Your electricity bill, "Sky High"? With summer approaching, we are afraid of the price it will cost you your house cool in summer?

Would it surprise you to know that many homeowners are the sun's energy in an effort to reduce energy costs? What was a futuristic dream is now a present reality.

Solar systems are now accessible to the general public. Depending on your budget, there are many systems to choose from. You can starta small system with one or two of your equipment, or you can go all the power, and a large system that needs all the energy in your home turn.

Solar energy measured in kilowatt hours or kWh. In some measure, a 1000 watt, kilowatt equivalent, so 1 kWh equals 1,000 watts of electricity per hour. Use this formula to the form of energy required (the element amperes) times the voltage (110V or 220V) to use the kWh per month. Thus, an element at 2.2 amps ata 110 volt system will need 220 watts to run or.22kWh.

Now back to the focus on costs, a small solar system that lets your computer and some small electrical appliances can be used is usually run about $ 700. A larger system, which is a kilowatt (kWh), which can reduce energy bills by up to 50% can produce run $ 10,000.

How solar systems? Solar panels convert sunlight into electricity. Sunlight is our most powerful light is then absorbed by solar energyDishes. Photovoltaic (PV systems also) related to solar energy systems.

We see things every day that use solar power. Calculators and watches are now powered by photovoltaic systems. The more sophisticated systems can not only produce electricity at home, but can produce enough energy, they also used to provide power for cellular towers.

The solar cells are integrated in the production of solar modules. You may have seen on the roofs of buildings and homes. SeedsScale form silicon photovoltaic cells. When the sun produces solar energy absorbed by the semiconductor and then converted into electricity. panels to increase energy efficiency called "thin film" is

The length of the house and the average amount of electricity consumed, which determines the size of the energy system you need. Make sure you get accurate measurements of the surface area of the house, and several months of electricity bill for the figureaverage energy required.

According to the Department of Energy, the average home uses 920 kWh per month in 2008. The United States has used a whole 4,000 billion kWh per year! That's a lot of energy! Did you know that the sun consumes more energy in one hour around the world in a year?

Although it has become more affordable solar home systems, are still quite an investment. If you can run a house of a medium-sized solar power system as high as $ 40,000. Do not bethese numbers scare you. In the calculation of costs and benefits, a period of time, looking ten to twenty years.

Around the camp, many government with tax incentives and other discounts as an incentive. Make it look like you could, for all programs solar systems have been at home. Some governments are even field by providing funding for solar installations.

In the long run, how people think that electricity bills a thing of the past. In fact, manyThe owners of solar systems in their systems to maximize solar energy, rather than resale.

net metering provides the owner of a solar energy storage system, the ability to sell their excess, unused energy back to their suppliers. You can make your solar system you make money.

Solar energy can be directed to the need of a home on the grid. The cost to run the cables from the electrical network is astronomical.

This makes a solar systeman incredible savings. Remotes are the Third World countries now have a choice to walk instead of a solar-powered electrical lines go.

If most of a solar home system, start first by cutting the amount of energy used at home to get. Make sure that the overall picture, if it is based on the price of investment.

As more people choose to go with solar energy as the main source of energy, we'll see fewer and fewer greenhouse gas emissions globallyHeating, which benefits all.

Time for a new amp?

I am often asked for advice buying a bass amp. Although there are many resources online and elsewhere, I'll throw in my thoughts on the subject. We hope to obtain valuable information.

First you need to consider the budget. This problem can greatly impact on your purchases.

You need a better amp soon, or it can wait a while 'until you can afford what you want?

Portability – Transport and mobility areimportant factors to consider. I prefer to take smaller and lighter items such as large, heavy objects, in contrast – been there, done. (If you have always roadies, portability is not a problem for you.)

Sound – This is a very important factor and depends on kinds of styles and techniques that you play. If you have found your (current) sounds like, then check what equipment to use the bass player. Remember, however, as Jaco said: "The sound is, in myMani. "

Solid state, tubes (valves) or a combination of these and other technologies?
The forms are pre-amp your sound and a stand-alone unit. It can also be integrated with an amplifier and / or a speaker. The latter is usually a "combo" called.

Watt – This is a common misconception that the speakers should have more power amp much more than the RMS power. Often the bass player and inexperienced sellers believe that a 150W amplifier combined with 300W Speakeris a good combination, safe and powerful. It is not necessarily so.

Ohm – 150W 8 ohm amp running a 300W 8 ohm speakers run. 80W power – not because of the low. Bass requires freedom. When you press the volume and do not have the ability to distortion and speaker amplifier and damage can be.

