Fotovoltaic

2011-12-02T18:16:00.000-08:00

Many ask why is Fotovoltaic system so expensive?I will post some of the reason why is solar energy so expensive:

A- Solar energy is expensive, which unfortunately may be the only reason why the U.S. and other major energy consuming nations have not yet made solar energy a standard in building in home design today.

Perhaps the number one thing stopping so many people from converting to solar power is the expense.

While it is still rather expensive, it is important to understand that prices have dropped over the past few years. In addition, you have to take into consideration the amount of money you will be saving on your electrical bill.

2- The silicon used to produce crystalline modules is derived from sand. It is the second most common element on earth, so why is it so expensive? The answer is that, in order to produce the photovoltaic effect, it must be purified to an extremely high degree. Such pure "semiconductor grade" silicon is very expensive to produce.

It is also in high demand in the electronics industry because it is the base material for computer chips and other devices.

3- Competition is minimal.

4- Fotovoltaic energies such as solar power are, for the most part, still more expensive than conventional energies because they have only been used on a comparatively small scale so far.

But remember, Solar power and other forms of renewable energy, and the inevitable hydrogen economy that will follow in post oil days will do many things, but only a serious, wide scale and major commitment at a society and individual level will stop global warming.

Fotovoltaic energy will help certainly, and solar power has a role to play in the solution of high cost of energy.

Solar Energy Conservation

There are lots of small investments, as well as personal habits that you can do right now to take an important part in reducing your electricity consumption.

What a lot of it comes down to habit.

As many people have the habit of wasting electricity if they are ready or not, these habits can easily be reversed by starting more energy efficient habits.

Take a look at a few things to start: ENERGY conservation, the first step toward solar

Before finding out how many solar panels you need, you should reduce your current electricity consumption as much as possible. This will make your system more profitable.

Make minor changes and simple in your energy consumption can have a huge impact on your electricity bill.

Magnet Electric Generator

2011-09-29T06:16:00.000-07:00

Today, all suffer from pollution. Electricity companies are the largest contributors of pollutants into the air and water by their use of fossil fuels, which releases toxic gases and chemicals in our environment. To prevent environmental pollution, solar and wind energy to protect a source of energy production. Their advantage is they are cheap and profitable. But they only have a demerit that they are expensive to install and maintain. As a result, magnetic generator is still the only way to produce cheap electricity, which has the advantage of being environmentally friendly.

Their mode of power generation has several advantages. On the one hand, it is both effective and less harmful to the environment. Second, unlike wind turbines and solar does not require much space. It is based on the drive of magnetic forces, it has disadvantages limited. The magnets in the magnetic energy generator that is constantly moving due to their polarity. It is also free of noise pollution. The experts suggested its use as it can reduce pollution by fifty percent.

The use of magnetic power generator is fairly easy to use, even with a new user, because there is a step by step instructions.

In summary, the advantages:

The magnetic energy generator is very easy to use. Even a new user can use the instructions step by step user manual. Using magnetic energy generator, you can get rid of companies that can provide cost more with huge bills. Also the traditional method of production of power supplies is damaging the environment with the son of high voltage in our homes that increase the risk of cancer. The magnetic energy generator is an effective solution to overcome their expenses and their environment clean from pollutants. Experts often considered the most appropriate way to generate clean energy and environmentally friendly.

Consumption With A Kill A Watt

2011-09-26T10:51:00.001-07:00

I was amazed at some of the things I found around the house that draw power just sitting there doing nothing. This thing is easy to figure out and program in your cost per Kwh.A couple of things I found by using this device:
-- the entertainment center costs me $15 a year to have just sit there in standby mode. This is a 42" LCD TV, surroundsound system, DVD player, Wii, If I watch a DVD or play the Wii, it costs me 40 cents a day, or about 3.33 cents an hour.
-- My gaming computer (Dual Core, 500 watt power supply and 19" LCD) cost me $99 a year to run 24 hours a day, 6 days a week. That includes the occasional laser printing and occasional 2.1 speaker usage. So I turn it off more often.
-- Cell phone charger: .86 cents a year, but when charging it costs me $1.73 a year.
-- New coffee pot costs me between 5-7 cents to brew a pot of coffee and let it sit for a couple hours.
-- Toaster at 350-degrees costs me about 11 cents an hour.
-- Dell laptop charger costs me about $1.70 a year to keep it plugged in. It's about a penny and hour to charge the laptop's battery.
-- NOAA handheld weather radio costs 86 cents a year to run 24/7

