What Do You Gain When You Install Solar Panels
1. Sell Excess Energy from your Home Solar Panel System
- Some states allow you to sell some of your clean energy to the utility company. This great because even when your batteries are full, you get a virtual storage of what you have generated. You can get it back when you exhaust your local energy reserves
- When there is no more sunshine and you start to use the utility company’s power, you are basically getting back what you gave them for storage. Therefore, what you get from the home solar panel kit never goes to waste
2. Minimal Maintenance
- The home or marine solar panels require minimal maintenance if any. You are free to set up the home solar panel kit where you prefer and use it without maintenance for a good while. As long as the installation is properly done, you basically forget that you even use them until you look on your utility bill.
3. Free Energy Source
- The Photo-voltaic home or marine solar panel system gives you a source of energy that is renewable and unlimited in terms of sourcing. As long as there is sunshine, you are guaranteed of free energy.
- Having a Photo-voltaic solar panel system as your own source of power is one of the best ways to cut down on your energy costs. Why? Because you do not have to cut down on your actual energy use.
- What you do is simply use 200 watt solar panel as a cheaper source of energy to supplement what the power utility company is giving you. Most RV and marine boats can also benefit from free energy supply from a 200 watt solar panel.
Store Excess Energy
- You use a bi-directional meter to measure what you sell to the utility company from your solar panel kit, and what you buy from them. Because of the energy credits concept, you are able to sell your power at a higher price and buy it back cheaply.
- If you add the fact that you are not being charged to store the energy from the 200 watt solar panel, it becomes one of the best investment for your home.
- When power outages occur, you will not have to suffer. Whether they happen at night or daytime, You can rely on either your solar battery power bank or solar panel system to supply you with the energy you need.
Low Carbon Footprint
- The solar kit helps you to make a valuable contribution in fighting global warming. There is a small footprint of carbon gasses generated during the manufacture of the solar panels. However, the clean energy we get from the sun, outweighs the initial small greenhouse gas footprint by far.
Increase the Home Value
- The value of your house increases when you install a 200 watt solar panel system. That is because the 200 watt solar panels have almost the same lifespan as your house when installed and serviced properly.
- Investing in the 200 watt solar panels is therefore one of the best investment you will do for your family, house, nation, and our planet.
The Internal Structure of Solar Panels
The sun is the infinite source of all natural energy used by the earth’s systems and artificial sources such as solar panel kits. It is completely pollution free and renewable source of heat and electricity. While it is easy to utilize it as a source of heat energy, using it as a source of electricity requires an investment in photovoltaic solar panels.
The solar cells are the basic units of the photovoltaic solar panels. The solar cells are able to convert the energy of the sun’s rays to electricity without any form of pollution. The electricity is then available for use from the photovoltaic solar panels kit.
Photovoltaic Solar Panels Construction
Manufacturers make the photovoltaic solar panels from smaller units called solar cells. They then pack these cells together in solar modules. Next, they pack the solar modules together in panels to maximize their ability to collect more sunshine. When you expose the solar cells to sunlight, the sunlight’s photons interact with the solar cells to produce direct electric current. You can then tap it for use at home, in marine boats, RVs, space satellites, and other space vehicles.
How Does a Solar Panel Work?
Photons are tiny waves that make up the sunlight, originating from atomic reactions and nuclear reactions in the sun, radiate outwards from the sun to bodies such as the earth. When these photons interact with Silicon atoms of the semiconductor used in the solar cells, they transfer their energy to some electrons. The electrons use that energy to move further from the atomic structure of the semiconductor.
This effect can be compared to the white ball in the game of pool. It knocks on another ball giving it the energy to move around. The end result is the generation of the electric current by the photovoltaic solar cell.
When the electrons are knocked off their atomic structure positions, they move or they are herded to one direction to create an electric current. An electric current is basically the movement of electrons along a conductor’s surface. The generation of energy in a solar panel is all about generating an electric current with sufficient voltage.
