Solar Swimming Pool
Shallow water in a pond or lake tend to be more heat than the water that is in a deeper place. This occurs because the sun can warm a basic pond or lake in the area that is more shallow, and that means water that is above become hot.
With the same principle, the sun can be used as a water heater in the building and swimming pool. Most of the water heating system that uses the sun as a source of heat, consists of two main parts: the sun collectors and storage tanks. Collectors that are commonly used flat plate collectors. Collector consists of thin flat box with a transparent top cover part and facing towards the sun. Small pipes that is in the box bring liquids, which can be water or other liquids, to be heated. Pipes is paired on the black plate that serves to absorb heat from the sun. After a heat form in the collector, the liquid is in the pipes will be hot.

Solar Energy Applications
Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.
There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.
Photovoltaics System
Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.
Solar Cell Module
Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.
Thin Film Solar Cell
Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Solar Hot Water
Executive Summary about Solar Hot Water by Anna Williams
Solar hot water heating systems are a great way to effectively conserve energy and reduce your energy bill.
Important Facts about Solar Hot Water Systems
- Solar water heaters can be used in any climate.
- The fuel used to run a solar heater is sunshine.
- A solar water heater can reduce your water heating bill by fifty to eighty percent.
- Aside from reducing your energy bill right now, a solar heating system will protect you from future energy price increases.
- When building a new home, or when refinancing, the economic aspect of this becomes even more interesting.
- Using solar power to heat your water will significantly reduce your carbon footprint.
- Solar heaters can be installed in combination with backup systems.
Types of Solar Hot Water Systems
There are two types of systems, “active solar water heating systems” and “passive solar water heating systems.” With a passive system, the water storage tank must therefore always be positioned above the solar water heater collector.
Active Solar Hot Water Systems
There is also the direct circulation system, where water is simply passed through solar heat collector and then routed to the water storage tank for use.
Passive Solar Hot Water Systems
Passive solar water heating systems are usually cheaper than “active solar water heating systems,” as they do not need controls or pumps to circulate the water.
If you live in a warm climate, a passive water heating system might be all you need. Essentially, solar water heating systems consist of a water storage tank and its solar collectors. The solar collectors are used to collect solar energy (which heats water), and the tanks store the heated water. 75% of the energy consumption of the average home is for hot water and heating. The most economical and effective way of using solar power is through the use of solar heating, and solar hot water heaters.
Homemade Solar Hot Water Heater – One of the Easiest Home Renewable Energy Systems You Could Make?
Executive Summary about Solar Hot Water by Denzil De Vries
Installing a solar hot water system is one of the easier projects to undertake if you are keen to create your own home made renewable energy systems.
The key to the solar hot water system is the solar collector. It is just a tank that has been modified to absorb thermal energy from the Sun. So it may be painted black on the external surfaces and have insulation on the internal surfaces to prevent heat loss.
The flat plate solar collector design uses the same principles but is designed to squeeze even more juice out of the Sun. The plate is painted black to again absorb solar radiation and heat. Along the plate is tubing that will hold water. The tubing exposes far more water to the heat than the ordinary old solar collector. This means more water is heated or made hotter.
Where you place your collector is vitally important but is dictated by two factors. It needs to get as much Sun as it can, so a south facing location in the home is best. But it also needs to move water to the boiler system in the home. So the nearer it is to the boiler the better. If the boiler is well located you could position the solar water collector above the boiler and let gravity move the water from boiler and back to collector based on the heat of the water.
A solar hot water system can be a simple as a solar water collector that has no moving parts or electricity to worry about and a connection to your boiler system.
Most people look into a solar hot water heater because they want to save money on their heating bills. With this in mind a solar hot water heater will help to reduce your bills by pre-heating water that goes into your traditional boiler.
