Go green – go for Solar panels for generating electricity

Published / by admin

What are solar panels?

These panels are so designed that they are capable of absorbing all the rays that fall on them and the absorbed rays can be used as a source of energy for heating up the appliances or for generating of electricity for running various electrical and electronic appliances.

The technology that is used:

The panels use photon or the light energy to generate electricity through the photovoltaic effect. The materials used in the manufacturing of these panels are thin wafer like sheets f silicon or very minute sheets of cadmium telluride. The materials that are used are the ones that can aid in the maximum absorption of photons.

Best charging station:

This is one of the best ways to generate electricity in times such as

1. Emergency relief has to be provided;

2. Relief measures in places where there is a disaster due to Act of God;

3. When you want to generate electricity that is portable even under water;

4. Places where there is a provision for outdoor dining like a OTS cafeteria;

5. When there is a need for electricity lamps while camp firing;

6. At the venues of open to sky events like art festivals or Music events near the shore, etc;

There are at least hundreds of other uses for solar power stations. You have to just creatively think and conjure up the various applications for it. For example a solar charging station with a attached dining table can keep the food kept in the serving vessels longer and till every member has finished his supper. This will definitely bring down the charges on electricity especially in homes where members of the family eat separately and every time they heat the remaining food in an induction stove or a microwave

Have you heard about RV solar panel kits?

Most people opt for these kits for two fold reasons.

a. To charge their home battery slowly;

b. To create a primary source of electrical power.

Have you wondered why your vehicle engine takes a little time to start when you leave it idle for a long time?

This is because if the battery is not used for too long, the battery dies quickly. Similarly, if the solar panel is kept unused for a longer period of time, the battery has a tendency to die down and be a pain in the neck to be able to recharge it to make it efficient enough like before.

Installing a RV kit is simple. A small solar panel just the size of a dinner plate connected with wire and battery clips can create the most easy and the cheapest solar panel kit.

Goal Zero solar generator:

Have you been struck in a power outage and inspite wanted to throw that noisy fuel power generator out of the window?

Say hello to Goal Zero! The company gives you power generation solutions which are absolutely efficient and make the lowest noise ever. You will even wonder if they are working!

They are like mini power systems in themselves. They silently collect the power from the sun and give you the benefit of a clean, green and noise free energy when there is a power failure.

How efficient is a solar panel 200w?

This panel is capable of a 12V nominal voltage output. And the cell efficiency is awesomely good at 19% approximately. The material used for the body of the panel is mono crystalline silicone. The panels have MC4 connection and are very easy to install.

They have an Aluminum frame with tempered glass which is weather proofed for durability and long life. It is priced correctly and it is a small price to pay when your intention is to go green!

3D Printing – Yesterday, Today And Tomorrow

Published / by admin

Past – History

In the yester years there was nothing called a 3D printing and it was all about the use of subtractive methods wherein exact shapes for a file were given with high precision through various other processes. The introduction of this method started in the later stages and the earliest applications were in the tool rooms of the manufacturing units. Before the introduction of this method, a digital prototype was created using other methods that were time taking and a little expensive. But with technological advancements and developments, 3D printing was introduced which drastically reduced the printing and object creating time and was comparatively cheaper too. Now this type of printing has a place and use in almost all sects of life. For example, check this website if we take the manufacturing sector, the use of 3D printing methods have reduced the number of faulty and failure parts to a great extent by producing the exact printed objects with precision.

Patients are now given better care and surgical assistance via 3D printed implants and prosthetics.

* Bio-printing – this printing technology is widely finding ways in the tissue engineering industry wherein body parts are built using inkjet techniques. Various layers of a particular organ are built in slices to give it a 3D shape and form.

* Automobile industry – though these were one of the first few to use this technology, it is only in the recent years that their use has become extensive. Now 3D printing is used for design verification, finish checks, functioning of parts that are used in the test engines etc…
