Ever since man existed, sunlight was and will always be available. For several years now, a lot of people are complaining about the ever increasing electricity bills. Because of this, solar power systems became great alternatives through the years. Sunlight is readily available especially in countries where they get a lot of sunshine. With the yearly improvements in modern technology, solar power for homes is now more advanced.
With just a little amount of sunlight, you can already get more electricity. With only a few solar panels, you can generate the needed electricity for your home. Even if you live in a small house, you can install a solar panel.
Most of today’s homes are not properly oriented to get a lot of sunlight and this becomes a great problem. New solar power systems are more efficient and can generate quality electricity with less sunlight. The modern solar panels are installed at steeper angles but can still tolerate sunlight. So, if you’re home doesn’t have an ideal orientation, it would still be possible to generate solar power.
Solar panels are usually installed on top of the roof together with an effective rail system. The panels are able to slide at the best position to get sunlight. The system is also ideal just in case you want to expand later on.
Before you install solar panels, you need to determine the electricity requirements of your home. To calculate your monthly electrical consumption, you will need to go over your electrical bills and determine the average usage. After that, you can now pick the right system size. If this is your first time to use solar power, it would better to start with the simplest project you can find. Make room for expansion as well so that you can expand the system little by little especially if you have limited resources. Even if you use solar power as an alternative, you will surely be able to cut your bills by 80% in the coming months. Read the rest of this entry »

Why is efficient home insulation good for saving energy?
Almost half of your electric bill goes to regulating the temperature of your home. Thus if you want to save on your electric bills, the best place to start is your home’s insulation system.
Insulation is important to minimize or eliminate the heat exchange/loss inside your house. Good insulation keeps the interior warm during winter and cold during hot summer days. A well-insulated house allows your heating and cooling systems to effectively work as needed. Proper insulation can save as much as 10% of your monthly electric bill.
Meanwhile, if your house has leaks or if it has insufficient insulation, air will pass through; and heat exchange will occur on areas where insulation is inadequate. This results to heat loss. And because a house with leaks and insufficient insulation requires more power to regulate its temperature, energy consumption will likely increase.
Where to insulate?
Areas of the house including the switches, power outlets, plumbing fixtures, walls, windows, doors, ceilings, floors, basement, crawl spaces and attic should be properly insulated.
Insulation Tips
Make sure that you consider factors such as building design, budget and climate when selecting the R-values of the insulation materials. Use the proper R-values insulating materials for particular parts of the house.
Consider parts of your house such as the attic, floors, kitchen, bathroom, windows, walls, door and other parts where heat loss are more likely to happen. Use the required insulation materials on these parts to effectively control the temperature. Read the rest of this entry »

I was first introduced to solar energy in the movie, Race the Sun with James Belushi in the lead. It was a story about low- income and under achieving Hawaiian students encouraged by their teacher to join the Solar Car race. In the movie, a car shaped like a cockroach and covered with solar panels used the sun’s rays as an alternative energy source to run the car.
Solar energy is the light and the heat from the sun. Solar energy is free and its supplies are unlimited. There are no air and water pollution caused about by using solar energy. But there is still some impacts on the environment although indirect.
Photovoltaic cells used to convert sunlight into electricity uses silicon and also produce some waste materials. There are also large solar thermal farms and these farms can also be harmful to the environment and desert ecosystems if not properly managed.
Solar energy can be used on different aspects. Solar energy can be used in agriculture. Greenhouses (which is entirely different from greenhouse gas) convert solar light to heat to be maximized in enhancing the growth of plants and crops. Greenhouses has been around since the Roman times and modern greenhouses were built in Europe in 16th century. Greenhouses are still an important part of horticulture nowadays,
Daylight systems are also being used to maximize the energy released by the sun. It is used to provide interior illumination replacing the artificial lighting. Daylight systems include sawtooth roofs, light shelf, skylights, and light tube. Daylight systems when they are properly implemented can reduce lighting-related energy consumption by 25 percent.
Solar energy can also be developed into solar thermal technologies which can be used for water heating, space heating, space cooling and process heat generation. Solar energy can also be used to distill water and make saline or brackish water potable or drinkable. Read the rest of this entry »

The rise and drop in temperatures in the coming years, place intense pressures on consumers around the world as this means only one thing, more energy and fuel are needed to control the environment and make homes more comfortable.
Over the years, new technology has been invented to improve the manner of living – energy saving devices are not excluded. However new technology, as always, is a bit expensive at first. And the prices will go down after some time. But instead of waiting for a more affordable energy saving devices, let us apply our common sense today and do some effort in saving energy.
• Avoid “phantom” energy users.
Electrical appliances that are plugged in to sockets even when not in use consume energy. It is like a turning on the engine of your car and idling for a very long time. A single appliance that remains plugged in may not give a significant increase in your electric bill but letting every appliance on “standby” can be a real money spender. Make sure to pull the plugs of every appliance from their sockets whenever you don’t use them. Read the rest of this entry »

What is the cost for installing a solar power system? We all know that solar panels cost can take up to 50 – 60% of the total solar home cost people have to pay, however the cost of solar panels have been significantly reduced in 2009 and some experts expected the price to go down further this year. The number of solar residential has been increased in some States but some people are still reluctant to follow because they can’t figure out what is the real cost of solar power they have to pay. Many will ask questions like “How much does solar power cost for a 4800 square foot house?”
The answer to this question is actually depends on some factors:
- Where they live
- Total sun hours they get every day
- Total electricity they use every day
- Total solar electricity they want to make with the system
- Solar rebates and tax incentives (if applicable)
- Grid-tied or off grid (with solar batteries) option
We don’t need to 100% substitute the utility power with solar electricity because it really depends on how much money we are willing to spend on the solar electric system in our house. To help you calculate the solar price NREL has an online calculator set up for this purpose. Read the rest of this entry »
