Glenergy portable solar systems offer practical solutions for many applications even in the most remote locations. These systems are perfect for lighting or power at camps, cottages, boats, trailers and much more. Depending on the amount of power you will need we have a variety of systems for you to choose from, using different sizes of batteries and solar panels. Our smallest battery, the 9 Ah has 54 Wh of useable energy when fully charged. This, for example, could run a 3 watt LED bulb for 18 hours. The largest battery in our packaged systems is the 100 Ah model with 600 Wh of available energy. This could run a 40 watt TV (15" flat screen) with a 30 watt DVD player for almost 9 hours. The size of panel chosen depends upon how fast you need to charge the battery. A 10 watt panel will need about 2 full sun days to charge the 9 Ah battery and the 135 watt panel would need the same two days to charge the 100 Ah battery.
