Solar Applications

June 21, 2011 By: Admin Category: Solar Power

Solar Energy Applications

Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.

There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.

Photovoltaics System

Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.

Solar Cell Module

Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.

Thin Film Solar Cell

Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Solar Powered Lights – What Are the Benefits?

Executive Summary about Solar Powered Lights by Steve Sight

When you hear the term Solar Powered Lights, what do you think of? Chances are you think of outdoor lights that are powered by the sun. There are solar deck lights, solar post lights, solar pool lights, and solar fairy lights to name a few.

So, let’s get into the topic of the benefits of using solar powered lighting. Below you will find a list of the benefits of Solar Powered Lights and why they are important.

Benefits of Solar Powered Lighting

• Environmentally friendly- Uses natural resources (the sun) to create power. Clean and renewable.
• Very low maintenance.
• Low Cost. Energy from the sun is free.
• Easy to install. No wiring required
• Power outage will not affect your lighting.

Why should you choose Solar Powered Lights? Imagine if you did not have to pay such a high electric bill. With the use of Solar Powered Lights, it would be less.

Now think for a moment, if you were able to convert every electrically run item in your home to solar powered, how much money you could save. When dealing with Solar Powered Lights, the cost of the power is one very important incentive. However, money able to save is only one of the benefits.

Solar Powered Lights are environmentally friendly in comparison to the other more traditional sources of power. They do not pollute like coal, oil, or even nuclear power.

In conclusion, the use of Solar Powered Lights has several different benefits to one’s pocket book as well to the world around us.

Solar Powered Lights – Environmentally Friendly Illumination
Executive Summary about Solar Powered Lights by Armand Hadife

Solar powered lighting fixtures are useful in areas where there are no power supplies available and accented lighting is required.

Solar powered lights save the environment by not using any fossil fuels or releasing any of the pollutants that usual AC powered light sources emit.

The presence of other brighter lights around the solar lamps will also inhibit the lights from illuminating because the solar cells will detect this as day light energy.

Overall, solar powered lights are a great alternative to traditional outdoor lighting, especially if you want to save money on your energy bill.

Nanosolar Powersheet

Executive Summary about Nanosolar by nanosolar.com -MICHAEL MOYER

Imagine a solar panel without the panel. Just a coating, thin as a layer of paint, that takes light and converts it to electricity. From there, you can picture roof shingles with solar cells built inside and window coatings that seem to suck power from the air.

Cost has always been one of solar’s biggest problems. Traditional solar cells require silicon, and silicon is an expensive commodity (exacerbated currently by a global silicon shortage). That means even the cheapest solar panels cost about $3 per watt of energy they go on to produce.

Nanosolar’s cells use no silicon, and the company’s manufacturing process allows it to create cells that are as efficient as most commercial cells for as little as 30 cents a watt. “It really is quite a big deal in terms of altering the way we think about solar and in inherently altering the economics of solar.”

In San Jose, Nanosolar has built what will soon be the world’s largest solar-panel manufacturing facility. California, for instance, recently launched the Million Solar Roofs initiative, which will provide tax breaks and rebates to encourage the installation of 100,000 solar roofs per year, every year, for 10 consecutive years (the state currently has 30,000 solar roofs). The company is ready for the solar boom.

NANOSOLAR: Solar-cell Coating

Executive Summary about Nanosolar by Silicon Valley

Solar panels are big, clunky, heavy, require special installation, and, if they break, replacing them can be quite expensive.

The PowerSheet is made from a layer of solar-absorbing nano-ink that is printed onto a foil-thin metal sheet.

Because of the ever-increasing costs of energy and the obvious environmental impact of burning up fossil fuels, turning to alternative energy sources such as solar energy is a priority.

Solar Batteries – Deep Cycle

Executive Summary about Solar Battery by Michael Motley

Batteries are separated into two categories, by application (what the battery is used for) and construction (how the battery is built). Deep-Cycle batteries are the battery of choice for most installations because of the way they are made. Deep-cycle batteries are made to be run completely down relatively fast, and recharged just as fast, constantly. The major applications for deep-cycle batteries are solar electric (PV), backup power source, and boat/RV batteries.

There are 3 main construction types at this time:

• Flood (wet)
• Gelled
• AGM

Flooded batteries are what most people think of when thinking of batteries of this size.

Gelled Batteries or Gel Cells are sealed, and some are valve regulated. They contain gelled acid that was gelled by adding silica gel, making like a battery acid jelly.

AGM (Absorbed Glass Mat) batteries are similar to the gelled batteries but they also have fiberglass mat between the plates of the batter, which is then filled with gel. These batteries are the premier choice if you have any concerns about spilling of battery acid.

The main difference in deep-cycle batteries is thicker plates. The thicker plates allow the deep-cycle battery to be discharged down as much as 80% over and over again. The battery with the thickest plates will last the longest

A battery cycle is one complete discharge and recharge cycle. How deep a battery is discharged directly affects its life span.

Battery Life

There are many variables to deep-cycle battery life. The standard flooded battery 1-6 years. In the deep-cycle family of batteries, the AGM has one advantage over the other two types in it’s class. There is a myth that you shouldn’t store batteries on concrete floors.

Battery Quick Facts

* Almost all batteries have to be cycled 10-20 times before being able to reach full capacity.

* Always keep vent caps on your flooded batteries when charging.

* Lead-Acid batteries do not have a memory. Use only clean water to clean the outside of batteries.

Solar Battery Technology
Executive Summary about Solar Battery by Anne Clarke

People are realizing that they can easily change the way that power is created. For two centuries the world has relied upon fossil fuel, mostly coal and oil, for almost every form of power. It lights our homes, powers our appliances and drives our cars. Unfortunately fossil fuels rely on combustion to release their power. Solar power is an effective way to harness the power of the sun, something plants have been doing for millions of years. It can produce more power during the day than the average home uses. Most houses will use less power during the day, and much less in the summer which is the peak power producing time for solar panels. To be effective this power must be stored somehow.

One popular way of storing solar power is by connecting the solar panels to the existing electrical grid, effectively turning it into a massive solar battery. At night power is taken from the grid as usual. Any power outages can still affect these solar panel set-ups, but no rechargeable batteries have to be used.

Rechargeable batteries are notoriously short lived and expensive. They either have low power flows for a long time with a good capacity, or they have high power flows for short times with poor capacity. Typical batteries, especially lithium ion, have high capacity for storing power, but deliver a weak output and recharge slowly. The ideal solar battery would be able to charge quickly, have a high density for storing power and be able to emit as much of that power as is needed.
