About Efficiency Of Solar Panels- Improvements In Technology

Because of technology improvements on solar panels these days, there has been a renaissance in this form of energy harvesting of late. Much of this new interest is fuelled by the need for overcoming the problems caused by fossil fuel depletion and excessive pollution of our airways.

Solar energy, using the free sunlight available to us has made the technology of solar panels of great interest to us considering our needs for low cost efficient power. Bearing in mind we have the use of twenty-four seven sunlight throughout the year, without cost it is not surprising that we want to make the best use of it.

It is strange, but true that few people seem to be aware of the numerous benefits of going solar and it is used quite sparingly on the whole. This may be due to the fact that often the solar panels used have not been as efficient as they should be. This situation has been dealt with by using bigger panels. The problem with this though is that the aesthetics of the home plus the higher costs involved are not especially attractive to the average householder.

Then again there is also the deeper problem of solar panels usage over dark and cloudy days and of course overnight when there is little if any light source available. On a more positive note, solar panel technology has made rapid strides over recent times to the point where radical innovative methods have come into use such as photovoltaic cells.

This technology has totally transformed the power, efficiency and costs of using the sun’s energy for home use. The size of panels has been reduced, but the efficiency of the panels has been magnified greatly.These photovoltaic cells are aligned on a bed of steel. The various cells are able to trap the many spectrum of sunlight. The panels have layers of cells, which overlap creating a powerful power-producing source.

On a brighter note, the technology and development of solar panels has made giant steps forward in current times and brilliant and clever products like the photovoltaic cell has been introduced.

The innovation here has drastically enhanced efficiency, costs and performance of the Sun’s power to households and commercial premises across the nation. This has been achieved by greatly reducing the size of solar panels and yet actually at the same time, enhancing their efficiency. The intriguing photovoltaic cells are the heroes in this story, and are bedded on a steel backing.

The shingles technology is simply one of many imaginative techniques of improvement on solar panels technology that are in use today through the magic of science. There is still much to do and a lot of research is ongoing to create the most efficient and low cost solar panels efficiency possible.

Material price for your DIY solar panels.

You know that technology makes possible to use clean electricity. But we continue using very environmentally harmful fossil fuels that are continually destroying the ozone layer. This ozone erosion is causing climate changes that will be very harmful in the long run. But the use of solar energy is clean and renewable.

Electricity from solar power is generated from the sunrays. It can be an unlimited resource. Power plants use very expensive fuels that harm our environment. The idea for adopting a solar energy lifestyle is far too interesting.

Today it is possible to purchase your own solar power panels. These panels are available online and range in price from $1000 to over $7000. Amazon has a very nice solar energy kit for close to $8000.

Using quality material can allow to a handy person to build very good solar panels. If you make them as a hobby, you will pay $3 per watt. If you want a 1.5KW solar panel, you can decrease the cost to $1.7 per W.

Cost per 150 W:

- Epoxy silicone sealer $35.

- Junction box $1.

- Clear silicone caulk/sealant $2.

- 50ft tabbing wire and 10ft bus wire, $20.

- Clear silicone caulk/sealant $2.

- Screws, aluminium frame $10.

- Junction box $1.

- Screws, aluminium frame $10.

- 3/4in 2ft x 4ft plywood panel $20.

- Clear plexiglass $20 (at low volume).

Then, the total cost per panel is around $250, it means 1.65 per Watt.

In the US, if you want to connect your panels to the grid your panels will need to have UL certification. But only if you want sell power.

In today’s world the DIY person can obtain everything that is needed to make your own solar power kit. There are several DIY books. They are all very good step by step guides that will show you how you can purchase from your local hardware store the materials needed to make your solar panels.

The materials should not cost more than about $200 or $250. This is well below the $8000 price for the Amazon.com system. Building a solar panel can be even be a great project for the whole family. Solar power is actually affordable for everyone with the right DIY manual. The videos they use are very informative and easy to follow along with.

The author is an electrical engineer that has been working more than ten years in the green field applications. He has created some home made solar panels. And wrote a lot of articles about earth for energy.

Ways Of Building Solar Panels

Before you start talking of residential solar panel, you must be acquainted with how you can generate it. Solar energy is the energy from rays of the sun otherwise called renewable energy source. With the growing negative effects of the fossil fuels on the ozone layer and high task on utilities by the government, the need to put these rays from the sun into maximum use becomes imperative.

However, before considering using solar panels in your homes you must consider some vital factors such as climatic conditions, quality of the solar panels and cost implications.

You can choose between three ways to get solar panels:

1. SELF-BUILT: Now you can build your won solar panels using very detailed guides. But, are this guide good enough?

These guides have pictures and diagrams that show how to assemble the panels either in parallel or in series, or the angle of titling of panels depending the required voltage. The manual will inform you where to get the cheapest panel for your installation. You can have one in less than $200.

2. COMMERCIAL BUILT: this is the employing of the service of experts to make one for you. This mode of generating electric energy through solar panel is so expensive but with warranty of good work.

3. ACQUIRING FAIRLY USED: this method is not common, because a minimum life span of one is 30 years. However, due some reasons such as a person trying to increase the quantity of voltage or relocating to a new place, a decision to dispose the existing one can be taken in this case you can take advantage and buy. It is usually economical when compared to making a new one.

If you build the solar panels by yourself, the difference in price is huge both financially and environmentally.

It will only cost you just the money to acquire such guide and less than $200 to make a residential solar energy. Invariably, making it an easy task of recouping your initial investment and continue enjoying the subsequent years of its use without monthly payment of government tax. In addition, making one your self improves your technical know how, which you can use in making money by building for others without much hassles.

However, initial attempt of building a homemade solar energy using a manual has its challenge and that challenge is that it takes longer time than required to make one when compared to what it takes the professional or commercial built companies to make one.

In summary, with the long lasting benefits of making a residential solar panel, its environmental friendliness and little cost involved when using the best manual makes it a great deal to acquire one before the demand will surely move the price upward.

The author has BSC in engineering from Cal state University, Los Angeles, USA and MSC in power and energy generation from George Washington University. He has created some homemade solar panelsguides. And has written a lot of articles about diy solar guides.