However for that to happen, there has to be some kind of electrical imbalance, which acts as a slope for the electrons. This imbalance, also called eclectic potential is the reason why the electrons will flow from where it is high, towards the direction where it is low. All photovoltaic panels must have that imbalance in their solar cells. The greater the imbalance, the greater the voltage or electric driving force generated by the solar panel’s photovoltaic cells.
Doping of the Solar Panel Cells
This electrical imbalance is created by slightly changing the internal structure of the photovoltaic solar panel’s silicon atomic structure. Small quantities of other elements are squeezed into the silicon atomic structure to create an n-type silicon structure, which has extra electrons, and a p-type which has holes, or empty electron positions. Phosphorus is used to add extra electrons while Boron is used to create electron holes.
These two silicon materials are then placed side by side to form a photovoltaic solar panels cell. The extra electron is the n-type silicon natural jump to fill the gaps in the p-type silicon material. The n-type material is then said to be positively charged while the p-type becomes negatively charged.
This charging is what creates the electric potential in the photovoltaic solar panels’ cells. The potential is maintained in the home or marine solar panels cell because silicon is a semiconductor. It therefore has some insulation properties that prevent the electron from moving freely across this electric potential field of the photovoltaic solar panels cells.
Light Photons and Photovoltaic Solar Panels Cells
However, when the electrons are struck by photons, the photons’ energy is transferred to the electrons, giving the boost they need to move across the electric potential of the solar panel’s solar cell. This movement is what constitutes the Direct Electric (DC) current that photovoltaic solar cells produce.
That is basically how photovoltaic solar cells used in satellites, calculators, home or marine solar panel systems, and all other solar powered electronics work. These cells are commonly referred to as Photovoltaic Cells. That is because they depend on the interaction between photons and the P-N junction to generate current. Other types of solar cells are the Concentrated Solar Power and the Solar Thermal used for heating water.
Types, Benefits, and Applications of Solar Panel Cells
The photovoltaic solar panels silicon material that manufacturers mix with other elements to create a potential gradient has a crystalline structure. There are several of them and they have either a polycrystalline or mono-crystalline structure. Most PV panels are reliable and have 20 to 25 years warranties.
The crystalline photovoltaic solar panels’ downside is that they are expensive, rigid, are prone to damage. They also require a lot of manual work to install the home or marine solar panels. However, they are the most preferred for residential solar energy systems because they are more efficient. The other type of solar cell technology is the thin film module technology.
Types of Solar Panel Cells
Polycrystalline Solar Cells
These solar panel solar cells are made from multi-crystalline wafers that fabricators cut from ingots. To get the ingots, fabricators pour the molten silicon into a square mold. They do that to ensure there is minimal wastage when they finally cut the ingots into square wafers.
The photovoltaic polycrystalline solar panels have different shades of blue because of their random crystal formation. They are less efficient compared to the Mono-crystalline silicon crystals; however, they are much cheaper and therefore used to make budget PV solar panels for homes, boats, RVs, and dry camps.
Mono-crystalline Solar Cells
These are photovoltaic solar cells made of single silicon crystal wafers that manufacturers cut from cylindrical ingots. One can cut them into circular shapes, but manufacturers trim them into square-like shapes to minimize wastage. These photovoltaic solar cells have a uniform deep blue color because they are all made from a single crystal. The color comes from the uniform crystal reflection.
They cost more than any other solar cell, but they are the most efficient. Monocrystalline Photovoltaic Solar Cells get used in satellite solar panel cells because of their efficiency. They make the most efficient home, marine, and general purpose photovoltaic solar panels.
Thin Film Modules
These are the cheapest of the photovoltaic solar panels. However, they are also the most inefficient, meaning they require more surface area to produce a given electric power wattage. Their long term durability is questionable and they are only 10% efficient or less in some cases.
They are the most affordable and can be found in photovoltaic solar cells used in calculators and other inexpensive items. They can actually be deposited on sheets of metal or glass as opposed to growing ingots which are later cut to wafers.
