How Big Solar Panel To Charge Electric Fence

Solar panel for electric fence both 4w or 10w sound a little small for winter use but to be correct we need more information.

How big solar panel to charge electric fence. A deep cycle leisure battery is the preferred power source and 70 ampere hour ah 80ah or 110ah units are the best choices for larger fencers. The bigger the amp hour the longer the run time. Not only is a solar electric fence going to cost you a fraction of what you d pay to have a normal powered electric fence up but it s also easy to set up because there isn t much wiring involved. Moreover the parmak df sp li has 3 years of warranty covered by the brand and is a good solar electric fence for horses cattle pigs and dogs.

3 joule energizer 30 watt solar panel. So if you have a solar panel that with a 10 watts power rating and it is exposed to sunlight for at least 6 hours. It has enough energy as to cover up to 25 miles of fence. With a 4v battery the charger has an output of 0 04 joules and can power a 2 miles long fence.

As a general rule you will need 10 watts of power for each output joule of your fence energizer. Battery voltage x energizer amps watts. Use the calculations below to determine wattage needed for your energizer and location. If one low end solar panel can produce approximately 1 kwh a day of ac electricity that means you would need an astounding 75 solar panels to produce enough electricity to fuel your tesla model s to 100 capacity from 0 each day.

Luckily the average driver travels 37 miles per day which translates to about 12 kwh of electricity. Calculate the ah per day needed determine wattage of the unit. This means that on that scenario the solar panel delivered 60 watts of power to charge the battery. In vehicle use the cycle rate is rarely 10.

Lead acid batteries should not be discharged more than 40 dod depth of discharge absolute max. This electric fence charger uses a small solar panel that constantly powers a 6 volt battery with over 42 more solar battery charging. You can get the amount of energy it will provide the battery by multiplying 10 watts by 6 hours which will give you 60 wh.
