Solar lighting system in our school

[axis11]

If you or your fellow students will do the maintenance, you would want to place the batteries in an accessible location for easy maintenance, watering the batteries, measurements and tests, replacements. You would want to monitor your system so you should place the controller where you can see the indicator lights, display. If the professor or the director will do those tasks, the attic would be a good place for them.

DONT enclose the battery with the charge controller. or its fumes will corrode the internals of the charge controller. in fact dont fully enclose either of them as they both need air flowing around them for cooling. and to disperse the battery fumes.
