Water Heating Water HeatingSolar thermal, active and passive systems for residential use. An active system is one where the exchange fluid is actively pumped from the storage tank through the collectors and back into the tank. A passive system is usually an integrated collector and storage tank, while being simpler in components than an active system, Take me there.
Photovoltaics The basics of the revolutionin solar electrical systems lies in the ability of small silicon cells to convert sunlight directly to electricity. Remote locations such as billboards, road signs and other areas where it is cost effective to install solar electric systems with battery backup are becoming more and more common. Take me there.

The need for proper flow rates is essential, no matter the complexity of the design. If a solar system is added to the pool proper sizing of the pump and filter also becomes important in the overall performance of the solar system.
The real trick is to balance the flow rates and head requirements of all the equipment so as not to adversely affect any portion of the pool. Pool sweeps, especially high pressure pop-up head systems require special attention and sometimes require booster pumps for solar loops or larger filter designs.
The total pool capacity is determined by first arriving at the surface area of the pool. As most heat loss is at the surface, this is a figure to be saved for later use. Second, determine the average depth, and finally multiply by 7.5 gallons per cubic feet to attive at the total gallons.
Figure (1) Example...A=14' and B=16' with L=32' A) 14' + 16=30' divided by 2 =15' ..average width. B) 15' x 32' = 480 sq.ft. Usually a factor of .90 is used to account for the freeform nature of this pool or a total of 480 x .90= 432sq.ft. To gain a more accurate average width and skip using the modifier of .90 simply take 4 or 5 width measurements and average them by adding all together and dividing by the number of measurements taken.
The roof mounted systems require, in some cases, additional pumping power to move the water from the ground level, through the collector array, and back into the pool. Most often this is the case with two story roof applications. typically the use of oversize piping can eliminate this need in the case of single story residences, as the pool is usually plumbed in 1 1/2 inch PVC and most solar systems only require 25-50 GPM.
Competent pool designers understand the relationship between pipe sizing, flow rates, head pressures, and the appropriate pump and filter sizing to have a balanced efficient swimming pool design.
When adding a solar system to a pool the overall flow parameters of the swimming pool must be considered when choosing the components of the solar system. There is nothing worse than taking a perfectly functional pool and to save a few dollars on the solar system, wind up with key elements of the pool not working or suffering reduced life spans.

The Physics of Pool Temperature A pool loses heat at night or in inclement weather at a quantifiable rate, this rate is then used to determine the amount and type of heat needed to keep a pool at a given temperature.
is an ambitious plan. But bringing solar energy to a million public and private U.S. rooftops—and the environmental and economic benefits that come with it—is worthy of everyone's attention.This large-scale U.S. deployment of solar energy technologies will reach schools, libraries, private homes, and large and small businesses. It will take advantage of recent efficiency and durability improvements in solar energy technologies. And it will trim the costs of these technologies through the economies of scale of substantially increased production to meet increased demand.
Key features of the initiative involve - Developing a pool of existing federal lending and financing options Soliciting voluntary participation by state and local governments and groups - Accelerating the use of solar energy systems on federal buildings Leveraging other financial support and incentives, both current and proposed.
Objectives The Million Solar Roofs Initiative will increase momentum in the U.S. for more widespread use of solar power. Increasing the demand for solar energy systems, photovoltaic, solar hot water, and solar space heating systems will lower the cost of these technologies, making them accessible to more people. And this will put the American solar energy industry in a stronger position in the expanding international renewable-energy market. Slowing greenhouse gas emissions. Clean energy from the sun replaces power sources that pollute the environment. In 2010, Million Solar Roofs will reduce annual carbon dioxide emissions by an amount equal to what is now produced by 850,000 automobiles. While solar energy is a long-term investment to slow greenhouse gases, the initiative is essential to drive the economies of scale of manufacturing so that significant pollution prevention can occur. Expanding our energy options. In 2010, Million Solar Roofs will produce the same electricity generating capacity as 3-5 coal-fired plants. Solar energy expands our energy options and makes us less dependent on foreign supplies of oil. Dozens of electric utilities, including the Sacramento Municipal Utility District, Detroit Edison, and Colorado Public Service Company, are selling electricity produced by solar energy. Others are promoting solar water heating systems as an effective means of saving electricity for water heating.
Creating high-technology jobs. By 2010, approximately 70,000 new jobs will be created as a result of new demand for photovoltaic, solar water-heating, and solar space heating technologies. In 1997, five new photovoltaic production plants opened in the United States, and six more are planned for 1998.
Building on existing momentum. Million Solar Roofs supports companies and consumers who have already made the decision to invest in solar energy. For example, 68 utilities, serving 40% of U.S. electricity consumers, have formed a consortium to buy $500 million worth of photovoltaic panels by 2003. Under the USH20 framework, utilities are also working together to expand solar water heating programs.
Marshalling existing federal resources. Million Solar Roofs will drive action by aggressively encouraging the federal government (the single largest energy user in the world, spending $3 billion per year on electricity alone) to purchase cost-effective solar; using existing federal lending and grant programs to accelerate non-federal purchases of solar energy systems; and coordinating federal activities to bring the cost of solar energy down.