The most common film technology used in thin solar panel cells is Cadmium telluride. It is the most effective thin film technology presently. Most of the research is now focused on importing thin film solar cell technology. Amorphous silicon is a good example; this material is used to create a solar panel that can be molded onto most surfaces. They are used to make budget home or marine solar panels
Building Integrated Photovoltaic (BIPV) Home and marine solar panels
The photovoltaic solar panels tiles look like an integral part of a roof system. Manufacturers give them the same shape and size as shingles. They not only have a lower efficiency but they are also more expensive than other solar panels. It is best to use home or marine solar panels tiles in very sunny areas and on buildings with large roofs.
Solar Panel and Solar Panel Accessories
- Solar Panel Controller
This is an essential component especially for home solar panels that are rated over 100 watts. It protects the battery from overcharging and the photovoltaic solar panels from being damaged by reverse flow of current. Some photovoltaic solar panels charge controllers have a low charge disconnect circuit. This circuit is worth having as it protects the battery from complete discharge which can ruin it.
There are several of them. Some are suitable for 24V, 12V, or 6V photovoltaic solar panels systems. To get a suitable solar controller contact a home or marine solar panels expert if you are not sure which one to buy. We can help if you need one. These accessories affect the total solar panel cost.
A Solar Panel Deep Cycle Battery
You need a good deep cycle battery specially designed for photovoltaic solar panels to store the charge generated by the panel. Using normal batteries will not give you the optimal performance from your solar panel array.
A Solar Panel Inverters
These are mainly pure sine-wave and modified sine wave inverters designed for use with photovoltaic solar panels systems. Depending on the AC electronic equipment and appliances you have, you will buy one or both. The pure sine-wave inverter is for sensitive or high power electrical equipment such as computers light bulbs. For general use, you may use the modified sine wave inverters.
Solar Panel Cables
You also need cables to connect your photovoltaic panels to your power distribution unit. It must be a standard cable that has minimal internal resistance. Otherwise you will lose some of the generated electricity as heat energy. Generally, when current encounters internal resistance in a cable, it gets converted to heat. The heat is then dissipated by the cable through radiation. To get the best cables, buy the cables for your photovoltaic solar panels system from a trusted supplier.
How to Install Solar Panels
To best maximize the performance of your solar panel kit, the system should be matched, sited and properly installed, and maintained. There are a number of factors that should be considered for this to happen.These are:
- How much sun is available all year round (solar energy source).
- Do you want to connect photovoltaic solar panels system to the grid?
- What are the electrical energy needs of your home or business?
- Where will the solar panel system be installed and how much space will be needed (solar panel system sitting).
- What safety measures do you need to have in place to protect your photovoltaic solar panels installation?
Who Should Install Solar Panel System?
The solar panel installation and connections should be carried out by a professional who has had previous experience. You can also do it if you strictly follow the installation guide. The connection of these systems to the local utility power grid is unique and should only be done by experienced professionals.
Otherwise, if you may accidentally damage your photovoltaic solar panels or get an electric shock. A new photovoltaic solar panels company should not be eliminated because it does not have prior experience with a photovoltaic solar panels system. However, its staff must be professional and knowledgeable. They should be able to guarantee that they will do a proper job installing the solar panels.
Why Choose Experienced Solar Panel Installers
Experience gives any company an added advantage on issues such as getting permits for solar panel installations. Companies are also better placed to get the latest information on local authority codes and regulations. Experienced companies know how to best deal with customers and how to successfully complete a job.
The solar panel installation company should have all the proper licenses and installation permits. To get this information, you should contact your state’s electrical license board database. Other requirements include general licenses and trade licenses. Those must show that the technicians are conversant with solar panels or other Photo Voltaic Systems and they are authorized to install them.
Verify With Local Authorities
You should also contact your state electrical board to find out if the contractor has any pending cases, complaints or judgments against them. You may contact the city or county authority to find how to evaluate the contractor. Due diligence is key here, just like any project that is regulated, you need to do proper research and consultation. Otherwise your photovoltaic solar panels installation may not be done properly.
