Air conditioner 25 volt 5 amps: how many solar panels and batteries to run 24/7?
- OK, in addition to the solar panels, you wil need an inverter (DC to AC; 2V t0 20V) capable of delivering 20A continuously and as much as 40A for the compressor starting surge, and a fairly large battery bank capable of delivering something over 2000 watts continuously (losses in the charging and conversion process) as well as the surge. So, if your actual demand is now calculated around 2000 watt/hour, and you need to both run the unit and charge batteries during the daylight hours - and considering that the ideal charging rate for a lead-acid battery is on the order of 0% of its capacity, you will need a huge reserve on the battery section and a huge excess on the solar section to make up for the 5 hours maximum input. So, the average high-quality deep-discharge battery will do about 400Ah @ 2.6V. Which comes to 5040 watts for one hour. For round figures, it will give you 2000 watts for 2.5 hours. You will need a minimum of eight of them just to make your system run for the 9 hours you are anticipating. Given that you do not want to run the batteries to zero each night, a 50% reserve would be a wise investment - comes to now twelve (2) batteries. Now, you will have to make 2000 watts (to run the unit) and also produce and another 8600 (per hour for five hours) watts to charge the batteries for the next night. Again, for round figures, you will need 0,000 watts of solar power, or seventy (70) panels. At ~0 watts/s.f. (00 watts/meter), that comes to about 000 square feet or 00 square meters. Modern non-crystaline panels may reduce this by 20%, or so but no more than that. You will be charging the batteries at roughly 20% of their discharge capacity - which will pretty much cut their service live in half, or so. As the average deep-discharge battery has about an 8-year life span under ideal conditions (and your situation will be far from ideal) you may expect to replace them every four years or so with good care. Much less with no care.s
Battery for 2V .5W solar panel?
- batteries are rated via the CCA, chilly cranking Amps the better the CCa the longer it is going to very last, don,t imagine you want a cost Controller as your continuously drawing juice from it, the picture voltaic panel will keep the bat at its top , then even as the daylight is down , the pump will draw off the bat,s
how much do solar panel batteries cost?
- Solar Panel Batteries Costs
i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
- Well you are stating the solar panel powers but no mention of their voltage??. Yes, they should do the job. I suspect the lack of blocking diodes may be your problem, assuming you have done the homework. You have 6 battery cells at 2 volts each, that is ...err..2 volts, assuming you have them connected in series. Count the number of cells on the solar panels and maybe we have a starting point. One solar cell is 0.6 v, in this case you would need a minimum of around 30 cells (physically it will probably be 32 to make it 'square'), you need a fair bit of over- sizing in that direction. Solar panels are resistive when not illuminated so must have a blocking diode included to prevent the batteries from discharging into the solar panels at night. Check that each array has a blocking diode included, if not add them. Solar power is pretty useless unless you have loads of sunshine. You seem to have gone through a bit of trouble and expense on this one, so give me some basic facts and I will help you through it. Update 7 Dec If the batteries take 20 hours to fully charge and there are 0 hours of sun each day then the batteries will be fully charged in 2 days. The question was, can the battery be charged, answer is yes, it can. There is no mention of load. If the batteries are not charging there is something wrong.s

How do you connect a solar panel to a motor from an RC car?
- can increase your voltage from a single solar panel. In combination with a large capacitor, you could deliver short bursts of power to the motor which would allow intermittent operation.s
Sizing solar PV panels?
- 75 amps @ 240 volts equals 8 kW not 9.4 kW, so first you have to make up your mind how much you want. Then you have to decide what size of solar panel you want. If it helps, the 6 units on our roof, each approximately m square, are rated for 4 kW in bright sunshine.s
Solar Panels for home use?
- For a starter you would look at how many watts you use. And how deep in you want to go. 80 watts at 2volts dc is nice.. But getting it to 20 ac. You will need a good inverter, battery's. There is things that you can replace in your house that will run on 2 volts. Lights fans. But to answer your question you would first have to look at what you use or and what you want to change over. I have got 900 watts of panels and 2700 Amp hours of battery's on one system. That will run all my lights computers and TVs Also on this I have converted a ups for the 20 VAC. I have been working on this for 0 plus years with no plans to finish. ( there is no end for what you can do with the power of the sun)s
