel wiring. The well-known faults in solar charge controllers are another factor. In essence, your solar charge controller malfunctions and interrupts the current flow. Finally, internal panel flaws will unquestionably result in zero amp troubles. Perhaps your panel was the cause of the issue after all.

Issues With Different Equipment

Make sure you utilize high-quality equipment first. You need a decent solar power controller, a good inverter, & other excellent components for your PV system. The system won’t function if even one piece of your equipment is damaged. Check each piece of equipment, then.

Defective Solar Panel

The Traditional. No matter how hard you try, a defective solar panel won’t operate. Fixing an internal issue is challenging. And nine times out of ten, will be problematic. Fixable issues include loose MC4 connections and junction box issues. But correcting issues like broken panels, odd patterns in panels, and aged panels can be challenging.

Trivial Issues

In addition, several additional little things may need to be fixed for your system. The typical offender is bad wiring. Using mismatched equipment, excessively charging the battery, connecting the battery directly, & other problems are additional factors. If you are familiar with solar panels, you can repair most of them.

How to Diagnose Solar Panel Issues

Since most households install solar photovoltaic panels to save money, checking your power bill is the easiest way to tell whether your panels are functioning. You may tell something is awry if this month’s statement is much higher than last month’s.

Worse, it is only possible to determine your solar output from the most thorough and precise utility accounts. For instance, a steady bill might indicate that your PV system is underperforming and not generating the potential savings it could. This is not to say that you shouldn’t sometimes review your utility bills. However, these assertions cannot reveal hidden issues or assist you in resolving them.

Fortunately, the DIY advice below makes it easy to do away with any uncertainty. These address the most common causes of your solar panels not functioning and the best self-help solutions.

Check The Breaker Switches

Isn’t it annoying when you phone tech support, and they ask you to confirm that the computer you are troubleshooting is connected and turned on? It’s humiliating. However, because a disconnected PC is one of the most common reasons a user’s computer cannot operate, these customer support personnel must ask.

The same is true with breaker switches or the little fuse boxes that control the energy flow in your house. These switches may trip due to surges, errors, and overloads, which prevent solar energy from powering devices or entering the grid. However, returning them to their original form generally takes care of the problem.

Check Any Obstructions

Given that solar panels require direct sunlight to produce energy, it’s critical to maintain your panels clear of everything that might prevent this production, such as:

Trees with recent foliage can obstruct light. In this situation, you may need to prune certain branches.

Dust, trash, and pollen buildup may gradually worsen, blocking sunlight from reaching your PV panels. Here are some free guidelines for properly cleaning solar panels.

Check for obstructions below the panels as well. Nesting mice, birds, and other vermin may harm the parts of your PV system, producing less energy. Therefore, it’s crucial to remove any waste and dirt. In order to avoid repeat infestations, it is also an excellent idea to install a pest guard.

Look Into Your Solar Inverter

PV installations often include the inverter that converts the direct current (DC) power from your solar panels to alternating current electricity for your home’s appliances. Your solar inverter is operating if its green light is constant. And you don’t need to do anything.

Examine Your Solar Meter

Real-time energy production from your PV system is recorded by solar meters. Additionally, this enables you to identify abnormalities by comparing historical production data to the most recent data. Solar meters are sometimes homeowners’ first line of defense against wasted money.

Place Solar Monitoring Systems

Most performance concerns ought to be detectable early if you have a functioning solar meter and remember to check it regularly. But you must bear in mind. Additionally, you must maintain track of historical data to properly contextualize current solar output figures. This kind of care is only sometimes practicable for the typical homeowner.

Run quietly in the background, monitoring the output of your PV system in real time.

Enabling access to this performance information from any computer and mobile device

Examine your past Generation data, the climate in the area, and the output of your neighbors to determine the state of your solar system.

When the output of your PV system deviates from the expected range, send out alarms.

Checking Environmental Issues

Ensure that your solar panel is receiving enough sunshine. Nothing obscures it. Examine the circuit to see if anything is interfering. (Like trees and other natural resources). Ensure your panel is organized and spotless. Also, please check if high temperatures must reduce the panel’s effectiveness.

Verifying the Integrity of the Panel

Check to see whether your panel has any damage. Look for hotspots, odd patterns, or cracking. Also, ensure your MC4 connection is secure, and the junction box is installed correctly. With your panel, you should quickly identify any damage.

How to Spot Issues With Solar Panels Before They Affect Your Savings

The checklist will enable you to fix 80% of solar-related problems. And it’s a good idea to repeat these procedures frequently since, throughout the 20 – 25 years of the panels’ warrantied lifespan, dust collection, bug infestations, and tripped switches were all inevitable.

On the other hand, solar monitoring is the easiest and most hands-off method for determining when and why your solar panels aren’t functioning if you’re concerned about safeguarding your clean-power investment. When correctly configured, solar monitoring can track the performance of your PV system and notify you when action is required.

Frequently Asked Questions

How can you detect when a solar panel is malfunctioning?

Numerous inverters include status LEDs that show how the system is doing. Normally, a green light denotes that everything is in order, an orange light shows that a possible problem has been found, and a red light that flashes denotes that there is an issue with the system.

Why doesn’t my inverter recognize the solar panels?

There is a strong likelihood of no grid supply for the inverter if sufficient light is outside on the panels to produce power, yet nothing is shown on the inverter screen. Verify that all RCDs (Residual Current Detectors) & Miniature Circuit Breakers are in the ON position.

Can you fix a solar panel?

Repairs may be made to minor cracks. The whole panel will need to be replaced if they run through it. Swap out these solar panels as quickly as possible to avoid additional damage.

What damages solar panels?

Solar panels that break are often harmed by weather (hail, wind-related debris). No one would be surprised by damage caused by a tree limb dropping during a storm, but the worst offenders are often much smaller. The glass of solar panels may be blown with twigs, leaves, dirt, and sand.

Can sunlight damage solar panels?

The researchers discovered that the delicate organic molecules on the semi-conducting layer might be harmed by exposure, much to how your skin’s carbon-based cells might suffer from a painful sunburn after a day at the beach.

Final Thoughts

There may be a number of causes for solar panels that aren’t performing as they should. Combinations of internal and external elements may have an impact on the effectiveness and performance of solar panels. The performance of solar panels may be enhanced by swiftly addressing these problems via routine maintenance, optimal placement, and ensuring correct installation. Future developments in solar technology could provide more effective and long-lasting panels, increasing their total efficacy and contribution to the production of renewable energy.
