How Much Can Solar Panels Save On Your Electricity Bill?

It is definitely helpful to be aware of the cost of the solar panels, but it is more important to know how much money solar panels can save for you.

Solar Power Adelaide recommend that you set up a solar power generating unit either through zero down payment loans or via a third party ownership model.

The renewable and eco-friendly solar energy helps you to save money in a variety of ways.

How Solar Panels Help You To Save Money

Basically, solar panels help you to save money in three ways:

1. Reduced Energy Costs

Installation of a solar power generating unit in your home helps you to cut down your dependence on energy from conventional sources. This offsets a part of the ever increasing electricity bills.

2. Tax Credits

Governments in countries around the world are willingly offering monetary incentives in order to motivate people to use solar energy. These incentives are often offered as tax credits. This results in the reduction of taxes to be paid by you.

3. Improved Home Value

The installation of solar panels in your home contributes a great deal to increasing its value.

How Much Money Can You Save By Using Solar Energy

Solar power helps you to dramatically cut down the cost of running your property. However, the factors that determine the amount of money you can save include the average energy consumption, usage pattern, feed-in tariff rate, the size of the system and where you live.

Average Energy Consumption

You can find out your average energy consumption per day in kWh by looking at your energy bills. Typically, a 5kW solar power system generates on average 18 kWh to 25 kWh per day based on its location. From this you can determine as to how much of your conventional energy consumption can be replaced with solar energy. Of course, you need to take into account the size of the system that you can install in your area.

Usage Pattern

The solar power system installed in your home will generate electricity during the daylight hours. You can feed the excess electricity that you generate back into the grid and you will earn credits for the same from your energy provider. This credit helps you to offset your energy bills.

Feed-in Tariff Rate

Typically, energy providers offer around 8 cents per kWh of solar energy that you supply to the grid. If it is possible, it is a good idea to shop around so that you get the best rates. The feed-in tariff can vary from one state to another.

Size Of Solar Power Generator

Larger systems generate more power than the smaller ones. As such, the size of the unit installed has an impact on the amount of money you can save.

Therefore, you must choose a sufficiently large system so as to cover not only your power usage, but also to maximize the return on investment and lessen the payback period.


The amount of power generated by the solar energy system is dependent on geographic location of your home. This in turn impacts the amount of money you can save. This is to say that a location where strong solar radiation is available a 2 kW system may be sufficient to generate as much power as a 3 kW system installed in place where the solar radiation received is less.

To summarise, the savings on energy charges are tremendous if you install a suitable solar power generating system in your home.

In addition, you will also benefit from the tax credits that you receive. As such, the annual savings can be in the range of thousands of dollars.

If you need more information, locally based solar power companies in your area can assist with specific benefits, savings and installation for your home.


Could Australia Build Their Own “Nevada Solar One” Power Station?

Currently, fossil fuels such as oil, coal and natural gas are being extensively used to produce electricity. These traditional sources of energy pose several challenges including security and environmental concerns and rising prices.

Government and businesses in countries around the world are, therefore, increasingly supporting the efforts to develop alternative sources of energy. Solar power generation is growing rapidly because of the several advantages it offers over other renewable sources.

What Is Neveda Solar One? – A Snapshot

Nevada Solar One is an environmentally friendly and renewable solar power plant built by Acciona Solar Power, which is a subsidiary that is partially owned by Acciona Energy, a Spanish conglomerate.

The utility-scale power plant commissioned in 2007 is spread over 400 acres of land and generates 64 MW of nominal power without any carbon emissions. In fact, the carbon dioxide emissions avoided is equivalent to emissions from 20,000 cars annually. The power plant serves as many as 14,000 homes every year.

As the world’s third largest concentrating solar power (CSP) plant and the first of its kind built in as many as 17 years, Nevada Solar One has scripted a renewable-energy success story. It has the potential even to compete with conventional power plants that use fossil fuels.

Nevada Solar One power plant makes use of a proprietary technology for tracking the location of the sun and concentrating the rays during hours of peak demand. There are 760 parabolic concentrators consisting of over 182,000 mirrors. They focus the rays of the sun on to as many as 18,240 receiver tubes. Fluids circulated through these tubes get heated to 735 degrees Fahrenheit and in turn transfer the heat to water to produce steam for driving a conventional turbine. The turbine is coupled to a generator to produce electricity.

Nevada Solar One created more than 800 jobs during the construction stage and about 30 permanent jobs in the operation stage. Sierra Pacific Resources and Nevada Power Company purchase all the power generated under long-term power purchase agreements.

Challenges Posed By CSP Systems in the Australian Context

Blistering sunshine, direct normal insolation in the 15 degrees to 35 degrees lattitude, is what makes it appealing for Australia to adopt the CSP technology.

By definition, top solar locations (remote deserts) do not match with the existing transmission and distribution infrastructure. It calls for installation of expensive transmission lines as Australian networks have been developed to deliver electricity from generators located beside gas, coal and hydro resources.

CSP generating systems work most efficiently only during the daylight hours. Therefore, it is not possible to rely upon them as primary sources of electrical power. Further, they cannot cater to peak demand hours.

CSP without storage systems is two times more expensive than large-scale photovoltaic systems. Heat storage systems are far more efficient compared to those that store electricity. However, even they may not be of great help if overcast conditions exist for several days.

The payback time for CSP systems is longer since they cannot generate electricity continuously.

CSP systems are extremely expensive. This one drawback outweighs all the benefits that they could bring. A report published by the Australian Solar Institute estimates the levelized energy cost for utility-scale solar thermal power as A$250/MWh.

Finally, it is not possible to use small dish/engine systems in backyards for powering homes since the cost of building a system with mirror alignment and Stirling engine is extremely high.


Since the 1980s, CSP systems have been in existence and technological advances have helped them to become more efficient. However, the fact that these systems can supply clean energy under appropriate conditions cannot be denied.
