How to Warm a pool with Solar panel

Faced with the growing threats of environmental pollution and rising oil prices, the energy sector has now drawn attention to environmentally friendly projects. These are often renewable projects produced from natural substances. A typical example is the solar panel and photovoltaic cells which are increasingly being used for domestic activities, such as heating and electrification. They are extremely energy efficient and based on the best available technology. Today, we are going to see the use of solar panels for heating pools for home use.
The first thing to do before any such project is to carryout a feasility study on the project location and the estimated amount of electricity to heat the pool. This is crutial in selecting the direction for the panel, the number os panels needed and an estimate of the project cost. Worth mentioning is the fact that in ground pools to keep the heat longer than the above ground pools.
Install 3-way valve after the pool pump and filter (return line) so the water can be controlled by panels or the pool (the last panels). Getting the proper valves is important, so that the flow of air can be adjusted to target part of the water or not arrays. Imagine a pool valve, which accepts automatic valve controller if you might want to check the valve or at a different location.
Install the T tube tight three-way value of the return line in the swimming pool. Water returning to the panels to go back in line with the valve. Water is then free to return to the pool panels.
To maintain the same size as the pipe return pipe (typically 1-1/2 "or 2") has two routes, and the solar panel site. If the disks are installed on the roof, plastic Pipe channel to keep the tube firmly in the walls and eaves. On the edge of the roof to install the installation of each tube so that it can be easily removed through the panels, or wind, or replace a roof. Although the solar panels on top, union fittings to make the season off easily. Consider burying a rigid basin pipes to keep the garden looking tidy.
Plastic Solar Panels are available in several sizes, but 2'x20 ', is common. The purchase at least two. Each panel costs about $ 150. You might want to try two before adding. Enough panels of the same area of the pool would be ideal if you can afford them. 18 "diameter Round the pool area is about 254 square feet / 40 square meters Fri panel = 6 panels. However, fewer panels are OK, and it may be best to keep the investment is modest, until you are satisfied that all reasonable concerns and interests. Add to panels require more pumping power, so this is another issue, you'll understand better when you have tried the two panels.
Installation of the roof may be the biggest challenge and the reason to consider placing the site. Use a stainless steel hanger bolts ordered through the Internet, if the local system does not meet them. Think of the roof beam spacing and location of the hanger bolts slightly wider than the width of the 2-foot panels. Rich was born Roof polymer or "to do" around the hanger bolt is to prevent leakage. Tape or aluminum bar, a hole at each end to fit over the panel, and two bolt hangers. Attach the stainless steel and the wingnuts to make a laughing stock panels quickly and easily. In most communities, you must provide a plan to comply with the rules and get permission before doing anything to the ceiling. These factors can install solar panels on an attractive option.
When the solar panels, attach them to each other and the equipment. Pay special attention to why the Board of the tube in or out, so that the water is always imported into and out of UT. Air is trapped in the panels, if installed backwards. When the plates are mounted on the slope would be OUT at the end of the panel is higher.
When the tubes are connected, turn on the pump and open the valve discs. Check for leaks. Theoretically, a higher flow rate, the better (because of cooler water sheets absorb more heat from the sun). You'll probably find that the water returning to the panels are only two or three degrees higher, but over the period of one day this heat throughout the pool a couple of degrees. If the nights are not too cold, you get a few degrees a day. Even a small swimming pool takes about a week is much warmer. We have been careful to keep expectations realistic, but I only have three panels of my South Florida pool, and they are wonderful. Without electricity or gas for heating, I can enjoy the swimming pool 80 degrees or more in about half of the year. This year, two more panels for a total of five warm season. Happy swimming!

How to Buy a Carbon Offset

Carbon offsets are becoming an increasingly popular way for individuals and businesses to participate in solutions to global warming. The basic idea of a carbon offset is to figure out your personal contribution level to the global warming problem from such activities as driving, flying, or home energy use. This contribution is called a "carbon footprint." The term refers to carbon dioxide, the principal greenhouse gas. You can balance out your carbon footprint by buying carbon offsets. Your purchase funds reductions in greenhouse gas emissions through projects such as wind farms, which produce clean energy that displaces energy from fossil fuels. By funding these reductions in greenhouse gas emissions, you balance out, or offset, your own impact by an equivalent amount. Carbon offsets help you take personal responsibility for the environmental consequences of your activities.

Steps

1. 1
   Identify sources of carbon dioxide production in your daily life. For most people, one of main sources of carbon dioxide emissions is driving. Cars and trucks are responsible for 25% of all U.S. carbon emissions. Other sources of carbon emissions include air travel, household energy use, and products that are shipped long distances.
   
   
2. Reduce your greenhouse gas emissions directly. Conservation is easier than you think, and often pays for itself through energy savings:
   • Drive less, increase the fuel efficiency of your car, or consider living without a car altogether.
   • Save on heating and electricity in your home. Use compact fluorescent light bulbs. Install better insulation and windows. If you're feeling ambitious, use solar energy to heat your pool or make your own electricity.
   • Look for locally grown foods by shopping at a farmers market.
3. Calculate your “carbon footprint,” the sum of carbon emissions from all your carbon-producing activities. The method of calculation depends on the activity. For example, if you know the average MPG of your car you can figure out your driving footprint fairly easily. There are plenty of online calculators to help. (see sources below). Some calculators vary in their methodologies, so you may want to read the fine print closely.
4.  Understand how offsetting works. Carbon offset providers balance out your carbon impact by ensuring that somewhere else on the planet, an equivalent amount of carbon dioxide is reduced as a result of your offset purchase. Generally speaking, except with reforestation projects, which can sequester emissions currently in the atmosphere, carbon dioxide isn’t removed from the atmosphere; rather emissions of new carbon dioxide are prevented. In either case, the environmental benefit is the same. Different offset providers have different ways of reducing carbon. Furthermore, the projects they sponsor for carbon reduction can pop up anywhere on the planet, from methane digesters at dairies in Minnesota to wind farms in India. 
5. Find a quality provider of carbon offsets. Because carbon offsets are fairly intangible, you need to take precautions to ensure that your purchase is having the intended impact. Here are some issues to look out for:
   • Are the projects certified according to industry standards and verified by third-parties? A variety of standards such as the U.N. Clean Development Mechanism, Chicago Climate Exchange, Environmental Resources Trust, California Climate Action Registry, Voluntary Carbon Standard, Green-e Climate and Gold Standard provide assurance that projects follow rigorous quality metrics. Environmental Defense and the U.S. EPA Climate Leaders program also have standards they endorse for high-quality offsets.
   • Is the offset provider's portfolio audited? Like a financial audit, this ensures your money was used for the purposes you designated.
