Solar Energy – a beginner’s look

Solar energy is an exciting field for both scientific study and home and office use, representing the modern drive to find clean, sustainable ways to power everyday life while protecting the planet for generations to come. Solar energy is created by the sun, which plays host to constant explosions of heat and energy. This energy radiates light that eventually reaches Earth, where water, land, and the clouds in the atmosphere absorb a portion.

This light manifests as heat and helps to regulate the planet’s water cycles, including rainfall. Solar energy is converted into food for trees and plants via photosynthesis, and in turn provides the Earth with oxygen and the natural materials necessary for human habitation.

With the many intrinsic and ancient benefits of solar energy we’ve enjoyed over the centuries, it is perhaps unsurprising that modern man has taken it upon himself to truly harness the potential of this natural power source. Solar power is fast becoming a popular way for businesses and homeowners to cut down on energy costs while making a commitment to the health of the environment.

Solar power itself can take many forms, operating for instance through the means of solar panels, which convert radiation from the sun to practical electric energy suitable for a variety of uses, and can store this energy in batteries.

Other common applications for solar power include pumps, switches, and fans for various industrial purposes, greenhouse and other thermal agricultural uses, and special technologies employed in space, such as those used to operate satellites.

Taking advantage of natural solar energy is not only an efficient way to power machines, houses, and more, but is cost-effective as well. Many entrepreneurs and environmentally savvy homeowners find that using solar power greatly diminishes their average monthly electricity expenditures, adding a welcome benefit to the clean and green energy source.

As oil prices fluctuate, and we become more aware of our impact on the global ecosystem, it is becoming imperative that we search for and use renewable sources of energy, and seek to live in a sustainable fashion, so that future generations can enjoy a happy and healthy planet. The use of solar energy through solar power panels and other technologies is an important step in reducing your overall energy footprint, and can give you — and your wallet — a sincere sense of peace and well being.

Solar energy can help sell your home

Anyone who is trying to sell a house knows that some improvements like adding a new bathroom or a complete kitchen renovation may increase the value of a home however most people might not consider that an investment in solar panels or other renewable energy sources may be another positive investment in their home.

According to a study that was recently published by the National Bureau of Economic Research (NBER), solar photovoltaic (PV) panels added on average between 3 percent and 4 percent to the value of a home. This study, which examined homes in California, suggests that homeowners might fully recover their costs of purchasing and installing solar panels when they sell their home. Since solar panels require very little maintenance and are becoming increasingly more affordable to buy and install, this is another way to increase the resale value and marketability of your home. Some of the most common installations in homes are for water heaters, pool heaters and outdoor lighting. As the technology improves and the cost of solar panels continues to drop, more and more homeowners (and potential buyers!) will be looking for solar energy systems for their homes.

Go Invisible: How to protect your privacy on Facebook

There have been a lot of news reports and discussions surrounding Facebook’s privacy policies. Of course, if you are worried about web privacy, canceling your Facebook account is an option, but since many other sites have joined the Facebook Connect network and are utilizing the site’s tools, you will need a Facebook account to be able to use these sites in the future. Plus, not everyone wants to give up their ability to connect with long lost high school buddies or share their latest baby pics with family and friends.

So what to do?

Fortunately, those that have pushed back at Facebook in the past on privacy issues have forced Facebook to provide tools to make you as stealthy as you’d like to be on the site without being completely invisible to those on your ‘friends’ list.

Here’s a guide for making yourself very close to invisible:

While logged into Facebook:

  1. Select the ‘Account’ tab at the top right corner of the screen
  2. Select ‘Privacy Settings’
  3. In the ‘Connecting on Facebook’ section, select ‘View Settings’ – amend these settings to whatever your comfort level is. If you are not interested in letting new people find you on Facebook, then you should change all these settings to ‘Friends Only’. Know that you will not show up in Facebook searches and no one new can add you as a friend.
  4. Be sure that you have chosen the ‘Friends Only’ settings in the ‘Sharing on Facebook’ section – click ‘Apply’
  5. Select ‘Customize Settings’
  6. Be sure that all the drop-downs are ‘Friends Only’
  7. Disable the option for ‘Include me in “People Here Now” after I check in
    8. Select ‘Edit album privacy’ and change all the settings to your meet your comfort level. You can customize them to even be invisible or visible to certain people by selecting the ‘customize’ option
  8. Back on the main privacy settings page, ‘Choose Your Privacy Settings’, select ‘edit your settings’ in the ‘Apps and Websites’ section in the bottom left corner of the screen
  9. Edit the settings for each of the options (on the ‘Instant Personalization’ page, disable the option to see information)

Many of the options listed above are explained in detail by Facebook. However, their goal is to make their site very accessible for both their users and the advertisers that pay to get your information through applications and widgets so they encourage you to share all information by making the defaults very liberal. By limiting the information that Facebook is eager to provide to other users, the search engines and advertisers, you are gaining greater control over who sees your private data. For a regular everyday user that just wants to connect with family and friends, taking these steps returns Facebook much closer to its original purpose.

Survey finds that web users are sloppy with passwords

A new survey commissioned by Webroot confirms that web users are still putting their identities at risk by not employing some simple strategies for password safety and protection.

So what did the survey reveal about web users and why are these findings an issue?

40% have shared passwords with at least one person in the past year

Sharing passwords with a trusted friend or family member may seem like a non-issue because you trust the person you’re sharing it with, but they may leave it lying around where someone not so trustworthy may pick it up.

