Let’s start with the first source of renewable energy, solar power. Solar energy is free but most people are afraid of the cost of solar cells. A myth about solar cells is that they are expensive and not a feasible option for residential properties. Honestly, you can find service providers who will send you competitive quotes and a range of options based on your electricity consumption. You don’t need to invest USD100,000 when you need a solar panel that costs a thousand dollars.

In fact, if a thousand dollars is too expensive too, you can build your own. There are plenty of ‘do-it-yourself’ websites that will give you all the support you need. You can also consider purchasing, solar powered devices to help you avoid consuming electricity. For instance, you have solar powered cookers, solar powered heaters, air conditioners, etc.

Another source of energy, you must have heard about is ‘wind’. To harness wind energy, all you need to do is install wind turbines. If your home is close to the sea, offshore or at a high altitude you should consider this as a feasible option. It might seem expensive to install but you will save forty percent when compared to your electricity consumption. If you are a ‘go green’ advocate, you can have your neighbourhood switch to utilizing wind energy. A small wind farm (more than 10 windmills), can be an economical option and help you reduce a considerable amount on your electricity bill.

If you are lucky enough to have your home in the countryside or a farm, a very cheap alternative source of energy is biogas. Installing a bio gas plant is a one time investment, and you can switch your entire power consumption to this source of energy. Biogas produce methane gas that is created by fermentation of slurry (fermented house hold waste, animal waste, sewage, etc). Biogas is very popular alternative source of energy in developing countries and can be used globally.

There are plenty of renewable energy alternatives that are used today, and every effort is being made to reduce costs. If are flexible with the cost, you can always choose from bio fuel, geothermal energy, etc.

For those concerned about the environment, switching to a renewable source of energy can help you reduce your carbon footprint and eliminate your electricity bill.

One country that seems to be leading the way in the renewable energy revolution is the small island of Iceland. They have fully embraced geothermal energy and hydropower, and 82% of their primary energy consumption comes from renewable sources. The country has managed within one generation to ween itself from dependence on coal and oil to a system almost completely based on sustainable resources.

Another country leading the way to a greener planet is Sweden. Approximately 25% of Sweden’s energy consumption comes from biogas. Biogas is power that is created from sewage. In the Swedish city of Linkoping, all of the garbage trucks and buses run on biogas, and there’s even a biogas-powered train line! The government in Sweden has even converted confiscated alcohol into biofuel for green applications.

In 1973, the country of Denmark became independent of fossil fuel imports. Since that time, the country has continued to embrace green technologies, and now boasts the world’s first profitable offshore wind park. Over 20% of Denmark’s power consumption is derived from wind power, and that’s after exporting 90% of their wind production outside of the country. Denmark is also using solar power to run heating plants as well as other applications, and they are also working on using rapeseed oil as a new type of biofuel.

Costa Rica is one of many countries that is working to become the world’s first carbon-neutral country. They incorporate several green energies including geothermal, solar, wind and the burning of sugarcane waste. Their biggest source of clean energy is hydroelectricity, and more than 82% of Costa Rica’s energy is provided by its hydroelectric dams. A quarter of the nation of Costa Rica is also devoted to park preservation.

In the United States, the green revolution has faced opposition most notably from the giant oil companies. Americans are just now beginning to realize the very real threat that global warming poses, and many are now willing to look at alternative energy sources. In recent years, the U.S. has become the world’s fastest growing wind power market, and several major turbine manufacturing plants have either been opened or announced their intentions. Recently, the government has instituted tax credits, rebates and other programs to encourage Americans to purchase energy saving appliances, vehicles, etc. New homes and businesses are being built with environmentally friendly products and energy sources, and owners are receiving significant tax breaks for using green technologies.

There are many other countries implementing green technologies with the hope of saving the planet and making the world a better place – let’s hope they succeed.

1. the actual pump and
2. an energy source being powered by the sun, with a cable or wire connecting the two devices.

Solar powered pumps can be used to pump water for humans, livestock or plants. Since the need for water is greatest on sunny hot days the technology is an obvious choice for this application.

Pumping water using solar powered technology is simple, reliable, and requires almost no maintenance.

To date the greatest use for solar powered pumps has been in agriculture where the pumps can be used on remote farms and outback stations to supply water to livestock. The remoteness is the key thing here as powering the pump by any means other than solar would be costly and inefficient. In a like manner, solar powered pumps are used extensively in developing countries to pump water from wells and rivers to villages for domestic consumption and irrigation of crops.

A typical solar powered pumping system consists of an array of Photo Voltaic (PV) cells that powers an electric motor, which drives a pump. The water is often pumped from beneath the ground or from a stream into a storage tank that provides a gravity feed. No energy storage is needed for these systems (save from maybe a rechargeable back-up battery source). Solar powered pumping systems are a cost-effective alternative to windmills (particularly on still days) for remote area water supply.

The most inexpensive solar powered pumps cost less than $1,500 while the larger systems can run to over $20,000. Most PV water pumps rarely exceed 2 horsepower in size. A well installed quality PV water pumping systems can provide over 20 years of reliable and continuous service.