In the end, it seems like it is only really worth the trouble to unplug the entertainment center when not in use and turn off the computer more often. Sure, everything draws power, but we factored in the hassle of it versus the cost.

We have been unplugging stuff around the house when we are not home, and began to wonder how much we are saving. This thing has helped out in deciding what's worth going through the hassle of unplugging each time, and the results are almost instantaneous. I highly recommend using this device to settle the score in the fight against wasted energy usage or even in helping decide which devices/appliances around your house aren't worth owning due to ridiculous power draws. So thinking about buying a kill o watt tool is great tool to have and start saving money,and it also helps when you are ready to buy a solar system,you will be surprise to save thousand $$$$.

This meter was to calculate which electrical devices and appliances I would be able to connect to the small solar power system I currently have, and to find out which electrical devices and appliances are sucking up the most power in hopes to figure out a way to reduce overall power consumption.

" Inverter Stuff"

2011-08-31T11:00:00.000-07:00

We all know that pv systems depened on much more than pv modules,doing

your homework will help a lot.

I am a certified PV installer and would like to give a few hints. Inverters come in different brands and sizes ,but we need to know their functions and features as well, we can start by identify basic waveforms types and properties.A wave form is the shape of an electrical signal that varies overtime.

Also the basic types of inverters used in PV system,PV modules produce variables DC power.However,most electrical appliance operate using AC loads, so DC power must be transformed into AC in order to be useful.Inverters allow to operate both AC and DC electrical loads.

Inverters for PV systems are broadly classified as either stand-alone or interactive inverters.The difference is whether the inverter is installed on a Pv array or the battery bank.Pv arrays and batteries have different characteristics which affects inverter design.

Stand-alone inverters are connected to the batteries as the DC power and operate independently of the PV array and the utility grid.PV modules charge the batteries but do not directly influence the operation of the inverter.

Interactive inverters are connected to, and operate in parallel with,the electric utility grid.Interactive inverters are loaded by the DC source,not the AC output,so AC loads do not directly impact the operation of the inverter.Before the purchase of an inverter differentiate between inverters and power.Solar inverters used in PV systems include a number of basic and optinal features,such as performance data,operating limits,installation requirements,safety,and maintenance.All the information is located on the inverters nameplate and product manuals.

The principal inverters specification is the power rating.Stand- alone inverter the power rating limit the power it can deliver to AC loads,interactive inverter ,the power rating limits the power it can handle at its DC input.

Inverters are available from many manufacturers from 700Watt for small residential system to over 500KW for commercial and utility scale.

2010-12-08T15:04:00.000-08:00

Yes its great having a solar system installed in your home or business the benefits are huge,especially with government subsidies and rebate programs that make solar the smart choice-financially as well as environmentally.But there are also FAQs to be answer to encourage more people to go solar.Before the purchase of a solar system ask a specialist Is my home roof facing south? Are there any shade obstruction?Although solar system work even when I'ts cloudy.Naturally,cloud cover reduces the amount of solar radiation reaching the solar modules,but the system will generate some power on all but the most overcast days.

Solar installer should analize the site and let the consumer know the total of sun hours in your state or location,and how many sun hours in a yearly basis.Also choose if it is adecuate on the roof or a standalone pole on my yard.Places with shade are not the best options if any trees or nextdoor building create shades need to find proper place beforepurchasing the system,Let professional handle it.If you are a DIY I recommened to purchase a pathfinder it is the best tool for shade issues.

