The Institute for Energy Research is a not-for-profit organization that conducts intensive research and analysis on the functions, operations, and government regulation of global energy markets. President Obama subsidized solar and other renewable energy in the United States with taxpayer money to the tune of $39 billion per year on average for the past 5 years.
The Taxpayers Protection Alliance produced a report highlighting information from various studies on the U.S. States also have also heavily subsidized the solar industry by offering tax breaks and 538 rebate programs. The 2009 stimulus package provided an estimated $51 billion for renewable energy projects, including funding for failed solar energy companies like Solyndra and Abound Solar. You’re here because you probably know that installing solar panels in your home can save on your energy bill. Solar power technology emanates from the idea that the sun’s light energy can be trapped and harnessed as electrical energy via a combination of special panels, batteries and a DC to AC inverter. In such a project, solar panels take the central axle on which the wheels of this green technology run. As mentioned earlier, solar panels are primary powerhouses in the generation of this kind of green energy. A single panel contains millions of interconnected photovoltaic modules packed closely and protected by a transparent glass panel.
The current generated, which typically flows as a result of the potential difference between two terminals, constitutes the bulk of the electrical energy harnessed. So in a nutshell, the array of photovoltaic modules packed in the solar panel traps the light and converts it to electricity.
Most people may not know this, but solar panels and the solar power technology has been with us since the 1950s. Fortunately as a consequence of the advancement of technology, the cost of solar panels has decreased tremendously and are now readily available in most hardware and roofing stores all over the world. Even better, you can order yours online from reputable dealers or even big box stores like Home Depot. The specs are mainly based on the efficiency tests of the panel and the construction material. If you need solar panels for your home, then anything with a 5%-15% efficiency will comfortably fit your bill.
On the same note, make sure you inquire on warranty period issued for the panel you’re going to purchase.
The number of solar panels you might need for your home is directly tied to your average monthly power consumption. The other factor to put into consideration is the amount of consumption you’re looking to cover using the solar panels installation. Lastly, the average number of peak sunshine hours per day in your area should also be factored in when calculating the ideal number of panels required.
In short, all the three factors have to be considered before you decide how many panels you’re going to purchase.
For example, If you go completely off the grid and adopt a solar power project for your home, then your installation is likely to be more complex than if you were looking at a backup or partial power plan. Considering all these factors, with the help of an experienced electrical contractor, the project could take anywhere between 5 days and two weeks to complete ( depending on its scale and the manpower available). That said, it may take a month of fine-tuning & minor tweaks before a fully fledged solar-panel power project can comfortably generate 100% of the power consumed by a large-sized residence.
I would love this savings however we live in a town that doesn’t have many installers.
Thierry, the leasing of the panels (and then I am going to BUY out at the end of the seven years) had nothing to do with the value of my home because I will own the panels when the lease is up.
I’d like to experiment the cost effectiveness of solar power calimed in several articles I read over the net.
In the coming week I am checking the stores in town dealing with sales of solar power components.
Solar energy: radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. The spectrum of solar light at the Earth’s surface is mostly spread across the visible and infrared (IR) ranges with a small part in the near-ultraviolet range.
The visible and near-ultraviolet components of solar light are converted to the electricity and IR only heats solar cells. Modern active solar water systems have electronic controllers see Figure bellow (b,c,d))  that offer a wide-range of functionality, such as the modification of settings that control the system, interaction with a backup electric or gas-driven water heater, calculation and logging of the energy saved by a system, safety functions, remote access, and various informative displays, such as temperature readings. Hivatec is a Canada based company which embodies the Canadian standard of quality and service. At the end of 2013, Pickering Energy Solutions celebrates the end of its second year by achieving another milestone—our installed systems have generated 100 MWh of power production! It has also saved the mining, cleaning, transportation and combustion of 53.5 tons of coal, and offset the emission of 104 tons of CO2 into the atmosphere from a coal-fired power plant. We look forward to 2014 with optimism, anticipating new opportunities to provide renewable energy installations within the Mid-Ohio Valley.

Here you have a list of opinions about Solar power and you can also give us your opinion about it.
You will see other people's opinions about Solar power and you will find out what the others say about it. Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).