My advice: how many watts is unreasonable Get Amp 500W – 800W is not. This also works with a 300W speaker cab to work. Why? Without being technical, here is aAnalogy: A large machine with a V8 engine is purring comfortably at 80MPH, while a small car is half the size of the engine much more difficult to work with the same speed. The loudspeaker is driven very hard with the amp is not small at all with the amp with more space, because the charge amplifier is pushed.

If you are not satisfied, go to your local music store, plug a speaker in a 50W and 500W amplifier to control the bass sound. Then connect an amplifier speaker 100W 1000Wto compare. (Now we're playing again.)

Also check out the sound of 8 ohm speakers, compared with 4 Ohm cabs as well as combinations approved by the manufacturer. As always, let your ears decide. I prefer the more saturated sound speakers 8 ohms.

combinations – EQ graphic equalizer, parametric, semi-parametric or a variety. What suits you? Usually the store employees are aware and supportive.

Compression – The most high-end bass amplifiers have a good compressor. ATouch of compression is not to be overlooked in your sound. All recordings have a degree of compression and the bass is to play a great resource for living. (All my classes are recorded with low compression. Have you noticed? If not, fine.)

If you separate preamplifier, amplifier and speakers Now, you can always combine. This is a great way to reach your final sound. You can try, tube / solid state amp combinations with the speakers and speaker boxes in various sizesand quality.

Many leaders now have the option of mixing tube and solid state preamp. Some do amp simulation (from well known and successful combinations) a. Sun can find out what works best.

My current setup (for the last 14 years) is a head with two 250W power amplifiers, as well as all other shbang DI output control, a good compressor, semi-parametric EQ, shelving (graphic) EQ, headphone jack, tuner and effects in / out and much more.And very important: a tube pre-amp. This makes the amp sound better as it warms. I have both amplifiers in a bridge circuit that gives me 600W RMS 350W RMS into a 2×10 cabinet with a horn attenuateable. The car can handle peaks of up to 800 watts.

A note on the speaker boxes – 2×10 has about the same size as the 1×15 speakers. Therefore, the 2×10 has a similar amount of deep bass as the 1×15, even better, faster, clearer answer, so it is good for 5-string bass.

Although theThe above information may, in depth, is not as deep. Many issues were not mentioned, and I suggest you continue your search.

Bass good luck!

Solar panels are by far the most expensive element of an installation of solar panels. Understanding of the characteristics that differentiate a good solar panel is not a bad thing so easy. In several installments, I would write a guide to each of the main criteria to look out for. I'll try to keep it as simple as possible, but it is something that many people ask me, so I think it's a good idea to discuss these issues in depth.

First, I like to discuss solar panelEfficiency. This determines how effective a solar panel to convert sunlight into electricity for a given area. The advantage of having a solar cell is the highest return that you get more power from a small area available. For this reason, high efficiency solar panels is usually a high price for the domestic market, where space is more limited. High efficiency does not necessarily mean better quality or reliability, however – these topics are coveredlater. Not even a higher return means better value, in many cases, lower efficiency panels are used for convenient use in places where space is not as critical.

First of all, how to find the efficiency of a solar cell? It's easy to find out for yourself. Remember that the power of a form of solar energy to visit, where is "standard test conditions." This means that the output is measured when the plate is exposed to a very bright lightwith an intensity of 1000 watts per square meter (1000 W / m2) at a temperature of 25 ° C. This is usually expressed in watts (185W or 230W for example, etc.) and is the power you get when the sun is very strong will. You can then multiply the length and width of the module (which is represented in the data sheet) to access the form. With the power module in watts and the standard test conditions of 1000 W / m 2 to determine the efficiency of the module as follows;

Efficiency = power out / energyin the power module = / (width x length x 1000 W / m2)

to know in evaluating the efficiency solar important that each solar cell with efficiency greater than the total solar panel (or module) through a vacuum. Therefore, make sure you know what value you are looking for.

In general, the solar panels you come across in the UK is silicon (I have previously discussed thin film), so that the discussion is made here to focus on these. The highest efficiencysilicon solar cells available today are effective from 17% to 18%. The efficiency of silicon solar cells, increasing the R & D, but the improvements are incremental and slow, because there are a number of fundamental limitations to increase the efficiency of silicon solar cells that any drastic improvements highly unlikely that the average values near future. Maybe I'll describe these restrictions in another article.

