Tips on Solar Power for Home

Wednesday, January 11th, 2012

The time has arrived for the world to wake up to the alarming scenario of energy crisis. This is no more a situation of single dimension; the other dimensions of it being depletion of the conventional energy sources, global warming, severity in climatic changes and their effects being manifold.

Check out some of the methods of harnessing the tremendous solar energy which is mostly wasted and which has the potential of solving a majority of the above stated global problems.

  • Solar water heating equipment is one of the most common and predominant usage of solar power for domestic purposes. Water can be heated normally up to 60 degrees Celsius and can hugely cut down on the electricity bills.
  • Solar powered heating, ventilation and air conditioning systems commonly called HVAC systems can be deployed at residential places. Homes with modern architecture can accommodate construction with specific materials which can act as heat store. This acts as a heater when surroundings is cold and acts as a cooler when it is hot.
  • Cooking using solar power is possible by solar cookers. The incident solar light energy using concentrated solar power systems is used to boil the water and thus cook the food. This is can also be used as an oven, milk heater and so on.
  • Solar powered vehicles are off the beat cutting edge technology automobiles which use solar panels for trapping more and more solar energy and convert it into useful mechanical energy. There are cars, bicycles, boats and even aircrafts which are solar driven.
  • Photovoltaic cells which are commonly called solar cells are devices which convert incident solar radiation into electrical energy. These cells can be instrumental in lighting and other electrical needs of residential units.
  • By switching over to solar power for simple equipments which we use in our daily lives, we can not only save a great deal of money but can be a significant shift towards utilizing renewable energy sources. Solar powered calculators, emergency lamps, decorative lightings, watches and other electronic gadgets can eliminate our dependency on fossil fuels and chemical sources of energy.
  • There are these and many more ways of utilizing solar energy; but all it requires is a one time investment and then reap the benefits on a long run. Another advantage of using solar powered equipment is the relative low maintenance factor. The governments of most of the countries which are signatories of the UNFCCC are unconditionally giving investment and tax benefits for installations to shift over to solar energy for power requirements.
  • What more? There are facilities for your house hold equipments to generate solar power and sell the excess to the power grids of the native country at the same price which is collected from you for using it!

As individuals, if we think there is nothing much that we can do about the global problems like climate change, global warming and energy crisis; then we can’t be more wrong. To save a better and healthier tomorrow for your kids and for all the coming generations, ACT NOW – ACT FAST!

Energy Solutions? The only way is up!

Thursday, October 27th, 2011

When considering energy solutions the only place to look, is up. Look up to the sky and see the newest of our clean, green energy solutions shining down on us.

The heat and strength of the suns rays can be easily converted to solar energy, which can power homes and industries. The rays are caught by the solar panels that are usually placed on the roof of your building. They are fed into an inverter, which converts them to energy of the right voltage for use.

Your Own Power Generator

Every time the sun shines, solar panels are creating energy - often more than your household can use. Even on a cloudy day your solar panels are still generating power. If you are connected to a grid, (which you will be unless you are in a remote area) the excess power can be sold back to the power company. Just imagine your energy company paying you rather than billing! It is like having your own power generator sitting on your property.

During the night or in periods when there is no sunlight consumers can buy their power back again and be comfortable knowing that it is clean and renewable energy.

Solar energy can power all your appliances, your lighting and even your hot water service.

The Cost Factor

While the initial investment can be expensive, consumers save money in the long term by generating their own energy. The actual equipment has no moving parts so it will last for a very long time with no wear and tear or replacement costs. Adding solar panels to a home can sometimes increase its value in the market, too, as buyers see the benefits in reduced power bills.

Solar power is reliable and continually available. It does not harm the planet and it is easy to generate. It can power small buildings and large communities. It is affordable and even has the capacity to generate an income for you.

When you are looking for energy solutions, look up. The answer is waiting for you in the sky!

Under Your Own Steam – How Small Businesses Can Generate their Own Electricity

Thursday, October 8th, 2009

Small businesses will always strive for ways to reduce their outgoings, particularly in an unfavorable economic climate such as the one we find ourselves in. One good way to reduce expenditure is to look at utilities; switching suppliers or reducing usage can help with energy bills, although it can often be a complicated task.

