As for collecting solar energy heat instead of electrical energy it has its own challenges with liquid heat transferences and using a liquid that won’t freeze in winter.  The collection of heat energy for use in home heating is more cost effective than electrical collection for the moment.  But as time progresses technological advancements in solar cell designs verses efficiencies should prevail.  We are at a time in the evolution of solar energy that is similar to what the computer age went through over about 30 years.  From very basic computers that were large, bulky, and costly, to very powerful computers, compact and affordable.

Solar energy is of course reliant on the sun.  This fact alone means the source is not going to disappear any time soon.  It can be concluded that solar energy is very reliable as a source to choose to capture, unlike oil or other forms of depleting sources.  Solar capturing systems are also fairly reliable. In particular the electrical solar cell has an indefinite life span because it is a semiconductor. Presently the solar cell of today is about 14 % efficient.  This efficiency will rise over time and be the main area that will bring down the cost of putting a system together.  So far the economy of scale to produce these cells is beginning to have a greater impact by bringing down the price of a solar panel from over 50 dollars per watt to 6 dollars per watt.

Ontario Feed In Tariff | Solar Power Installations

With government help some lucky people in various countries like Germany, Canada, and the United States are reaping the benefits of solar power installation due to incentives called microfit for smaller feed in tariff, which means feeding electricity into the grid.


Green Energy | Solar Power Installations

The Ontario Ministry of Agriculture, Food and Rural Affairs classify soils into seven groups in which the first is prime agricultural land while the seventh class has no agricultural capability. When we push the gas pedal of a car, we release the sunlight’s energy which was trapped in a plant millions of years ago by the process of photosynthesis.


Advantages Of Solar Energy | Solar Power Installations

Many people are reluctant to install solar energy or roofing solar panels, as they do not feel that it can compare to the energy that power companies are providing us. However those that have considered installing solar power or roofing solar panels have not gotten around to it yet. The problem that the world is currently facing is that the demand for power is increasing on a daily basis.


Solar Cells | Solar Power Installations

Stay away from used solar panels with heavy visible damage like built up moisture under the glass, big cracks on the glass, and damaged supports, unless it is something your know for a fact you can fix relatively cheap. The improvements are usually not enough to justify paying for a brand new solar panel, when you can get almost the same benefits from a refurbished solar panel.


12 Volt Solar | Solar Power Installations

As electric vehicles really begin to have an impact on our transportation system solar panels will become more and more important as a method to capture the sun’s energy. There is no doubt that twelve volt solar panels will remain an industry standard as the world continues to move into what I like to call the solar revolution.
