Today's green guest blogger is Charlie Burrows with an article about one very big benefit of doing your part. It not only is good for the enviroment and conserving energy and resources, solar directly saves you money and in a lot of cases your invetment in solar can even give you immeadiate positive cash flow.
"Solar PV Systems: If they are good for the Earth and they save you money, why not?"
Solar energy. As soon as the phrase is uttered or mentioned you can guarantee there will be at least one person (at least where I live) that rolls their eyes or “tuts” it away as some magical myth that hippies and Green Peace and earth-friendly veterans have made up to stop us from using those nasty carbon dioxide emitting devices we all use. Well, admittedly it was probably worse a few years ago than it is now but the stigma still lingers around solar power and incredibly it is still not being taken seriously. As a fairly logical and straight forward thinking individual I am inclined to look at things with an icy cold clarity, pondering the ultimate question: How much will it cost and will it save me money?
The answer to the latter part of the question is yes of course it is going to save you money. No matter what you may think of “hippies” or Green Peace or anyone that favours solar panel technology (myself included), I think it`s safe to say we are not stupid and without logical thought. This technology was introduced as an alternative method for generating energy but in a more eco-friendly way. It has succeeded and not only that but it does save money in the long run. Like with anything, there is an initial output of cost but even this is not astronomical and the benefits easily outweigh installation costs. These include:
-
Electric bills being reduced (we all like this one)
-
You are reducing your Carbon footprint as your shiny new system is not emitting any harmful CO2 to the atmosphere. For a standard system it could save over 30 tonnes of CO2 during its lifespan. That is an enormous amount even as a general estimated figure.
-
If you sell your property you can command a higher price due to your existing installation.
-
Some figures show you can actually get a better rate of return by investing in a Solar PV system than by using a bank account or ISA.
-
You are not relying on a limited resource in order to run your system and sunlight will always be available.
The list could go on there really are that many positives to installing Solar Panel technology. The Feed in Tariff is ever changing it seems, with the Government assessing costs etc. but you can also make money by selling unused energy back to the grid if you have a surplus amount you don`t use.
Normally I am the first to be skeptical about new technology or anything that has an all-singing, all-dancing list of benefits but let`s face it, solar pv installers and various systems have been available for a while now and the gradual popularity of them can be seen across the country and indeed, across other countries but still this stigma persists of it being something that is “not real” or “not as good as they say it is”.
So again I ask, why shouldn`t we be investing in what is a clearly productive, cost-effective and eco-friendly scheme that saves money and contributes to the world we live in? It`s a no-brainer.

Amazing facts about solar panels
Solar panels are basically assembled by joining together solar or photovoltaic cells that capture the energy of the sun. It is through these photovoltaic cells that light energy gets converted into electricity with the help of an electrical device. Solar power is truly the fuel of the future as it is clean, green and also abundant, unlike the fossil fuels that we are consuming at an alarming rate! Meanwhile, here are some amazing facts about solar panels:
1. Solar panels are advantageous as they can bring electricity is even the most remote of places, where it is difficult to get electrical wiring done. The interiors of Australia would hugely benefit out of this as solar panels require minimum maintenance and only require a back-up generator and batteries to function.
2. Solar energy, despite having a promising future, is still quite expensive and requires a considerable amount of initial investment - although the long term benefits pay off those expenses.
3. Solar energy has been used since times immemorial, and a British scientist by the name of John Herschel had already invented his version of the solar cooker some two hundred years ago!
4. Albert Einstein won a Nobel Prize in 1921 for his experiments on photovoltaic power that included solar power.
5. If you make photovoltaic cells out of silicon found in one ton of sand, then it has the capacity to produce as much electricity as that produced by burning 500,000 tons of coal!
6. California gets abundant daylight and the capital city San Francisco can actually cater to all its daily electricity requirements by installing solar panels over all school and Government building rooftops alone!
7. Germany generates solar energy during the parts of the day when it is sunny and then it stores in batteries in order to consume it during cloudy days.
8. During the year 2009, ten thousand homes in the US disconnected themselves from the grid and used solar power for their electricity needs. These homes even managed to sell the excess.
Solar energy has a great potential and it is also becoming affordable these days, which has increased its popularity even more. With new and innovative technologies giving rise to sophisticated and efficient solar panels, there is a worldwide interest to exploit this renewable energy source. There are many parts of the world that are arid and receive maximum sunlight throughout the year, and therefore if solar panels are installed in such places, we might end up tapping solar energy in an optimal way! By installing solar panels in our homes at an individual level, not only do we adopt an eco-friendly way of generating electricity, but we also end up reducing the household expenditure towards electricity - which is an added benefit too!

