Solar Panels – Can They Hold Up In Bad Weather?

Posted on August 30th, 2009

If you reside an area that has weather extremes, you may be wondering whether solar panels are reasonable for your home. After all, every year roofs are damaged by snow and ice storms, tornadoes, hurricanes and hail.  Is it really wise to install solar panels on a roof that has to withstand those kinds of weather extremes?  Read on for some information to help you decide.

Watch How The Solar Panel is Put Together

It’s easy to appreciate how one might be worried about potential damage to the glass panels as this is how the sunlight is filtered.  Here is the solution: Make sure your solar panels are made with high impact, tempered glass.   Good quality solar panels are made with glass that can maintain its integrity during 60 miles per hour storms dropping 3/4″ hail.  It is most important that your panels should be able to hold up to the same extremes of any normal roofing materials.

Before your solar panels are installed, the contractor has to make sure that the roof itself is able to support the weight of the solar panel arrays.  After that is confirmed and the solar panels are attached to the roof, there’s no reason they shouldn’t stay firmly in place.   If there is a tornado or hurricane the solar panels will normally remain secured to your roof.  For you to lose them now, the roof itself would have to come off.

Take A Look at The Making of a Solar Cell

In areas that experience heavy snowfall, snow may blanket the solar panels and block them from receiving sunlight.  If this happens, the solar panels will not be able to generate electricity and the snow will have to be removed.  However, the snow will not harm the panels themselves.

The bigger concern might be that the roof itself would not be able to hold up under a wet weighty snowfall.  In that event, it would be recommended to clear the snow from the roof as well as removing it from the panels. But in the case of a light snowfall, the warmth retained by the solar panels is normally enough to melt off the snow and keep them clean.

As a final point, look over your home-owner’s insurance policy. Often, solar panels are included in the coverage at no additional cost.  If your policy does not cover solar panels , consider changing to one that does.

If one takes a common sense approach when planning to install a solar system in the home then the risk of damage should be reduced to a minimum Don’t be tempted with building your solar panels using minimal standards just to save money. It may prove to be more expensive in the long run having to replace damaged glass which subsequently leads to damaged cells. It doesn’t have to be complicated. Once your project is up and running you can then begin to enjoy the benefits of your free energy source.

Solar Panels – Will They Work On My House?

Posted on August 30th, 2009

If you have you been thinking about if you can install solar panels on your house, there are several things to consider. The direction your roof faces can make a difference as well as the placement of your trees. In addition, you will need to decide if your solar power system will be tied to the local utility grid. Following is some information to help you decide if solar panels are for you.

Take a Look at This Alternative Way of Using Alternative Energy

An important factor is deciding if your system will be grid tied or off grid. “Grid tied” means that your solar electric system is hooked up to the local utility company. As long as sunlight is hitting the solar panels, they will be producing electricity to power your appliances. During times when your solar panels aren’t receiving sunlight (nighttime, cloudy days), your appliances would be getting power from the local utility company.

Discover One of The Most Frequently Used Methods of Installing Solar Panels

An off grid system runs independently and is not connected to a utility company. This type of system is more commonly found in rural or remote locations where utility poles are harder to access and hookups are expensive. With off grid systems, excess electricity is stored in batteries (similar to car batteries) and a back-up generator is usually utilized. The solar panels produce electricity during periods of sunlight, and at night or during inclement weather, the batteries or generator take over.  

For both grid tied and off grid systems, the pitch of the roof and direction it faces, and nearby objects that cast shade are all factors affecting placement of your solar panels. They need access to direct sunlight for as much of the day as possible to function at maximum efficiency. Large trees that shade the roof as well as taller buildings that could block the sun need to be considered. Of course, each house can have a different combination of these factors and should be regarded individually. Using a site inspection and accurate measurements and surveys, a knowledgeable installer can provide the information you need to determine the best solar panel configuration for your home.

Why we must have home energy saving

Posted on August 29th, 2009

Maybe you missed what is going in the world about the reason we need to preserve energy. We all hear so much concerning this and we can’t simply disregard the truth anymore, the truth of depleting energy sources, increasing electricity cost and global warming. They are all coupled together and impacting one another.

This is why we need to start thinking about power saving.

The primary step in this is simply collect data and become extra knowledgeable. If you want to assist to resolve this, you need to recognize something about the problem. So read, surf the internet and see more articles about energy saving . You can also talk with friends, attend conferences and watch for people in your surroundings that are taking dynamic actions about this. Once you recognize, you can begin looking for solutions

You might feel that it is too much for one person to manage. Actually, you can do a lot!! Individuals influence their families, their neighbors, their co-workers and so on until there are enough to make a difference. Be proactive and influence others to contribute. Involve them straight from the beginning and start with your close people like your family and children.

