Energy From Solar Power


More and more people in the USA and worldwide are thinking about the possibility of installing an alternative energy system to power their homes. The most popular choices among home owners are solar power systems and wind energy systems. The preferred choice depends on your location: there is no point in installing a solar panel in a place where it won't get enough sunlight! However, for most locations, solar energy is a better choice (and it can always be complemented by a wind turbine, just in case!)
Energy From Solar Power produce electricity using so-called solar cells or photovoltaic cells, which convert the energy of sunlight to electric energy by the photovoltaic effect. These devices have been developing rapidly over the past few decades, and now solar power systems are much cheaper and more efficient than it was just ten years ago. From the economical viewpoint, it is certainly very feasible to install a residential power generator as a supplemental energy source to cut on electricity costs. Moreover, solar power may be even more economical for you, because many states and regions offer substantial incentives to consumers such as tax breaks or direct rebates.
Why choose solar electricity for your home? Besides obvious economical considerations, it has the following benefits:
Clean. It doesn't require burning fossil fuels and doesn't produce greenhouse gases.
Plentiful. The solar power is truly unlimited for any practical purposes. The amount of energy radiated by the Sun that reaches Earth each minute is more than the yearly energy consumption of the entire planet.
Easy to install and use. Solar panels don't require complex and expensive maintenance after they are installed.
Overall, installing your own home solar power system is definitely a great way to cut back on your electricity costs and reduce dependence on fossil fuels.



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
