Answer: Solar power is harness through the use of photo-voltaic cells or popularly known as solar cells attached in a panel in rows. Once sunlight hits these solar cells, a transformation occurs which convert sunlight through the solar cells to electrical power which is usually stored. It helps in most electrical appliance in your house hold, It powers emergency phone you will find in freeways, Some industrial companies has it to power their warehouse and office equipment and some manufacturing companies. Powers some experimental cars to travel without gasoline which was documented to travel from coast to coast in the US. Some handheld calculators, car fan coolers and watches are powered by these solar cells. Some Industrial farms also uses them for their electrical power need.
Since this form of alternative energy has been with us more than 20 years, its potential to be the primary source of electrical energy was not that promising.
The difference between solar power vs conventional power generation
1,Solar power is a clean form of electrical power generation. Cleaner than the conventional power generation.
2. Solar power has limited power potential compared to a vastly huge power potential of the conventional
3. Solar power is environmentally friendly while conventional has the potential to be destructive like the nuclear powered plants.
4. Electrical power from solar energy can be stored by a rechargeable battery while conventional is not.

Answer: Some Facts Power From The Sun:
• Solar power is a viable and renewable source of energy. Its appearance certainly is restricted but it is at least consistent in its delivery pattern.
• Solar power is non polluting, meaning its use keeps our breathable air free from carbon dioxide and heaven knows what else is out there damaging our bodies in the greenhouse gas and emissions soup we inhale.
• We can use solar power to keep our water heated, dry our clothing, heat a swimming pool, keep attic fans operating, energize small appliance and electrical devices, power lights inside and out, we can even use it to power automobiles and numerous other uses.
• In 1990, the first solar powered aircraft flew across the United States only using solar energy.
• Solar power systems can be expensive and this is a drawback from their use in more areas though the prices are gradually decreasing as the technology is improving rapidly.
• You need a fairly big space to set up solar panels if you are hoping for the best efficiency ratings.
• The solar panels efficiency has a lot to do where you are located geographically [Arizona as opposed to the Pacific Northwest or the Northeastern states].
• The good news is once the solar array is installed, your costs are negligible at best and they begin to quickly return your investment. The sunshine is free!
• Thanks to net metering, if your solar power system generates more electric power than you are consuming, the utility grid company will pay you for your additional power.
• The use of solar energy for your residence means you are independent from the burden of your municipal utility. You no longer are dependent on foreign sources of power or domestic for that matter. They can raise their rates all they like and you will not feel a thing.
• When you install a solar power unit, it is not necessary to connect with the gas or power company grid.
• Solar energy units do not produce at night or when it is overcast or pollution is thick, covering up the sun.
• There are ways around that as well if you have a battery arrangement in place as a back up and power storage unit. This means when there is no sun available you can still use stored power for your home.
• Solar power systems can be installed in very remote regions.
• If the power goes out you will still have electricity and with power companies increasingly initiating “brown outs”, you will no longer be resetting clocks and restoring lost computer information.
• Solar power units are scalable so when you need more electricity you simply add more solar panels to your existing array.
• Solar panels do not make any noise when they do their job.
• Solar powered autos are a long way off for consumer use and commercialization. Same for air travel.
• Once you install your solar power system, it is pretty much build it and forget it since little maintenance is required – and they last a long time.
• Once again, it is vital to note that the technology for solar power is improving extremely quickly as the government becomes more involved with green energy solutions and private investment increases. Some very bright minds are researching and developing new ideas for solar energy.
This is only a partial list of some relevant facts about solar power in 2010. It is time we all educate ourselves about this alternate form of renewable energy as the oil reserves begin to dry up around the world.
Answer: Depending on where your located, rooftop solar can be extremely profitable. Owning your own system is the way to go if you can utilized the 30% Federal Tax and the accelerated depreciation. In Rhode Island for example you can expect to get your money back in your pocket in under 5 years, on top of that you will continue to generate residual cash flow for the next 20 plus years. Lets run the numbers real quick, to do so we will analyze a project I developed located in Middletown Rhode Island.
This 108 kilowatt solar array is compromised of over 300 photo-voltaic solar panels producing 140,000 kilo-watt hours annually . The upfront cost for this system was $270,000 , heres how it all makes sense .
1. Federal Tax Credit (It is important that you have a tax basis that can absorb the credits) The Tax credit is 30 percent of the upfront cost.
• Upfront Cost $270,000
• (Fed Tax Cred) -$81,000
• Balance $189,000
2. Rhode Island State Cash Grant ( each state has its own incentives RI issues cash grants based on the system size, this project qualified for a $114,000 dollar cash grant which equates to 42 percent of the project cost.)
• Cost After Tax Credit $189,000
• RI Cash Grant -$114,000
• Balance $ 75,000
Right off the bat as soon as the solar array is interconnected to the grid 73% of the cost was recouped. (This was only possible because the client was able to utilize the federal tax credits during the first year.)
