Is anybody using monocrystalline solar panels???? Are you satisfied with their performance when they are subjected to shaded or dirt conditions?
Presently I have 4 each 150 watt polycrystalline solar panels mounted onto my rear hardtop. They perform well and satisfy all my expectations providing 24 amperes charging current to my batteries when away from our dock. But poly panels are outperformed by mono panels and of course, monos have their own issues.
When I first installed my panels some 3-4 years ago my reasoning at that time led to the poly over the mono primarily because the current from a mono is reported to drop to nothing if any part of the panel is shaded or dirty (think gull poop).
OK, with all that history stated, I am thinking of adding another two panels from Hetech onto the top of my new hardtop that covers the helm. The unit costs difference between similarly rated panels is about 10% which is not much considering I am only looking to add 2 panels. Further, the cost impact is offset by their higher efficiency.
I am looking for user feedback to help me make a decision should I move ahead with a purchase.
Thanks--
