The Truth About Solar Power

We have been using solar energy for years, from the calculators on our desks to the watches on our wrists. But there is a major difference between the solar energy that power these small devices and the kind of solar energy that can power our homes.
The sun is a free abundant energy source; it is sustainable and does not produce hazardous pollutions or emissions. Every 40 minutes, enough solar energy hits the surface of the earth, enough to power everything for a whole year. It seems that solar power is the solution to our energy needs. But in truth, it only accounts less than 1% of energy supply in countries employing solar power.
So what is the problem? If we have this abundant source of free energy, why can't we utilize it to its full potential?
Converting the sun's energy into electricity is complicated. Photovoltaic panels are installed up on the roof or on any flat surface. The sun hits the panels and generates electricity. An inverter changes it to AC (Alternating Current) the kind of power that is use in homes.
Although home solar installations on homes have tripled since the year 2002, its installations can be very expensive. At the website coolerplanet.com, there is a solar calculator. In here, you can type in your address, your average power consumption and see how much it cost to install a solar power system in your home. For example, a 2-bedroom, 2-bathroom house in California, the website's calculator estimates over $80,000 to install a solar power system and that is after 30% federal tax credit and local incentives. It is even more expensive depending on where you live, how many hours of sunlight hit the house and even the orientation and angle of the roof. With this, solar power is not viable for an average homeowner; conventional method is still providing the affordable energy.
But, after decades of false starts, solar power is once again a priority. A new study finds that solar power can grow up to 10% of a nation's power supply. And with huge amount of money allocated for research and development, the future for solar power is looking bright. Nowadays it is very obvious, cheap solar panel kits are readily available and is ready to be built to have a functional solar power system for homes. Most importantly, it is very affordable. It just costs a fraction of what was mentioned above.
Making solar panel guides includes all the things you need to know, like detailed instructions, a video guide that guides you visually in the construction, a calculator that enables you to compute how many solar panels and how large the area should be for it to power the entire house efficiently and safety precautions you are going to observe while you are building it.
We want our planet to restore to its natural condition. Let us help the earth by using renewable and clean energy. There is an alternative source of energy which is free and with unlimited resource, visit BuildYourOwnSolarPanels.org for more information. Let us care our planet and save it for future generation.
