Green Energy” Is the Way To Go, But How Do Solar Panels Work?

If we are serious about decreasing environmental pollution, then solar energy should be a part of the equation it isn't a part of the problem, so it must be part of the solution. It's recognized as an "alternative energy source", as it isn't widely used as a main source of power for very many people. It's expensive to produce solar panels, and in today's world, calculators and lawn decor are two of the most popular solar powered gadgets used by the mainstream. So, the burning question that could maybe help solve our planet's current dilemma is, how do solar panels work? How does a panel harness the sun's energy and turn it into electricity?

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!

Photovoltaic technology includes the use of specific materials that have been recently developed. These materials discharge electrons when persuaded and influenced by solar power. This creates a voltage potential as well as electricity flow. A photovoltaic panel is also called a 'direct energy conversion device' since all of these effects are taking place on an atomic level minus any moving parts.

It used to be that only space age technology, like satellites and space stations, used photovoltaic panels. They were reliable for their continuous solar energy conversion, and once in outer space, the sun's radiation is at least 50% stronger than it is on our planet.

A good candidate for solar energy is someone living a mile or more from an electrical grid since it's a lot more costly to install power transmission cables than it is to install a solar panel kit. If this is you, then maybe it's time to consider solar energy as your main power source.

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 are versatile in the sense that they can be set up to meet specific needs. 12 volt, 24 volt, and 48 volt DC systems are the most widely used. 12 volt solar panels can live well over 20 years and fall in the range of 12-14% efficiency.

One reason that solar power is still considered an "alternative energy source" is due to the high cost of production. The silicon semi-conductor materials are costly, but new materials are being experimented with and they're geared towards lowering the price of producing solar panels. This would make solar power more accessible to the "average Joe", and in turn helping save our atmosphere.

It's unfortunate that solar energy is still considered "alternative energy", but that's all changing. If you're considering a conversion to solar power then there are specific considerations to be made upon deciding, but it's definitely a step in the right direction for our planet. The benefits outweigh the cost as far as our environment is concerned, especially the long term effects. Energy independence is a common goal for all, and if you just want to consider solar energy as a back up plan, then the decision is practically already made for you. Why not? The environment will benefit greatly once solar panels become financially available to all.