We all can take active minor steps of lowering our place of living needs and make some home energy saving the problem would be much smaller. Each and every one of us can decrease very easily 10-25% of our daily power use by applying easy steps. For more information watch for electricity saving tips all around you. You can gain much more if you’ll start using renewable energy sources. This may seem difficult but the truth is that everyone with some basic DIY skills can make such a system and with fewer than $200 you can save a lot of money later on your monthly electricity bill

One last thing – don’t think about yourself or our generation. Think about your children and your grandchildren and in what world you see they grow. If we want them to live in a clean, less dirty world, we all need to take action now.

Cut-in Speed in the Doldrums

Posted on August 27th, 2009

An evening walk with my wife revealed to me something about wind turbines. We were walking in a garden that happens to be set in a valley right below two large industrial turbines. I bet these have cut-in speeds of 20 mph (granted- I’m familiar with home, rather than wind turbines, but I’m sure they require a lot of wind). In addition, the two turbines are two different sizes. By swept area, I’d think that one is at least 1/3 bigger. This area also does not ever appear to be windy. I had often commented to my wife how odd I found it that such large turbines could function right there- it feels like the doldrums of a desert landscape

When I was out there last night, I noticed for the first time that the larger turbine wasn’t moving at all and the smaller one was barely moving. “Sort of figures, I thought.” It was a clear demonstration of a particular phenomenon to me- cut-in speed. This is the speed necessary to move a wind turbine. Clearly, the light breeze wasn’t doing it. It simply didn’t move fast enough to move the big turbine or to move the small one in any significant way.

But then something interesting happened. The Earth cooled, night fell, and the turbines started spinning. More interestingly, the larger turbine seemed to start moving slower than the small one, but as night progressed, began moving faster and faster till it seemed to be moving even faster than the small turbine. Despite their weight, the larger blades simply caught more air, making them move faster than the smaller blades.

This whole situation was a clear demonstration of something of which we all need to be aware. When choosing a wind power system, sizing, testing, and careful selection are all of utmost importance. If you live where I do, it’s probably best to either have a small turbine or a huge tower. It also showed me another principle, however. If you live in some of the places where I used to live (shores of Lake Michigan for example), you’d be well advised to buy a larger turbine. I noticed on this walk that when the wind picked up, the larger turbine picked up more wind and moved faster. Not only can it turn faster, it is probably turning a larger magnet. The net benefit is greater- but only if you have the kind of wind necessary to make it turn. Bare this in mind whenever you think about building your own home green power systems.

And as always- good luck building!

Green Power Close to Home

Posted on August 27th, 2009

We so often hear about the benefits of buying locally- buy your food locally, buy clothes made by people in your area, etc. The basic idea is that local products need not be transported, reducing their environmental impact. However, the idea that creating products in your area is valuable extends past consumer products. In particular, it’s incredibly important for the environment that electricity is produced locally.

One argument that immediately springs to mind is that all power is produced locally. Californians aren’t getting their power from New York. However, this is largely out of necessity. Making power a local endeavor can be taken much further.

There are a set of factors at play here, primarily technological. While our technologies for producing power have advanced, our technologies for moving that power have not advanced- or least they haven’t advanced much. There are some promising technological advances on the horizon, but they have not yet come to fruition. Thus, in short, every mile that electricity has to travel is a mile in which the amount of electricity will degrade. By the time all is said and done, you may be left with 80% of the power you created, leaving 20% as waste.

It seems clear, then, that truly green power is created close to where it is used. This prevents the degradation of the signal that occurs in power lines, in transformers, etc. However, that is not the only benefit. Producing local power takes advantage of whatever natural form of energy is avaialable- be that solar, wind or hydro.

Today it is easier than ever to build green power at your own home. Systems have been created that can be deployed in any number of environments, urban, rural, or suburban. You don’t even need much land today to make some of your power from natural sources, and there are numerous guides to assist you in the process. Thus, thinking globally and acting locally is a tenet that we should absolutely be applying to our power systems. Even a polluting plant in your own backyard would end up requiring you to use less energy than the same polluting plant 100 miles away- and you could sell extra power to the utility company. Thus, building your own green power is a goal that you can take as an environmental goal, a conservation goal, and even an economic goal. I would strongly encourage everyone to at least consider the possibilty of building green power in your own home.
