    Charging 12v Battery with Solar Panel?

    I use a small 12v 1.5w Solar Panel to charge my engine battery, quite often it's not powerful enough and the battery loses charge. If I buy a bigger one say 30w, would that still trickle charge (albeit faster) it, or would it damage it? TIA

    Just an idle thought - has anyone any experience of using the DC output of solar panels to directly feed an immersion heater, to avoid the expense and losses associated with an inverter?

If anyone wants to buy it in September let me know! The problem is that the cigarette...