The most important factor that you meet with a yield of the module, is whetherThe form is mono-or multi-crystalline. In English, this means that solar cells are easily made from mono-or multi-crystalline silicon. mono-crystalline solar cell consists of a disc from a single crystal silicon are very pure and very efficient from a number of weaknesses. multi-crystalline solar cells, which contain more crystals are about 1-2% less efficient, but are generally cheaper to produce. Personally I think that makes sense in the rule of using mono-crystalline cellsfor domestic applications, where space is at a premium and multi-crystalline cells in larger installations.

Another factor affecting the efficiency can be anti-reflective coatings. These are becoming more common. Nearly all the solar cells directly texturing them to reflect and now reduces many solar modules come with anti-glare glass. This generally consists of a molded glass that can be seen as a model of stain, if you look closely. Improvinganti-reflective coatings is difficult to determine, although some manufacturers require improvement in production efficiency by more than 5 percent.

When you install a solar system is your goal should always be the best return on investment, which means the maximum power at the lowest price, without risk to reliability and depends on many factors to get along with ' efficiency. There are a number of other technologies on the horizon that might be possible to improve the efficiency of small quantitiesnothing is a drastic change overnight. Rising prices for solar panels continue to decrease rapidly the volume of production (in the same way as many other technical products such as computer memory), but these price decreases will be matched by savings in feed. So do not worry that the installation of modern technologies and solar panel replaced by a miracle tomorrow. are working in the field you better insight into what is on the line.

To shed light on this problem we need to get a brief understanding of how different devices to power. In practice, the electrical devices into three groups by the way they draw energy or power are distributed by a power source. These groups are resistive, inductive and capacitive. To make a little 'more confusing, some devices can distinguish three types of power!

Resistive loads like incandescent lamps (such as a filament bulb cable) always draw aconstant power in watts from the wall. For example, a 60-watt bulb with 60 watts from the wall at all times. For fairly obvious reasons to resistive loads are by far the simplest device for an inverter as the power in watts, that take is the same and will remain for as long as the device that is running on.

Inductive loads, such as a refrigerator or other device with an electric motor, requiring a great influx of power (surge) for theCommissioning and then runs back tend to move lower and more stable performance for the rest of their operation. Inductive loads contained wire coil weight (such as motors, transformers, chokes, coils, etc.) and when the device is switched on the weight of the coil of wire a wave of current, magnetic field, these devices draw shapes work properly. This magnetic field (or Lux, as is known) is stored as a kind ofEnergy.

The most common are inductive devices, refrigerators, followed by compressors, transformers / chargers, pumps, power tools and fluorescent tubes. the necessary stimulus because these devices can draw power 2-6 times their normal power operation and can be performed to provide a 200 watt refrigerator, you need a 600W or 1000W Power Inverter also in order to function properly.

Please note that some electrical appliances such aslarge refrigerators and air conditioners, which have very high starting current requirements because they have to start the engine at full inductive load. It is strongly recommended that these devices not be used with an inverter as the requirements of current is too high and should be driven by an engine-driven generator.

The capacitive loads as many televisions, computer monitors, amplifiers and other electronic devices need aspike-rush current if not used for a long time. This is usually on these devices with their large power capacitors, which immediately put in charge if the unit is on need. If these electrical devices are not for a couple of days later, the capacitors used in power is slowly, gradually and go slow. You can order these devices, simply by changing the judges work a couple of times the fees until theCapacitors sufficient to activate the device, and should work also continue to operate normally.

Efficiency in photovoltaic solar cells, the ability of a panel to convert sunlight into usable energy for human consumption. Knowing the performance of a panel to choose the right pad for your PV system important. For smaller roofs, panels more efficient is necessary for reasons of space. As a manufacturer of determining the maximum efficiency of a photovoltaic solar panel anyway? Read below to find out.

First, let's say first of all,that the maximum power that is independent panel announced as Pmax 200W 200W plate efficiency. This is the area of solar cells up to 200W, which as efficiently get the panel determined. The jury determines the efficiency of a panel of power per unit area. The maximum efficiency of a photovoltaic solar cell is given by the following equation:

ηmax (most efficient) = Pmax (maximum power) / (ES, γsw (radiation incident flux) CA * (rangeCollector))

The flux of radiation incident could best be described as the amount of sunlight hitting the earth's surface in W/m2. The assumption of the incident radiation flux in standard test conditions (STC) using the manufacturer is 1000 W/m2. Note, however, that STC includes several assumptions and depends on your geographic location.

Now let's do an example calculation to determine how manufacturers calculate the maximum efficiency of solar cell in STC.

