Why is Regular Solar PV Inspection Important?

Solar panels are becoming an increasingly common sight on rooftops across the UK and there are any number of companies that can offer a quick and easy installation for you. In a matter of weeks, you can be saving money on your electricity bill!

However, once your installation is complete, it’s really important to keep on top of the inspection and maintenance routines to make sure it’s functioning both safely and efficiently. Failing Solar Photovoltaic Panels not only will lose you money and missed opportunity, it can in extreme conditions present a fire hazard – Read here about a Solar Panel fire at a Walmart Store

Is it important to inspect Solar Panels regularly?

One of the first checks you’ll want to perform is a post installation assessment to make sure that everything has been installed correctly and that there are no errors. Carrying this out within a short time from your panels going live means that you can call your installation team to rectify any faults discovered within the warranty period. It also means that you will be saving the maximum amount on your electricity bill as soon as possible after your solar investment!

Obviously, you should order an inspection if you can see signs of damage to your panels, that’s pretty clear.  However, many faults that are possible for solar panels to suffer from are invisible to the naked eye and that is where thermal images can be of great value.  Using our state-of-the-art thermal camera on one of our drone fleet and, flown under the right conditions, we can quickly and easily carry out a complete system health check in a matter of minutes. Any problems are clearly highlighted on the resulting images and, if you then require corrective action, you can give those images to your maintenance company, and they can complete repairs in a targeted fashion.  That means that you don’t incur the expense of having people up on your roof unless they really need to be there (and minimise chances of any damage to your roof during the process).

Where you and your neighbours all have solar panels, it can be cost effective to come together and organise your solar panel inspections.  Drone Media Imaging can offer discounts where this is the case so you can all benefit from the savings.