The California Legislature recently passed several laws that will help clear a path for further renewable energy projects that will help keep the state at the forefront of renewable energy innovation.
Large-scale solar projects have been allowed to proceed without disturbing species or sensitive lands under Senate Bill 168. The bill provides solar developers incentives to locate projects on what is termed “impaired farmland,” or land that is no longer suitable for agriculture applications because it has either become non-productive or it has been contaminated.
The bill also grants developers of wind energy projects permission the “incidental” taking of endangered species as long as a conservation plan has been approved and is being implemented. Impacts to the California Condor and Golden Eagle, two fully protected species, have presented difficulties to wind developers.
The bill was supported by both environmental and agricultural groups, and its signing makes possible the Westlands Solar Park, which will be a 5-gigawatt solar plant to be built on 30,000 acres of farmland that has been deemed impaired. The project, when completed, will be the largest of its kind in the United States, and would supply enough energy to power almost the entire city of Los Angeles.
Senate Bill 267 allows a solar photovoltaic or wind farm to be granted exemption from a water consumption analysis if it takes no more than 75 acre/feet of water per year. This will aid in the implementation of solar energy systems because it will streamline the time and the cost it takes in order to receive permits for projects that have a low demand for water.
Senate Bill 226 will reduce the permitting time for solar projects that convert from solar thermal to PV or are located in urban infill lands.
Finally, the Renewable Energy Equity act, also known as Senate Bill 489, adds all small-scale renewable energy projects in California’s net metering program. The bill broadens the law beyond fuel cells, wind and solar to include biomass and biogas – including agricultural waste products such as nut shells and wine pumice – that makes these projects easier to connect to the power grid and to help the state meet the goals it has set for renewable energy production.

The first step in making the move to go to solar energy is, of course, making the commitment. The next step is to find a solar panel system that fits within your budget, and to make sure that you account for all of the other components of the system. Once you have done both, you are ready to plan your Menlo Park solar panel installation. This is a very involved step that requires a lot of special attention. Some of the things you need to do to complete this step include:
Identifying what size system your home needs
This is a fairly straightforward step, but it is fairly involved. First, look at your energy bills for the past 12 months and determine how much power you’ve used. The size of the system that is right for you depends on whether you want to eliminate your electric bill entirely, or you are simply looking to lower the bill. Next, take a close look at your roof in order to see how much space you will have available for the installation of the panels. At POCO Solar, we will not only be glad to help you determine the size of installation that is right for you, but the type of solar panel that is right for your needs as well.
Selecting the right equipment
Choosing the right type of solar panel you want for your Menlo Park solar panel installation involves taking into consideration several factors, including the budget you’re working with, the level of efficiency you’re looking for, and the amount of shade your home receives. You next need to determine the number of power inverters that you need. Power inverters convert a home’s DC power into AC power; each inverter can handle a certain amount of energy emitted by a certain number of solar panels. Next, you need to determine where you want to place the inverters and whether or not your roof will allow for expansion of your system in the future.
Deciding your budget
There are several financing options you will need to investigate, because a Menlo Park solar installation can run into the thousands. Even if you are fortunate enough not to need that financing, there are still advantages to leasing panels and buying them.
Deciding on the right installer for your solar power system
When it comes time to determining what company you believe is right for your Menlo Park solar panel installation, you should conduct some thorough research. Do an Internet search and look for positive reviews on the companies that are worthy of your consideration. Then, call those companies and ask to speak with customers who have had an installation similar to what you will need to you can ask them personally about their experience. This is a very, very important decision, so you have to be extremely careful in choosing a qualified installer.

