I am after a 50w solar panel to replace a broken one in a triple folding. The existing one is a Rich Solar RS-M50. The dimensions are 720x540x30. Most are now 35mm thick. If anyone has one they want to sell, or know where I can get one, please let me know. I have tried a number of online suppliers.
May I suggest that it is not "50W" that you need, but a panel that is tha same dimension as the old one.
With increases in efficiency, that maybe 55W now.
Alternatively, it might be just as cheap to buy 2 panels of any size and transfer the hinges and regulator etc.
Should cost about $120.
