Silent solar powerSolar panels are used on sailing boats so that noisy generators are not required. Solar power generates electricity silently without disturbing the quiet serenity of sail power, the only sounds are the wind in the sails and the bow cutting through the blue water.Tough, waterproof and corrosion resistant solar panelsThe solar power used on sailing boats need not be different to land-use solar panels in their function but all electrical components need to be waterproof. The solar panel frames and mountings must be corrosion resistant to prevent attack from the highly corrosive sea spray. If mounted on decks they need to be tough enough to withstand being stood on.Components of a marine solar systemThere are solar regulators designed specifically for marine use, for example those used on solar powered marine buoys, it does not need not be any different to the usual typ proactol es available if it is installed under cover with the battery, but must be waterproof if it is going to be mounted outside with the solar panels.There are no batteries designed specifically for marine use but deep cycle batteries are recommended for daily power storage and use. The term “deep cycle ” means they can routinely be drained to low levels of charge, usually about 30% state of charge (SOG) without any detrimental effect to the battery cells. Deep cycle batteries are recommended whenever power is stored and used on a daily basis as they will last longer than normal vehicle starting batteries, although it is best to use sealed batteries such as absorbed glass matt (AGM ) or GEL batteries to avoid acid spillage in rough weather.Wiring should be marine grade cable with UV resistant insulation. It must be capable of handling the charge current without any significant voltage loss.
