Promising new solar panel technology

This new method for making solar panels looks promising.

Next generation, pretty cool stuff. I wish I had those panels now.

Perovskite cells and modules on an upwards trajectory.

My 5.2 solar PV is well and truly paid for. Looking closely to see if I can add more or if need be replace existing with 10 to 20 system. Every mm I can fit on the roof this time. ROI for business self use is sooo easy to work out. I am not a feed in person at work except when we are closed.

Thanks for the links. With Cost per Kwh reducing significantly the ROI is so much better.

Another factor to consider is if the connection from house to street is up to standard for the amount of solar you might be trying to put back out to the grid. Expert advice is ours is not good enough and needs upgrading. We're working through upgrade proposals now, as also want to get some other work done.

I have found this website (PVEL | Bankability Testing for the Solar Industry (https://www.pvel.com/)) that publishes test results of many different modules. I have downloaded a series of reports from the previous few years and can see a pattern of a few manufacturers who get the best results over the years and must be able to produce good modules. There are so many claims out there and so many modules to choose from.

Edit: Just read your post DM about new utility connections etc. Your inverter may be fine but it is interesting to note, the same organisation has recently started testing inverters and I think their first report is also avilable now. Aimed at industry but still may give a good heads up on grid connected inverter reliability.