Sometimes people decide to do it themselves, but be awared that installing your own solar system can be a problem with inspectors,building codes,certification,permits, and your power company inspections, hire a solar professional they are qualified and certified.

When shopping for a system,get the price of every item and a separate quote for the system installation.The difference between bids may shock you.Considering the recomandation your solar system cost can be reduce dramatically for your benefit.

Questions to Ask Some Facts Before the Purchase a Solar power Electric System

2010-12-07T11:23:00.001-08:00

1. “How many kw of solar power systems has your company installed?”
Due to the recent spike in solar panel installations, and the decrease in other construction-related businesses, many builders are attempting to start solar installation companies with no solar experience and without proper solar certification. Look for a solar installer with at least 12 installations and a few references.

2. “Is the warranty on my solar panels really 25 years?”
Most solar panels on the market are high-quality and will have a guaranteed output of not less than 90% after 10 years and no less than 80% after 25 years. Any panel should have this warranty, whether it’s made in Germany, China, or America.but make sure they do have it.

3. “Is the warranty on your labor 10 years or longer?”
Some states require installers to warranty their labor for 10 years in order for the system to be eligible for state rebates. Any good installer should have no problem including this.

4. “What is the total output of the solar panel system in kWh/year?”
This is arguably the most important factor in comparing solar electric systems (other than price, of course). If you have solar panels warranted for 25 years, and labor guaranteed for 10, then the brand of solar panel – whether Canadian Solar, SunPower, Suntech,Solarworld or any other – doesn’t matter. What matters is how much power they are expected to produce in a year. Many times less expensive, “less efficient” solar panels will produce more energy in a year at a better price than the pricier, “more efficient” solar panels. When warranties are the same, output is the money-maker, not brand or efficiency.

5. “What is the final cost after parts, labor, installation and rebates?”
Don’t compare the cost of the panels exclusively, or the labor exclusively. Compare the bottom-line cost after rebates. Whoever can give you the most output (kWh/year) at the best price, is the company you should purchase your system

6.I Personaly recomened find a local certified installer,and buy your system locally or on the internet, you will be surprise how much less the overall cost,and will save thousands.

Accumulation Of Sun Power In Your Home

2010-08-01T14:07:00.001-07:00

How can the Sun power your home?

Photovoltaic (PV) cells are an arrangement of semiconductors on silicon. When sun light strikes the cell, a portion of it is absorbed into the semiconductor material. The absorbed light is transferred to the semiconductor which knocks electrons loose, allowing them to flow freely. These free electrons are forced by an electric field to flow in one direction. Once this flow of electrons is created, the current can be drawn off and collected to use in your home.

Unfortunately, electricity is not only necessary when the sun is shining, but also when it is not so we need energy storage, or batteries. Batteries are costly and add regular maintenance to the PV system, but they are a necessity if you want to be completely independent. One way to avoid batteries is to connect your array to the utility grid, buying power when you need it and selling back to the power company when you produce more than you need. In this scenario the utility acts as an infinite storage system. The utility must allow you to interconnect your system to their power grid. This is accomplished by changing your current metering system to a net metering system. When the sun is shining brightly your meter will spin backward while you are producing peak power from your solar array. Your meter will work normally at night when your solar array is not producing energy and you are drawing power.

In a grid-tied PV system, power is generated with solar panels flush-mounted on the roof, ground-mounted in a field, or mounted on the top of a pole. The solar modules produce Direct Current (DC) while our homes and the utility grid transfer Alternating Current (AC). DC power created by the solar modules must be transferred through an inverter and converted into AC power to match the grid's power.

Puerto Rico power companies have a large demand for renewable electricity into their power grid making a grid-tied solar electric array the most common and financially sound way to go solar. Call or email 787-344-1643,joe.cresoto@msn.com

Accumulate Sun Energy In to Electricity

2010-05-17T18:22:00.000-07:00

Solar panels are complex modules of photo-voltaic cells that accumulate sun energy and turn it into electricity; though the system as such seems very complex, from the technical point of view, things are not difficult at all. Depending on the necessity of the user, the solar panels vary in size according to the number of photo-voltaic modules that they incorporate; the modules are hold together by special wiring systems and they function as a field unit. Fiberglass, metal, simple glass or even plastic are used for covering the photo-voltaic cells and creating the exterior of the overall solar panels.

