solar question

Do solar panels have to be in direct sunlight? I'm looking to make a "Sun Jar" and was wondering if it would work on my balcony. The only thing is our balcony doesn't get direct sunlight to it as it's inset into the building and covered by the above apartment's balcony.

Solar Charger?

Hello, I am looking to build a solar charger in a 4x3x1.6 inch (or smaller) box to be as portable as possible. My only problem is, I would like to mount the solar cell on the box. However, all solar cells are far too large to fit this box, I plan to use a rechargeable 9v battery for power storage. I was wondering if I can use a 6v solar cell, and still use a standard LM7805 5v Voltage Regulator to drop 6v to 5v, or if someone could find a 2.5x3.5 inch solar cell (9v) online somewhere (for cheap) that would really help (I've looked everywhere...) Thanks.

Solar cookery

Hi there. I am just new to the site, I have been wanting to practice solar cookery for a while when i stumbled upon this site. Guys I am amazed at what i have found here. I live in Noosa, Australia and its a very eco minded community. I have wanted to go and build a solar oven for a while but i live in an appartment so space is limited. we have a balcony which gets a large amount of sun in the morning till about 1pm. So i have an idea to build a water heater of sorts which i would like to be able to used to preserve food in the form of jams chutneys and any jared preserve basicly ( I'm also a chef so i have a know of alot ot things i can preserve including meats ) . I think my only issue is reaching high enough temperatures to be deemed safe ( above 78 C for long periods) .  My idea to do this is to use a larger sized container say around the size of a 5 litre bucket and set up a heat sink to help the temperature to get higher longer.  For the heat sink materials i was thinking of using aluminium cans and perhaps to line the bucket with it too ( perhaps just foil instead for ease). I would like to set up and array around the bucket to help collect as much sun as possible for as long as possible and seal the entire container to help condense the water pressure to sustain the heat.  I guess i question is will a large abound of heat sinks help to heat the water significantly. any advice would be welcome and yes i wull document this when i make it on my next days off work.

I found a smaller version with what I wanted to do at Popular Science but I want to do something on a larger scale.

Question: can I put a breaker or fuse between the 4 outlets I'm going to be plugging into on the outside and the plug being plugged into the DC to AC converter? If so how?USB ports for charging with on off switch. Question: how do I convert the 12V to 5V in an easy way? I've seen some creative ideas on here for charging VIA salvaged USB ports but I don't want to have to hook it up to my power inverter if I don't have to. Cooling/ventilation for the entire thing. Any ideas how I might cool/vent it? Currently I'm thinking of using old computer fans and put them on both sides of the toy box and have 2 blowing and 2 blowing out. Having the fans run off of the solar panel during the day and either have a switch to change it to battery at night (if it's too warm in the house) or maybe photo sense it? Temp sensor to turn it on and off? Or a switch to turn it off completely. I'm just looking for idea's to keep the battery (and to expand to be more than one battery) cool/ventilated. If you have examples or detailed description on how to do it that'd be great. I'm not one to steal ideas so I'll credit the idea's I'm given if I use them =)I'm going to see how much I can run off of this and how long. Hopefully save some big time energy also!Thanks all!

Solar Concentration?

I wonder if anyone has tried this, using either a solar cell, or joule thief powered LED in something like a torch head fitment  with a solar cell capping the end of the torch head such that the maximum amount of vsible light is falling on the solar collector and none is going any where else. Although direct sunlight may be ok to power a PV, because of local weather it could still be described as diffuse and tricky to get a constant intensity of light where it is needed. If it were possible get a gain in efficiency this way it also could mean that you are not constrained by the amount of area you need to lay out panels to catch sunlight, the collectorsand lights could be stacked vertically in enclosed units.Apparently PV'sare most efficient in the visible light spectrum which reduces concerns of radiation (UV or IR) If efficiency and power could be increased in this way small units could be joined in series or in gradually  increasing size to power requirements.

