2017solar.com - When buying around for a photo voltaic panel battery, you may find basic sorts utilized in storing photo voltaic electricity. The primary distinction between them is that one makes use of an acidic answer and one makes use of an alkaline solution.
Lead-acid batteries are the ones mostly utilized in storing photo voltaic electricity. This is primarily as a result of they're cheaper and may be discovered virtually anywhere in the world.
When buying a lead-acid Solar Panel Energy Storage Battery make certain solely to buy deep cycle batteries as they're made to be discharged on a repeated foundation to as much as 50% of their rated capacity. Shallow cycle batteries, the unsuitable alternative, are solely constructed to provide quick bursts of maximum power. Due to this fact they will deteriorate rapidly if discharged by any more than 20% of their capacity too often.
When utilizing a lead-acid photo voltaic panel battery, make sure you cost it completely after each cycle, otherwise you run the chance it failing on you prematurely.
No matter how widespread its use, however, one important downside to the lead-acid Solar Panel Energy Storage Battery is that its capacity will lessen as the temperature drops, a serious problem in the useless of winter.
Alkaline batteries, then again, work perfectly well in colder climates, as their answer is proof against freezing. The newest of alkaline batteries may be left unattended and the photo voltaic electricity it's storing fully discharged without it affecting their approximate 4,000 cycle lifespan one bit (or 20 years under normal utilization).
An alkaline photo voltaic panel battery will both be fabricated from nickel-cadmium or nickel-iron. Nickel-cadmium is a slight bit more efficient but it's also very bad for the setting, whereas there aren't any identified environmental drawbacks to utilizing a nickel-iron photo voltaic panel battery, though it may be slower to answer a heavier draw.
Any new nickel-iron photo voltaic panel battery you purchase you may must first cycle by way of several instances (in different words: run it completely down and energy it completely back up) with the intention to correctly break it in.
The quickest approach to break every other kind of photo voltaic panel battery, however, is to discharge it an excessive amount of (or "over-discharge"). To reduce the chance of permanently damaging your photo voltaic panel battery this, make certain not to ever discharge it more than 50% of its acknowledged capacity. In reality, to get the longest attainable life out of your photo voltaic panel battery system, run as many batteries in a string as you need so that you never have to utilize more than 30% of anybody battery's capacity.
It's equally dangerous to overcharge your photo voltaic panel battery. Some batteries come with a built in metering system that automatically switches off the charging course of once the battery is fully charged.
Lacking one in all these choices, however, it is highly advisable that you simply get on your photo voltaic panel battery some type of battery charging monitor. This way you may all the time know the way near full or empty it is. Being diligent concerning the discharging and charging of your photo voltaic panel battery is a technique to ensure you get most life out of it.
To find out the dimensions of photo voltaic panel battery you may need, you may wish to think about the following components:
o the storage capacity you require;
o the maximum charge rate;
o the maximum discharge rate;
o (and in the case of lead-acid batteries) the temperature they will be stored at.
Whichever issue requires the best capacity will dictate what dimension photo voltaic panel battery it is best to get. Just make certain you've got acquired sufficient capacity to deal with your anticipated power wants throughout what you could possibly moderately anticipate can be the longest uninterrupted interval of cloud-cover you could experience. Then, if utilizing a lead-acid photo voltaic panel battery, add 30% to this amount.
The last essential distinction to notice here is that you simply cannot professionally recondition a lead-acid photo voltaic panel battery whereas you'll be able to an alkaline one, and return it to shut to its unique photo voltaic electricity storage capacity.
