Solaruino, aloof a simple solar tracking activity with the arduino duemilanove

!±8± Solaruino, aloof a simple solar tracking activity with the arduino duemilanove

This is a small arduino project I made a few months ago. It´sa simple solar tracker that turns the panel to the brightest incoming light source. In this case I used a torch to activate the 4 LDRs measuring the brightness. Futhermore the LCD shows these values and additionally the servo position. In future I will try to build an effective charger to supply current to the 9V (8.4V) rechargable battery. But I think, the solar cell will not provide enough amps to make this a real self-sufficient and autonomous unit. Used components: -1 Arduino Duemilanove -2 servos -1 LCD 16*4 characters -4 LDRs -1* 10V solar cell - some wood, a perfboard etc.

What is Solar Energy?

Solar energy is a way to convert light energy into electricity by using a device or medium that harnesses solar power. There are 2 ways we can convert solar energy into electricity, we can either convert it passively or harvesting solar power without the use of any mechanical device or actively by using a mechanical device.

There are 3 types of energy that the we can get from the sun:

Solar Light Energy. Photovoltaics is a way to convert solar energy into electricity by gathering photons or the small packets of energy inside the sun's rays. We can use this kind of energy to gather the light of the sun and use it to power the appliances inside our homes.

Solar panels convert light energy to electricity by means of interconnected photovoltaic silicon(solar cells) arranged in a module or through an array.

For a solar panel to work, it is installed to where the sun has most adequate light in your area. A solar panel only generates 12 volt of DC, therefore, an inverter is needed to convert DC to AC. AC is an electric current equal to 110/100/220 volt (depends on country) and this kind of voltage is required to power up any appliances inside the home.

Advantage
- Less maintenance because it gathers electricity passively.
- Free source of fuel for energy gathering.
- Endless supply of fuel.
- Long operational life as it does not have any mechanical device that may wear and tear due to repeated operations.
- Saves electricity bill.

Disadvantage
- High initial cost. ROI will be achieved in about 1 to 5 years.
- Must be installed on places where 100% of the sun's light is achieved. A cloudy location means a decrease in power output.
- Power can only gained during the day but we can install batteries so that we can still use solar energy even when the sun is not up.

Solar Thermal Energy. Harnessing solar energy but it is converted to heat energy. Examples of which is using the sun to warm a home's indoor environment, heat water or a swimming pool.

A solar thermal system is a like a solar panel but it's goal is to gather the sun's heat. Instead of mirrors and silicon solar panels, it uses a black colored panels with a heat collector and instead of generating electricity, it is converted heat energy.

Advantage
- Unlike solar panels, it does not require adequate solar light to gather solar energy.
- It is used passively meaning less maintenance compared to mechanical type of solar power systems.
- Endless supply of energy because the sun does not decrease nor deplete it's energy rate.
- Saves fuel and/or electricity required to heat a water or keep your indoor environment warm.

Disadvantage
- Will only function during the day when the sun is rising.
- Not recommended on shady or cloudy locations.
- The initial cost is high but there are other options like recycling that can decrease the total initial cost.

Concentrated Solar Power. Concentrated Solar Power uses lenses or reflective mirrors to focus light energy into a small area to generate a very high temperature that powers boils the water and powers the steam turbine thereby generating electricity.

Concentrated solar power systems are not similar to solar panels although it appears as if though it is using a solar panel but it is not a solar panel but a reflective panel all aimed at a tower thereby generating heat high enough to make steam turbines work.

Solar cooking is an example of concentrated solar power. It uses a reflective cooker that gathers the sun's light and then aims it at a specific location to concentrate light therefore generate heat.

Concentrated Solar Power is also used to generate electricity. A dish or a parabolic trough may be used on homes but they all require a larger space and because concentrated solar power uses steam and a generator, but the downside is it might be too loud for neighbors.

Advantage
- Limitless fuel source.
- Saves on electricity bill.

Disadvantage
- Too loud and not neighbor-friendly
- Too bulky if used at home, requires larger space.
- Must be on constant sunlight to acquire 100% power.
- Has a mechanical device and uses water to generate electricity therefore requires more maintenance.
- The sun is not available at night.

Conclusion

Solar energy is free and renewable however its primary cost is high. But if you think carefully, the one time cost of solar panels for example is sufficient enough to save you at least 40% of your electricity consumption per month that will go on for years and years.

LEED, an internationally recognized green building system rates a building or a house that meets its standards for being environment friendly and conserves energy. With your green aims, plus using all the means necessary to save on electricity bills and reduce carbon dioxide emissions, it's a waste if you do not get your home or building be LEED certified. Who knows you might get a LEED Platinum rating for your efforts.

Well it has been just over a year since the solar shed first got set-up and it has progressed quite a bit so far. This is just a minor update video with a couple of new additions such as a mains power link and new external light plus some commentary of the trouble we had during December-January winter months. Forgot to mention in video, also planning to move the wattsup meter enough to fit a switch either side of it to reset the figures easily. As it is the meter has no reset button and the only way to do it is wait for dark and manually disconnect the batteries.