When you decide to make the commitment to solar energy, it is obviously not one to take lightly. After you have made sure that you have accounted for all the components of your system, and made sure that your solar panel system will work with your budget, the next step is planning for your San Jose solar panel installation. This requires a great deal of attention, and here are some of the things you need to do.
Determine the right-sized system for your home
While this is a fairly involved step, it is one that is pretty straightforward. Take a look at your energy bills over the past year to determine the amount of energy that you have consumed. You then need to decide whether you want to simply reduce your energy bill or you want to eliminate it altogether, because the answer will determine the size of system that you need. Then, inspect your roof closely to determine how much space you have for the panel installation. A POCO Solar representative will help you determine the kind of solar panel that is right for you, and will also help you determine the size of installation that you need.
Choose the right equipment
A critical part of planning for your San Jose solar panel installation is selecting the correct type of solar panel for your needs, and there are several factors you must consider when making that determination. You need to consider your budget, the amount of shade received by your home, and the level of efficiency that you want. Next you need to determine how many power inverters you need for your installation. A power inverter converts the DC power of a home into AC power, and each inverter can handle a particular amount of energy that a certain number of solar panels emit. You then must decide where you want the inverters placed, and whether or not your roof has enough space to allow your system to expand at a later date.
Determine your budget
A San Jose solar panel installation can run into the thousands, so you will probably want to look into several financing options. However, even if you are not in need of financing, there are still advantages to both buying panels and leasing them that you should explore.
Choose the right installer
This is probably the most important component of planning for your San Jose solar panel installation. You need to do some detailed research; do an Internet search and look for installers that have positive reviews. Call those providers and ask for the contact information of customers who have provided those reviews so you can get detailed information on how their experience went. Preferably, you will talk to customers who had an installation similar to the one you are considering. Again, this is a crucial decision, so you need to take extreme care and make sure the installer you choose is qualified.

We are fortunate in Southern California to be able to have a progressive utility like Southern California Edison serving us. While you may have had your issues with the utility, like people across the country have with theirs at one time or another, there is no disputing the fact that SoCal Edison is an innovative provider that is constantly looking to diversify the means that they generate electricity through renewable and sustainable forms of energy. And they continue to invest millions in smart grid technologies that will benefit everyone in the long term.
The downside, of course, is all of that investment costs a great deal of money, and SoCal Edison is a profit-driven enterprise, obviously. So that cost gets passed down to customers and makes your electricity bill rise.
Next year will be no exception, as rates will rise in 2012. But if you are considering a solar power installation for your home, this could be good news for you. We talk to scores of people on a regular basis about the benefits of turning to solar, and many times we point to ever-increasing electricity costs. These costs tend to rise gradually over time; the current rate increase will, according to how much power you use, raise your bill somewhere between $3 and $10 a month. And SoCal Edison is not alone, as several other utilities will be raising rates as well, including San Diego Gas and Electric and Pacific Gas and Electric. It’s simple economics – as demand for a product goes up, so does its’ price.
When you make an investment in solar power, your monthly electric bills are either reduced significantly or eliminated entirely. As soon as you receive your first bill after your installation, you begin to see return on investment. And one that investment has been paid back, then you will see even more substantial savings. And when rates increase, as they soon will, those savings only get better.

A solar inverter converts electricity generated by your solar panels (this is direct current, or DC, power) into power that can be used in your home for your computer, television and other wired products (this is alternating current, or AC, power). A solar panel cannot create AC power on its own; it needs help in the form of an inverter.
How AC power differs from DC power
In AC power, the current moves both forward and backward along a wire. In DC power, the current flows in just one direction. There are some products, such as light bulbs, that can run on either AC or DC power. However, electricity networks in the U.S. were built to use AC because that form of power can easily travel over long distances.
Devices that use DC power
It is true that televisions, phones and computers use DC power, and have to convert AC power back to DC power. That is what is going on in the small black box attached to the power cord of your laptop. However since the U.S. grid is designed for AC power, the products we buy are obviously also designed to use AC power. When a solar panel creates DC power, the inverter converts it to AC power so that it is compatible with the gird. That power is then inverted back to DC by the power supply on your electronic devices. Many countries use DC networks, but because we are in the U.S. we have to have inverters.
The efficiency of DC to AC (and back again) conversion
Usually, inverters have about 95 percent efficiency, meaning the conversion of DC to AC results in only about a 5 percent loss of power. Converting from AC to DC, however, is less efficient and results in anywhere from a 10-40 percent power loss. This is the case whether you are getting your power from the grid or your solar power system. If the black box on your laptop power card is hot to the touch, that means the conversion from AC to DC is low in efficiency.
The different kinds of inverters
The typical home has a central inverter, a box that converts DC power to AC. Many homes have that box on a garage wall. There are newer kinds of inverter, called a “micro inverters,” that work independently from each other and are located under each solar panel. These inverters take longer to install and are more expensive.

