America will never be eco… unless you have a peoples eco revolution to make the corporates serve the people ….not the people serve the corporates…. Why the donaldduck / halibut / cod… doesnt Bill Gates buy out the logging companies in the amazonian rainforest and cease production and make the indians the keepers of the forests?…and give the deeds to the UN to hold as an area of worldwide scientific interest.?.

Sooner or later, every roof needs to be replaced, usually due to the long-term effects of weathering. If a residential roof is more than 20 years old, it is a prime candidate for reroofing. To determine if you need a new roof: On the ground, walk around your home with binoculars and inspect your roof for cracked, curled or missing shingles, as well as any excessive loss of the protective mineral granules. DO NOT CLIMB ON THE ROOF; walking on the roof is dangerous and can damage your roof.

Most solar systems either rest directly on top of the roof or are suspended just above the roof on brackets. We can mount on top of a roof, but prefer to fully integrate the panels into the roof because: Our roof integrated panel provides a very attractive low profile when integrated into the roof covering. Being sunken below tile level it’s actually lower than a typical rooflight. There are no tiles or slates hidden under the panel which are inaccessible for maintenance or renewal.

Not necessarily. Leaks can result from flashings that have come loose or a section of the roofing shingles being damaged by wind. A complete roof system failure, however, generally is irreversible and your roof will need to be totally replaced. Sectional damage can be the result of improper installation such as using staples to roof the home, or the nails are too short to get a good grip on the sheathing under the shingles. Also the wrong shingles could have been used for the house.

Although there are rare exceptions to the rule, most solar panels are either bolted to or mounted on the existing roofing material and must be removed before a new roof can be installed. Because solar panels are charged using a type of antifreeze, they will have to be removed and reinstalled by a licensed plumber who can insure that the job is accomplished properly.

With cedar shake roofs - Most roofs start telling you they need to be replaced when the shakes start to crumble under your feet or when you start finding them in your yard after a wind storm. With composition shingles - These usually wear out in a more discreet way. Granules start coming off leaving black patches showing. Shingles also start to curl at the ends. In general, some people think if a roof leaks they need to replace it. Unless it's an older roof, leaks can usually be repaired.

In producing this resource we didn't want to use actors but wanted to profile young people in their own workplace. Many of the young people profiled have won awards and been recognised by their respective industries. It is a privilege to access many of these work environments for filming and we feel that this is a more compelling experience rather than seeing young people in a boring studio.

In some cases, no. Leaking can occur because some flashings have come loose or because a section of the roof has been damaged. A roof failure, on the other hand, is generally irreversible and occurs from improper installation, choice of materials, or from the installation of a roof system inappropriate for the home or building.

Any time is a good time. Roofing materials are safe to install year round in our service area, which stretches roughly from Baltimore, MD to Richmond, VA. Our winters are relatively mild so we work all year round, weather permitting. Homeowner maintenance should be confined to roof inspections in both the fall and spring to check for cracked or curling shingles, and to cleaning rain gutters filled with dead leaves and other debris.

In late 1994 the Board of Supervisors passed an ordinance stating that all shake roofs installed after that date shall be fire-retardant treated class B and of a type certified by an approved testing agency.

Today solar collectors are typically integrated into the slope of the roof. This method of installation gives the solar collector the appearance of a quality, opaque, glass skylight. In most cases, since the piping is not seen, it actually improves the appearance of the home because it looks like an elegant, expensive skylight. ECS offers a free solar site survey to determine the location of the solar collector, and to verify that you will not have any collector shading problems.

Solar reflectivity (or reflectance) is the fraction of the solar energy that is reflected by the surface (i.e., roofing membrane) back to the sky. White membranes have the highest solar reflectivity, while black have the lowest. Highly reflective roofs lower roof surface temperature.

If only the collector is mounted on the roof it should blend into the roof design quite well. Apricus AP solar collectors are very thin and can be flush mounted on a roof. From a distance they look somewhat like a skylight. You may have to check with your local council regarding building restrictions when installing your solar collector.

