How to start a solar life

To say you have a solar life you should have at least one device that works with solar energy.

The house is one of the first places people think of when they think of solar energy, but a solar house must have solar panels and this can be difficult because the cost of solar equipment for the home are still a bit expensive.

But there are other solutions which start a solar life. They are solar outdoor lamps, which are not as expensive. Having a charger for cell or solar ipod is also a good solution and you can get for under $ 100.

So if you want to switch to a solar life you have to think ahead, but taking action today. And as we saw no need to invest a lot of money, but small changes all work together to Solar Energy.

Transform the sun's energy

The solar energy can be used in two different ways. As once did Romans Greeks and all the classic peoples who worshiped you can use the heat energy that gives us, so, with solar collectors of different types, heaters and concentrators can heat water, but not at very high temperatures, they can not overcome the 4000 ° k so that solar energy will not be useful when melting metals in blast furnaces etc. .

But some things can be achieved, depending on the ingenuity of the designer and the technological possibilities: To collect the heat energy from the sun several devices are used for flat plate collectors: flat plate collectors intercept solar radiation on an absorber plate by passing the so-called carrier fluid.

(This, in liquid or gaseous state, is heated passing through the channels by heat transfer from the absorber plate).

The energy transferred by the carrier fluid, divided by the solar energy incident on the collector and expressed as a percentage, is called instantaneous collector efficiency. The flat plate collectors generally have one or more transparent plates to help minimize heat loss from the absorber plate in an effort to maximize efficiency coverts. They are capable of heating carrier fluids up to 82 ° C and get between 40 and 80% efficiency.

The flat plate collectors have been used effectively to heat water and for heating. Typical systems used for home-room fixed collectors mounted on the roof. In the northern hemisphere they are oriented towards the south and south to the northern hemisphere.

The optimum angle of inclination to mount the collectors depends on the latitude. In general, for systems used throughout the year, such as producing hot water, collectors are tilted (the horizontal plane) equal to 15 ° latitude angle latitude and 20º S and 20º latitude orient N, using so more solar energy.

In addition to the flat plate collectors, typical hot water systems and heating consist of circulation pumps, temperature sensors, automatic controllers to activate the pump and a storage device.

The fluid may be both air and liquid (water or water mixed with antifreeze), while bedrock or an insulated tank serve as storage of energy.

Concentrating solar collector energy:

For applications such as air conditioning and central generation of energy and heat to cover large industrial needs, flat plate collectors do not provide fluids with temperatures high enough to be effective. They can be used in a first stage, and then the fluid is treated with conventional heating means. Alternatively, collectors can use more complex and costly concentration.

They are devices that reflect and concentrate solar energy incident on a small receiving area. As a result of this concentration, the intensity of the solar energy increases and temperatures receptor (called “target”) can approach several hundred or even thousands of degrees Celsius.

Concentrators must move to follow the sun if they are to act effectively; the devices used for this are called heliostats, mirrors that are mechanically moving or computerized control to reflect the maximum amount of solar radiation at the target.

Solar ovens:

Ovens solar energy are an important application of high temperature concentrators. The biggest, located in Odeillo, on the French side of the Pyrenees, has 9,600 reflectors with a total area of about 1,900 m2 to produce temperatures up to 4,000 ° C.

These furnaces are ideal for research that requires high temperatures in pollutant-free environments, for example in materials-research.

Central receivers of solar energy:

Centralized electricity generation from solar energy is developing. The concept of central receiver power tower or a matrix of reflectors mounted on computer-controlled heliostats reflect and concentrate the sun’s rays on a water boiler situated on the tower. The steam generated may be used in conventional cycle power plants to generate electricity.

The houses of the future:

Often speaks of smart homes, houses built and specially designed to reduce household energy consumption by focusing especially on energy saving and heat loss. These smart homes, for example have large windows facing south to heat inside in winter and some blinds designed to generate inside a refrigerated space in summer, without spending all electric or fossil energy for heating or cooling.

Also the walls are constructed from ceramic materials that keep heat in winter and in summer expel addition to using concrete tanks or water tanks to keep the heat for the winter night.

These small changes in our lifestyle as smart homes or use double glazing, insulate the house to avoid losses etc. to avoid the risk of passing as in photography; will make in the future global energy consumption is reduced considerably and so, like a domino effect, can save nature and our quality of life much better.

Black bodies:

As described in the introduction, and in relation to the previous point, there is theoretically what are called black bodies (bodies would be able to absorb all the radiation incidiesen upon him), that if someday encontrasen would be a invaluable as devices such as flat plate collectors and solar cells would yield very close to 100% and the scientists only have to worry about how to avoid heat loss and electric resistance and the like; the energy crisis would be solved, with solar energy solution.

A Winter Checklist for Your Grow Room

A Winter Checklist for Your Grow Room

With winter weather just around the corner, it’s an excellent time to get your grow room prepared for conditions that are less than favourable. You can simply spend about five minutes using the checklist below to make sure that you’re ready for whatever Mother Nature throws your way in the midst of winter.

