Cheap Solar Panels - Types of Solar Panels

Share This

Solar panels are classified into three primary types: monocrystalline, polycrystalline and amorphous. Each type has its own benefits and drawbacks, which makes research essential before purchasing a solar panel for your home or business. The U.S. Department of Energy states that solar panels are given an efficiency rating based on the percentage of energy the panel is able to effectively capture and convert into usable electricity. 

Solar panels transform solar energy into current electricity, which if the prime purpose of any solar energy device. As science and technology forge ahead, there were several types of solar panels invented and distributed within energy industry. Moreover, modern advancements allow production and usage of solar energy not only on large enterprises, but in households. Solar energy becomes more and more available; one of the recent trends is embedding solar panels into small gadgets and devices. 

Therefore, the variety of solar panels is likely to encourage major improvements in everyday livelihood. 

First of all, solar panels might be classified according to their capacity. Three main types might be recognized: 
  
Universal panels, which might be used in field environments. Such panels are usually appreciated by travelers, who are eager to deal with active and ecotourism.

1. Small panels, which are embedded in small devices (such mobile phones, electronics, etc).

2. Solar cell panel, which might be usually seen on solar energy plants.

In addition, the whole range of solar panels might be divided in three groups according their structure. In this context, there are photovoltaic cells, solar power stations and solar collectors. Each type might compete in popularity and distribution, which is why they are worth considering in details.

Photoelectric converter may be defined as a device processing power via the photovoltaic effect. Solar panel is formed, when several photoelectric converters are united.  Photoconductivity is a main factor, which defines optical properties, and, therefore, the effectiveness of the panel. This phenomenon is preconditioned by the internal photoelectric effect, which occurs while irradiating the semiconductor with sunlight. Nowadays the United States are world leader in usage of photoelectric converters, which hold 405 share on the global market. A lot of companies also deal with producing materials, required for photoelectric converters. They are HEMLOCK and USA MEMC, AsiMi, SGSil (the Unied States), Wacker (Germany), Tokuyama Soda, Mitsubishi MaterialPoly Si, Sumitomo Titanium (Japan) and Italy MEMC (Italy).

Solar power plant is a solar installation, which uses concentrated solar energy to drive other various machines: steam and gas turbines, thermoelectric cells, etc. Surprisingly, solar plants are used not only to generate energy, but facilitate other industries as well. Among other specific purposes it is appropriate to admit heating and desalination of sea water. The main point of plants structure is lenses, which help to concentrate energy. In particular, nowadays they are replaced with large mirrors due to big weight and high cost of the first ones. Mirrors are usually made of conventional glass or polished aluminum. Solar power plants are the prerogative of countries located in tropical areas (Montalto di Castro PV Power Plant and San Bellino PV Power Plant in Italy, Lopburi PV Power Plant in Thailand). However, the biggest one is located in Ukraine - Perovo Solar Power Station.

Solar collecting systems are low-temperature heating units, which are used for autonomous hot water supply both for residential and industrial premises.Solar collectors also might be divided into three types:  flat (represented with element-absorber, which absorbs solar radiation), vacuum (laminated glass coating) and collector-concentrators (mirror surface).

CONCENTRATED SOLAR

Concentrated Solar uses reflectors to concentrate the sun’s rays onto a collector. The collector either stores the heat energy or uses a heat engine to convert it into mechanical energy.

The range of applications of this technology is enormous, and varies from the small solar cookers, which are becoming popular in developing countries, to vast fields of utility-scale mirrors, such as those employed by Solar Tres, a concentrated solar power (CSP) project slated for construction in Spain. This installation will focus hundreds of times the sun’s energy on a single collector tower, producing 5 megawatts of electricity using liquid sodium as a heat exchanger. Additionally, it will have the fringe benefit of being one of the very few renewable energy technologies to come out of a James Bond Movie. Take that, Biomass!

Cheap Solar Panels - Choosing the Right Solar Installer

Cheap Solar Panels

A solar power system is one of the biggest investments a homeowner will make, so it's important to make sure that everything is installed properly and built to last.  Components vary quite a bit in terms of electrical output, form factor and weight, but most panels will come with a 20-25 year warranty, making solar a long term investment, dependent on a strong foundation of a quality install.

The first tendency when looking for an installer will either be to go for the cheapest option or to assume that the highest priced option is the best and go for that.  The better choice will most likely be somewhere in the middle.  A good solar installer will manage the entire supply line, meaning they'll source all of the components for you and take care of everything from start to finish.  This typically means that they'll get wholesale prices on the materials and pass some savings on to you.  The danger in going with the cheapest installer is that they may be providing a cheaper service by using lower quality components.  Remember that although a solar panel can last from 25-50 years, critical components like power inverters are not as resilient, so making sure they're top quality is the best way to ensure your entire system functions for decades.

Finding the right installer will be much like finding a home builder or a general contractor for an addition to your home.  There are so many elements involved in purchasing, planning and installing a solar power system, which a good installer will need to know a bit about everything.  The installer will be handling the purchase of the equipment, any rebates and programs that you qualify for as well as the actual installation, so this will go beyond the scope of a typical handyman.  The better business bureau or community review websites like yelp.com are great resources for weeding out the average from the excellent.

Finally, make sure that whomever you chose to install your system is someone you trust and are comfortable with.  There is a tendency in many service industries to push higher priced products or additional services that may not be necessary in order to generate more revenue.  Keep in mind that you're the customer and you need to be confident and comfortable with every aspect of the job before signing the contract.  If at any point you feel uncomfortable or pressured, consider working with another installer.  The installer will come and go once the job is complete, but you'll live with the solar power system for decades, so making sure you get exactly what you need is the most important part of the whole process.

Most of us are aware of solar power these days. A huge number of gadgets feature solar panels these days while solar photovoltaic panels adorn many a rooftop across the world. But what about solar-powered cars? Are they a reality or the stuff of science fiction? According to specialist website called Solarpoweredcars.net, solar powered cars have been around since the 1970s while the first completely powered solar car was developed in 1984 by Greg Johanson and Joel Davidson.

The model was called Sunrunner and was totally powered by solar energy. It featured a 1.2kW solar array, a 1hp wheel motor and a MPPT controller. It had no batteries. The Sunrunner entered the Guinness Book of World Records when it reached a top speed of 41 mph. Greg did the piloting during the feat. These days Greg runs a solar energy company called Solar Electrical Systems, which installs PV systems on residential and commercial buildings.

But how can solar energy power cars? Through photovoltaic (PV) cells, which convert sunlight into electricity. Together they form panels that get exposure to the sun, which in a car could be the whole surface of the car, but mainly the rooftop. Solar power makes the car move and is stored in a battery to that it can work at night and on cloudy days. 

At this stage solar powered cars are an expensive proposition as cells cost anywhere between $10 and $400, depending on their level of efficiency. Besides, most models proposed so far only carry one person. But as a concept, it is an absolute wonder. Can you imagine driving a vehicle that relies solely on the energy of the sun? You can’t cleaner than that. One may say that electric cars fed with solar electricity are, in a way, solar powered cars. In this case, it is already happening. But cars equipped with solar panels to transform sunlight into fuel for now remains a dream, albeit a beautiful one.