The solar panels can be placed on the roof of your house, cabin, cottage, on the ground with a mount or attached to a pole. For optimal performance, the panels must be immersed in full sunlight on the south-facing side of the roof.

For most people, solar water heating is the most economic and practical way to use renewable energy at home (apart from buying renewable electricity and using renewable heating systems) and it can provide 50 to 60 per cent of your hot water over the year. Solar electric (photovoltaic) panels are ideal for remote situations where there isn't a grid connection, but can be expensive compared to mains electricity. The government has introduced a grant to offset some of the cost.

No, the Solar Electric Modules are very lightweight. The combined weight of mounting material and modules is less than 3 lbs per square foot.

We mount solar panels on all sorts of roofs, from flat to near vertical, from shingles to tile. We attach the panels to supporting beams inside your roof. In 25 years of installation and service, we’ve never had panels damage a roof. Only hurricane force winds capable of lifting the roof itself would be capable of damaging our panel installations.

Yes. Most commercial solar electric systems are installed on flat roofs on “tilt-racks” which put the panels at the optimum angle and face them in the right direction. It’s not a problem.

Each spring and fall, for a period of about three weeks, satellite-delivered channels can experience solar interference or sun spots. These outages affect different channels at different depending on which satellite is used to send the signal. They usually do not last any longer than several minutes each day during this time. Reception will get snowy, gradually get worse and then get better.

Under no circumstances are clients allowed to stand up through the sunroof of the limousine once the vehicle is under way. If clients would like to take a picture standing through the sunroof we will allow this only before the trip begins. Our client’s safety is our number one concern. Should the vehicle be struck from behind or become involved in any other type of accident while someone is standing through the sunroof serious injury is almost guaranteed.

Yes. Tests are being carried out on solar panels that can properly power the Silver Pulser (as well as the Silver Maker, Zapper, Bio Tuner, Water Ozonator, even the Magnetic Pulser, ). Please check our Products Page from time to time. Keep in mind that solar panels are better used to recharge the batteries that can then be used to power the units.

Yes, but not on the main house roof. This is because Chester city centre, where I live, is in a Conservation Area. As a result, we are probably one of the few homes in UK to have an outside toilet with 100% solar hot water. The panel is poorly positioned, but it still does its job OK. It is due west facing, but its main illuminance problem is from shading. A huge ugly council tower block (the environmental strategy unit used to be based there!) overshadows it until noon for 7 months of the year.

Disconnect the solar panel from the battery. Then, with your meter set to DC voltage, put the red wire of the solar panel to the red lead of your meter, and the black wire of the solar panel to the black lead of your meter. This will give the voltage the panel is producing Next, set your meter to DCmA or DC Amps and reconnect the leads as previously described. This will show you the current output of the panel.

It is best to discuss this question with Piranha or your nearest Agent. We will ask your needs and can offer advice about which technology would suit you best, your different power requirements, what sort of vehicle is it for? (4WD, Shed, Yacht, Caravan).

Sunlight is composed of photons, or particles of solar energy. These photons contain various amounts of energy corresponding to the different wavelengths of the solar spectrum. When photons strike a photovoltaic cell, they may be reflected, pass right through, or be absorbed. Only the absorbed photons provide energy to generate electricity. When enough sunlight (energy) is absorbed by the material (a semiconductor), electrons are dislodged from the material's atoms.

Solar panels can either be used for hot water, which doesn't affect the heating, or it can be used for heating. As with heat pumps, the water is at a lower temperature than a normal boiler. This is ideal for underfloor heating, because this also works at low temperatures. Care should be taken when designing underfloor heating, as the flow temperature depends on underfloor heating pipe work centres. See www.ecoheatpumps.co.uk for more details.

All Suntech solar panels have a solid aluminium frame permitting the user to bolt the frame of the solar panel to a fixture, typically a backing plate or mounting arrangement.