Solartech SPM010P-D 10-Watt 12-Volt ES Polycrystalline PV Solar Panel

Polycrystalline solar panels are made from silicon wafers cut from multi-crystal silicon (they are also known as multicrystalline panels) and are also more efficient than amorphous panels. Polycrystalline panels are excellent for all small solar applications like RV's and 4WD's. Larger polycrystalline modules are also suitable for domestic and business solar installations. Polycrystalline modules come in both 12-volt modules to cater for 12-volt power systems and 24-volt modules for larger installations. They can be linked in parallel to maintain a 12-volt/24-volt system or can be linked in series to create a higher-voltage system. These modules have proven performance at high temperatures and generally feature a robust design makes the product durable in the field and easy to install. A polycrystalline solar panel is made from a block of silicon that has multiple crystals. These panels are square in shape, and may have a surface that looks somewhat like a mosaic due to all of the different crystals that make up the panel. Other types of panels may appear smooth and even, because they are made up of only silicon crystals, whereas the Polycrystalline looks fragmented and angular. The lifespan of a polycrystalline cell is a minimum of twenty-five years and can be more than fifty, making them a worthwhile investment for long term use. 10 years limited warranty of 90-percent power output and 25 years limited warranty of 80-percent power output. Specifications - Cell: Multicrystalline silicon solar cell (78mmx26mm), No. of Cells and Connections: 36 (4 by 9), Operating Temperature: -40C to +85C, Type of Output, Terminal: Junction box, Power at STC (Pm): 10W.

Making a solar panel at home

!±8± Making a solar panel at home

These days, building the solar system is not too difficult a task as long as you have access to some detailed instructions about the best and most comfortable, where you can always find online. With the help of necessary tools and a little 'skill on my part, you too can own your solar system!

This may sound complicated, but the truth is, in reality it is not! All you need is your basic carpentry tools. Maybe they already have at home,and if they are not readily available at all stores. You need a drill, saw, glue, a soldering iron, knife, etc.

Conditions for your project DIY solar panel

The question of importance, of course, solar cells, without which you can not just make a solar panel. You need cells to see how much power you want to buy produce. Be careful when buying solar panels and make sure they are not defective in any way.And 'better if you get your cells from cards, which will only make things easier for you.

Another important requirement is a container large enough that it can easily contain solar cells. The most preferred and suggested material to use for this container of wood, is safe and can be easily done at home, especially for the solar panel.

Inside the container, you need to build a hook for attaching the solar panels. They are easy to find direction on howdo so through different sites of DIY solar panel. Apart from that, you need to build a cover for the container and to protect the solar cells. It is recommended to create this cover of a transparent material such as Plexiglas or something similar. Then you need to puncture the container with some holes through which the wiring is in transit.

Now, here's a tip for fixing the cells within the container: Use silicon seal. But there are some things thatYou must remember that the seal on the demand for silicon. Apply a generous amount of it on the center of the cell, but never at the corners of the cell. This is because there is always a possibility of expansion in the wood, which can easily damage the solar cells.

And that's all there is to it! When you are done with the panels, try to see whether correct or not. Now why do you need a voltmeter, which is again, easy for everyoneDrugstores. All you have to do is the solar panel in an area where you can spot exposed to direct sunlight. Connect the voltmeter to the plate and wait until you see a reading of 18-20 volts. If the reading appears, you can celebrate the success of your project DIY solar panel!

Solar panels on stop signs

!±8± Solar panels on stop signs

I noticed something the other day while driving, which really surprised me. The first thing was that the stop signs had to cancel the four-way traffic lights on them that were flashing red. I thought this was a good idea, and could actually cause accidents, especially because this area was a bit 'dark night can not lampposts near the intersection.

So I went to my work, happy with the way some of my taxes were spent.

The next morning, when I droveWork, I came to the same intersection and I noticed that it is no longer flashing. That makes sense, I thought, because during the day, it's not really a problem, people can usually see signs of stopping. But there was something strange about these characters, and there is no other traffic at that time, I pulled my car up and down for a closer look.

It turns out that solar panels on the signs. I liked it! Apparently, the solar panels soak up the sun during theSave the date, and then somehow the night football and the red lights flashing. Brilliant.

It seems to me that make this one of the first steps really use a solar panel to date, rather than something that we are dreaming in the 80s.

I spoke with someone I know who works with the Department of the road in our city for this. Obviously there's a decent chunk of the city budget, which consists of solar panels devoted to other road users sign allthroughout the city. Do you want to use them on some traffic lights, intersections, school, school buses and get this! They know that the school bus you will see a flashing light on top is white? Now, some of them are powered by panels.

These steps, which will eventually be taken to respect the environment and save our energy. The great thing about taking these small steps and their use in stop signs, etc.: If we can start small, with this kind of thing that people probably do notcomplain too much, and they think that it is clean. We are able to slowly turn most of the energy we use, and create renewable energy like the sun already provides.

It can be an important step to secure our planet for future generations.