Solar - PV versus Solar Oven with Peltier

I was browsing the site as I am often wont to do, and spent quite some time revisiting old 'ibles covering various solar projects, almost all of which are heat related. I understand from general consensus that PV (photo voltaic) solar systems are very inefficient and one of the worst ways to harvest solar energy (when considering the cost of construction and the energy transfer capacity, etc.) Almost everyone who knows what they are doing suggest that the best (and easiest) way to harvest solar energy is to collect the heat - be it to heat air or water, cook food, or other such purposes.Now, I have recently been fascinated by a discovery relatively new to me, peltier units. These devices, for those who don't know, can work in one of three ways. They can harvest and/or produce either heat, cold, or electricity.Basically, if an electric current is run through a unit, it produces heat on one side and an equal amount of 'cold' on the other. Yes I know you can't produce cold - but for the layman, that is what we call it.Or, if one side is heated while the other side is cooled, the unit produces an amount of electricity from the difference in temperatures. One example I have seen and plan to make use of is in vehicles - if you place one or more of these on your exhaust manifold, or any other location where the engine produces waste heat, and airflow can reach it to cool the other side, you generate electricity from the waste heat energy that would otherwise just be . . . well, wasted.But it occurred to me today, if you had a unit attached in the middle of a solar collector, focusing sunlight on one side of the peltier unit, and isolate the other side of the unit in some cooling medium (perhaps even just air with a heat sink of some sort - more likely a cooling liquid though), how effective would this be at harvesting solar energy (heat) into electricity?Actually, I have been using the more common name of peltier, but I believe that for this application a seebeck unit (which is nearly the same, but different) would be required. As I understand it, Peltier units are used more as coolers and are almost always constructed with Bismuth Telluride (Bi2Te3) and used around room temperature and below; while Seebeck units are good for power generators are often constructed of PbTe or, SiGe as well as Bi2Te3 and are used at much higher temperatures.From http://en.wikipedia.org/wiki/Thermoelectric_effect :The effect is that a voltage, the thermoelectric EMF, is created in the presence of a temperature difference between two different metals or semiconductors. This causes a continuous current to flow in the conductors if they form a complete loop. The voltage created is of the order of several microvolts per degree difference.((more info can be found at the referenced wiki page on formulae etc.))Just curious on if this would ever be a decent way to harvest solar energy into electricity. I have also thought up using a thermal siphon solar heating system in which the liquid flows past one or more water wheels which power a small (and obviously slow) generator - but at that point I believe it would be so inefficient and limited in use as to just have absolutely no practical application. The peltier unit (used as a seebeck unit) would probably do better, but I am not certain, which is why I post the question.

Is this solar setup flawed? Answered

I have a 12V 10W solar panel that I'd like to use to charge a smartphone and/or a battery pack (5000mAh-15000mAh). I realise it's not a large panel but smartphones aren't that greedy and my use would be moderate. I was hoping that I could just attach the panel I have to a car lighter receptacle and use a double USB plug that I already have. Is this a sensible arrangement? The advantages, to me, are that all I'd need is a $5-$10 receptacle and I'd have a very simple setup (no inverter or charge controller, well, I suppose the USB plug would be a controller, perhaps). Would this system work? Even if it did work would it be an efficient set-up? Would there be any danger of damage to smartphone or panel? Also: will I need to earth anything or are the devices I charge capable of earthing? Would I need a diode to stop charge flowing back to the panel when there was no sun? Thanks for reading, I'd really appreciate any input on these questions.

Solar Panel Construction

Hello Everyone, this is my first forum post!I had a question and couldn't think of a better place to turn to than this.Basically, I am constructing, or planning to rather, an outdoor picnic table. I want to add some gadgetry to it and make it more multifunctional. Sorry to be vague, but a lot of it is still being worked out and since I'm going to post the project on here anyway, I'd like to wait to present the entire project as a whole.My question involves the use of solar panels as a table top surface. I have a basic understanding of how to create a solar panel powered system (http://www.rain.org/~philfear/how2solar.html or https://www.instructables.com/id/Solar-Power-System/). But my question is this: does covering the solar panel with a piece of acrylic hinder its power collecting abilities? I'm thinking of covering the entire table top surface of my table with solar panels. Aside from the obvious downfalls of people using the table and blocking sun, I thought there would be enough time when its not in use to collect power. But obviously I can't have people eating right on the panels and damaging them. Any guidance would be GREAT! I just want to know if I should even entertain this design idea or separate the panels from the table altogether. Thanks!

Solar Capillary Irrigation

I was thinking: If you used a post hole digger and made 2' or 3' holes throughout the garden, then dropped an old pant leg or other scrap fabric down the hole, filled it up with soil while leaving some fabric exposed above the soil, covered the fabric with an inverted clear plastic or glass bowl, would this draw enough moisture through the fabric to irrigate the plants near the bowl? I'm thinking the sun would heat things up for condensation on the glass which would drip down the sides to the soil while capillary action would draw deep soil moisture through the fabric to the surface where garden plant root zones are. Anybody try this before?

solar install question

Ok so I see a few solar setups online. now I have been researching for a while on this and no one can give me the answers so here i go on here. So i want an UPGRADE-ABLE solar setup. right now I have 2 150ah 12v batteries. I have multiple 50 amp charge controllers. so when I buy the solar panels I can plug in and get batteries going no problem.... My issue is the mains voltage side of things. I want to have something like a fuse box, this will have my main breaker and then the independent safety switches. the issue is to do this I need to make sure all my power is on 1 line. so if I buy a few small inverters I will not be able to piggyback them as they tend to go bang. so what type of inverter can I get that will be able to go in parrallel to allow me to get more amps if needed? I am hoping there is one that is infinitely upgradeable just in case. TLDR what type of off-grid inverter allows parrallel connection to other inverters??
