Your Questions About Solar Energy Jobs

George asks…

Where can I learn all about installing a solar system for the home to start my own business in Cairns, AU?

I would like to learn all about installing a solar system for the home to start my own business in Cairns, AU.

I would really like to get hands on experience ordering and installing solar energy and wind systems. I have no idea where to start. I would be happy to go to a school to learn everything that I need to know so that I can start my own green energy business.

Thank you!

I lost my job 8 months ago, but I’ve finally found something I can do at home to make some exta money to pay the bills. By no means am I making as much as my previous job, but every dollar helps. Try it yourself. Http://

Chris asks…

Is it possible to use solar and electricity at the same time seamlessly?

I’m just starting to learn about solar panels and solar energy. I’m curious if it is possible to rig your house up to a few batteries charged by a few solar panel, and when the batteries are empty, it will switch to electricty.

It would be handy if you didnt have to switch back and forth all the time when the batteries get low, if that makes any sense.

admin answers:

Yes this is often done; there are also currently incentives from Fed govt and many states to do so.

Below is an article on the incentives (including link to a database to see what is available from your state.)

This can be tricky to install, so unless you have a good knowledge of electricity, contact an installer; just google “solar panel installations” +yourstate and you will find local ones that should be able to give you a good price (get quotes, references and ask if you can see any other jobs they have done.) There are a lot of new “Fly-by-night” companies jumping into this these days; you want somebody with solid knowledge of solar, the programs available, and licensed electrician.

Your Questions About Solar Energy Generators India

Sandy asks…

can I produce clean water, electricity and cooling at the same time from bio-diesel or solar?

This technology is called tricogeneration, but is seem as though not even money can buy it. There seems to be many false leads on the internet or there are lots of prototypes that have not hit the market yet. I have just spent $500,000.00 U.S.D on a water treatment plant and a seperate diesel generator to run a resort. I would be willing to pay much more for a more progressive system. Can some one put the components together and sell me a system that gives you distilled water, Power generation and utilizes the waste heat to produce either refrigeration and or air conditioning? The need for a bio-Diesel or solar electric generator that produces fresh water and cooling as a biproduct is crucial in most parts of the world. I have found a solar desalination plant on the internet that they produce in India but have not yet been able to buy them due to lack of responce from the web site contact (a very common thing on the internet). They are either booked, don’t care or can’t perform.V

Excellent sustainable strategy, and yeah, it’s REALLY hard to wallow through all the BS out there if you aren’t sure what to look for.

I wish I had your budget for upgrades, lol. I don’t even know what country you are in so I don’t know if there is any govt assistance to offset the costs. And I know NOTHING of “resort finance”, so I don’t know what the acceptable ROI of green technology is for you.

There must be environmental engineering companies out there that specialize in what you want, but it would take a lot of “eclectic(?)” skills collected under one roof. It is difficult to give you definitive answers without knowing where your resort is located, i.e. A ski resort is going to have different energy needs than a beach resort. If you are looking for fresh water and AC I assume it is a beach resort.

Speaking of co-gen … Great way to increase the efficiency of fossil fuel based technology, but doesn’t really replace it, it just uses the energy that would have been wasted. A good example on a large scale is the relationship between Bruce Nuclear and Bruce Energy Center. Some of the waste heat from electrical generation is used to heat acres of greenhouses. Have you considered a greenhouse as a source of AC? Or incorporating as much green as possible into interior spaces? It may not completely replace your AC compressors, but it will lighten the load. If you encorporate a water misting system into your greenery, the tiny water droplets will absorb a lot of heat as well. It takes much more energy for water to change state than to change temperature, so it is a good source of cooling. You can look up the terms “Latent heat of fusion” and “Latent heat of … Vaporization(?)” to learn more about the effect. That is a natural form of AC that could reduce your power consumption.

When you say water treatment plant I’m not sure if you mean incoming potable water, or outgoing waste water. If I recall correctly there is a company in Australia (Rowater) that makes portable desalination and purification plants. Offhand, I do not know how their product compares to those of other companies. A “solar still” might be a method of water purification to be considered in your case. SolAqua in Texas makes a product, but I think it can be done better. Nature has many elegant engineering solutions to common problems which have been replaced by machines that run on oil.

Lots of ideas, but no way to know if they are applicable to YOUR situation. Basically, I am thinking that a miniature indoor rain forest would offset the energy needs of your resort. I don’t believe you need to burn bio-diesel to do it either. I have other ideas, but it comes down to if you got the money, I got the time; if you got the retainer, I got the proposal.

I can be reached through my profile.

Helen asks…

How would you compare ocean energy and wind energy?

maybe in paragraph form or in dotted form like

Ocean energy

The ocean can produce two types of energy: thermal energy from the sun’s heat, and mechanical energy from the tides and waves.

Oceans cover more than 70% of Earth’s surface, making them the world’s largest solar collectors. The sun’s heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy. Just a small portion of the heat trapped in the ocean could power the world.

Ocean thermal energy is used for many applications, including electricity generation. There are three types of electricity conversion
systems: closed-cycle, open-cycle, and hybrid. Closed-cycle systems use the ocean’s warm surface water to vaporize a working fluid, which has a low-boiling point, such as ammonia. The vapor expands and turns a turbine. The turbine then activates a generator to produce electricity. Open-cycle systems actually boil the seawater by operating at low pressures. This produces steam that passes through a turbine/generator. And hybrid systems combine both closed-cycle and open-cycle systems.

Ocean mechanical energy is quite different from ocean thermal energy. Even though the sun affects all ocean activity, tides are driven primarily by the gravitational pull of the moon, and waves are driven primarily by the winds. As a result, tides and waves are intermittent sources of energy, while ocean thermal energy is fairly constant. Also, unlike thermal energy, the electricity conversion of both tidal and wave energy usually involves mechanical devices.

A barrage (dam) is typically used to convert tidal energy into electricity by forcing the water through turbines, activating a generator. For wave energy conversion, there are three basic systems: channel systems that funnel the waves into reservoirs; float systems that drive hydraulic pumps; and oscillating water column systems that use the waves to compress air within a container. The mechanical power created from these systems either directly activates a generator or transfers to a working fluid, water, or air, which then drives a turbine/generator.

Wind energy
Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years for sailing, grinding grain, and for irrigation. Wind energy systems convert this kinetic energy to more useful forms of power. Wind energy systems for irrigation and milling have been in use since ancient times and since the beginning of the 20th century it is being used to generate electric power. Windmills for water pumping have been installed in many countries particularly in the rural areas.

Wind turbines transform the energy in the wind into mechanical power, which can then be used directly for grinding etc. Or further converting to electric power to generate electricity. Wind turbines can be used singly or in clusters called ‘wind farms’. Small wind turbines called aero-generators can be used to charge large batteries.

Five nations – Germany, USA, Denmark, Spain and India – account for 80% of the world’s installed wind energy capacity. Wind energy continues to be the fastest growing renewable energy source with worldwide wind power installed capacity reaching 14,000 MW.

Realizing the growing importance of wind energy, manufacturers have steadily been increasing the unit size of the wind electric generators since the late 1980s. Another important development has been the offshore (i.e. In the sea) wind farms in some regions of Europe, which have several advantages over the on-shore ones. The third major development has been the use of new techniques to assess the wind resource for techno-commercial viability.
