How to test solar panels

In some cases it can be easy to determine the cause of a reduction in solar output. For example, you won’t need to know how to test solar panels if a nearby tree has grown and is now casting shade on your panels.

In many cases, it isn’t so straightforward. So, let’s go through some ways to test your solar panels.

1. Check your generation meter for a red light

Most generation meters will have some sort of indication light that will let you know instantly if your system is not functioning correctly. Check this during the day when your system should be generating and if it is lit, you may have a problem with a part of your solar system.

2. Look at the figures on your generation meter

Keep a regular record of the figures on your generation meter - doing this weekly will give you a good set of readings to work with. You can then compare the figures (taking into account any shifts in generation that could be attributed to changes in weather) and identify any potential issues.

3. Use an app to monitor generation

You can make the above process much easier by using an app on your smartphone, tablet or computer to monitor your systems output levels. Much of the software designed for this will allow you to see your generation in real time through an easy to use dashboard or display. Having this information at the ready makes it easy to keep an eye on your output and doesn't require you to check the generation meter manually.

4. Compare your actual readings to your quote

Often a solar installer will provide you with an estimation of how much electricity your system is likely to generate. You can compare this with the figures you have collected from your generation meter and any major differences could point to a problem with the system. Bear in mind that the figures may not match up exactly as it is after all an estimation of your systems potential only, not a guarantee.

Still not sure if your solar panels are working?

If you’re still concerned over your solar performance, speak to the installer who fitted your system. It’s a good idea to contact them if you notice any issues when testing your solar panels.

Why is it important to test solar panels?

Simply so that you can get the most out of your investment in renewable energy.

  • Lower electricity bills
  • Reduced reliance on your energy supplier
  • Freedom from ever-rising energy costs
  • A more environmentally-friendly home
  • Increased property value
  • The chance to earn payments through the Smart Export Guarantee

How to maintain solar panels

  • Having them cleaned
  • Arranging a service from a professional
  • Keep the area around them free from branches
  • Regularly monitor their performance

Once they’re working, store energy in a solar battery

Any excess energy generated by your solar panels – there’s likely to be some – will be automatically sent to the National Grid. You can receive payments for this through the Smart Export Guarantee. However, what if you want to hold onto this energy for yourself? Well that can be made possible with a solar battery.

Adding a solar battery to your solar PV system will allow you to power your home with free renewable energy into the night. THis will help to reduce your carbon footprint and energy bills even further. Some models even work during a power cut! Compare the Best Solar Batteries.