How Much Does One Solar Panel Cost and Factors that affect Installation
It is important that you get bids for any project you intend to carry out including installation of solar panels. Keep in mind that each bid must be evaluated on the same basis with the others. A roof mounted photovoltaic solar panels system for example will have different requirements to a ground mounted solar panel system.
The bids should indicate the energy estimates from the solar panel system throughout different seasons. The energy estimates should be in Kilo-Watt-hours and measured after the conversion from DC to AC at the inverter.
A good practice is to ask for the average annual output of each solar panel kit and compare it with the solar panel’s ratings. This will take care of daily variance that is bound to be affected by cloud cover, location of your home, season, and year.
Cost Of Solar Panels per Square Foot and Cost Variation
Do not expect an exact figure; however, they should give a variance of at least 20%. The total cost should cover all installation costs. That includes an indoor solar panel unit setup and commissioning, connection to grid (if you asked for this option), sales tax, permitting, and warranty.
Evaluate the company and ask yourself if they are willing to stand behind their solar panel warranty for two years. The warranties will include manufacturer warranties, labor-and-parts written installation warranty and other warranties that a solar rebate program may require or entitle you to. Some installer may offer longer warranties for their solar panels.
Cost Of Solar Panels per Square Foot and watt over the years
Grid-Tie versus Off-Grid Solar Panel Installations
These photovoltaic solar panels are most popular in remote locations that are not connected to utility power lines. They generate power that can be used as DC power of converted to AC power. The DC power is most preferred when powering telecommunication gear, boats, farm equipment and recreational vehicles.
It is less expensive to produce and use DC current from a solar panel than AC current. Conversion from DC to AC is always accompanied by some power losses. These installations use a special battery designed for use with solar panels to store electric energy for use during periods of weak or no sunlight.
Grid-tie solar installations
These are photovoltaic solar panels installations that you connect to utility power lines. When the home or business has a surplus production, the extra supply is injected to the electrical grid and the owner gets credits. When the solar panels are not producing any power, the home or business draws power from the electrical grid.
The credits are then deducted depending on how much power is drawn. This system is referred to as “net-metering.” A bidirectional meter is used to achieve this process. These photovoltaic solar panels systems also use batteries to ensure continued power supply when the power from the grid fails. When the grid power is restored, the normal net-metering continues.
Maintenance of the Solar Panel System
Just like any other system, routine maintenance is vital for it to last and serve you for the projected 30 year period. During this time, some of the components will need to be serviced or replaced entirely. Failure to do so will shorten the lifespan of the entire home or marine solar panels system. You may choose to personally service the solar panel system if you are a do-it-yourself person.
If that is not an option for you, then you may need to hire a professional to service the photovoltaic solar panels for you. There are times the system may experience a major failure or problem. In such instances, you may also be forced to contact a professional for proper advise, servicing and restoration.
Matching Solar Panel With Your Electric Equipment
You should properly estimate the size of your electrical energy needs. That estimate should also cater for the extra electrical load that appliance and devices need when you switch them on. Once you have the correct estimate of your energy needs, you need to buy a photovoltaic solar panel kit that matches or exceeds your electrical energy needs.
The first step is to consider your current energy needs that you must meet. You can do this by working with your home solar panel Installation service provider. They will survey your home or ask your questions to help them to calculate your home’s power consumption. This consumption is measured in kilowatt-hours.
Electrical Energy Calculation
Basically, you take the equipment’s rating in watts, and divide it by 1000. Multiply the result by the number of hours the equipment will be in use each day.
You do that for each equipment and sum up them up, and then double it. That will be the total power consumption per day in kilowatt-hours that your solar panel kit should be able to provide. You double the estimate to take care of the high energy needs during peak usage and when you start appliances. That will allow you to supply your home with all its electrical needs from your photovoltaic solar panels system. You will not have to switch some appliances off to start or operate others.
Your previous utility power bills are an important source of this information. You can compare them with your calculation to get an accurate estimate of your power needs. You should then install several solar panels to cover any energy consumption spikes.
