Residential Solar Power Solutions
It seems that fuel costs for the home rise above inflation each and every year. I’m not completely sure why this is the case. There have been many changes in the way utility companies are run in many countries. The biggest change is that many companies have become privatized. This means that they are responsible to their shareholders and their aim is to make a profit. This may explain why prices have been going up from a cynical perspective.
However the reason most often given for price rises is that the resources that create electricity are becoming scarce. Oil, natural gas and coal are finite resources and are becoming harder to find, harder to extract and harder to deliver to the consumer. Thus the consumer must cover the increased costs.
Within this context and partly because fossil fuels are thought to contribute to environmental change, people are keen to find alternatives to traditional energy resources. Solar power has been around for many years and is becoming a viable alternative to fossil fuels for generating power to the home. This article will cover how to run a house on solar power.
A popular way to run a home with solar power is to utilize the Sun’s thermal energy. Heat from the Sun can heat water. This can be used as hot water or the heat in the water can be used indirectly to provide warmth in the house.
The way this works is by exposing a metal surface to the Sun. The metal plate will absorb the heat and become hot. This process can be made more efficient if the metal surface is painted black and the areas that do not come into contact with the Sun are insulated to prevent the heat escaping.
When you allow water to come into contact with this hot plate the heat is transferred to the water. Thus you have hot water. This can be connected the plumbing of your home and used as a water source. In some cases it may not be hot enough for use and can still be connected to the standard water heater.
So a good solar water heating system can save you money on water heating costs which is often one of the more expensive items on a monthly utility bill.
We can also utilize sunlight to create electricity. This is a more recent development in solar power technology and is known as photovoltaics. Cells made of a silicon semi-conductor react to photons in sunlight. The reaction causes an electron to be thrown loose. The flow of electrons can be controlled using an electric field. This can create a current of electricity. The more photovoltaic cells that are connected the greater the voltage and current that can be produced.
This is direct current (DC) which can be stored in batteries or converted to alternating current (AC). Using an power inverter. AC is used in homes to power lights, and most appliances that plug into wall electrical sockets.
Solar panels that you may have seen on a few roofs around your neighborhood are the practical application of photovoltaics. One panel is a group of PV cells aligned in a parallel or series configuration to increase the output of electricity. The efficiency of solar panels has improved over the years. The costs to create and install a solar panel have also reduced over the years.
Most people will start using solar panels as part of their existing grid supplied electricity. They are essentially joint venturing with the utility company. All the solar electricity that they create is sent to the utility company and this is deducted from their total bill at the end of the quarter.
The advantages of this is that the utility company will install the system and the home is still attached to the grid as a safeguard should the sun not shine or a problem occurs with one of the components of the solar power system.
The next step is to go off the grid completely. This is more responsibility for the individual and more knowledge of the system is needed. They will also need a back up energy generation system should there be any problems.