3. Energy Income This array will produce 140,000 kWh per year. Rhode Island’s utility company National Grid issues energy credits of .14 cents per kWh. That equates to $19 ,600 dollars per year. These energy credits which are basically a gift card to National Grid, are sold at a 15 percent discount to the property owners tenants since the power must be utilized on site for this particular project, netting the owner $16,660 per year.
With just the energy income alone it would take 4 and a half years to pay off the the remaining $75,000.
4. Accelerated Depreciation the accelerated depreciation is calculated by taking 85% percent of the upfront cost to find your basis the multiply by your tax rate which in this case was 45% percent so…
upfront cost $270,000 X .85 = $229,500
229,500 X .45 = $103,275
The total depreciation for this project was $103,275, this is spread out over a 5 year period. It is important to note that the depreciation isn't prorated equally thru out the 5 years and should be discussed with an accountant.
5. Solar Renewable Energy Credits Rhode Island solar arrays are also eligible for state issued energy credits which trade for about $20 bucks per REC. RECs are generated for every 1000 kWh the solar array produces. This array produces 140 RECs annually with a cash value of $2,800
Thru out the 5 various forms of revenue this array will be completely paid off in under 4 years and will generate cash flows of $19,460 per year after your original investment is back in your pocket.
Not all states are this lucrative for solar but its definitely worth looking into,
Hope this helps!
Answer: Hi, here are some considerations. If you invest properly in solar power today and take advantage of any grants and tax incentives, even if your electric rates do not go up as they are forecast too, you will get your money back over time, well within the lifetime of the equipment, and sooner if there is a rate increase in the future. There are also enviromental benefits. At one time there was an argument that a solar panel will never produce as much power as was used to manufacture it. First of all, this is not correct. The, "Embodied Energy," in a solar panel is earned back in 2 - 6 years, depending on the type panel, where the raw materials were shipped from, and how it was installed and used in the end. Most panels are warrantied to last at least 25 years, and most last much longer than that. But the argument is not important anyway. We have been living with electricity for over a century now, so it isn't going away anytime soon. The question is, "What is the best way to produce it?" If you build a panel, and put it along side a similar sized natural gas fired turbine generator for example, which earns back its embodied energy sooner? The answer is the gas turbine never does, because once you build it, ship it and install it, you now have to feed it natural gas for the rest of its life, so it keeps on digging itself a deeper and deeper embodied energy hole that it can never crawl out of. At least the panel has a chance to get even environmentally. So manufacturing and using solar panels in the end releases less pollution into our environment.
There are also mechanical and political benefits. We all know after the oil embargo of 1973, and the gulf war what it means for our country to rely on foreign oil. Wouldn't it be nice if we only shipped in 20% of our energy instead of 60% the next time something like that happens? Our home has been powered by the wind and sun for years now, but we still remain connected to the electric grid. Last year alone there were two power failures in our county that lasted about a half day each. In both cases, we were not aware of them because our solar array kept on feeding the house. It's difficult to put a price tag on something like that. Did you know that there are over 100,000 homes and businesses in the United States alone that use some level of solar power to operate their electrical devices, that's good news.
Beyond the mechanical, political and environmental benefits however, lies a less obvious benefit, the social benefit. Right now we pump oil out of the ground, and mine for coal. The process of getting those materials to market involves shipping, military escorts and other activities that use up a good portion of that energy as well as putting lives at risk. Jobs in alternative power are higher tech than jobs in coal mining, oil drilling and shipping, and there are more of them. Using more alternative power would require us to put more people to work, and increase our education base because the work involved requires certain skills. I would personally like to take all those people out of the coal mines, send them to school and put them to work building solar panels. Nobody would have to die again in one of those dark holes in the ground trying to find food for our hungry power plants. They could work on a factory floor where they would not be exposed to coal dust, radon and other toxins and dangers. Most of our solar and wind resources are spread pretty evenly over the middle half of our globe, so everyone has access. This puts people in Bogota on a more equal footing with people in Boca Raton by giving them access to electricity, heat and clean water, and the education to use the solar, wind and biomass resources that provide those things. Oil, coal and natural gas is generally piled up in a few places, such as Russia and the Middle East. This gives those countries and the richer governments that rule them more horse power in bargaining for the other resources of our planet. These are the things that wars are made of.
There are other reasons, but I think you get the picture. For us, solar energy has become something of a hobby It will probably never save us any real money, utility power in most places is really very inexpensive, but it's a little like growing your own tomatoes. It's usually cheaper to buy them at the grocery, but lots of people go to the work and expense to maintain a garden instead. We just grow electrons in ours. If you really want to learn more about the subject, there are some great sources to look into, I will list some below. Good luck, and take care,
Answer: The solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity throughout the day. A discreetly placed inverter converts the DC electricity
into alternating current (AC) electricity, which is what your business utilizes. When your solar power system produces more power than you need, it feeds the power back into the electricity grid.
Answer: Today, solar costs less than traditional electricity in many markets. We can install your system with no upfront cost, and you can pay less for clean, abundant solar energy than you do to your utility company.
Answer: Yes, all our systems are connected to the utility grid. During the day, your property will draw energy from the solar system and feed any excess energy back to the grid. At night, you’ll continue to draw energy from the grid as you do now.