There are some practical conditions to be met for the solar panels to work properly. First of all, the cells in the solar panels have to be connected with each other in order to accumulate and pass on the electric charge. Then, the solar panels have to be protected from the outward environment, since they are very sensitive to aggressive mechanic factors. Thus, you have to take all the measures necessary for the exterior protection against hail, heavy snow and winds. Such precautions are particularly important if your solar panels are made of wafer-based silicon cells that brittle more easily.

You can increase the performance and the life of the solar panels by creating some insulation cover against moisture; hence avoiding metal corrosion is in fact the best way to ensure that the panels remain in good shape. Depending on the type of module structures, solar panels can be flexible if based on thin film cells, or rigid for normal modules. You don't have to worry about the potential overheating of the cells since there are diodes integrated in the structure of the solar panels that decrease temperature automatically. Moreover, manufacturers most often include special ventilation items in the design of the solar panels.

The most competitive solar panels use a combination of mirrors and lenses to focus solar energy on the cells, thus reducing the energy production costs. Companies are offering extensive innovations in the systems, since the demand for solar panels has registered a real boom over the last ten years. With fast decreasing energy resources, and given the high pollution rate that power plants are responsible for, it's no wonder people are looking for alternative energy sources.Solar panels can cover up to 80% of the heat and electricity needs of a household, with the mention that they can be applied for all sorts of landscaping light systems too.

The process of installing solar panels has become a common procedure for many homeowners, given the fact that such systems cover the electricity and heat needs of entire households. Moreover, people with very powerful photo-voltaic panels actually get to sell the energy they produce to the utility agencies, thus contributing to the reduction of the fuel combustion for energy generation.

Solar Power Basic

2010-05-12T05:42:00.000-07:00

Many question are ask, Is it a great idea to go solar or if it's not?What are the advantages?Its solar really good for my business or home.The advantages in going solar are the electricity supplied by a pv system displaces electricity from some other power-generating technology.If the alternative is very expensive,such as a utility connection to a remote location,then the pv system can save you alot of money.

Yes,its great having a solar system install in you're home or business,the benefits are huge but we need to consider a few things.Before we go out and purchase a system we need to know,It's they're sufficient sun hours where i live?and how many sun hours in a daily basis.We need to determine what are our needs,concerns,expectation.Hiring a professional pv installer is really the best choice, he or she can explain the process of determining potetial array location ,methods and diagramming shadding patterns.

What to really consider before purchasing a solar power system:

Need to discuss with the professional you hire,considerations in determining the suitability and condition of existing roof,stuctural systems.

Electrical systems and equipment.

Ask the professional installer to explain the function of an energy audit and idetify opportunities for conservation and energy efficiency.

What you should consider when a proposal is offer such as,estimate for cost,size of system,performance,and value of system.

Identifying these factors begins the site surveying process,which influences all other subsequent system design and installation procedures,including solar equipment,preparing bids,planning and completing pv system.Installer and designers of pv system must identify the customers need,concerns and answer all question a customer should ask.Some customers may be very informed while others may need the installerto explain the types of systems and their costs,functions,and performance.Many solar contractors provide literature to help customers identify their options.

The cost and funding is the major concern to customers.Fortunately,there are many resources for renewable energy,including financing,state and federal incentives,and credits.When discussing your needs with pv installers and have the solar system that cover your needs,ask them for information on applicable funding programs.Later,when the system is figured out,the contractor or installer can use this information to help you apply for these programs.

Also have in mind tha installers must coordinate a schedule and minimize potential delays to ensure the work is completed in a timely manner.The pv installer should discuss the installation process with the customer.Schedule should have flexibility to accommodate unavoidable delays such as weather or shipping delays.
