To preserve the environment we must seek to replace fossil energy use (petroleum, gas, coal, etc.) with renewable energy such as water, wind, solar, and others, including for electricity supply. Having solar power at home can be a great solution. This solar cell panels will convert sunlight into electrical energy. The next one will be stored in electric batteries to meet power needs at home. Basically, electricity generated by solar panels can be directly used or stored prior to the battery. The electrical current is generated by direct current electricity (DC) at 3.5 A. The resulting large voltage is 0.4-0.5V. Circuit design of solar panels can be assembled in series or parallel, to obtain the output voltages and currents are desired. To obtain an alternating current (AC) required additional equipment called an inverter.

In light of the sun’s energy is contained in the form of photons. When these photons on the surface of solar cell, electrons will be excited and cause the flow of electricity. This principle is known as the photoelectric principle. Solar cells can be excited because it is made of semiconductor material; that contain the element silicon. Silicon consists of two types of sensitive layer: a layer of negative (n-type) and a layer of positive (p-type). Now the solar electricity has developed into photovoltaic technology which is more sophisticated and eco-friendly.

But there are some things to consider when we decide to install solar power at home. Solar panels require sunlight to produce electricity, so solar panels should be placed where direct contact with sunlight without obstructed by objects or object. Your house roof is the best option. You should carefully calculate the cost and the design, so you will get the function as good as the house esthetics. Now, are you ready for your solar PV? I think you will.

Companies that generate solvent waste understand that the most cost effective and environmentally acceptable method of managing spent solvent is by not generating it in the first place. Source reduction techniques or minimizing the generation of spent solvent at the source as well as pollution prevention (P2) where toxic solvents are replaced with new non toxic solvents recovery should be investigated before examining the feasibility of recycling the commonly used toxic Solvent Recovery System in many businesses today. This fact sheet will only address issues concerning  the commercial recycling of toxic solvents due to their potential threat to human health and the environment.

Companies must consider many issues before pursuing solvent recycling as a waste management option. While some companies have chosen to install in-house solvent distillation units to recycle their own spent solvent, others have enlisted the services of a commercial solvent recycling company.

In house solvent distillation units minimize transportation, disposal and potential liability costs associated with off-site disposal. Sometimes, however, in-house recycling is not cost effective or consistent with existing facilities and labor skills, or it fails to produce solvent that can be reused by the facility. In these instances, a commercial Waste Recovery System may be preferred

Concern about the reliability of solar is a barrier to market growth; consumers believe they will be “buying” into a simpler lifestyle with solar that they are not ready for. solar energy systems are not often visible in our every day lives, in our neighborhoods or on our public buildings. We rarely see solar installations as we travel or on tV. the invisibility of solar technologies contributes to a sense that solar energy is not up to the task of powering our modern world.

we need better marketing to handle the situation. there are ways of marketing ideas, such as mailing lists and telemarketing lists service. it’s a way to make solar power become popular. List Giant specializes in and offers mailing lists and telemarketing lists. List Giant is a simple, online system to choose from tons of list demographics, run list counts, and download your desired mailing lists and telemarketing lists in minutes, 24 hours a day. it will help us to build a survey and determine the next step of solar marketing program.

However, solar programs can begin to address the issue of reliability by ensuring that solar is as visible as possible in their markets and is presented as a powerful source of energy, one that will help fuel and build a stronger economy.

Research also indicates that solar customers are much more comfortable with technology than “inerts”-those simply thinking about solar. As early adopters, existing solar customers are more at ease researching manufacturer and installer options than those who are more conservative about new technology.

so let start this task immediately.

Forty years ago, Harold Hay, 98, invented a simple, inexpensive way to heat and cool a home using the sun’s rays, but without the panels and wiring that come with conventional solar energy systems.

He’s been pushing for its adoption ever since, trying to find footing in each of the solar industry’s last three boom-and-bust cycles.

Yet, despite the merits of his pioneering technology, the energy establishment has shown only fleeting interest.

As Gore said, quoting Upton Sinclair “it is hard to get someone to understand something — if their salary depends upon not understanding it.”

When it comes to climate change, those who refuse to act are mostly those without imagination, or those whose financial interests support the status quo. Passive solar systems cost little or nothing to operate, and so represent a serious threat to the fossil fuel industry.

Hay’s system keeps a house between 65-75 degrees year-round with virtually no electricity. What’s the catch? It requires the house to be built from scratch, and built strong enough to hold a roof-sized pond of water. Still, to have no heating or cooling bills for the life of the home? Wow. [Click the story link at the top of the article for a video of this house and how the system works.]