It happens at the worst time. You neglect to charge your smartphone or your laptop computer, and it runs out of juice when you need it the most, and you have no access to an electrical outlet. However, that problem may eventually be a thing of the past, thanks to solar energy and work being done by researchers with the UCLA Henry Samueli School of Engineering and Applied Science.
According to a recent story that appeared on the Science Daily website (www.sciencedaily.com), the UCLA researchers have created a way for electronic devices to harvest and recycle energy. By equipping these devices’ liquid crystal display (LCD) screens with photovoltaic (PV) polarizers, they will be able to convert not only sunlight, but also ambient light and their own backlighting into electricity.
Just about every portable electronic device on the market today has some form of LCD display – it is found on tablet computers, laptops, monitors, smartphones and television screens. These LCDs consist of two polarized sheets of material that let a certain amount of backlight emitted by the device pass through. Between the two polarizers are located miniscule liquid crystal molecules. These crystals can be manipulated by small transistors to act as light valves, which let a certain amount of backlight escape.
But the UCLA team has developed a new kind of polarizer for LCDs, one that harvests energy. It is called a “polarizing organic photovoltaic,” and can work as a polarizer, a PV device and a sun-powered or ambient light PV panel simultaneously. Basically, according to the Science Daily article, the polarizers can act in the same fashion as typical solar cells, turning indoor or outdoor light into energy. For example, an iPhone user could conceivably charge his or her device via sunlight instead of a wall outlet.
According to the article, today’s LCD polarizers are extremely inefficient. A backlight can consume up to 90 percent of a device’s power, but up to 75 percent of that light is lost through the polarizers. A PV LCD, however, could recoup much of that lost energy. The UCLA team is working to increase the efficiency of polarizing organic photovoltaics and hopes to work with device manufacturers to integrate the technology into retail products.

When considering Aptos home solar power, one of the first questions might be, “Will this work in my home?” There are also other considerations, such as the orientation of your home toward the sun and overhanging trees. But active and passive solar power systems can work under a wide range of conditions, with photovoltaic systems being especially more flexible than most people may think. There are still, however, quite a few factors when deciding if Aptos home solar power is right for you. Here are a few of them.
- Closeness to the power grid – If your home is more than a half-mile from the nearest power line, you may be better off using an off-the-grid solar power system with a combination of active and passive technologies.
- Electricity costs – California has some of the highest electric rates in the country, making an Aptos home solar power system a very good investment.
- Financial incentives – California is one of the leaders in providing financial incentives to homeowners who install a solar power system. Contact POCO Solar to learn more.
- Shade – One factor that is always present in regard to the use of a photovoltaic system is that of shade. If you are in an area that is heavily wooded, then you need to decide if the trees blocking the potential part of your roof that will house the PV panels need to be cut back or removed. If you are in a denser neighborhood, the trees blocking your roof may not be on your property, and thus you may not be able to have them altered. There are some systems with a set of panels mounted on a backyard tracking system that can be as effective as a roof system. Solar meters can tell you not only the amount of sun a certain position is receiving, but can also project the level of sun expected to be in that location for the whole year.
- Roof pitch and direction – Regarding direction, south facing roofs are better for solar panels, but systems can still produce ample output if they don’t face that direction. Even if a roof is 45 degreesoff due south, the reduction in electricity production will only be about 4 percent. Regarding pitch, a 30-degree angle is recommended but not necessary. A pitch of even 45 degrees can work.
If you have any other concerns or questions regarding your potential Aptos home solar power installation, please call POCO Solar at (408) 970-0680.

In order to get the most out of your Monterey solar water heater installation, you need to have a large enough area for the solar collectors, and an area that provides the proper sun exposure. It would be ideal if you have a flat roof, because it is very easy to orient the collectors so that they directly face the sun. If you have a pitched roof, it is best that the collectors are installed on the south side.
The size of the area depends on the amount of hot water you need daily. It will also depend on the kind of collectors that are used, your geographic location, and the orientation of the collectors.
There are two kinds of solar water heater systems; active and passive. An active system does not require a tank located on the roof and uses a small pump to circulate the water that is heated through solar power. A passive system does not use a pump, but the tank (or tanks) has to be installed on the roof.
If you choose to use an active system for your Monterey solar hot water heater installation, then you will more than likely not need structural calculations or roof bracing because the weight of the collectors used are normally well within the load limits of the roof. If you want a passive system, however, some simple structural bracing may be needed.
Maintenance and operation
You will probably not have to do very much, if anything at all, once your system has been installed and in operation. Solar water heater systems are used year-round and are totally automatic. An active system has a small electronic control that has indicator lights that will inform you of any sort of malfunction. Make sure you do not ignore the instructions included in your system in regard to freeze protection, because freeze damage is possible anywhere in California.
If you have any other questions regarding a Monterey solar water heater installation, please contact the expert professionals at Poco Solar by calling (408) 970-0680 or (650) 324-0680. Let us put our 25 years of experience in the solar power industry to work for you.
