Learn More About Solar Panels

Welcome to Best Solar Pannels.com! Here you will find and locate various components of Solar Panels Perth. Our main objective is to guide you and enhance your understanding of Solar Panels and the benefit of Solar Energy. Enjoy!

Benefits of Solar Energy:

1. Solar energy is renewable. We never have to worry about running out of sunlight or using it all up. The sun is a consistent power source meaning it’s always going to be there every day.

2. Solar energy is environmentally friendly. Compared to fossil fuels which release greenhouses gases, carcinogens and carbon dioxide, solar cells don’t release anything into the air.

3.Solar panels are extremely reliable. There are no moving parts so you don’t have to worry about replacing anything. In fact, most people generate electricity for 1000s of hours with little or no maintenance.

4. Solar cells make no noise while collecting energy. There are no other renewable energy sources that are completely silent.

5. In the long run, solar electricity is cheaper than buying it from the power company. There is a start up cost, but then it starts paying for itself. Once you break even, everything after that is profit. Compare this to paying a monthly bill and getting no return on investment.

6. There is a huge variety of solar panel systems available. Some can cost tens of thousands of dollars, and some cost just a couple hundred. This means anyone can get into solar, there’s an entry point for just about everybody.

7. You’re not required to connect to the power grid. You can be completely self-sufficient and live off-the-grid. Imagine never paying another monthly bill or hook-up charge.

8. Sell excess electricity. If you build a large enough solar panel system, you can make your electric meter spin backwards! Most power companies will gladly buy or credit you for this excess electricity. Contact your local power companies for more details.

9. Government tax credits. Most governments will provide some kind of tax credit or incentive for people purchasing solar energy systems. On average, rebates usually cover 20-30% of the system cost. Contact your local representatives for more details.

10. Solar technology is constantly improving. Solar installations are increasing by an incredible 50% every year, most of which are small homemade systems. Learn how to make your own solar panels and use the benefits of solar energy to your advantage.

The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere.[1] Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth’s surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.[2]

Earth’s land surface, oceans and atmosphere absorb solar radiation, and this raises their temperature. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth’s surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones.[3] Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C.[4] By photosynthesis green plants convert solar energy into chemical energy, which produces food, wood and the biomass from which fossil fuels are derived.[5]

The total solar energy absorbed by Earth’s atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year.[6] In 2002, this was more energy in one hour than the world used in one year.[11][12] Photosynthesis captures approximately 3,000 EJ per year in biomass.[8] The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth’s non-renewable resources of coal, oil, natural gas, and mined uranium combined.[13]

From the table of resources it would appear that solar, wind or biomass would be sufficient to supply all of our energy needs, however, the increased use of biomass has had a negative effect on global warming and dramatically increased food prices by diverting forests and crops into biofuel production.[14] As intermittent resources, solar and wind raise other issues.

Solar energy can be harnessed in different levels around the world. Depending on a geographical location the closer to the equator the more “potential” solar energy is available.[15]
