Alternative Energy That Shouldn’t Be Alternative Solar Energy How Do Solar Panels Work?

September 3rd, 2009 Walter Hull 1 comment

Solar energy is an excellent source that has the potential to greatly reduce environmental pollution. Unfortunately, it’s recognized as an “alternative energy” since it isn’t an energy source used by a majority of the population. One of the main reasons is that it’s still quite costly to manufacture. Right now, calculators and decorative outdoor lights are a couple of the most popular solar powered gadgets. The question remains, how do solar panels work? How does setting up a small panel, directed towards the sun, turn the sunlight into the electricity that keeps those pretty, bluish bright lights lighting up the walkway all night long?

Solar panels are made from special materials that absorb the sun’s rays and turn them into electricity that can power all sorts of electronic devices. Devices that we use electricity for everyday without thinking twice about could be powered by solar panels.

A budding technology used today for solar panels is photovoltaic (PV) electricity. It involves the use of specific materials that convert solar energy into electricity. The electricity can be used right away or it can be stored using DC batteries. Either way, we’ve got power!

These materials have been recently developed and they release electrons when prompted by sunlight. Another name for a photovoltaic panel is a “direct energy conversion device”. All of these effects take place on an atomic level without any moving parts.

Historically, only space age technology used photovoltaic panels. Space stations and satellites used them because they were a reliable source for continuous solar energy conversion. The extra bonus that using them in outer space has is that the sun’s radiation is at least 50% stronger than it is here on Earth.

People who live more than a mile from an electrical grid are better candidates for solar power use especially those in residential homes. It’s significantly more expensive to install power transmission cables than it is to install a solar panel kit. If you fit this criterion then solar energy to power your home is a smart way to go.

Still, how do solar panels work? Understanding solar energy can help answer this question. Solar energy’s made up of two kinds of radiation, and the most desirable for solar panels is called “beam radiation”. This is what we feel when soaking up sun rays on the beach in June, when there’s not a cloud in the sky. Clear days are the best for collecting beam radiation, but the solar panel needs to be placed strategically to gather the most direct sun rays possible if you want to get the most from your solar panel.

The other kind of radiation from the sun is called “diffuse radiation”. This shouldn’t be relied on for the sole energy to be absorbed by your solar panels. This is what we feel on an overcast, cloudy day or if chilling out under a shady tree. To rely on this type of energy from the sun as your main source of sunlight is far from practical.

So, with this being understood, a bright and sunny location is key for solar panels to work effectively. Beam radiation is very important and most of Western America fits this bill. However, northern climates and coastal states pose a bit of a challenge since typical weather there consists of a lot of clouds and rainy days. Those regions aren’t prime candidates for 100% solar reliance.

Solar panels can be set-up to meet your specific needs. 12 volt, 24 volt, and 48 volt DC systems are the most common. The life expectancy of 12 volt solar panels is well over 20 years and they fall in the range of 12-14% efficiency.

Solar power is still “alternative energy”, and part of that is due to its high cost to produce. They’re so expensive because they are made of supremely pure silicon semi-conductor materials. New materials are being explored and they’re geared toward lowering production costs, making solar energy more readily available to the general public. Cadmium Telluride based solar panels are one of the new technologies being explored, and if these are successful materials then solar panels should become more affordable for the average citizen. This is great news for the environment as more and more people convert to solar energy, the atmosphere can begin to heal.

You’ll want to assess your weather patterns as well as your local utility rates before making a final decision as to whether or not to install a solar panel system at your residence, but the benefits to the environment truly outweigh the monetary aspect. The decision is much simpler if you intend to use solar merely as a backup plan. Energy independence is a common goal for all. It helps the environment in so many ways that simply can’t be ignored.

Self Storage – Important Questions To Ask A Company Before You Rent Space From Them

September 3rd, 2009 Randy Bell No comments

The advantages of self-storage are numerous. Any professional warehouse or storage company will offer you this highly useful service and it is becoming highly sought after by the day. It is very important when you have some renovation or interior designing to do or if you have too much stuff being used rarely but it is cluttering your living space. The reasons could be many but before deciding upon a self storage service there are a lot of questions that you ought to ask the service provider.

The foremost concern of anyone considering self storage should be the security arrangements. You cannot leave your valuable items with a self-storage service provider without knowing if it has all the latest security systems installed in its facility.

You must also look at the market reputation of the company and find out how it has fared in its business so far. The security system of any good self storage company should have fire alarms, CCTV cameras, police supervised alarms and electronically monitored door access system.

The second most important question to ask a self storage firm is if they have climate controlled facilities or not. Adverse climatic conditions can tarnish the exteriors of items of aesthetic value like expensive paintings and even good quality wooden furniture. Too much humidity in the air or extreme temperature may harm such delicate items.

Lastly, the services must be such that they are worth the money, and the price is flexible and proportionate with the service. The cost will change depending upon the amount of space required by you for storage, the period for which you require it, and whether the company offers climate control or not. Check what the normal price in the market is, and as the industry is quite cut-throat you can always ask for concessions, particularly if you are storing several items.
