Photovoltaic Solar Energy

Most people in this day and age would of heard or read some information on solar energy, wind turbines, saving the environment, and so on. Nevertheless you may still be unfamiliar with what photovoltaic solar energy actually is and what all the fuss is about.

Well the answer is quite simple; global awareness and human evolution have finally reached a peak and now we are looking for more resourceful ways of giving back to the environment as well as sustaining productivity in the electronic age. Since we are on the verge of a long overdue technological revolution, why not employ this enormous resolution and make the most out of what we already have, which is an endless amount of renewable energy that has been around forever, this being the sun of course.

Humanity has often made choices that sometimes do not help in the survival of our species or our planet. But then once we realize we are dealing with a real problem we have proved ourselves to be quite effective in determining a solution. A few years ago we did start to take baby steps in saving out environment
by making people more aware of recycling, carpooling and renewable energy sources. Since then we now know for certain that coal and oil will one day be depleted which has boosted the exploration into alternative sources of energy. Photovoltaic solar energy was the turning point, sending us into a journey of
positive clean productivity.

Photovoltaic’s, also referred to as PV, is the field of technology and research related to the application of solar cells for energy by converting solar energy directly into electricity. The idea of photovoltaic solar energy probably sounds a little difficult to comprehend when really it is quite understandable. Small solar cells that capture the light convert this into a direct current of electricity, which can be used to power equipment and even to recharge batteries. These cells are placed and sealed in behind a glass sheet, on a smaller scale these modules are very capable of powering an emergency telephone just as an example. Homes or businesses instead would require multiple modules joined electronically. A collection of solar cell modules represents what we know as today, as solar panels.

Accessibility to photovoltaic solar energy has accelerated. In earlier stages it was mainly used to power orbiting satellites and spacecrafts, and today it is commonly seen on your next door neighbour’s rooftops, in hospitals and businesses, even on the side of the road. Photovoltaic solar energy not only plays a great part to global cause but it has given people the opportunity to generate their own power and reduce costs of living dramatically. Before we know it anyone will have the choice to go off-grid at their own discretion.

For people of the world to really get involved in something as exciting as creating their own energy and shaping this planet for future generation’s to come is truly amazing. With everything from DIY photovoltaic solar energy systems to wind power kits already available today there is certainly something for every budget and skill level. I guess now all that is left is the question, are you ready to jump on the innovation wagon?

I have written this article in hope that it will give you a little more insight to photovoltaic solar energy, I would also suggest taking a look at another great article Solar Energy Systems and if you get that far you may be interested in DIY Solar Panels

Diy Solar Energy

Previously, solar power or solar cell panels are just available in commercial areas and hardware stores. Nowadays, more and more people are trying DIY or do it yourself kits. You will have your own personal setup in only 1 day, provided you have a simple kit to begin with. Solar power may be accomplished right in your very own home, without the assistance of a professional. Make sure you keep to the instructional guide carefully to find the best results.

Building Your own personal Solar Power Generator

You should use parts which are available on the net or your local store. You can create a tiny solar power generator having a budget of only $ 200 to $ 300. This is fantastic for power failures and life outside the power company. The setup may also effectively power the modem, television, DC appliances, computer, cameras and lights. You can use this in cabins, archaeological digs, tents and camping trips. This is actually the ideal setup for those who happen to be undeveloped regions and countries.

Initial Steps

To start with, you have to make or buy your tiny solar panel. You can get a device rated at 12 volts or higher for only $ 100 in a marine supply store or RV store. Next, buy a battery. Experts recommend that you get rechargeable batteries from available green companies. Get any size of deep cycle 12 volt lead/acid or gel battery. You’ll need the deep cycle battery for nonstop use. The type in the car can be a cranking battery, which is wonderful for starting engines. It’s also possible to want to find bargains along with other discounted prices that may cost only around $ 50 to $ 60.

Next Steps

Have a battery box in places you will position the generator in. The therapy lamp may cost around $ 10. It is great for within the exposed terminals in the event you have kids inside the house. If you want to install the system in a cabin, pump shed or boat, you are able to skip this task. Buy a 12 volt DC meter. This will cost you around $ 25. Purchase a DC input. The triple inlet model is recommended. You can buy this for only $ 10 with a car parts store. The unit will probably be great for powering DC appliances like lights, hair dryers and floor cleaners.

Should you decide to power AC appliances, you’ll need an inverter. The inverter converts the stored DC power in the battery straight into AC power for majority of household appliances. Measure the watts that you’ll want. Cheap inverters of various sizes can be bought online too. Work with a drill to add the meter and DC input to the top region of this area.

Charging

Subsequently, use insulated wire to connect the meter to the wingnut terminals on the battery. Link the negative pole initially. Only handle a single wire at a time. Link the DC inlet straight towards the battery inside a similar fashion. Link the solar panel towards the battery exactly the same way. Shut the lid employing a bungee cord to help keep everything tight. Position the solar panel in the sunshine. It may need 5 to 8 hours to charge dead batteries. It is possible to power different devices like fans, lights and radios.

Solar Thermal Energy

Solar thermal energy refers to using solar energy (the renewable energy generated from the sun) for thermal uses. This energy is completely renewable, which could solve worldwide energy problems. It is important to keep in mind that solar thermal energy generates a different kind of energy than photovoltaics. Solar thermal energy is harnessed through low, medium, and high solar collectors. Each applies the concept of thermal energy generation in various ways.

Low temperature collectors are flat plates, which are generally used for heating, cooling, ventilation, and process heating. Solar process heating is used to for hot water or space heating for large or commercial buildings. In the United States heating, ventilation, and air conditioning accounts for 25 to 50 percent of energy use. This large amount can be offset by instead using solar thermal energy. Thermal masses can be used to store energy collected from the sun during the day and is then able to release the energy during cooler periods, such as the evening. These thermal mass materials most often include stone, concrete, and water. An important aspect of using solar thermal energy is to consider the climate, daylight, and shading conditions. Without adequate sunlight, thermal energy does not work as well.

Medium temperature collectors are also flat plates, but instead are used for commercial and residential hot water heating. They are most often used for cooking. Temperatures can reach up to 350 degrees Celsius, which is more than adequate for cooking. Drying and pasteurization is also possible through the use of this form of solar collecting. The simplest form of medium solar cookers reaches temperatures between 50 and 100 degrees Celsius and is a basic box design. The thermal box material is heated from the sun throughout the day, creating the cooking temperatures.

High temperature collectors differ immensely from low and medium collectors, as they don’t use plates. Instead, high temperature collectors use mirrors and lenses to concentrate sunlight. High temperature collectors often use a heat engine for their space heating. The efficiency of the heat engine increase with the temperature of the heat source. This is called concentrated solar power. This technique helps to lower the environmental impacts of conventional power usage. It is possible to generate temperatures up to 600 degrees Celsius with this technique. For higher temperatures steam turbines and gas turbines can be used. This form of collecting is generally used for electric power production.

Thermal heating is still currently used in the Middle East. A solar thermal chimney collects energy during the day and then released it as the day cools. Updrafts through the chimney pull the air through the building, creating heat. This technology has been around since Roman times.