About 40% of people use the same password to log into multiple sites

Using a password on multiple sites can create a problem because if your password is compromised on one site, the potential exists that multiple accounts could be in jeopardy.

Nearly 50% never use special characters (e.g. ! ? & #) in their passwords

Adding a special character is a simple step that can be used to make it that much harder for someone to guess your password. Another easy to use technique is to substitute numbers or characters to spell out words.

redridinghood becomes  r3dr!d!ngh00d

For example changing the ‘e’ ‘i’ and ‘o’ in “red riding hood” to numbers and characters makes it virtually impossible for someone to guess at it even if they know the name of your favorite childhood book.

20% have used a significant date, such as a birth date, or a pet’s name as a password

In the past, that may have made it easy for only people that knew you to use that information but today that information is often publicly visible on social networks where it can be accessed by almost anyone.

Besides the above tips, it is recommended that you change your passwords periodically and don’t allow your browsers to store passwords for you.

Following these recommendations can save you time and save you money should someone try to hack your accounts.

The future of solar power: Flexible solar panels

As the popularity of solar energy grows, so does the selection of solar equipment that is made available. The big trend in solar energy right now is flexible panels.

Flexible solar panels have many advantages over traditional framed solar panels. The flexible solar panels are lightweight so there is less worry in the installation process and during use. They can also be installed on a semi-permanent basis because they are very easy to remove and install elsewhere.

Probably the biggest advantage is that they can be manufactured in any size or shape so they can be used in unconventional places.

In the past, the biggest disadvantage of the flexible solar panels is that they could only power low-wattage devices however that has changed significantly in the past year as new solar technology has been introduced. The newest flexible panels that are available for commercial applications have the ability to collect more energy than earlier versions.

In the future, we will be seeing even more advances in solar energy products based on this emerging technology.

Solar Energy in China: Here Comes the Sun

Growing demand for renewable energy sources has skyrocketed all over the world, but no where is this more evident than in China.

Take a look at the city of Rizhao where miles of dark tubing cover the roofs of apartment buildings and private homes. The reason? Using solar powered hot water heaters is mandatory in Rizhao. In fact, due to requirements such as this one, China has become the largest producer (and consumer of) solar hot-water heaters. Rizhao’s commitment to solar energy is deep: it has pledged to become the very first city in China to become carbon-neutral.

The good news for all of us is that the surge in solar panel requirements has created more supply, and thus lower pricing for all of us. The lower prices help make solar energy more affordable even here in the US.

As new panels are shipped to us, we will be passing on the new lowered prices to our customers. West Florida Components has just lowered our prices on all new solar panels by an average of 16%. Good news for all of us!

Choosing Batteries for a Solar Energy System

When putting together a solar energy system, like any other project, having the proper parts and tools for the job is paramount to overall success. With quality components and a little bit of know how, you can design and install your very own solar energy system whether for dedicated appliance use or as a complete replacement for conventional electric energy. Choosing the right parts is a big step in the process, and once you’ve decided which type of solar panels to use and how many you’ll need, the next logical step is to find appropriate batteries.

The most important step in choosing batteries for your solar energy system is making sure you purchase a bank with corresponding voltage to the panel array you’ve designed. The voltage of individual battery units on the market is 2; depending on how many individual battery units come in the bank, the voltage of the unit itself will be 2, 4, 6, 8, and so on. Once you’ve established the correct voltage for your battery bank, you can browse the available types and models to arrive at the perfect unit for your system. There are four basic kinds of battery banks widely available for purchase: marine models, and “industrial strength” varieties which include flooded, gel, and AGM features.

The marine models, commonly used on boats and small vehicles such as golf carts, tend to be the least inexpensive, and may be an option for small solar projects or those requiring solar powering for a limited period of time. In the long run, however, purchasing an industrial battery bank will save money. Flooded battery types are an economical option, with a moderate price and a reasonable longevity. These types release gas while charging, and so are not suitable for indoor use. Gel batteries, while a little more expensive, do not release gas allowing for indoor use, and come with a slightly longer life expectancy. Finally, AGM batteries may cost more, but have numerous benefits, including the longest longevity available, lack of gas or other leakage, and superior efficiency.

Taking care to select the battery bank that’s right for your solar system and its application is an important part of the overall design process, and, if done carefully, can lead to many years of nearly maintenance-free energy enjoyment. Shop with quality in mind and give yourself the gift of peace of mind for years to come.

Solar Panels for Boats

Solar panels can easily be installed and utilized on boats for power. There is very little maintenance required to keep them in working condition and if properly installed, the solar panels should last 10 years or more.

The first decision is what kind of solar panels to buy. The most efficient option are mono-crystalline solar panels. Not only are they efficient, they are the most widely available. You might also consider using poly-crystalline panels which are slightly less efficient as the mono-crystalline type. If you have concerns about shade, you can buy the thin film solar panels.

Your next decision is where to install them on your boat. It is recommended that you install them high and aft on your boat, and in direct sunlight. One suggestion would be to install them maybe over the cabin or above the davits. The goal is to avoid installing them where the shadows might affect their performance. If shadows are an issue, consider installing them on a rail along the stern or over the bimini.

If your solar panels are shadowed, even just one complete row of cells, you will not be generating any power. The solution would be to either move the solar panels to a location that is not shadowed or to use a shade resistant amorphous solar panel.

Keep your solar panels operating at their maximum efficiency by wiping off any residue laying on the surface of the panel. Solar panels generally require little maintenance and are able to withstand the outdoors, so think about how you might be able to use them to power your boat.
