Hi guys,
Forgive me if I am in the wrong place…I am so overwhelmed from endlessly searching the web on issues out of my depth. Currently I have parts to embark on a fully automated solar powered drip system. Not having time during the day (hence the automated watering system) I also need a light source to work at night when I finish my day job (veggie patch takes time to grow food successfully)
Anyways…I’ve decided to split my 2X10Watt solar panels; as the pump I am using only uses 1.9 amp/h and I’ve matched my dripper output to ensure that I only run the pump for no more than 3amps worth to which one of the 10watt panels, can feed that back into the battery on a 5 hour period with no worries here in Australia... (Water pressure tested and all that + running that 3 amp drain on an 18amp/h battery)……………SO I figure I can spare the other 10 Watt panel on a 2W LED spot light for about a 13 hour period for a light sensor to which I have no idea how to hook up. I do know that by judging by my pissy little solar lights that the sensors can cut in up to 13 hours depending on season.
SO…2Watt divided by 12Volt or 2/12 = 167 aprox gives me about 167ma/h……..HEY…I’m fairly tipsy/pissed about now, so please by all means cut in and tell me where I’m going wrong…I’m only just getting to my questions for you guys…
IF I did want to run a light on a sensor switch, allowing for a 13 hour period in the colder months…on a 12V system from a 10 Watt solar panel and 7.2am/h battery…can use one of those little button sized light sensors, or so I have to run it in series/parallel or of some kind of voltage regulator which basically I have no idea of how to incorporate into the scheme of things.
I’ve been searching for a 12V timer switch, much like a tap timer, but something I can program on a 12V circuit + a 7.2amp battery……………that way I could have a higher powered spot light running for 6.5hours instead of 13hours.
Anyways…all is not lost………if worst comes to worst, I’ll just use a manual switch. Just thought It would be good to run a spot light of my 10 Watt panel with the 7.2amp battery to show up my little solar/marker-décor lights J
HELL…What was I asking????...............Oh yea……….what kind of light sensor do I need for my proposed solar and battery set-up and how do solder it in place or where inline???
Thx guys
Dave