Whilst it has been the needs of developing countries and agriculture that has initially driven the demand for solar powered pump technology, a greater environmental consciousness around the world has seen many householders use solar powered pumps (rather than a less environmentally friendly internal combustion engine) to create solar powered waterfalls or solar powered fountains in a pond display.

A solar powered pond, powered directly from solar panels, will work whenever there is direct sunlight; the brighter the sun the stronger the flow. Some solar powered water fountains will include a remote solar panel with enough wire that allows for the solar panel to be placed well away from the fountain. Solar power offers a great alternative when convenient electrical installation is not possible – as is often the case with gardens.

Decorative additions to a solar powered pond display such as solar powered glowing frog lights and solar powered floating lily pad led lights can usually be purchased at the same place that you purchase your solar powered pump kit.

Solar photovoltaic energy converting sun light into electrical energy. The most commonly associated component are the photovoltaic panels or solar panels that you see mounted on roofs.

This article will be focusing on how photovoltaic solar power (solar panels) and systems work.

Why are solar photovoltaic panels always on the south (or north) side of the roof?
In order to get the maximum electrical output from photovoltaic panels they need to be oriented to solar south in the northern hemisphere and solar north in the southern hemisphere. Solar north and solar south are the same as magnetic or compass north or south. There is about a fifteen degree difference between them.

Most solar photovoltaic panels are set at home latitude plus fifteen degrees or home latitude minus fifteen degrees. Depending on if you want a summer or winter bias to the angle of the solar panels. In higher latitudinal areas it makes more sense to have the photovoltaic panels set on a winter bias, so that during the winter the solar panels still get enough sun light to produce electricity.

How does a photovoltaic cell produce electricity?
A solar panel consists of a collection of photovoltaic cells. Each photovoltaic cell is made up of silicon wafer. Silicon in its pure state is a poor electrical conductor. During the manufacturing process, an impurity is added to the silicon so that when the photons (light) strikes the wafer electrons are released and create electrical current.

The type of electrical current produced by a solar panel is a low voltage direct current, or DC, typically in the range of six to twenty four volts. Photovoltaic panels have a nominal output voltage of 12 volts and an effective operating voltage of 17 or more volts.

A solar panel’s electrical output is affected by several factors. They are angle of the photovoltaic panels to the sun, time of day, time of the year and weather conditions. Solar photovoltaic panels produce more electricity during the middle of the day when the sun is directly overhead compared to the early morning and late evening when the sun light is striking the solar panel at a shallow angle.

Components of a residential solar power system
A residential solar power system consists of four components are: photovoltaic panels, charging controller, battery pack and an inverter. The photovoltaic panels convert sun light into electricity. The electricity is sent to the charging controller who keeps the battery pack fully charged, but not over charged. The battery pack sends the electricity to the inverter who converts the DC voltage to household AC at 120 volts and 60 hertz.

Photovoltaic panel
The output of a solar panel is stated in watts. The wattage is stated is typically for peak sun hours. Since the amount of sun light varies through the course of a day, to level out the variations the peak sun hours has been adopted by most manufactures to help installers and customer’s compare different solar panel models.

Suppose a solar panel is rated for 100 watts and an average of six peak sun hours is available per day. Then the solar panel would produce 100 watts * 6 peak hours = 600 watt hours of electricity or 0.6 kilo watt hours (KWh).

Charging controller
Charging controller or charge regulator controls the charging of the battery pack. It continually monitors the battery pack’s charge state. If the batteries are low, it will send electricity from the solar panels to the batteries. It also prevents over charging of the battery pack.

Don’t allow someone to convince you that a charging controller is not really required. Directly connecting the photovoltaic panels to the battery pack can permanently damage the batteries and possibly cause them to explode.

Battery pack
The battery pack’s purpose is to store electricity generated by the solar panels during the day and then at night or during extremely cloudy days provide electricity to the inverter.

The battery pack typically consists of lead acid batteries. Lead acid batteries are relatively inexpensive and readily available. There are many different types, sizes and capacities of batteries available. The most popular are gel cell and AGM deep cycle batteries because they are maintenance free and last a lot longer than wet cell lead acid batteries.

The most important thing to remember about the batteries is that the need to be deep cycle. Deep cycle batteries are designed to be discharged then recharged hundreds if not thousands of times. A deep cycle battery is designed to discharged to nearly empty, but not completely and then be slowly recharged over time. A common mistake for home owners is to think that they can use automotive batteries instead of deep cycle batteries. Car batteries are shallow cycle batteries. They are designed to discharge a lot of current quickly and then be immediately recharged.

Inverter
An inverter converts the DC electricity stored in the battery pack into household 120V AC. Almost everything in your home is powered by 120V electricity. Things like table lamps, freezer, lights, motors, dishwasher, and so on.

There are two main types of inverters sine wave and modified sine wave. The power company provides electricity as a sine wave. The electricity’s charge value goes smoothly from positive 120V to 0V to negative 120V and then back up to 0V and finally up to positive 120V. Then the cycle begins all over again. The time it takes to go through the entire cycle is one second.

