solar power and solar light
1. Solar indoor lights. You can burn up a lot of expensive energy using regular lights inside your home. Solar indoor lighting is an environmentally-friendly and sustainable option in a world where it has become crucial that we seek out alternative energy sources.
Instead of using overhead lights, use solar-powered desk and floor lamps to light up your home at night. Like the outdoor version, these indoor lights capture light energy during the day and store it in small batteries which the lights.

2. Outdoor Lights. You can use solar energy to power your landscaping lights. Solar energy garden lights to light your pathways or gardens are inexpensive and can be purchased in many different styles at your local home improvement store. The solar cells located on the top of the lights gather energy from the sun and store it in small batteries inside the lights.
At night, the batteries power the lights. While earlier versions of solar outdoor lights did not produce much light, recent advances in solar cell and battery technology gave way to some powerful solar powered floodlights. These lights are a great way to see firsthand how solar energy works before you spend thousands of dollars on a complete solar system.
Passive Heat Solar Tubes

3. Passive heat storage tubes. You can purchase innovative greenhouse fiberglass tubes to drastically cut down on your heating bills. The tall fiberglass cylinders – which look like pillars, but are hollow – can be used as room dividers or attractive accents.
You simply fill them with water and place them where they will get a lot of exposure to bright light where they can catch and store energy from the sun to fill your room with heat and greatly reduce your heating bill.
Solar Chargers

4. Solar chargers for electronics. Yes, your cell phone, laptop, MP3 players and many other electronic devices can be charged with solar power. There are several solar-powered chargers on the market that either charge internal batteries, (like in cell phones) or charge C, D, AA, and AAA batteries for use in other electronic devices.
These rechargers come with different size cords to be used with different items. Using solar power to charge the electronic items you use every day can take a chunk out of your electric bill each month.
Solar Water Heater

5. Solar water heater. For a fraction of the cost of a complete solar-power system, you can install a solar-powered water heater system to generate hot water for your home. They can be used in any climate, and the fuel they use—sunshine—is free. These systems include storage tanks and solar collectors.
There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don’t. Most solar water heaters require a well-insulated storage tank with an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank. Same relaxing hot water…less money on your utility bills.
Solar Pool Heating

6. Pools and hot tubs. Many pools and hot tubs now use solar energy to heat the water. Solar power units are designed to assist the gas or electric heating units to save on your heating bills. Older model pools and hot tubs may not have a built-in solar energy system, but you can purchase solar power kits from most pool supply stores to convert your existing heater.
You can even buy solar-powered skimmers to clean your pool and spa. The price you’ll pay for the kit will definitely pay for itself via energy savings.
Solar Oven

7. Solar oven. As mentioned earlier, the first harnessing of solar energy was to cook food in a specially-designed oven that captured the sun’s rays to heat food. These small ovens were originally built for camping, but they work great for outdoor summer cooking as well. Rather than mess with charcoal or propane tanks, solar ovens are inexpensive and easy to use without all the waste of conventional cooking techniques.
These small ovens can cook food at a temperature of up to about 350 degrees and are fully solar-powered. A unique system of glass and reflective material absorbs the sun’s heat like a solar cell and then magnifies it so that it is hot enough to cook. Why not put away your electric or gas grill and use a solar oven for your backyard cooking? It’s economical and it’s friendly to the environment!
These are just a few of the many ways that you start using solar power around your home to see for yourself how well it works and how reliable it is before making the decision to install a full solar system in your home.
One of the most important use of solar energy is to charge up the solar cells of artificial satellites.It is particularly helpful because the satellites go around the earth for long time and the conventional sources of energy will have a lot of issues in such a situation.

Usos prácticos de la energía solar
El sol es, desde siempre, la principal fuente de energía en la Tierra. Sin embargo, la combustión del petróleo o el carbón han acabado relegándola. Incluso la nuclear, que tanto debate y opiniones en contra suscita, está aún muy extendida, a pesar de los peligros que conlleva. Estas materias primas, además de ser muy contaminantes, pronto serán demasiado escasas como para proveer la energía suficiente para el alto consumo mundial.
Por ello, una alternativa que cada vez cobra mayor relevancia, es el aprovechamiento de energías renovables, dentro de las que encontramos a la solar. Existen dos sistemas: térmico y fotovoltaico. La diferencia radica en sus distintas formas de almacenamiento y, por lo tanto, en sus diferentes aplicaciones; mientras el primero se utiliza en sistemas de calefacción o la obtención de agua caliente, el segundo se destina a la transformación de la energía solar en electricidad.
Energía mediante agua caliente
Estas instalaciones están compuestas por paneles que absorben el calor del sol. El proceso es sencillo; el colector, normalmente plano, transforma el calor en energía térmica, mediante el "efecto invernadero". El calor se almacena manteniendo la temperatura alta del agua que se utilizará cuando sea necesaria. Es importante que el tanque de almacenamiento tenga la capacidad suficiente para cubrir las necesidades de uno o dos días, que también dependerán del número de usuarios de la misma.
Estos sistemas tienen múltiples aplicaciones: la obtención de agua caliente sanitaria, climatización de piscinas, con lo cual podremos disfrutar de largos ba?os durante la mayor parte del a?o, calefacción, refrigeración, ya que para la obtención de frío es necesaria una fuente de calor, aplicaciones en la agricultura, como invernaderos o secaderos, y en la industria, como en plantas de desalinización, ya que no conllevan contaminación. El coste de la instalación completa necesaria para obtener agua caliente para tres o cuatro personas se encuentra a partir de unos 3.000 euros
Sistema fotovoltaico
Este mecanismo puede ser de dos tipos: aislado y conectado a la red. Los aislados están compuestos por generadores fotovoltaicos, que producen la energía a partir de la que reciben del Sol, y acumuladores que la almacenan hasta el momento de su utilización.
Es necesario en ambos sistemas que los rayos incidan perpendicularmente en los paneles. Así, al incidir en la superficie, producen el voltaje que se aprovechará.
Los conectados a la red están compuestos por:
Placas solares: al recibir los rayos, actúan como generador.
Regulador de carga: evita que se produzca una sobrecarga en los acumuladores.
Acumuladores, los proveedores de la energía que consumimos.
Inversor, que transforma la electricidad acumulada en corriente alterna, lista para consumirse.
Dos contadores: uno de ellos para contabilizar la energía que se aporta a la red y otro para medir nuestro propio consumo.
Ventajas de los sistemas solares
Una de las principales es que suponen un considerable ahorro en la factura de la luz. Además, los mecanismos fotovoltaicos necesitan sólo un mantenimiento básico al carecer de partes mecánicas. La única tarea necesaria es la limpieza de los paneles, que, además, resisten condiciones climáticas extremas. Asimismo, es posible aumentar la potencia a?adiendo paneles adicionales.
Aunque su precio puede resultar en principio algo elevado, y la instalación debe correr a cargo de profesionales, resulta una buena inversión a largo plazo. Además del ahorro que supone, incluso se obtiene beneficio de ello, ya que la energía que no consumamos se vende a las empresas de electricidad, que están obligadas a comprarla; desde éstas pasará a la red eléctrica general. Así, además de rentabilizar la instalación, colaboraremos en la extensión de una energía limpia e inagotable.
