Solar Power Electrics

Archive for January, 2010

Solar powered lights for home gardens have come along way.  They used to be unreliable because they broke down easily and only turned on for a few hours before needing to recharge.  But in the past few years, the technology behind solar powered lights has improved greatly and solar powered lights has become one of the best way to decorate the exterior of homes.  Great thing is they also save money at the same time.  There is nothing more mesmerizing than colorful display of lights on a house in the dark of night.

Still, when in the market for solar powered garden lights, it is best to first understand how they work.  First of all, they are not like the familiar electric lights we use in our kitchen.  Solar power lights do not use electricity or battery.  So they attract many homeowners who want to be decorative and, at the same time, save money.  But, one thing to keep in mind is that they rely on optimum placement in the garden to work properly.

Solar powered outdoor lights use solar panels to absorb sunlight in the daytime.  The panels are connected to solar cells that turn the sunlight into energy which is then stored in a battery.  At night, the battery powers the bulb until energy is used up.  The cycle repeats the next day so that light is available at night.  The great advantage of a solar powered garden light is that it never needs any electricity.

Using solar powered lighting is simple, but there are a few small pointers to understand.  For example, in order to receive full performance, there must enough exposure to direct sunlight in order to charge the battery.  Now, some solar powered garden lights can recharge using any daylight including during cloudy days.  But having direct sunlight is the best source.  This means that in most places of the world, a solar powered garden light will perform better during summer than in the winter.  And that’s just normal.

Also, by it’s nature, a solar power bulb is not as powerful as a typical 60 watt bulb.  So lighting may seem dim when compared to traditional light.  But it’s enough for some purpose, such as pathway or driveway lighting and evening garden decor.  It is best to use as many solar lights as possible since these do not use electricity.  The more lights, the better.  Additionally, a solar powered LED light might be a better pick than non-LED light because it is brighter.

To summarize, solar powered lights are fantastic for low light duties such as pathway lighting, accenting garden floral arrangements, or mood lighting.  They don’t use electricity and can save money in the long term.  If the need for light is for reading or other activities requiring brightness, then it’s better to use the traditional light bulbs.

I think they are originally from Germany but I saw them in Mexico. They used to be done with electricity but now there are some that use solar power. Usually done with a push of a button mounted on a wall.

Switchable glazings (sometimes called "smart windows") can change properties such as shading coefficients (the amount of solar heat gain allowed) or visible transmittance (amount of visible light that passes through a window) in response to an electric current or to the changing environmental conditions themselves.
There are only a few manufacturers that offer these technologies now (Sage Electrochromics at www.sage-ec.com and SPD Technologies at www.infinitint.com)

This is a larger Stirling engine that has a 12v DC Permanent Magnet motor operating fixed as the flywheel bearing. It produces 15 Volt max with NO LOAD. This setup as is produces about 15 watts. The heat sink is a water cooled tank that is a bit short for the displacement piston but does work. I will be adding some heat sinks soon and testing it with the 56 inch dish and a Fresnel Lens. The motor/generator has an additional pulley that the other engine I have may be tied to. The water can be fed continuously or as a tank.

When it comes to landscaping there are many things which can be done in order to make it look impressive. There are many different features and ideas to try and one thing that is sure to go down well is landscape lights.

The great thing is that there are quite a few different lights which you can get for the landscape in order to cater for everyone’s needs. Also, the great thing about them as well is that they are very easy to install so everyone can enjoy them with no hassle and no fuss.

What Can Landscape Lighting Do For You?

There are some great benefits of adding lights to your landscape area. Not only do they add a touch of class but they can add a sense of security to the area and even the house. The lights can really help to brighten up any dark areas around the yard and they can also make it easy to see at night whilst you are out in the garden. They also help the landscape to look extremely impressive and it adds that little something extra to the balance. They really are an inexpensive way of adding extra charm and style to any landscape.

Different Types of Landscape Lighting

When it comes to the lighting for the yard area, you will find that it will be powered from two different sources. The first option is that the lights use a line voltage fixture, which will be connected to the power supply from the house. The great thing about this option is that the wires will be underground so they will not be sticking out and causing a safety hazard. You will find that this type will be used for the bigger landscapes and also by people who are experienced with electrics. It is always best to get someone professional to do it if you are not sure yourself on how to do it.

The second option is where the lights use solar light fixtures to absorb the energy from the sun, in order to charge up the batteries in the light. These are very easy to use and easy to install as well as being cheaper too. So, that makes the second option the safest and the easiest for most people.

Landscape Lighting Is a Great Idea for entertaining

It is a great idea to add lighting to any landscape and it can come in handy for when the nights draw in. It allows people to stay outside in the warm months and enjoy socialising or relaxing in the garden. They are absolutely great for entertaining and it really does help to make people feel very welcome. Overall you really cannot go wrong with a little landscape lighting.

In one way or another, almost every form of energy we use originates as energy from the Sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly, we get power from plants grown by the Sun, oceans heated by the Sun, and Earth’s weather systems sustained by the Sun. Even the energy stored in fossil fuels originated as energy from the Sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells. By building 12 models and conducting 30 experiments, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. You will build different types of vehicles and machines to demonstrate how gears can convert and transform power for different needs. There are 320 parts, which are also compatible with the other Physics kits. The 64-page book offers illustrated instructions for the projects. Developed with Greenpeace in Germany. Ages 8 and up.

I would like to hear from a Do-It-Yourself type who has actually built a system.

You can do this yourself, but if you want to tie into the electrical grid, it is recommended that you hire an installer.

This is a great article on how to choose the right renewable energy for you: http://howto.altestore.com/Getting-Started-Renewable-Energy-Sustainable-Living/Renewable-Energy-Options-Which-Alternative-Energy-is-Right-for-You/a41/

From there, you need to assess your electric loads so that you can accurately size your system.

Here is an excellent load calculator: http://www.altestore.com/store/calculators/load_calculator/

Then, you need to find an installer and do research on incentives and tax credits.

Solar power electricity can also be called as solar photovoltaic (PV) systems. It strikes into the same abundant and free energy resource as solar thermal technology. PV cells consist of semiconductor materials that convert sunlight into electrical energy thorough the photovoltaic process. On their own, the voltage and current level produced by individual cells are not particularly useful, but when many cells are connected together to form modules (panels), more practical energy can be produced. We call this energy as Solar Power electricity.

Various materials and technologies exist for solar power electricity, all have their own specific characteristics, advantages and disadvantages, and lot of it varies from consumer to consumer based on their preference and requirement. Despite the fact that they cost more than the other renewable energy sources, they actually offset the most expensive energy bought and used in home electricity. Beside the rise up of electricity prices solar power electricity has become more attractive more domestic consumers.

Solar power electricity lacks any mechanical components, it is silent in operation and highly reliable. It has no moving parts so it works perfectly well without any need for maintenance. The modular nature of PV allows for system design and rating to be amended at any time easily. Additionally, PV can be integrated into the fabric of the building as well as being mounted on the roof, or into a specially design frame. PV produces on-site electricity, bypass all the losses associated with electrical transmission over the national grid and saves hundreds of kilograms of carbon emissions per year in the process.

A well designed system in a suitable location should produce between 700 and 850 kWh of electricity per year. Solar power electricity system of 1.5 and 2.5kWp could generate fifty percent of the electricity requirements for an average home. This adds to its attraction because this is the world of less expenditure and more production, and merely Solar Power Electricity totally satisfies the need of the day.