Photovoltaics were initially, and still are, used as a source of renewable power for small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array. In the image below, you can see a graph with the evolution of the times that people look for Solar power. Thanks to this graph, we can see the interest Solar power has and the evolution of its popularity. You can leave your opinion about Solar power here as well as read the comments and opinions from other people about the topic. Every device we use in our day-to-day life such as mobile phone, computer, induction cookers, washing machines, vacuum cleaners, etc., requires electric power supply. Solar and wind hybrid power systems are designed using solar panels and small wind turbine generators for generating electricity. To better understand the working of solar wind hybrid system, we must know the working of solar energy system and wind energy system. Solar energy is one of the major renewable energy resources that can be used for different applications, such as solar power generation, solar water heaters, solar calculators, solar chargers, solar lamps, and so on. A solar panel is made up of solar cells or solar photovoltaic cells, and is used for converting solar energy into electrical energy. But, in fact, the solar panels output is affected by number of factors like climate, panel orientation to the sun, sun light intensity, the presence of  sunlight duration, and so on. There are advanced technologies for improving the output of solar panels by using sun-tracking solar panel arrangement, that rotates the solar panel so as to get more light from the sun. We must also know the working of the solar cells to understand how the solar panels convert solar energy into electrical energy. Solar photovoltaic cell consists of a P-type of silicon layer that is placed in contact with an N-type silicon layer. Generally solar panel open circuit voltage (voltage when battery is not connected) is higher than solar panel rated voltage.


Solar photovoltaic (SPV) effect is a process to convert solar energy into DC electricity using an array of solar panels. Wind energy is also one of the renewable energy resources that can be used for generating electrical energy with wind turbines coupled with generators. Large wind turbines are made to rotate with the blowing wind and accordingly electricity can be generated. Wind turbine can be defined as a fan consisting of 3 blades that rotate due to blowing wind such that the axis of rotation must be aligned with the direction of blowing wind. An electrical generator is coupled with wind turbine; hence, it is named as wind turbine generator. Squirrel cage induction generator is directly connected to the power grid or to feed AC loads or DC loads using appropriate converters.
A wound rotor induction generator, which is connected to power grid or batteries whose speed can be adjusted using rheostats for maintaining required outputs.
A double fed induction generator, which is connected to power grid whose speed can be controlled using back-to-back converters. Consider DFIG double fed induction generator with 3-phase wound rotor and 3-phase wound stator. Thus, as shown in the above solar wind hybrid system figure the electric power generated from solar energy system and wind energy system can be used for charging the batteries or for feeding DC loads or we can use the entire power for feeding AC loads. Twenty states have personal tax credits related to solar products, 18 states have corporate tax credit and deduction programs, and 14 states and Puerto Rico offer taxpayer-funded grants to support solar electricity. The Obama Administration gave Solyndra a $535 million loan guarantee to manufacture solar panels, but the company had to file for bankruptcy in 2011.
They form the primary transducers that convert the light energy into useful electrical power.
The panels, which come in different sizes and specifications, convert the sun’s short-wave radiation to electrical energy. The photovoltaic cells used in most solar panels today are basically miniature photoemissive materials (emits electrons when a ray of light of a given wavelength shines on them). The power produced can be used directly or first taken through a unit of batteries and inverters for a more consistent supply. Back then, the panels were only a reserve for costly scientific explorations, and they were also hardly affordable.
Even though solar panels with higher efficiency are desirable, you may want to avoid buying anything with a more than a 20% efficiency rate. Your monthly consumption is simply the amount your home utilizes on an average day then multiplied by 30 or 31 (days). In case you do not have an energy meter, you can still use your past electric bills as a worthy estimate. You will need more panels for a 100% grid take-over than you would for a sizable occasional backup power plan.
In this case, if you need to generate 100% of home’s power consumption using solar panels you might require four solar panels rated at 200Watts each. Additionally, it depends on whether you want to do-it-yourself (DIY) or planning on hiring an installation contractor. So I am leasing them through the installation company for $45 per month for 7 years and I will have to pay off about $7,000 at that time. When my house was reappraised, the adjuster said the addition of the panels is a $45,000 upgrade and the appraisal reflected as such. An active system uses an electric pump to circulate the heat-transfer fluid; a passive system has no pump and they have extremely low or no maintenance. They are cheaper than the indirect system, but can have drawbacks – they have no overheat or freeze protection. Though slightly more expensive, indirect systems offer freeze protection and typically offer overheat protection as well. Our many years of experience allow us to offer simple and effective solutions to your needs. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.
