Flat batteries are at best a nuisance and at worst a hazard but can be easily avoided by using the abundant and natural power of the sun. Solar energy gives you the convenience of power being available for engine starting, lighting and other low energy appliances. Once installed the photovoltaic (solar) panel works quietly and efficiently at recharging without any effort on your part.
The new Spectra range of solar panels are ideal for maintaining and replacing natural discharge in 12V deep cycle batteries in leisure applications. In wintertime you can avoid the trouble of taking batteries home for topping up by installing one of the Spectra range.
In the UK we recommend a minimum ratio of a 10W solar panel to a 100Ah battery, daily this would generate up to 3Ah. In summertime this increases up to a potential of 21Ah daily, typically enough for a summer weekends cruising needs for basic lighting etc. Most importantly youll arrive to a battery that is not flat!
For larger batteries simply scale up on the same basis, ie 20W for 200Ah as a minimum. For faster replenishment of the battery in applications where there is greater power consumption use larger or multiple solar panels than the minimum recommended.
