Reducing Household Electricity Bills

Tags: , , , , , , , , , , , , , , , , , , ,


High Costs of Electricity in USA have become discouraging for thousands of consumers. As a result, people have started looking for the alternate sources of energy. Credits and discounts are available for the installation of solar electric system for household and business venues. For instance, the State of California pays a rebate for using solar power system.

In addition, the solar power system is available on lease in a number of states. New solar systems available for domestic users provide free energy from the sun. This can be used to run TVs, refrigerators, pumps, computer and many other appliances.

Need Of The Electric Power Company

With the advent of solar electric system, utility consumers have become independent in producing power for their domestic use. Consumers do not have to rely on Power Company alone and they can meet their utility needs. However, they remain connected with a Electric Power Company.

Convenience Of Solar System

Solar system is very simple to use. It does not require any special monitoring and is a plug and play utility. In addition, there is no issue of moving parts and noise. Solar modules are assembled under the heat and light of sun and generate power through out the year. Solar modules cover a warranty of 25 years but they last for about fifty years.

Configuration Of Solar Electric System

The Solar Photovoltaic Array is a unit that collects the energy from a sun. It is placed on top of a roof in a south direction. Hence it gets maximum exposure to the sun light. Energy conversion unit (an inverter) receives energy in the form of direct current and inverts it into alternating current.

Features Of The Solar Electric System

A few salient features of the Solar Electric System are highlighted below:-

1. Functions Of Inverter

AC or alternating current is used in houses and the sockets are made to receive it. Inverter produces the AC current from the DC that it gets from the battery. This is in turn fed to a utility meter and a grid. While producing power, the utility meter may have to slow down and at times run backwards.

2. Net Metering States

Net Metering States like California charge full retail price for the power production. Consumers get a credit from company for producing the excess power. Utility companies located in a state with net metering laws, issue a credit for the full retail value of power, households or businesses consumption.

3. Credit for Excess Production

Credit for excess production is carried forward to the subsequent months. At the end of a year, the solar system power generation restarts. If any credit is remaining, it will be treated as zero. So it is important to set a yearly limit for the scale of production and consumption.

4. Batteries For A Solar System

 It is a personal choice to use batteries. Both kinds of the solar systems are available in market that runs on battery or even without them. The system automatically shuts down in case of failure with a battery-less system. No electricity is available at homes until a utility company restores the power. This is a safety measure installed by the power companies.

5. Feeding Power During Power Failure

During power failures, utility company sends a lineman to repair power lines. System does not allow an inverter to operate during power failures.

Competitive Costs

Some factors influence the costs of a solar system. The Size of a system, required energy and a location of installation, set price of a solar system. Average cost of an installed system roughly estimated about $36,000 for a home of 2500 square foot.  This estimated cost is about 4 Kwh at $9 per watt. This estimation is not accurate. It just provides an idea of the cost.

Determine Size Of Solar System

The size of a home does not determine the size and the consumption of a solar system. Just call a representative and ask him to calculate the size of a solar system for your home. He will call your utility power company and get your monthly or daily electric usage in kilowatt hours. This information is also available in the copies of electric bills.

Tax Credits And Rebates

High Costs of Electricity in USA dissatisfy thousands of utility consumers. They enjoyed tax credits and generous discounts. Credits and discounts are available for the installation of solar electric system for household and business venues. The State of California for instance offers 15% tax credit and $4000.00 (per kilowatt) as a cash rebate for the solar electric system.

Photovoltaic panels

New solar system generates free energy from the sun and runs TVs, refrigerators, pumps, computers and many other appliances. Photovoltaic panels produce power directly through sunlight. Photovoltaic panels use semiconductors made up of various components. These panels are first preference of residential solar system.

Solar Thermal Collectors

This is another way of trapping, absorbing and transferring heat from sunlight in the form of warm water or air.  Solar energy system has a long way to go. It moves in a right direction with better incentives.

Configuration Of Solar Electric System

The Solar Photovoltaic Array is a unit that collects the energy from a sun. It is on the top of a roof in a south direction. So it gets maximum exposure to the sun.

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,


All the solar thermal plants in USA are not pollution-free. It is because they use different kinds of fuels as well. They are the result of several kinds of pollution and harmful effects to the environment and the atmosphere.

Solar thermal plants

They are so called the green-energy alternatives. They make use of the energy coming from the sun and are expected to be pollution-free. They are thought to be a great contribution in the present time of energy crisis.

Solar energy

But unfortunately, they don’t solely use the sun energy but a number of other chemicals are used in their working. This is making them cause pollution of several types. They also result in green house effect and thus in global warming.

Some of the solar thermal plants are designed that use natural gas or propane boilers other than the sun energy. This is used as a fuel to start up the units. It results in the production of the gases that cause the green house effect.

Photovoltaic Cell – How It Works?

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,


Photo voltaic cells are usually known as solar cells. These are frequently used in the applications of recently used electronic devices like satellites, calculators, and watches etc. However, these are used primarily in the space applications. Photo stands for light and voltaic corresponds to the electricity, so photovoltaic devices are used to produce electricity from the light. Hence, these are also commonly known as solar cells. Photovoltaic cells can be obtained in different sizes and shapes. Photovoltaic modules can be formed by joining different individual photovoltaic cells. The size of the photovoltaic array can be finding out by estimating the required output power and the accessible amount of light at the location.

Photo voltaic cells

Manufacturing materials for photo voltaic cells

Specific materials generally semiconductors are commonly used in fabrication of photovoltaic cells. Silicon is a semiconductor material which is mostly used for this purpose. Silicon is available in different forms like single crystal, poly crystalline and amorphous.  Thin films of some poly crystalline materials like Copper Indium Disengage, Cadmium Telluride etc are also used in the construction of photovoltaic cells.

Use of Silicon in Production of Photo voltaic Cells

When light falls on the photovoltaic cell, it absorbs the specific amount of light and reflects the remaining through photovoltaic cell. The absorbed light is only used to produce the electricity. Silicon has interesting chemical properties when existing in crystalline form. When a certain amount of light is absorbed in pure Silicon, a number of free electrons produce by breaking of the chemical bonds.

The power supplied from the utility is more costly than the renewable energy from solar or wind. Therefore the first step to take is to get rid of the current utility bills by installing solar cells for your home. When converting to solar power you have to be very cautious in your use of electric power. You can cut your energy requirements and in turn energy expenses by reducing the use of heating devices, increasing energy efficient lighting and appliances. Below are mentioned a few approaches to help you reduce your electricity bills.

Low Energy Consuming Home Interior

The peak load occurs due to the heating devices. With a simultaneous use of heating devices there is danger that the DC battery, supplied along the solar panels, can be depleted of charge very quickly; particularly in overcast and dark conditions. A few techniques to reduce this sort of use of electricity can help you reduce bills in case of utility supply or can attain a longer battery life from solar panels.

Energy Consuming Home Interior

Make sure you have effective insulation at your home. This is the most economical way of preserving heat of your home.  The windows and ceiling of your house are the main source of heat loss. The eaves should be insulated in order not to let the bulk heat escape in the form of warm air. The windows should be sheathed with curtains and blinds. The gaps on the outer side of the windows should be filled so that no cold air from outside can enter.