They are an important and relatively inexpensive source of electrical energy where grid power is inconvenient, unreasonably expensive to connect, or simply unavailable. The International Energy Agency expects solar photovoltaics and concentrated solar power to contribute about 16 and 11 percent of worldwide demand, respectively, with most installations being deployed in China and India.
The 392 MW Ivanpah installation is the largest concentrating solar power plant in the world, located in the Mojave Desert of California.
And below it, you can see how many pieces of news have been created about Solar power in the last years. Thus, the advancement in technology is increasing the electrical and electronic appliances usage – which, in turn – is increasing the power demand. Solar power system can be defined as the system that uses solar energy for power generation with solar panels.
There are various advantages of solar energy usage in electric power generation including low pollution, cost-effective power generation (neglecting installation cost), maintenance free power system, etc. These solar panels are designed with different output ratings like 5 watts, 10 watts, 20 watts, 100 watts etc. The quality of wire must be good and have sufficient gauge for handling the current to ensure proper battery charging. Solar cells or solar photovoltaic cells are the devices that are used for converting solar energy into electrical energy by utilizing the photovoltaic effect. Due, to this combination a charge on either side of the P-N junction is created and this charge creates an electric field. For example, consider a 12 volt solar panel giving an output voltage of around 20 volts in bright sun light- but, whenever a battery is connected to the solar panel, then the voltage drops to 14-15 volts.
This, DC electricity can be stored in batteries shown in the figure or can be used to feed DC loads directly or can be used to feed AC loads using an inverter that turns DC electricity into 120-volt AC electricity. There are various advantages of wind energy, such as wind turbines power generation, for mechanical power with windmills, for pumping water using wind pumps, and so on.
The minimum wind speed required for connecting the generator to the power grid is called as cut in speed and maximum wind speed required for the generator for disconnecting the generator from the power grid is called as cut off speed. A gear box is used for converting energy from one device to another device using mechanical method; hence, it is termed as a high-precision mechanical system. There are different types of wind turbine generators and these wind turbine generators can be directly connected to the power grid or loads or batteries based on different criteria.
An AC current is induced in the rotor windings due to three phase AC signal fed to rotor windings. Hybrid solar wind charger is a practical project in which the electric power generated from solar energy and wind energy are used for charging the batteries. If yes, then share your answers, in addition, for designing interesting & innovative electrical and electronics projects on your own you can download our free eBook or you can approach us by posting your comments in the comment section below.
By connecting several distributed power sources, as well as electric utility network, a novel power supply network can be built, which is economically more efficient and environmentally more benign. On his trip to India, President Obama was hoping to bring back a deal similar to the one he made in China to peak the country’s carbon dioxide emissions by 2030.
Over the last 5 years, taxpayers spent over $150 billion on solar power and other renewable projects, financing grants, subsidizing tax credits, guaranteeing loans, and bailing out failed solar energy companies, according to the Brookings Institute.
The 538 different state and local green energy rebate programs are intended to reduce the final cost of products including solar water heaters and grid-connected rooftop solar panels. Abound Solar received a $400 million federal loan guarantee, but its product was defective, producing only a fraction of its intended wattage, with solar panels catching on fire.
Although like any major project you need to thoroughly research before deciding if solar power is right for you.


After inversion of this power to AC, it can be supplied throughout a building or home via a suitable electrical installation just like the standard grid supply.
Since they are interconnected, the electrons dissipated by the sunlight pool to form a larger stream now referred as an electrical current. To be safe, you might want to use the highest usage ever recorded on your monthly bills, just to leave room for a deviation allowance.
Again, if you want to live completely off the utility grid you will have to invest in a more sophisticated DC to AC power inverter unit.
This estimation is based on the fact that a simple mathematical calculation reveals that such a homeowner utilizes an average of 760 watts per day. All older buildings should be refitted for solar power and it just blows my mind that we could do this but who could or should pay?
On the upside my average bill is about $10-15 per month, my house was appraised at $45,000 more and my house is at 73 degrees every day all day. So yes basically the value did increase, I will own the panels and if I were to take any equity out of my house now I could take that $45,000. The total solar energy absorbed by Earth’s atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. A closed-loop system uses a heat-transfer fluid (water or diluted antifreeze, for example) to collect heat and a heat exchanger to transfer the heat to household water.
