How To Harness Solar Power In The Home

By: Adrian Fletcher

It seems that the cost of gas, electricity and oil to provide power to our homes continues to rise every year. This rise often seems to outstrip average inflation. We are often told that there are a number of legitimate reasons for this inflation. One that may not be so well publicized is that many utilities companies are privatized and have to run at a profit. Indeed, the management would not be doing their job if they did not turn a profit.

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.

You can run a house using the heat energy supplied by the Sun. The most typical application of thermal energy is to heat water. This can be used as hot water to use or heat the home. Solar thermal energy can also heat a swimming pool.

The principle behind this idea is that if you expose a flat metal plate to sunlight it will become hot. If the plate is painted black then more of the heat energy is absorbed. If you put insulation on the underside of the plate then less of the heat is lost back to the environment.

Once you have a hot plate you can allow water to come in contact with it and the result is heated water. This can be piped into the home to be used however it is needed. The solar heated water can also be connected to the standard water heater thus saving grid supplied energy on making the water hot.

Energy used to heat household water is one of the most expensive items on most utility bills. This could be reduced if a solar water heating system is installed.

Sunlight can also be used to create electricity. The technology that utilizes sunlight is known as photovoltaics (PV). A PV cell is made from a silicon based semi conductor. The PV cell reacts with sunlight to displace an electron. The flow of an electron from a negative to a positive terminal is the creation of electric current. By increasing the number of PV cells connected in series you can increase the voltage between the positive and negative terminals and the current of the electricity.

This is direct current (DC) that can be stored in a battery. It can also be converted to Alternating current with the aid of a power inverter. AC can be used to transport electricity or, more importantly, used to power the home.

The solar panels that you see on the roof of many houses are a number of PV cells connected together in a series or parallel configuration to increase the amount of electricity that can be produced.

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 stage in solar electricity is to go completely off grid. This means you cut off the utility company and rely on solar power solely. This may be scary for some people new to solar power but it is possible but more work. You will need storage devices for your electricity and backup systems should the Sun not shine. Many people have fuel powered generators or have wind or water power systems as backup.
