Climate change and escalating energy costs have driven many people to consider using solar energy. Solar energy can be a viable way to provide much of your hot water, central heating or pool heating requirements for your home. Solar energy can also supplement your home’s lighting and other electricity needs.
The sun is an unlimited source of free and clean energy. The quest to harness this energy began many years ago. Solar energy has become a viable alternative to provide power for your home. The sun’s energy consists of heat and light. Both are used as a source of free energy.
The sun’s heating or thermal power is commonly used in sunny climates to supplement the hot water requirements of many homes. Thermal panels are mounted on the roof of your home. Water is circulated through a series of pipes and stored in a tank ready for use. These are very effective in sunny climates but have even been used with some success in climates with few sunshine hours.
Photovoltaic panels transform the sun’s light directly into electric current. This electricity can be used to provide lighting for your home or to provide power for your home appliances. Surplus energy produced during daylight more…
WHY CHOSE HOME SOLAR ENERGY.
The sun is down and suddenly everything just went to black, another power outage. “Where’s the flashlight?” Oh no, the batteries are dead. Can’t find the candles or the matches? What about the food in the refrigerator if the power is out for several days … or weeks?
While a generator will work to help cover some of your home’s needs, solar energy will provide for more of your needs and do so more efficiently. Some years ago, this area was hit by a severe winter ice storm that took out the power to millions of homes. That power was not restored for weeks and in some cases two months. We had energy - solar energy that provided power to our 110 requirements.
Residential solar panels create the energy, which is stored in a series of batteries. This energy is DC and requires a converter to AC for home use. A small system of solar panels to create this energy can run all of the 110 needs for almost 18 hours of the day or longer. Larger systems of panels can provide a full 24 hours.
When the need for the solar energy is not an emergency situation, the more…
My experiences with solar power outline some of the main disadvantages of this type of energy. I am a true advocate of alternative energy sources and will try anything to do my part towards preserving the environment. My experiences with solar power have not changed my views and will not prevent me from trying other methods but the world needs to understand that there is a price to pay what ever you do. In this article I have outline my own experiences of using solar power rather than looking at global disadvantages.
I have a solar powered hot water system which is becoming very hard to maintain. I live in an area which receives a lot of rain. This rain is hard water with above average calcium deposits. This leaves a white deposit over the actual solar panel. When the panel becomes crusted up there is not enough energy to heat the water. I’m now getting too old to climb on the roof to give it a wipe before it gets to bad. I have to pay someone quite regularly to sort it out for me. It costs me nearly $100 a month to keep this up. The electricity company does more…
Solar technologies use the sun’s energy and light to provide heat , light, hot water, electricity, and even cooling, for homes, businesses and industry.
Photovoltaic solar cells which directly convert sunlight in to electricity, are made up of semiconducting materials. The simplest cells power watches and calculators and the like, while more complex systems can light houses and provide power to the electric grid.
Building designed for passive solar and daylighting incorporate design features such as large south- facing windows and building materials that absorb and slowly release the sun’s heat. No mechanical means are employed in passive solar heating. Incorporating passive solar designs can reduce heating bills as much as 50 per cent. Passive solar designs can also include natural ventilation for cooling.
Concentrating solar power technologies use reflective materials such as mirrors to concentrate the sun’s energy. This concentrated heat energy is then converted in to electricity.
Solar hot water heaters use the sun to heat either water or a heat transfer fluid in collectors. A typical system will reduce the need for conventional water heating by about two thirds. High temperature solar water heaters can provide energy- efficient water and more…
I have no doubt that solar energy will reduce our dependence on oil. We have only recently begun taking our first real steps toward using solar energy as a resource. As a supporter I mean no disrespect, but I feel that up to this point most efforts to use solar energy have been little more than novelties. Still, what we’ve learned through the very limited applications of the last 20 years is that these novelty’ installations actually work. When oil was relatively cheap and seemingly endless, there was little incentive to invest in developing the technology; but today you don’t have to be a green crusader to understand that oil is not unlimited, and that the less emissions we put into the atmosphere, the better off we’ll be. The world is changing and now we are able to develop better solutions.
Twenty five years ago my aunt installed a solar hot water system on the roof of her suburban New York home. The system was to provide a savings in the area of 30 to 60% on her hot water costs, depending upon the season. Today, she is replacing the old panels with more…
The best reason to choose solar energy is that it is a free renewable source of power. Installing a home solar energy system now will save a lot of money on household energy bills in future. Switching to solar energy also reduces the output of carbon dioxide, year on year, so it is a great way to be eco-friendly. The more people choose a green lifestyle, the better it is for the environment.
