Different Types of Solar Powered Electrical Systems
Author: parry
Solar power can supply electrical energy to RVs, homes, and commercial buildings. There are different types of solar power systems that are used. In some cases there is a choice to be made, but in some applications the decision is obvious.
As with any stand-alone system, the batteries are used to store energy that the solar panels collect during the day. It takes an inverter to do the job of turning the 12-volt DC power of the batteries into the 120-volt AC power of most appliances.
Many people whose homes are already connected to the utility grid will opt for a grid-tie solar power system. This gives them the best of both worlds - the savings of the solar power and the reliability of the utility's power. They may also get tax breaks or rebates as incentives to purchase such systems.
The grid-tie system must have a special inverter that changes the DC current into the purest sine-wave AC electricity so that it will mesh with the utility grid. Homeowners can count on the utility grid for electricity on cloudy days and at night. Therefore, they usually do not store up energy in batteries. However, batteries can be used just to be sure people are not without power if there is a power failure on the grid.
A complete stand-alone system is for those who want to be free of the utility grid altogether. Any stand-alone system is the most environmentally-friendly of the solar power systems. While most others use fossil fuels, either directly in a generator or indirectly from a utility company, this system uses none.
The complete stand-alone system is much more complicated than the small stand-alone system. The complete system will contain more inverters, typically two, so that there will be enough current to run large items like air conditioners. Another reason for the second inverter will become clear when one needs maintenance. One can supply basic needs while the other one is down.
The complete stand-alone system will usually be seen in locations where the utility grid does not reach. This is because it is expensive, with its numerous solar panels. Many batteries are also needed to store enough energy for any contingency.
Hybrid systems include the use of solar power with a generator of some kind as backup. The generator may be diesel, gasoline, or propane. Fewer solar panels are needed for hybrid systems than for complete stand-alone systems. This is because the generator can kick in when the solar panels fail to produce enough electricity.
With all the types of solar power systems, it should be easy to find one that works best for any application. It is all a matter of assessing needs and determining which system will do the trick.

Different Types of Solar Powered Electrical Systems
I don’t know exactly but Northumbria university have January Openings
From electronics engineering(in bachelors) can i takeup energy systems/electrical(masters)?
Please reply thoroughly to the above mentioned query and also tell me separately what is the role of electronics engineer in utility company/can one electronics eng. get a job for utility company?[expecting answer from who is in this field]
Cardiff University Have January Intake or not for MSc in Electrical Energy Systems ?

Your field in Master’s doesn’t have to correlate in any way to your field in undergrad. I’ve known people who go from biology or business in undergrad to electrical engineering in masters…you will just have to take some of the basic classes that you missed and you’ll be fine.
If you are an electronics engineer, you will probably have the knowledge on how to model the inputs and outputs of some electrical devices. In utility companies, they may hire you to do the same, except applied to an entire household (modeling household consumption of power), perhaps for the purpose of finding the peak load during some period of time.
Do Devices such as a sharpener or videogame systems or tvs use electrical energy when turned off?
Yes, but very very little. Honestly I don’t think that it is enough to bother unplugging unless you aren’t going to use them for a long time.
Hybrid means combining two ar more different energy sources. This could be solar+wind or coal+gas or any other combination. Search on google or yahoo using words like: hybrid, trigeneration, cogeneration, solar and wind, good luck
Have you built a low-wind-speed electrical energy system?
The winds in our area are 2 to 10 miles an hour over 70% of the year. Do you know any one who has experience with this low-wind-speed? Do you know how I would be able to compute the size of the wind mill I’d need to get say:100 watts of power. I do not want net feed. I just want to run a few lights and possibly a fan. I have considered battery storage and that appears possible. Is it wise? Thanks for the help.
Check Pacwind.com. They offer low wind vertical turbines, however they will need an electric motor hooked to them in order to to start the turbine in low wind conditions but once they start turning they are self sufficient.
Where can i get some useful information about hybrid energy systems??
I need some documents , websites, books, pdf files etc, that give me some info about the use of hybrid energy systems for the generation of electrical energy