  • The temperature inside your grow room should be monitored day and night so that you can identify any failure in your heating system immediately. To get the results you want from your hydroponics system you will have to maintain a room temperature that is conducive to growing healthy plants. By purchasing a meter that gives you a reading for humidity and temperature you will have an accurate gauge on which to base temperature adjustments if necessary. Generally speaking you should aim for a temperature that ranges from 24⁰C to 28⁰C.
  • Can additional heat be generated if your growing room temperature drops suddenly? If you have an oil radiator or one of the convenient tubular heaters, you should be able to recover from loss of temperature rather quickly.
  • Have you sealed your grow room so that cold air and draughts won’t disrupt growing? Be sure to caulk around your windows as well as any other openings in the walls that can allow cold air to enter.
  • Check to make sure that your lights are coming on at the appropriate times. Since temperatures normally drop during the night, it’s recommended that lights be run during the night. You can use HID lamps that maintain a suitable temperature in which your plants will thrive. Once the sun rises, the amount of generated heat that your grow room needs will be reduced.
  • Try to draw some fresh air into the grow room from outside when possible. Don’t allow the cold air to come in direct contact with any of your plants, but instead use an intake fan to bring fresh air into an adjoining room and then direct it into the grow room.
  • Remember to never set your plants on the floor if they are growing in pots. The floor beneath them can be extremely cold and this will shock the plants. If you want to place any plants on the floor, use a tray under them to buffer any cold air.
  • Track the temperature of your nutrient solution. It’s important for your plant roots to receive access to a nutrient solution which will promote substantial development and rapid growth. By using a digital thermometer you can successfully maintain the proper temperature for your nutrient solution. Keep in mind that only one or two degrees can make a difference in the health and growth of your plants; a temperature that ranges from 18⁰C to 20⁰C is ideal for them to thrive. Remember that a nutrient solution that is too hot can cause root rot, and one that is too cold can stunt the growth of your plants.

External Lighting

6 Things to Consider When You Are Installing External Lighting

Installing outdoor lighting is one way to create a safer, more welcoming, and more attractive home environment. External lighting helps provide security for people in the garden and makes the property less likely to be a target for criminals. And external lighting can simply make a big decorative difference to the look of the home – perfect for entertaining. Here’s what you need to know when you are deciding on outdoor lighting.

  1. Understand What You Are Trying to Achieve

Different types of lighting will help you achieve different goals in the garden or yard. For example, when you are deciding on the type of lighting to install, consider what you are hoping to achieve and where you want the light. Think about whether you are looking to create an area outside for entertaining, or if you want to ramp up your home security. You may simply want to light a path better so that elderly relatives are safer in the evenings.

  1. Consider the Practical Matters

Before you start the lighting project, figure out the answers to key practical questions like: how are you going to power the lights? Where will the switch be located – is it in a safe and dry place? Will neighbours be adversely affected by the lighting?

  1. Choose Fixed Lighting Solutions

A permanent light fitting is often the best solution for outdoor lighting as it is sturdy, efficient, and can be wired up to the existing power supply. In this way, you can fit an outdoor security light or a set of decorative lamps around the patio, and have them wired to the electricity supply in the house and operated with the regular type of light switch. You can even install lights into decking, or around pathways. For supplies for this type of lighting project go to a specialist wholesaler or retailer like www.reconelectrical.co.uk.

  1. Consider Portable Lighting

If the situation calls for temporary or cheaper lighting solutions then you can find a range of affordable battery-powered lights for decorating the garden. These range from battery-powered lights to hang from trees, to spike lights that are driven into the ground to light a path. These lighting options are good for irregular use but are not suitable for enhancing security or lighting a patio on a regular basis.

  1. Think About Positioning

You need to consider the glare from a light and how that affects people in the garden as well as people in other next-door properties, or on the street. When you install security lights or spotlights you need to make sure that they do not create a nuisance when they come on at night. Floodlights should also be positioned high above the ground to give the best effect. It is best if you experiment with light positioning using a temporary structure before you fit them permanently.

  1. Remember Safety

Installing outdoor lighting is not a difficult task but with every electrical project you need to consider safety by using steel armoured wire which is buried deep, plus a low voltage system for the whole circuit.

What is the future of solar energy

What is the future of solar energy?

What is the future of solar energy

I will summarize in two words the future of solar energy, VERY PROMISING.

Why is it explained below.

Solar energy has been used since ancient times. In Mesopotamia, for example we know that the priests lit the ceremonial fire with curved mirrors of polished gold in 2000 BC also said that Archimedes used mirrors to sink enemy ships diverting sunlight towards them.

In more recent times by the year 1930 they became popular in Japan solar collectors to heat water, but the low cost of fossil fuels at the time relegated quickly to solar energy.

It was not until 1973 when OPEC oil prices shot and solar energy back to the world map, since that day has been steady growth.

Today in the early 21st century, the energy future is more promising than ever.

A part of that oil prices have soared in recent years, thanks to predicted it will end in the next 20 years, the population has generally realizing that unless we take action on global warming, our grandchildren they will have a promising future.

