Hi,
I'm in the research and money saving phase of getting a narrowboat.
I was really confused by all the solar panel options, what they mean, how they compare and how bad it will be if I go with flexible ones.
So I've made a simple comparison, basically a fancy spreadsheet.
I hope someone will find it useful, please feel free to let me know and suggestions for improvements.
TL;DR:
Bigger frame panels provide more power per m² and more power per £ spent on them.
This is not true for flex panels to such a degree.
Power per £ is significantly better in frame models.
Frame vs Flex power per m² is about the same (if we ignore angle).
TODO:
Researching and adding a graph of expected efficiency in UK per month (shade/sun) for flat roof and calculation of gains if someone aims panel twice a day.
Adding top down view of boats of different seizes with example roof coverage and possible power gain per type/month.
Have a great weekend everyone.
