My Energy Savings - Facts About Solar Energy

Friday, September 3rd, 2010

Facts about solar energy help people understand the efficiency of solar power for heating homes, charging batteries and other appliances like solar flagpole light, free energy for homemade aeroponics system or home hydroponics and so on. It is almost impossible to make a valid choice for home energy systems unless we know about the available options. The applications of solar energy are multiple around the house, although most people have only heard of water heating with photovoltaic cells. But did you know that you can heat your swimming pool, power attic fans, computers and small appliances with photo-voltaic cells?

Sunlight is efficient for charging batteries, this is one of the best known facts about solar energy. The demand for solar panels is presently higher than the offer, although production has increased over the last years. And there’s no mystery about it: not all geographical areas and climates are compatible with the use of photo-voltaic panels. It is more difficult to get enough solar energy for all the electric appliances when you live in a cold or temperate climate.

In terms of statistics, some interesting facts about solar energy indicate that water heating consumes most energy of all. It takes around 30% of the total energy to heat water. The solar system as such consists of one or more panels with photo-voltaic cells, an inverter, a battery, a charge controller, the support structure and the corresponding wiring. The government presently offers tax credits and rebates for anyone who buys and installs specific types of energy efficient home systems.

If you are interested in more facts and statistical data about solar energy, you will see that for sunny climates, a 1 kilowatt home solar system can produce approximately 1,600 kilowatt hours in a year. In cooler climates with about 2 hours of sunshine per day, the number of produced kilowatt hours ranges at about 750 yearly. Even for average systems, the coal consume and the level of CO2 emissions is drastically lowered.

The optimal number of solar panels into an average home solar system is between ten and twelve; the panels should be oriented towards the North for maximum exposure. Solar panels have very extensive warranties, up to 20 years in the majority of cases. Yet, the system as such has a lower warranty span of about 5 years. The energy storage capacity and features vary according to the model of the panels. Cells collect sun energy and store it in batteries, or sunlight can be reflected, absorbed or insulated.

Using Facts On Solar Energy

Facts about solar energy help you to understand how solar energy works and how you can save some dollars without having to run a high energy bill. Solar energy is a inexhaustible resource and of the oldest method of energy use that is available at nowadays. The significant fact about solar energy is that the sun s beams are so powerful that if we are to convert that into energy it would mean that Earth will never run out of energy for at least another 4.5 billion years according to scientists.  Sun never create any hazardous by-product which could harm the environment.

During the early 1950s solar energy was looked upon as an substitute to man made energy resources. Through much research it was found energy could be acquired at much cheaper source. With a constant figure of 20% - 25% demand growth year-by-year, the solar energy demand increases for last two decades. Solar energy is able to support household gadgets, lighting and water heaters. As of the moment, solar energy is more heavily priced but in the near future with the growth in scientific studies, it will bring down the prices and also increase its efficiency. By 2025, it is expected to generate 2.5% of the world energy demand through solar energy. Solar energy can be considered as the fastest growing technology.

There are some primary facts about solar energy that one needs to be acquainted to; solar energy is measured in kilowatt hours and 1 kilowatt=100 watts. One kilowatt hour is equal to the total of electrical energy which is required to burn 100 watt light bulb for roughly 10 hours. 866 kilowatt is the use by an average American household. The Residential Energy consumption Survey conducted in 2001 shows that an annual energy bill was around $2000.

A reduction in unit costs has contributed towards an increase in growth rates and thereby making it an critical energy resource. Since 2000, solar energy has been expanding at an incredible rate of 40% per annum. Solar energy  is moving at a progressive rate in the developing countries too as the consumption of fossil fuel has doubled over the years. When compared to solar energy which is infinite, fossil fuel reserves are lessening.  Setting up solar energy appliances is relatively easier in the more remote areas in comparison for setting up an expensive power grid structure. A disfavor of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas.