Every day more discoveries to improve both efficiency rates of solar energy are made, and while the prices of fossil fuels will not stop rising, prices of solar energy will not let down.

So if you were looking for was whether the solar energy has a promising future , the answer is a resounding YES, solar energy has a promising future, and the more people we use the know and have a brighter future and faster.

Installation Technician Solar Energy

Installation Technician Solar Energy

Installation Technician Solar Energy

Companies in the sector are not qualified personnel by increased demand has led to the reform of the Technical Building Code. The standard requires that new residential buildings have a percentage of renewable energy, which will double in the medium term the current templates of solar technicians, according to various experts consulted.

Step Belen Jimenez, partner and manager Novasol, acknowledges that installation technicians needed two more solar power, by increasing the workload, but so far have had to make do with one. “No skilled labor. Soon we’ll have to get another, but struggling to find staff.”

Salaries for technical installers of solar installers are around 1,200 euros, although the shortage of specialists may raise this amount when the need is pressing. Something that, according to Jimenez, will occur later this year, as many construction projects currently under construction are still subject to the old rules.

Technical solar energy Novasol responsible shows that there has been a sharp increase in requests from individuals, therefore the increased awareness of Malaga as the increase of information. “This year demand has grown much.

The Technical Code brings major projects for the future, when the houses are already built, but people who are not required is increasingly aware and ask individual installations. ”

In Malaga they operate a hundred medium-sized companies, with an average of six installation technicians in solar energy, and an estimated fifty other make compatible these works and plumbing work as freelancers. In all, some 1,000 professionals, according to industry sources, which can expect double that number to meet the demand of new housing blocks.

In the province, close to the first level of solar radiation, the standard requires that 70% of the hot water will have to come from renewable sources.

Avalanche of requests

Ramon Alvarez is an engineer in Malaga Immosolar delegation of a German company specializing in large installations, responsible for projects such as the provision of hot water at the Kempinski Hotel in Estepona. This expert agrees good medium-term prospects.

“The buildings are older now make projects to 28 September 2006. I believe that the new projects submitted to Industry thereafter will run to the middle of this year and early next. In 2006 there was a spate of projects to avoid the rule. ”

In his view, companies require a lot of manpower, so has generated a great demand for staff, and makes other professionals from fields such as plumbing, entering this sector. At the same time, it ensures that they are creating many specialized entities. “The solar energy works with simple, accessible to small business teams.”

This expert highlights another possibility of development, such as the self-employed. “The entities increasingly opt to have a base template and workers who have recourse to large point projects, peak demand.”

The boom in renewable energy has led many professionals back to school, looking for a field with great potential for business. Alvarez is also a professor at the Institute Autesel in the PTA, where almost a hundred technical future are formed. “There are many training requirements. A year ago only I had a six people. Now, there are six classes of 15 students. ”

The Junta de Andalucía and the Municipality of the capital, through the IMFE, and sponsor specific training courses free. Between 150 and 360 hours according to whether it is general or specific-theoretical teachings and practices enable to design and assemble hot water by solar energy. “Some courses have waiting lists Board of more than 50 people. There is a tremendous demand for training.

The idea is to train students of business first and then create your own business. “But if you opt for a private program, prices reached 2,000 euros. In return, many offer practical and even a commitment to hire. “Companies are already looking to their workers among the students.”

The head of human resources Autesel, Laura Girl, confirms the growing interest of business to integrate students into the workforce. “They ask students to do internships, but usually after the first month of the contract.”

Girl says that given the lack of work experience of new operators, the courses have become a guarantee of their professional training. “At first they are asking experienced workers, but have seen that it was impossible.”

In his view, one of the most popular outlets is part of the Malaga multinational manufacturing of solar panels, Isofoton, based in the PTA. With the growth of the sector, confident girl from May a massive demand for labor occurs, the full implementation of the regulation, and hopes that the Board extend the quotas of subsidized courses spaces.

The environment is no longer a matter of fighting for a few, and has already become a booming economic sector. In the heat of the sun many citizens are finding a new opportunity to make a living.

What is Solar Energy

What is Solar Energy?

In our solar system, the largest producer of energy that exists is the sun. The amount of solar energy reaching as radiation our planet, equivalent to about 35 million times! energy producing all the power plants in Chile.

Solar radiation, of course, provides us with light and heat energy.

It can also be transformed into electrical energy. In addition, radiation is essential for the plants (through photosynthesis) to gain energy and live. Plants are the basis of the food chain on Earth (also in the oceans, of course), providing energy to the whole animal kingdom.

Types of solar collectors

Types of solar collectors

Solar thermal collectors are devices capable of capturing solar radiation and transmit it to a fluid, for later use.

The solar collectors are divided into two groups:

Solar Collectors without concentration: And they do not exceed 70 ° C, so they are used in the applications of solar energy of low temperature heat. An application example would be the production of hot water.

Concentrating Solar Collectors: Which, using the methods of concentrating optics, are able to raise the temperature of fluid above 70 ° C. These are applied in solar thermal medium and high temperature. We can find examples of these in the thermal solar plant in Almeria (Spain), Grenoble (France) and in California.