However, as the cost of solar electricity is falling, solar power is also increasingly being used even in grid-connected situations as a way to feed low-carbon energy into the grid. Other large CSP plants include the SEGS (354 MW) in the Mojave Desert of California, the Solnova Solar Power Station (150 MW) and the Andasol solar power station (150 MW), both in Spain. Thus, to meet the load demand, different techniques are used for electric power generation. The typical power generation capacities of solar wind hybrid systems are in the range from 1 kW to 10 kW.
The block diagram of solar wind hybrid system is shown in the figure in which the solar panels and wind turbine are used for power generation. Solar power system consists of three major blocks namely solar panels, solar photovoltaic cells, and batteries for storing energy. Thus, the electrons produced in the N-type material are passed to the battery through electrode and wire. These cells are used in many real-time applications such as railway signaling systems, street lighting systems, domestic lighting systems, and remote telecommunication systems. The holes in the P-type material accept the electrons but there are more electrons in the N-type material. This formation of electric field results in developing a diode like system that promotes the charge flow. There are different types of wind turbines, but the frequently used wind turbines are horizontal axis turbines and vertical axis turbines. Due to mechanical force produced from wind energy the rotor starts rotation and produces a magnetic field. The purpose of the study is to evaluate the influence of the extensive introduction of distributed power sources on the national electric power supply systems, through the use of a cluster of thousands of agent-type models. However, Prime Minister Narendra Modi rejected the President’s proposed global warming deal, realizing his priority should be to bring power to the hundreds of millions of Indians that lack access to electricity.[ii] India’s Prime Minister knows that it needs all forms of electricity generation, including coal, to accomplish this goal.
According to the Government Accountability Office, federal government support for solar energy is massive, with over 345 different federal initiatives covering over 1,500 projects in 20 federal agencies–the Pentagon has 63 solar programs, the highest among the agencies, followed by the Interior Department, with 37 programs and the Energy Department (DOE) with 34 solar programs.
If I were to get an electric car with all the rebates and money I save not paying for electricity I could drive the car for free.
They sent a rep to my house and I had to have two years of electric bills so they could figure an accurate average monthly use. The articles are rather technically overwhelming to me, though I read an enthusiast just do it the DIY way!!
The second reason is the pointless losses of solar energy – instead of being converted to electricity, the energy is lost to heat.
The two 550 MW solar farms, Topaz Solar Farm and Desert Sunlight Solar Farm in the United States, are the world’s largest photovoltaic power stations. Before discussing in brief about the solar and wind hybrid power system, we should know about solar power generation systems and wind-power generation systems. The electrical energy (DC power) generated using solar panels can be stored in batteries or can be used for supplying DC loads or can be used for inverter to feed AC loads.
From the battery, electrons reach p-type material, where these electrons and holes are combined. It is essential for designing the solar panel arrangement on the roof top for efficient usage and typically solar panels are arranged such that they face the East at an angle of 45 degree. So, with the influence of the solar energy, these electrons in the N-type material moves from N-type to P-type. This is called as drift current and the diffusion of electrons and holes is balanced by drift current. The speed of the rotor and frequency of AC signal applied to rotor windings are proportional to each other. The model integrates a household energy demand simulation model of bottom-up type, and an optimal operation model for distributed power sources based on stochastic dynamic programming. Solar power is the conversion of sunlight into electricity directly using photovoltaic (PV). IR makes a significant contribution to the solar spectrum – it is approximately half of all solar energy, and so it is important to filter it out.
Our filter allows one to take the normally useless heating energy and use it for more productive purposes. The combination of renewable energy sources can also be used for generating power called as hybrid power system. Hence, the solar panel connected to the battery behaves like another battery, and hence, is comparable to the two serially connected batteries. It is recommended to properly clean the surface of the solar panels for removing dust, moisture and also to reconnect the terminals. This drift current occurs in an area where mobile charge carriers are lacking and is called as the depletion zone or space charge region. This result of constant magnetic flux passing through stator windings produces AC current in the stator winding. PV is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. The thin water layer can circulated from our filter to the heat exchanger, where the water gives heat and comes back into the filter cooled.
As a special case, we will discuss about the working of solar-wind hybrid system in this article. Thus, during night time or in the darkness, these solar photovoltaic cells behave like reverse bias diodes. Due to variation of speed in wind speed there is chance of getting AC signal output with varying frequency.
Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material. So, by varying the frequency of input AC signal given to the rotor windings we can obtain AC output signal with constant frequency.
