I need to install at least one solar panel to trickle charge 2 domestic batteries - I’d appreciate any advice on the best route for the cabling. I have the choice of installing a semi-flexible panel on the deck under the boom and in front of the sprayhood or to install on the sprayhood itself (my preference being the former). The two domestic batteries are located inside the engine cowling. I’ve unscrewed a couple of ceiling panels but this raised as many questions as it answered. Any advice much appreciated.