Suppose we havea 400W system with an area of 30 m2 and determine the maximum efficiency of your solar system at STC. Your first step would be the area of the panel "to units of square meters, to convert:

30 m2 x 1 m / (10.76 m2) = 2.79 m2

(In determining the efficiency, I personally dimensions of the frame in the calculations. Even if they receive needed for structural purposes, are components of field)

Now that youYour Pmax (400W), ES, γsw (1000W / m2) and AC (2.79 m2), you can plug the numbers into the equation of efficiency, in which all units of erase, and then multiplies the value of 100 % pass rate for efficiency:

ηmax (in percentage) = 400 W / (1000W / m2 x 2.79 m2) = 0.143 x 100% = 14.3%

This would be the maximum efficiency of your solar system, not the least that can be displayed on the panel data are unclear.

So ifThey determine what the solar panels are right for you, think about how important the efficiency of the panel to pay a premium price. Maybe you have a roof with a large area that would be ideal for the placement of solar panels, and thus lower costs and less efficient panels would work for you. If the roof is limited, however, you can use efficiency that are determined to reach your plate to the desired performance in a limited area.

Now that you've decided, is planning to build a wind turbine you need to build wind generator. We have good plans that you too, where you will find free resources to find batteries, towers and blades too.

No need to spend thousands of dollars on a new wind machine home. It is simply a 1000 watt wind turbine for less than $ 100 in just build a couple of days.

What you need to get started?

• Simple tools for household puzzle, cordless screwdriver,Key, etc.

Wind Generator Detailed · Plans

• A good help to keep stuff, while it is cut and assembled

Degrees and a job, or any room in the basement or your garage.

The first thing you do is a direct current motor, the current source is called a. The plans show where to find cheap, usually less than $ 30.

The DC motor can be delivered right to you, as a rule, only a few days.

During the wait,can build the rest of the machine. A tower is usually used to quickly find the TV towers can be used has been removed.

Wind power plant construction plans that show exactly where to find deep cycle batteries.

Construction of the leaves can be difficult, but just follow the instructions carefully and you'll be fine.

For the construction of a wind turbine blade 1000w you need at least 4 feet and a blade diameter of about 8 meters.

These should be made of wood.Straight-grained spruce or cedar clearly the best for this project.

You can use PVC pipe for blades under 3 meters. Wood is much stronger and more durable.

All types of recycled material can be used in this project also Towers (as mentioned), the body and tail as well as the batteries become too much.

Building Wind Generators is become very popular lately to see at home, wind turbines popping up all over what we do. And no wonder?

When you start freeElectricity for the home, only to wind turbines that rotate, you will not be able to stop smiling. But not enough, you can build your own solar panel.

Did you know that electricity tariffs are expected to double in price at the end of next year?

Is not it time you took some steps to support your family meet this expectation energy crisis? Let's start.

The best place to learn how to build a wind generator is the power to find the DC motor is used to produce wind turbines for home wind. We found the best sources for engines, hubs, and also the towers, and most are easy to find or even for free at times.The current motor to drive a system of wind power at home usually costs about 30 dollars and can be delivered directly to your door. It is interesting to note that this part is the most expensive thing you have to buy.

Why arewind generators commercial products so expensive? The machine 1000w we recently saw a cost of $ 3200th This is just a lot of money to start with renewable energy why not buy a wind generator in every case, if you can only learn to build?

What do you need?

· Plans detailed on how to build a wind generator

• Some work in the shop or garage

· No special tools required puzzleKey, etc. only

· About four days to complete the work

Some of the parts must be ordered separately as the DC motor in order so that this first. The sources are right there in the plans. While you're waiting to get to other parts needed to mount and start the blades for wind turbines.

You can use the blades from PVC pipe of large diameter for wind turbines up to 5 meters in diameter. Each sheet may be about 30 Inches long in this case. Because you total output is produced directly with the diameter of the blade, a knife is preferable to have larger size if you have more power to be generated. Makes sense, right?

In the case of PVC blades, as you have less than 5 meters in diameter, this design is only about 500 watts of power, not enough to make a great contribution to the electricity grid is limited. This is sufficient for the light and the TV and computer with a fair wind to run the batteries> Generator so the PVC is a good start if you have access.

larger diameter of the blades, although the tendency to break during use of PVC, we recommend wooden blades when you start to learn how to build a wind generator. bladed wooden spruce, cedar wood or wood are made clear, however, used free of knots so tight. Most other parts are available free of charge, including the use of towers for the wind turbine in your new TV home. Once you get those partsIt 's just a matter of implementing all together on the plans.
