As most of us know the sun does produce and disperses a huge amount of heat on the surface of the earth. A lot of it goes to waste when not used efficiently to our advantage. Solar power can be strong enough to power machinery and it may comes as a surprise to you but the space shuttle uses solar panels faced toward the sun in order to be able to power the shuttle efficiently.
Ok but what about when it snows and rains , when the sky is cloudy and we don’t see a trace of the sun for days. Well rest assured that with what scientist know about the sun and all resources available to them, keeping stored solar energy is a walk in the park. It is possible to produce enough heat in your solar source to create enough energy to last until the sun shows up again. Solar power is the way to the future, we must educate ourselves and prepare and we need to be ready for it. Right now solar power is primarily used by those who are more aware and worried about our earth’s atmosphere when it is a concern that we should all be worried about.
Never the less solar power is being used around the globe. It is cost effective to have a home solar power system put in place. You can choose to have a company put everything in place for you while still keeping the old conventional ways to heat your home. You can use solar energy to power your appliances only or heater only. You could also do your own research as far as material needed to implement a solar power system. There are great books , videos , DVD, teaching you how to build your own solar power system.
No matter how you look at it the advantages versus the disavantages wins hands down, solar power energy is here to stay and will become very popular in household around the world, we are living in desperate times and finding ways to cut expenses to keep a bit of what we earn in our pockets is the way to go. The price it may cost you to have a solar system put in place or to build one yourself will pay for itself in a very short time.

Sounds like you did a great job on that!
It is addictive! I keep trying to add stuff on mine. I always seem to be looking for a bigger inverter. I think it wouldn’t be hard to get off the grid in a cabin in a remote area with this system.

Until compact onsite electrical storage becomes practical, it's better to have centralized solar power stations feeding power to the electrical grid, because 1) the wiring to the lamps are already in place and/or are necessary anyway for times of no sun, and 2) greater efficiencies and easier maintenance is possible at large solar power installations than with thousands of small solar collectors. However, independent "off the grid" solar powered devices is the trend. For example, through fuel cell technology, compact solar energy storage may become possible and practical, in which case high efficiency street lamps may go off the grid, thereby reducing wiring needs.
I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills.

you just touch those batterys?

Many universities offer solar engineering classes for mechanical engineers. The design of hot water and wind power systems deal with the sciences that they have studied.
Photovoltaic systems lean more towards the electrical engineering side of engineering.

Great videos, I just setup my solar system from Harbor Freight… I currently have the 45 watt panels going to the stock charge controller, then to a 12v deep cycle battery, then to a 750 watt inverter, and currently have to light fixtures running in my house with 15 watt compact fluorescents… It has yet to drop below 12 volts… I plan on adding more to it, but I can see how this gets very addictive!

I would like to say yes but at this point I would have to say no. I worked at an ethanol pilot plant and anyone in the industry can tell you to break down starch in the corn you need what they call a jet cooker. This uses high pressure steam at appx 400-600F. There is no way in hell solar panels could heat water to this temperature effeciently and consistently. Plus a lot of ethanol plants run 24 hours a day and that right there pretty much shoots that plan in the ass. A good thought though. Ethanol will become more effecient once the enzyme industry catches up and can CHEAPLY use switchgrass as a fuel source.

Begin with the Wikipedia website.
Then look for specifics:
The energy from the Sun gives us light and heat.
The more energetic light photons can be used to knock off electrons from some atoms; the electrons can then flow through wires for electricity (photovolatic cells).
The heat from the sun evaporates water from oceans, forms clouds, rain on mountain sides: brooks, creeks, rivers… The solar energy is "stored" in the water currents as water flows back to the ocean. We intercept it to make turbines run (hydro-electricity).
Plants absorb the energy of Sunlight (chlorophyl). In trees, this becomes fibrous materials which, when buried for thousands of years, become coal. When we burn coal, we "release" the stored solar energy.
Animals eat plants (which, themselves, represent stored solar energy) and, when they are buried for thousands of year, turn to petroleum.

The .06 amps you are measuring is the charge current being delivered by the panel. At that rate it would take 50 hours to charge to 180 amp hours ( 180/.06/60 ). The 800 amps is the max instant current it can deliver.
June 27th, 2009 at 7:01 pm
this is not a slam on you. your system is nice it dose what it suppose to do. SAVE YOU MONEY! now and 20 years to come by supplying electrons to light your way at night and entertain your self. good job
but think about how we are being treated by the government

awsome

Your solar appliance is not producing energy. You can calculate the amount of energy you need to add to a liter of water to raise it one degree C. But a solar oven is not linear. That one degree of temperature rise is much easier to accomplish at 25C than at 80C. To do a project on energy, you need to learn at least the basics of energy.

There are various ways to convert the energy of the sun but I will address only solar cells.
Good things:
–No CO2 emissions or other chemicals
–Renewable
–Once the installation is built, it is "free"
–It generates electricity which is a flexible form of energy but …
Bad things:
– The installation must be in a sunny place
– No energy at night
– Under the solar panels, nothing grows and the space cannot be used for something else.
– Difficult to store the energy in large quantities
(example you store In July, August and you use the energy in December)
Future developments and research:
– very efficient solar panels ( currently at beat 20%)
see:
http://en.wikipedia.org/wiki/Solar_cell#...
– very efficient batteries

Hi there,
Engineering wouldn't be a bad field for something like alternative energy. I know that's kind of general, but maybe there is something else specifically within engineering, that may cater to solar energy, wind energy, wave energy, etc..
I guess it really depends in the school you are in, and what kind of variety with the majors that they offer.
June 28th, 2009 at 3:45 pm
looks like 3rd world to me. think about it!!!!!
June 28th, 2009 at 6:43 pm
Okay, I don't think anyone's taken this seriously yet, so…
How about, hydro-electric, geothermal steam, wind turbines, augmentative passive solar, such as water heating and daylighting (somwhat different then solar lighting, or skylighting, although skylights count.) Also let's not forget rain harvesting, and gray-water usage.these save water, and energy from a treatment, billing, delivery standpoint.
Now that I asnwered the name other part: challenges, what happens when there is no sun/wind/water-flowing, if you have all of these, it won't happen that often, but when it does, are batteries a practical solution? Won't they eventually wind up in land-fill off-gasing? If you only use one or two of the 3 majors, what about when any of those aren't available? Availability is still a big concern, hopefully that will be the next stock-market bubble and drive a massive influx of green-products.
The common challenges with non-renewables, rather than starting from an environmental standpoint, how about we start with what they're called. NON-RENEWABLE, eventually we will run out. It's theorized that we've found all oil on earth, and will start a downward turn on production by somtime in 2008 or 2009. Aside from that, there's the obvious global warming issues.
O hope this helps some.
