Solar energy for residential houses is nothing new. It has just been relegated to the background in lieu of rising cost of real estate; newer more advanced building materials, design and the limitation of resources.

Since man started building homes, sunlight played a major influence in the design. In fact, even in the more advanced urban planning method of the Ancient Chinese and Greeks, the orientation of the buildings is as much as possible directed towards where it could capture the most sunlight.

The ancients might not be as intellectually sophisticated then to use catch phrases as passive solar and thermal mass but when they build, they were building in compact proportion, employing overhangs, producing insulation and building in manners that direct the airflow within the structure and producing well lit, well ventilated spaces using the relative position of the sun to the orientation of their structures.

Lately, as the conventional sources of energy became more expensive, homeowners were once again turning to the sun for energy requirements.

Harnessing the power of the sun’s ray to create energy to power our house is very appealing. But the question is, “Is everything about solar energy good?”

Looking at the current price of fossil fuel-based electricity, it is quite impractical to convert into solar energy system. However, with the growing concern on the state of the earth, there is really a need to find other means of energy aside from what power plants are using right now. Where do you place yourself?

Whether you are an advocate of clean energy or simply care about where your finances go, looking at the pros and cons of residential solar energy system will help you decide on whether to convert or not.

Pros

Solar energy is free. Did you know that the earth absorbs 174 pettawatts of solar radiation? This means that we have more than enough source of free energy to power every house in the world. Unfortunately, most of our energy is still drawn from oil, gas and coal. But in recent years, there is a steady increase of demand for alternative and renewable energy like solar power. It is estimated that the demand for alternative sources of energy will increase by 53% between 1999 and 2020. Read the rest of this entry »

Solar energy is free but the tools that will enable you to harness this free energy are not.  If you are planning to install a solar energy system right at your home and would like to know how much it would cost, there are 3 things you need to consider:

First, the cost depends on how much energy your household requires. More energy you require means more solar panels and higher cost of installation. The good thing is, the technology to harness the power of the sun is relatively cheaper than it was several years ago.

Second, the government is offering a rebate to those who will switch to alternative form of energy. That means, the government will shoulder a portion of the total cost of the system.

Third, you can get tax credits when you switch to solar energy system. The amount of tax rebate depends from state to state but the range can go from $1000 to $2000. Read the rest of this entry »

With energy sources depleting at a rate faster than they are being built, it is only wise that we use the abundant energy available for free – the solar energy. Apart from the easy availability, solar energy helps control environmental pollution. Most of us shy away from installing solar power solutions at home thinking them to be expensive and cumbersome. You will, however, be surprised to know how easy it is to employ these power solutions. Moreover, these will help cut down your power bills. Finally, you will be delighted to know tat you are doing your bit to save power for the future generations.

This article will explore the various solar power options available for home use.

Solar cooker: A solar cooker is a cooking utensil that uses absolutely no fuel for cooking. You can cook food for up to five people in the small box. If you are thinking that using a solar cooker will reduce your chances of spreading up a varied platter on the dining table, you will be surprised to know that you can not only boil food items in the cooker but also roast and bake! The only limitation with the solar cooker is the time it takes to cook. However, given the free source of energy it uses, this is a great option for cutting down those sky-rocketing bills and saving some power. Read the rest of this entry »

The earth receives more energy from the sun in one hour than the power requirement of the world for the whole year. Solar energy is free, renewable, clean and sustainable. We know how to harness it and we know where to use it best. Below are the different uses of solar energy.

Grid-Tied Residential Homes

Solar energy can be used hand in hand with your current electricity provider. This is ideal to those who live in places where sunlight does not shine year round, to those who live in areas where electricity is cheap and to those who just want to use solar energy as a backup to their existing source of power. The idea is that if you have 2 sources of power, you can get uninterrupted power supply all the time. Read the rest of this entry »

All cars are powered by gas. But with the volatility of crude oil prices and because it is not a renewable, something must be done before it is too late. Given that solar energy, a green energy source is used to power a community, you can also do this on a small scale by using the same principles to build your own car.

But what do you need to make this work? A lot of things but the two most important are the solar array and the batteries.

The solar array is vital because this is what’s used to collect the sun’s rays and then converts this into electrical energy. There are two types to choose from in the market namely the prefabricated type and the individual kind which you set up yourself.

If you are looking for branded parts, check out either Siemens or ASE Americas that sell terrestrial grade cells and the space grade cells. The lower end model which can produce a significant amount of power is the terrestrial grade version. Read the rest of this entry »

The earth receives more than enough energy from the sun in an hour to supply the world’s energy requirement for the whole year. Unfortunately, only a tiny portion of it is harnessed and the world still relies on power plants that burn fossil fuels. The good thing, though, is that there is a constant increase in demand for solar energy; and over the years of continuous development, solar panels are much cheaper today.

During peak hours, the maximum power density that the sun can give is about 1kW per square meter. In other words, one square meter of solar panel can produce as much as 100 GWh (gigawatt hours) of electricity in one year. That is enough to power 50,000 houses.

If a solar power plant is built on 1% of the total land area of the Sahara desert, it will satisfy the world’s energy requirement. The efficiency of solar panels depends on several factors such as pollution, clouds, temperature and atmospheric humidity. Read the rest of this entry »

The day may not be far off when the use of solar energy becomes a norm. There is now a deep conviction among experts that given a few years time, solar power will be in high demand that the cost will go down, inexpensive enough to undercut the prices of oil-generated electricity.

Previous predictions that it will still happen in a decade may no longer be true. The anger generated by the recent prices in oil and its vulnerability to market forces and other events may have already been enough to polarized people, governments and scientific communities into seriously considering a reliable alternative energy source.

You can not get a source more reliable than the sun. Even today homes that uses its power does not only benefit from the silent, energy generating, inexhaustible power of the sun, it also spikes up the prices of their homes. Those that have solar powered homes are even reimbursed for the surplus power that they supply to the power grid. Read the rest of this entry »