A solar energy system will effectively cut down on the high cost of buying other forms of energy, even if it is only used to heat the water for a family home. Solar energy is an extremely efficient way to heat water. A good solar powered hot water system can provide all the hot water required by an average family.
The amount of money saved by using solar panels depends on where the house is located and the hours of sunlight on an average day. It will also depend on the size of house and how much energy is required for heating, lighting and for using electrical equipment.
Residential solar panels will work in almost any climate. They do not need constant sunlight to be efficient. Tilting the panels at more…
Living in Israel in the 1960’s most apartment blocks had an array of solar panels on their roofs to provide for the majority of each household’s hot water requirement. Over fifty years ago solar heating systems were in place to provide for the bulk of domestic hot water. More than 40 years later, solar panels to provide hot water are becoming popular in South Africa.
The popularity of solar energy in South Africa is partly a result of a power generating crisis in the country. The electricity supplier no longer has the capacity to supply all of the country’s electricity supply needs, and is offering subsidies to households willing to invest in solar panels. Solar panels used to provide hot water are using the sun’s thermal energy - it’s ability to provide heat.
Another technology being rapidly deployed are solar panels to provide energy to power traffic lights. This technology uses light energy or photovoltaic (PV) energy. Light is converted into electricity using semiconductor technology. Electricity produced can be used immediately or stored using batteries. These units are now becoming quite advanced, and are able to provide energy even under overcast conditions. Units are now becoming available that can provide most more…
The Purpose of Life; 11/9/08
In our recent economic crises, we’ve come to realize that as a nation, we the people are vulnerable to the decisions and directions of a handful of politicians. We also just united as a country and elected Barack Obama to lead our nation out of the foreign, domestic and economic situations. We have been drained financially by the worldwide price gouging and greedy backroom deals that have brought our country to its knees. The wars in Iraq and Afghanistan alone are a constant $10B draw every month. Where does that money get replaced from?
Instead of using $700B to bail out a failed system, help with the foreclosure crises and give immediate assitance by delaying motions until every home affected can be reviewed for individual remedies. We then unite to convert our country’s fuel system to compressed natural gas just as described in The Pickens Plan. This would create jobs nationwide between manufacturing the neccessary parts to convert, to auto parts distribution, to the auto repair shops, as well as the big 3 domestic auto makers, converting their fuel systems. Perhaps a joint venture between the three to lessen the initial onset as one instead of as more…
From the summer of 1999 till the summer of 2000 I worked as a maintenance mechanic in a small kibbutz in Israel. Most of my time that summer was spent unfreezing air conditioners and fixing the solar collectors that were used to heat the water for the hotel, the houses of the inhabitants and the various bungalows the hotel rented out.
We had three different system which essentially all worked the same. The sun heated pipes on the roof to near boiling, some with the help of parabolic mirrors others by using thin black tubes and the heating caused the water to circulate, the hottest water filling the boilers for the showers and the coldest water rising to be reheated.
Temperatures reached, in this very old system, were very high and I scalded myself repeatedly trying to repair the hoses that kept exploding because of overdue buildup of steam. I tried desperately to find the right valves for the system, but was left to come up with makeshift solutions, because of budget restraints.
Despite this, from early March till late October, the sun was all that was needed to supply hot water for the showers in the entire village. I both hated more…
Solar energy has many more uses than powering our calculators, and is becoming an increasingly popular option for those choosing renewable energy sources on small or large scales.
One of the easiest home applications for solar power is water heating. For solar water heating, a panel is installed on the roof of the house, which collects and transfers solar energy in the form of heat to a specially installed water tank in the house. The solar water tank is attached in tandem with the conventional water heater, so that if the sun has been shining, the solar water passes straight through to the shower. If however, it’s been cloudy, and the solar water isn’t hot enough, then the conventional water heater can supplement the heating.
The benefits of solar water heating are many, but topping the list are affordability (basic units can be bought that only operate in above-freezing temperatures), and ease of installation, as no changes need to be made to the home’s grid connection. Moreover, these units can supply upwards of one half of a family’s hot water needs.
For people wanting more extensive solar coverage, photovoltaic (PV) cells, and roof tiles are becoming widely more…
