Home solar power and DIY Photovoltaic Solar Panels

People can be attracted to solar power for different reasons. Most do want to make difference to green house emissions. Most people going to solar energy want to power their home in order to be independent from the utility pricing or 'dirty' electricity . Or they may want to have continuous service Many will adopt a DIY approach to home solar power.

Over the last two years electricity prices have risen in most capital cites and we are almost certain to face more rising electricity prices over and above the cost of inflation into the foreseeable future . Energy demand is projected to grow steadily over the next several decades, and supply will become more constrained (or expensive) as governments from all over start incorporating the cost of CO2 emissions into the cost of generation from fossil sources.

This will also act to drive solar panel prices down, as increased demand creates greater technology and greater economies of scale.

Hence solar is being seen as a solution . Two types of solar systems are effective in the typical average home:

Solar Hot Water - heats your water

A diy photovoltaic solar panels Power System creates electricity.

The PV solar panel is a panel designed to collect solar energy and convert it to electricity. PV converts the sun's energy to useable electrical energy using a series of cells on a solar panel. The energy converted is delivered by hard wiring to the home's power circuitry . PV is now being used to provide price-competitive, low greenhouse emission energy to homes and businesses across the country. The use of PV - photovoltaic technology is increasing. It has been used to power homes for many years, and with good reason. Sufficient sun falls on the USA to provide the nation's total energy needs . With a few solar panels the homeowner can capture some of this energy , and a diy photovoltaic solar panels project can be extraordinarily rewarding .

The starting point for a diy photovoltaic solar panels system is to gain an understanding of how much power you are currently using; how much power you will obtain from different alternate energy sources , and how much of a percentage of your needs they will supply. You will need to dig out your electricity bills for the last year. Work it out for an entire year and you can then determine the average usage on a true daily average. Add up the number of kilowatt-hours you have used over the year , and divide that number by 365. Now you've got your average usage in kilowatt-hours per day.

You can then start looking at hooking yoursolar system to the grid-connect systems that are available. You need to factor in your location and calculate how much electricity they can produce. These are based on calculators which each electricity supplier or provider will have on their website.

If, for example your dwelling is using an average of 20 kilowatt/hours per day, that means that a 2 kW system outputting an average of just under 10 kilowatt/hours per day would provide almost half your electricity needs. Note that these figures presume an optimum installation. Variations from true north in the southern hemispohere and true south in the norther hemisphere and from the optimum tilt angle will reduce the power output.

Solar power for homes is only fully efficient when every photovoltaic cell in every panel in your system is exposed to full sunlight. For diy photovoltaic solar panels for the home, note that even the smallest shade from a tree branch on one photovoltaic cell can dramatically decrease the efficiency of the overall system. The solar energy collected is converted to electricity through the PV process.
