What is the best height from which to thermally survey solar PV?

by admin | Mar 12, 2019 | Uncategorized

If you are looking to commission a survey of solar PV, then a question you may ask contractors is ‘what height do you fly at’ to try and get a bearing on what data may be delivered, but to be able make an informed judgement you will need to know more. What is the best...

This image shows PV modules that have a failed bypass diode. Bypass diodes are installed in modules to protect the PV cells from damage during shading. There is generally 3 of them within the junction box, each protecting a string of 20 cells which is why you can...

Who should be responsible for Solar PV Thermography testing?

by admin | Feb 22, 2018 | Uncategorized

Traditionally Solar PV Thermography testing has been within the remit of the O&M (Operations&Maintenance) department. Testing the modules manually is very laborious so a pre-agreed percentage, of 20% for example, would be arbitrarily tested. Nowadays,...

When is the best time for Solar PV thermal inspections by UAV?

by admin | Feb 19, 2018 | Uncategorized

An irradiance level At least 600 W/M2 is needed to inspect Solar PV. This is the amount of energy falling on the surface of the modules, therefore any metering equipment should be placed in the same plane. You can of course obtain some thermal patterns at lower...

3D Modelling with thermal imaging

by admin | Feb 20, 2017 | Uncategorized

By taking 100’s of thermal images and tuning them, it is possible to recreate the subject using photogrammetry. This is a great tool for displaying where heat loss is occurring from a building for example. In the future it would be nice if the model is...
