Looks good Derrick.
Though just a little clairification. Some
solar panels come complete. The majority how ever come with nothing.
Solar panels come in a variety of nominal voltages mostly 1.5, 3, 6, 12, 18,24, 36 & 48. The most common is 12V - especially for use in camping applications.
So i'll talk about 12V "solar panels". A panel marked as being 12V is actually only nominally 12V its watt rating is gained by mutipling the peak voltage and peak current by one another. Therefore most panels are generally running between 60-80% sometimes higher for a small portion of the day upto 100% of their POWER (watts) rating. P = IxV.
A panel rated at 12V can push out voltages as high as 20 odd volts and so low that they can actually use power from the battery
- therefore you need to regulate your feed from the solar. There are many different regulators out there and I would suggest you talk to a 12V / Solar specialist unless your buying an off the shelf ready to go setup with regulator and everything.
I'm personally looking into a 24V solar setup using 2 x 12 V cells in series through a pulse rate regulator / invertor with UPS function. My fridge runs more efficiently off 24V than 12V and thats about the only thing I use from DC electricity other than lighting and I can get 24V LED lighting easily enough (and in most instances cheaper because of their extencive use in trucks) Also (V)DC - 240VAC inverters run marginally more efficient from 24V because the higher voltage means a lower current drawer for the same amount of power. I can still opperate 12V appliances if needed though as a center tap can be applied to the batteries in series - not the greatest solution but for how often i use 12V it doesnt really matter.
Im using a pair of 12V 100Ah AGM batteries in series for 24V at 100Ah (if i went a 12V system it would be 200Ah @ 12V. All these specs are C20 ratings of the batteries).
The batteries are maintainedusing a PWM charger and the sulfation reverced. the only problem with AGM batteries is that they do swell.
