For those people who have a large power use or who cannot afford to immediately purchase a solar or solar/wind hybrid power system, a generator/hybrid power system may be a viable alternative, rid power system may be a viable alternative.

Initially the power system may consist of just a petrol or diesel generator with power only available while the generator is running, a second stage where a battery bank and inverter/charger is added will provide the convenience of 24 hour power, reduce fuel and maintenance costs and reduce noise pollution. Later as finances allow, solar modules or a wind generator can be added to the system to reduce generator run times and costs further still. Marine and RV use. The sizes recommended for marine usage are generally either the 12 or 22 watt unit.

The choice between the two is generally taken on your battery load requirements and the expected frequency usage of the vessel. Our recommendation is as follows: 12W module-used generally where loads are only for lights, radios and pump, with a frequency of usage of approximately once a month in winter and once fortnightly summer months. 22W module-used where loads are heavier, with weekly use in the summer and fortnightly use in the winter months.

The smaller 2W an 5W modules are ideal where the vessel/vehicle is left fore many months, the smaller panels will ensure the battery is maintained without excessive gassing of the batteries.   These solar panels are also useful where the battery is simply required to maintain its state of charge, for protection against self discharge.
