Whether for weekend, holiday, or daily use, wind and solar power can be used to keep batteries charged in your boat, caravan or motorhome - giving an independent electricity supply without the noise and stench of engines and generators, or the inconvenience of finding mains hook-ups.
Typical loads include: DC lighting, TV, radio, pumps, fans, phones. By using an inverter, 230 Vac appliances such as video, HiFi, microwave, vacuum cleaner, satellite system or computer can be powered.
On vehicles and inland craft, wind generators are best mounted on a hinged mast which is easy to raise when moored but compact when travelling. Seagoing boats often use mounts on deck rails or masts. Separate guyed masts are preferred for caravans. Output is dependent on the openness of the mooring or site and wind conditions, but will generally be greatest over winter months.
Solar systems are perfect if mainly summer use is intended. Solar modules are simply fastened to the van or boat roof using frames which ideally should adjust to catch maximum sun. Usually the higher output industrial panels are appropriate. Non-glass modules are available for decks and vulnerable locations. Output cables are simply connected across the domestic battery via a charge controller which prevents battery overcharge and provides system monitoring. Generally systems can be easily mounted and installed by the user. Alternatively, many boatyards and caravan or RV suppliers can make up fittings or undertake installation.