Even if people didn’t want to have flat roofs, I see no reason why they couldn’t heavily insulate their home and locate the solar pond elsewhere on their property. Then they could use pumps and heat-exchangers to take advantage of the water’s thermal mass. Certainly this could be a great way to cool apartments and commercial buildings as well.

Cheap electricity, fuel oil, and natural gas have kept people using energy-hogging central furnaces and forced-air systems, generating countless gigatons of CO2 for decades. Solutions such as the Skytherm house are as simple and elegant as it gets and produce no CO2. Only two things stand between our current situation and a clean planet and better life: greed and inertia.

Carbon taxes will make the status quo prohibitive, and force many of these types of solutions. There are many details to be worked out, of course, but a better national energy policy can turn this sad situation of needless energy waste around. There’s no excuse anymore, it’s just common sense. It’s high time for solar energy to stop being a science project and get mainstreamed

Have you been thinking about changing your power source over to renewable energy? I have also listed some of the Solar Energy Cons. A person can’t sincerely arrive at an honest conclusion without acknowledging the advantages and minuses. You should check into every aspect of changing over before approaching to your ultimate conclusion.There are more Pros that are not listed here that may or will not be essential to you depending upon your stance regarding the environment.

* Solar energy is a renewable resource. It doesn’t induce pollution while you generate it.
* Sunlight, unlike fossil fuels is all over, all though it is not evenly dispensed throughout the world. Solar energy can be made anywhere, even when there are no local utility supplier, therefore you are able to have power in inaccessible areas.
* With the correct resources, the components necessary to construct a solar system can be bought or produced rather inexpensively
* The nicest matter about solar power is that it’s costless to all.
* The engineering in use to implement solar radiation as energy to get electricity, heat, and mechanical power currently exists
* Solar systems possess no moving elements and can last numerous years.
* You don’t require fuel to be delivered to your home, and you will never run out.
* Granted the correct data, it’s almost always possible to forecast the amount of power a solar energy system will give.
* The systems are silent and becoming more and more unnoticeable.
* You will be able to qualify for financial incentives from the government to assist with paying for your system and also get tax breaks while it is in use.
* Using solar energy means one less home burning fossil fuels, and reduces the creation of greenhouse gas.

Solar Energy Cons

I’ve listed the Cons for using Solar Energy as well. Although there aren’t many disadvantages, they should still be weighed in.

* If you don’t know where to get the components at a discount, the original costs can be kind of high.
* Solar panels can require a lot of space. That’s why the roof is the optimal location for them to be set up.
* You can’t generate solar energy at nighttime, so you need a way to store it. Batteries are a good energy storage choice. With the right information, you can purchase batteries for as low a $10 apiece or even free!
* Bad weather conditions can impact the amount of energy generated.

As you can see the Solar Energy Pros overbalance the Solar Energy Cons. If you are worried about the environment and you also acknowledge the income saving potential of using solar power, then this can be a good path for you to choose. I think that someday in our lifetime, solar power will become a more popular choice. By harnessing the power of sunshine, the Earth could change for the better one home at a time. Besides, our grandchildren will appreciate it.

Solar water heaters can be used to heat swimming pools and spas.

In a solar pool-heating system, the existing pool filtration system pumps pool water through the solar collector, and the collected heat is transferred directly to the pool water. Solar pool-heating collectors operate just slightly warmer than the surrounding air temperature and typically use inexpensive, unglazed, low-temperature collectors made from specially formulated plastic materials. Glazed (glass-covered) solar collectors are not typically used in pool-heating applications, except for indoor pools, hot tubs, or spas in colder climates. In some cases, unglazed copper or copper-aluminum solar collectors are used.

In residential applications where the goal is usually to extend the swimming season into spring and fall, heating a swimming pool with solar energy requires a solar collector that is 50% to 100% of the surface area of the pool. In general, adding more square footage lengthens the swimming season and allows owners to use the pool in colder weather. A pool cover or blanket significantly reduces heat loss in a cost-effective manner and helps maintain warm temperatures for long periods.

A solar pool-heating system costs between $2,000 and $10,000 to buy and install, depending on size. Costs run between $7 – $12 per square foot depending on system design and collection type. This provides a return on investment between 1.5 and 7 years, depending on the cost of the auxiliary energy being displaced.

Maintenance of solar pool-heating systems is minimal. The systems are pre-engineered and can be sized for any pool by simply adding additional solar panels to obtain an adequate solar collector area.

The only moving part on a solar pool-heating system is the diverting valve. This valve controls when the water circulates through the collector loop. If the collector temperature is sufficiently higher than the temperature of the water in the pool, water is diverted from the filter systems through the collector loop. The water bypasses the solar collectors during the night or cloudy periods. Some smaller systems are operated manually or with timers. Larger systems are operated by electronic sensors and controls.