Other factors that influence the size of your PV Solar Panel installation include:
- The solar panel’s sunlight to electricity conversion efficiency
- Length of daylight in your location
- Other sources of electricity such wind turbines or fossil generators
- The system’s tilt or orientation towards the sun
Most solar panel systems that manufacturers rate between 1 Kilowatt and 5 kilowatts can meet most of the energy needs of a small business or home. Manufacturers base their rating on a solar radiation of 1,000W per Square Meter, and an operating temperature of 25 degrees Celsius.
Solar Panel Orientation on the Roof
The way the photovoltaic solar panel faces the sun affects the angle at which the rays fall on the solar cells. This in turn affects the solar energy they receive. In the northern hemisphere, the best orientation is the true south.
In this position, the solar panel modules can face up to 45 degrees west or east without affecting the amount of solar energy they receive. There is an option to have a tracking mount installation that allows follows the sun to maximize exposure.
Solar Panel Tilt
The best tilt to have is that of your location’s latitude. However, you should have no problem if you fixed your PV flat on an angled roof. Moreover, the installation of the solar panel has to factor in the tilt of the roof if the builders angled it at an angle that is less than your location’s latitude. The perfect solar panel Tilt ensures that the Solar cells receive maximum sunshine exposure.
How Much Does One Solar Panel Cost- Financial Incentives Programs
In most countries, when you buy and install PV panels, you qualify for some kind of Financial incentives Programs such as residential tax incentive or rebates. Within the US for example, a good chunk of the installation costs is offset by the federal tax exemptions.
In some locations it can be as much as 60% while in others, it can be around 10% of the total photovoltaic solar panels cost. More information of the saving you can make is available at: Residential Renewable Energy Tax Credit.
There are also places where there are feed-in tariffs for solar panel installations. These allow homeowners to get compensated for the energy they contribute to the national grid using renewable energy sources. Some incentive clean energy programs pay home owners with PV systems a substantially higher rate than they charge them for connecting to the grid.
It is a good program because one sells at a higher price the power they produce, and buys at a lower price the little that they need during peak hours. Some financial institutions that finance mortgages add the cost of solar panel installation into the mortgage. Others offer special terms and rates to finance the photo-voltaic solar panels system’s installation.
Solar Panel System Payback Period Breakdown
The main reason or incentive for installing solar panel systems is either environmental or economic. Just like any other home improvement project, home solar panel installations offer a return on investment.
To establish your Payback Period Breakdown, You need to know the average sunlight hours for your location, the total installation cost per watt of the photovoltaic solar panels system, and the electricity cost per kWh in your area. You then need to calculate the savings you will be making each month.
These will be equal to the difference of what you used to pay to the utility power company and what you are paying them now, if any. You then take the total cost of solar panel investment you made, divide it by that amount you are saving to get the number of months you will need to recover your investment.
Solar Panel ROI Example
That is it when it comes to installation costs. You may need to factor in inflation; your accountant can help you out on that. For example, if you are saving $0.40 every month, and your total solar panel cost was $40. It could take you about 8 to 9 years to regain your investment. That would be your payback period for your home or marine solar panels.
Home and Marine Solar Panels
The total cost of solar panel installation has dropped by over 75% since 2010 because of government subsidies and the outsourcing of the production costs overseas. By the end of 2016, solar and wind energy accounted for 10% of the total energy used in the United States. That means it is now more rewarding to invest in photovoltaic solar panels than it was over 16 years ago. The number of professionals that offer solar panel installations are more today than there was in the past.
The solar panel installation experts are there to meet the increased demand of people who are opting to install solar power at their homes and business. Unlike wind power that is quite unpredictable, photovoltaic solar panels guarantee you sufficient energy as long as there is sunshine. Therefore if you experience lost of sunshine during some months of the year, you could save make huge savings at such times. If you have a boat or RV, then you will not need to head home to recharge your battery bank. Overall, photovoltaic solar panels give your greater independence from the utility company.