Modified sine wave is also known as a square wave. Here the electricity’s charge value goes from positive 120V to negative -120 volts in effectively zero seconds.

Most household devices will function on a modified sine wave power. Light bulbs and motors will work, just not quite as efficiently as they would on sine wave electricity. However, there are some electronic devices that will not work on square wave electricity. It will be necessary to check with the manufacture to determine if the device will work on square wave electricity.

Now you have a basic understanding of solar power how it works to power your home. Now you have enough information about how solar power works to determine if it is a technology that you would want to invest in for your house.

Advantages of Solar Power
Solar power is a renewable source generated from the sun, meaning that the solar energy source is never going to finish. So, we do not need to worry about we may jeopardy of the energy source if you over use it.

Solar power is environmental friendly energy source. Unlike oil, the use of solar energy will never causes green house effects or emits carcinogens into the air and causes the air pollution.

The sun is FREE. Unlike the traditional energy source which you need to pay more if you use more, there is not limit on how much you can use the energy generated from solar power, and you do not need to think of the electricity cost when you use a solar-powered energy generator, because the sun is FOC (Free of Charge).

Little maintenance cost on solar power system. Solar cells can last for a lifetime and because there are no moving parts, it needs very little maintenance. You do not really need to allocate significant budget for it maintenance cost.

Disadvantages of Solar Power
The key stopping factor that makes most of people who are interested to install solar power system is the total cost is expensive. A solar power system that provides enough energy to power an average sized home can cost anywhere from $6,000 to $20,000. Seeing the potential market demand on solar power system, the industries with continue research efforts are trying to reduce the material costs. Moreover, there are many simple-to-follow DIY instruction manuals had been made published to teach people how to build their own solar power system using cheap materials which can be found at local market.

The solar power can be generated without sunlight, which means the power cannot be created at night, during rain and winter season when sun is hiding behind the cloud. This had been one of key discouragement of using solar power as the alternative power solution.

If you build the solar panel at the roof of your home, it becomes part of the house. You may need to sell it together with your house if you decide to move to a new home. And you need to reinstall the solar power system at your new home.

Summary
You should clearly understand of both the advantages and the disadvantages of solar power system before you go ahead to convert your home to be solar-powered so that you can really benefited from the advantages of solar power while handling the disadvantages of solar power to minimize the impacts.

What do you get when you mix chocolate and wine? In the case of Clean Solar, Inc., you get solar. Silicon Valley Entrepreneur, Randy Zechman, is the founder of City Chocolate Fountains (the largest chocolate fountain rental company in the United States). Jeff Ritchey is a San Jose native and wine guru. He is a wine consultant for Pichetti Winery, San Saba winery, and has two of his own labeled wines. Together, they are the co-founders of Clean Solar, a Silicon Valley solar installer and integrator.

Randy Zechman will readily admit that he is a serial entrepreneur. Just over a year ago, with two successful businesses in his portfolio: City Chocolate Fountains and World 2 Do, Inc., Zechman was ready for a new challenge. Zechman and a friend of eight years, Jeff Ritchey, an award-winning winemaker, regularly attended a monthly Bay Area speaker series with a group of friends. After every speaker they would end up at a local restaurant debating the subject matter of that night’s speech, global warming and the health of the earth were often the center of those debates, which resulted in them seeing Al Gore speak at the State of the Valley conference in early 2007.

After seeing Al Gore speak on solutions for protecting our planet, Zechman began to research the solar power industry. Ritchey, while continuing to grow his label, Sensorium Wines, was also showing increased interest in the green movement, realizing that green technology was an ideal fit with his knowledge in geology, winemaking and construction.

Zechman knew that the scientific and construction skill set that Ritchey could bring to the table would be the perfect compliment to his business and marketing skills, which led him to approach Ritchey about starting a solar power company.

Zechman and Ritchey met weekly for 6 months, discussing the in and outs of the business and making sure that their ambitions would not get in the way of their friendship. “We had a heart to heart regarding our friendship versus business. We both believed we could manage both and that our friendship would not get in the way.” says Zechman.

“We’ve been friends for eight years and never thought about getting into business with each other, but this presented the right opportunity. With the market timing, our passion for doing something good, Randy’s sales and marketing experience and my technical and construction abilities, we figured it was a natural fit.” says Ritchey.

Clean Solar Inc. quickly became a reality and is now the Bay Area’s leading solar installation company. The fuel for their business growth is in the form of state rebates through the 10 year, $3.4 billion California Solar Initiative. While silicon is still in short supply, the rebates offer customers a chance to significantly lower the installation cost of a solar power system. Zechman and Ritchey are committed to staying ahead of the curve and being early adopters of new solar technology as it comes on line. “We want the Clean Solar team to stay abreast of the latest advancements in technology, maintain certifications, and educate ourselves in order to provide our customers with the knowledge they need as a solar owner.” says Zechman.