One way that small businesses are beginning to benefit from attempting to reduce their outgoings is through generating their own electricity. Previously the costs associated with generating electricity prohibited small businesses from considering this option, but  generating your own power is becoming a relatively affordable thing to do.

Increasingly generating electricity is becoming a viable option for small businesses, who can pocket the reduced utility bills, and even selling surplus energy back to the National Grid. Here are three ways in which small businesses can generate their own electricity.

Solar Panels

There are two ways in which solar power can be used to generate electricity. Concentrated Solar Power (CSP) uses the sun’s energy to boil some water, while Photo-Voltaic (PV) solar panels convert the energy directly into electricity.

Photo-Voltaic solar panels are still reasonably expensive, but can generate a significant amount of electricity. These are solar panels which use light, so they can still generate power even on grey, overcast days although obviously not as much as long, sunny days.

One problem with solar panels is that they tend to mean power is only available during the day, when the sunlight is casting onto the panels. For domestic properties this can mean that solar panels are not appropriate, but for many businesses the majority of energy use takes place during office hours, when the sun is shining.

Either way, it will be useful to store the energy being generated, so most PV systems come with batteries which can be charged.

Another solution is to sell your energy surplus back to your electrical supplier (as long as you are still connected to the National Grid) and then paying them for your electricity when the sun goes down and you’re no longer generating power.

Wind Turbines

Wind turbines are experiencing a rise in popularity recently, particularly due to the shrinking price of micro-turbines in DIY stores.

While it may seem like the perfect solution, with the wind blowing all day and night, the amount of electricity which can actually be gleaned from these wind turbines is often negligible, depending on the specific location.

Wind speeds are always faster above ground level, at heights above an average house. The wind disturbance caused by other buildings around it further decreases the amount of electricity which can be generated.

A large turbine on the edge of a building where it can receive clean, fast air is more likely to generate a decent amount of energy, but there is also the annoyance of the noise of the blades spinning around.

Combined Heat & Power Units

Another method of generating electricity which is bound to become more widely available in the future is the use of Combined Heat and Power units (CHPs).

While they were previously only suitable for large buildings like factories and universities now small CHP generators are on the market, running on natural gas. The heat generated is channeled to provide heating and hot water for the building and is no less efficient than a modern gas boiler.

Future Benefits

While the technology required to generate electricity may still require a sizable initial outlay, the benefits should be apparent for years and years for a small business, with greatly reduced energy bills. As fossil fuels become scarcer the price of energy is bound to keep rising, so it’s no surprise that forward-thinking businesses are beginning to attempt to run under their own steam.

While these opportunities for businesses to save money on their energy use are still worth investigating, many of the technologies are not yet developed appropriately for businesses, and should probably be considered as future prospects rather than immediate changes.

Save Money Now

Most small businesses could be saving money now by switching business electricity supplier and employing energy-saving measures such as using natural light and ventilation where possible, avoiding leaving equipment on standby and turning off lights in rooms that aren’t in use.

Solar Cells from an Inkjet Printer

Thursday, March 6th, 2008

Konarka Technologies has recently released a press release regarding the first ever demonstration of inkjet printed solar cells. According to Konarka’s president and CEO, Rick Hess:

Demonstrating the use of inkjet printing technology as a fabrication tool for highly efficient solar cells and sensors with small area requirements is a major milestone

Konarka Technologies is a company that specializes in organic photovoltaics - solar cells made from plastics (as opposed to silicon).

The ability to print solar cells from an inkjet printer opens up the possibilities of how solar energy can be produced. Konarka is interested in working with partners to explore innovative ways of integrating solar power into products. For example, they have already partnered with Air Products to develop windows that generate electricity.

Although organic photovoltaics is not as efficient as using silicon cells - organic photovoltaics is around 5% efficiency, compared to 15% to 20% efficiency with silicon solar cells - it does allow for a wider range of solar applications, which can only be a good thing. Furthermore, Konarka’s chairman and co-founder, Howard Berke has said that he expects organic photovoltaics to ultimately approach silicon’s efficiency.

I notice that Konarka are billing this as the “first ever demonstration of inkjet printed solar cells…”. I suspect that this is because it’s not the first time we’ve heard of solar cells produced by printing techniques. A team of Japanese researchers have also succeeded in doing this.

In any case, it’s good news for the future of solar energy.
