Small roof-mounted units are perfect for keeping a garage, shed, doghouse, or chicken coop cool in the summer. There are also free-standing solar-powered fans you can use on a patio, patio, or kids' play area.
Swimming pools are one of the greatest joys of summer for children and parents alike. Everyone is excited the first day the pool is opened—except when the pool is just too cold to jump into it.
To fix that problem, you can add a solar blanket that will warm the water. The basic floating blanket is a passive heating device that works simply by absorbing the sun's heat and transmitting it to the water.
However, if you want to get a little more high-tech, you can also install a full-fledged solar water heating system. This utilizes solar heating panels that are mounted on your roof to collect the sun's heat, which is transmitted to the water through a series of tubes looping through the panels. As the water is slowly circulated from the pool up through the solar heating panels and back to the pool, the water temperature in the pool is gradually increased. There are two types of solar systems that can be used to replace traditional water heaters powered by gas or electricity.
Active solar hot water systems make use of mechanical circulating pumps that circulate water or another fluid from rooftop heat collection panels down into a storage tank.
Passive hot water systems have no mechanical pump components, operating by the simple physics of heat naturally rising. There are two types of active solar water heating systems:. Passive solar water heating systems are considerably cheaper than active systems, but they're usually less efficient.
There are two basic types of passive systems:. Obviously, there can be a substantial investment in installing a solar water heater. Yet doing the math may prove that it is a cost-effective idea when you calculate the energy costs of operating a standard water heater over 20 years or more. The energy of the sun can also be used to heat an entire home in one of two ways. These are systems for the homeowner truly serious about renewable energy, as they involve a substantial investment.
Whole-house hot water systems are the big-scale version of the same kind of solar system that can replace the water heater providing hot water to faucets. Like that system, whole-house heating systems use solar collector panels to heat water that circulates through tubing lacing through the collector panels. But rather than being stored in a relatively small tank for use in plumbing fixtures, this hot water is also circulated through piping that provides warmth to radiators or radiant flooring tubing through the entire home.
These systems often serve both purposes: heating water for use at faucets, as well as providing whole-house heating. These are big-scale systems that use quite large solar collector panels on the roof and sophisticated tanks and circulation technology. Solar hot water heating systems are more commonly used in businesses, but they are also an option for residential use.
There are also full-house heating systems that use hot air rather than water or another liquid as the medium for moving warmth around the house. These systems work by gathering the air that has been heated by the sun beating down on a roof or an exposed wall, and circulating it through the home.
For example, clay roof tiles may have air channels built into it that allow the warmed air to circulate. Houses that use hot air solar heating often have roof or siding surfaces designed to absorb heat. Many systems have some form of a powered circulating fan to distribute warm air. These systems are often designed to heat single rooms only.
You can see this type of system as a much more sophisticated version of the old-fashioned sunroom, which was kept warm by sunlight beating down through large windows and heating up a stone or ceramic tile floor.
A drawback of some hot-water heating systems described above is that they require a pump to circulate water from the solar collector to the holding tank. Normally, these pumps are powered by household electrical service, and doing so in some ways consumes some of the energy you hoped to save by installing the system in the first place.
Solar power is also scalable. This means that it can be deployed on an industrial scale, or it can be used to power a single household. The only limitation is our ability to convert it to electricity in a cost-effective way. Fortum has over power plants in total: hydro, CHP combined heat and power , condensing, nuclear, solar and wind.
Solar power - unlimited source of energy Solar power is the key to a clean energy future. Renewable Renewable Solar panels produce electricity by transforming the continuous flow of energy from the sun to electricity. Key numbers for including associates MWp operating capacity. Solar energy - a clean source No greenhouse gas emissions are released into the atmosphere when you use solar panels to create electricity.
No fuel to burn After solar panels have been installed, operational costs are quite low compared to other forms of power generation. Solar power and the environment As a renewable CO 2 -free power source, the environmental impact of solar power is significantly smaller than other power generation methods. In some cases, solar PV may be installed on an adjacent structure such as a barn or mounted to the ground, and then connected to the meter using underground cabling.
Other uses for solar energy include utility scale solar PV farms that can generate enough electricity to power entire cities. An even more efficient solar technology is concentrated solar power CSP. That thermal energy may be stored before powering a generator, which makes it a more flexible source of electricity than solar PV. Uses for solar energy extend to water heating systems. Most solar water heating solutions create hot water that is consumed inside the home.
Solar water heaters usually have a five to ten year payback according to the U. Department of Energy DOE. Another application of solar energy, especially in the southern and southwestern U. Water is circulated to a collector where it is heated by sunlight and then pumped back into the pool. Typical uses of solar space heating systems include powering radiant floors or pairing with a Forced Hot Air FHA system to heat a home.
Passive solar home design can also heat homes and businesses in the winter by taking into consideration the placement of windows and the selection of materials used in the building. Solar ventilation solutions such as solar attic fans can reduce the burden of your HVAC by helping to cool your home during the summer. One innovative product is the Solatube solar attic fan.
Solar lights have become ubiquitous and can be found everywhere from home landscaping and security lights to road signs and street lights. These solar lighting technologies for your home are inexpensive and readily available from basic to high-end designs everywhere from your local hardware store to online shopping websites such as Amazon.
