Solar Panels Placed on Many Rooftops These Days

 If you have made the decision or are thinking about making the decision to go solar, then you may be wondering - how does sunlight actually get turned into electricity? You may have other questions too, such as will your solar panels work on cloudy days, and will your panels work at night via moonlight, which, after all, is reflected sunlight? To find out the answer to these questions and a few more, please read on. 

Q. How does solar power work?

The sun may be around 93,000,000 million miles away, but it is still a very powerful source of energy, and if you've even been sunburnt, you'll know just how powerful! Solar energy came about thanks to a chance discovery. While studying light, the French scientist Alexandre Edmond Becquerel noticed that when certain materials, such as silicon, absorbed light, they “knocked” electrons loose. From this observation, he perfected the photovoltaic (PV) cell, which was a device containing an electric field that made these “knocked” electrons flow in a certain direction, hence creating an electric current. Modern-day PV cells still use the same principle.

Q. Do solar panels work on cloudy days?

Yes, but less efficiently. The brighter the day, the more light arrives at the PV cells, and the greater the number of electrons that are sent flowing. If the sun is blocked by cloud, less light reaches the cells, and less electricity is produced. On a dull day, a panel will only produce between 10 and 25 percent of the electricity it can produce on a clear day.

Q. Can solar panels work by moonlight?

No, the sunlight reflected by the moon is too weak to generate any solar power. Your system will still power or at least partially power your home at night, as most systems come with a battery that stores some of the electricity generated during the day to be used at night.

Q. How long do solar panels last?

That depends on the manufacturer. Most PV solar panels have a lifespan of around 25 years, but can run for 40 years and beyond.

Q. Is there a need to keep solar panels clean?

Yes, there is. PV cells only work if they receive direct sunlight, so anything that is blocking them will prevent them from generating any electricity. This could be leaves and other natural debris, bird faeces, and of course in winter if your roof is covered in snow, your panels will not work. In general terms, it is probably worth having your solar panels cleaned once every couple of years or so.

Q. How much electricity does a solar panel typically produce?

That depends upon the kind of system you install. As a general rule, each 1kW of solar panels produces 850kWh of power in a year. Therefore, if you have a 4kW system, you will generate 3,400kWh of electricity annually, which is roughly worth about $400, and is enough to power nine big screen plasma TVs for a whole year.

Hopefully, that should have answered some questions you may have had about solar energy. If you wish to get more info, you can visit the Department of Energy Solar Website , which have plenty of information and resources

Can Switching to Solar Panels Save Me Money ?

Switching to Solar Energy Can Save You Big

There are plenty of reasons why using solar power is a great idea, especially when it comes to environmental issues, as solar energy is one of the cleanest forms of energy there is, with little in the way of the harmful emissions associated with other, traditional forms of energy such as gas and electricity.

One of the main reasons people can appear a little reluctant in adopting solar power as an alternative power source within their home is the amount of money they think it will cost to install a solar energy system. The truth is, there is more than one way to obtain a solar energy system, and you can even have a solar energy system installed in your home for no cost to yourself whatsoever!


Solar – the free energy source

The biggest advantage when it comes to solar energy is that solar energy systems are powered by the sun, and of course, sunlight is free. Solar energy systems still draw power from the sun even on cloudy days – your house does not have to be in direct sunlight all day in order to benefit from solar, and solar energy systems 'store' power during the day, so don't think all your appliances will be useless once the sun goes down. It is possible to install enough solar panels on your roof so your home is completely powered by solar energy – meaning that you pay utility companies absolutely nothing!

There are other financial aspects to take into consideration if you're thinking about converting to solar energy. Some utility companies will buy any surplus energy your system generates but which you yourselves do not use. All states in the US also now have so-called solar incentives, which includes tax credits and other incentives that are offered to people to hopefully persuade them to convert to solar energy.

Solar is a great long-term investment

According to figures released by the Energy Department, converting to solar would save you money in the long term in 45 out of the 51 US States (the unlucky ones being South Dakota, Idaho, Arkansas, Indiana, North Dakota and Mississippi). If you are lucky enough to live in Hawaii, you will save nearly 24 percent on your fuel bills over 25 years, and States such as California, New York, Colorado and New Jersey will all save 10 percent. If that doesn't sound too great, then consider that the same amount invested in 30-Year US Treasury Bonds over that time would only generate a return of under 4 percent!

If you don't want to pay for your solar panels, you can always lease them instead. This means a company will 'lease' your roof-space off you so they can install panels there. They will then sell you the power that the panels produce at a 'locked-in' fixed rate that's cheaper than mains electricity, but you would not receive the tax breaks and incentives that paying for your own installation brings.

Switching to solar power will definitely save you money, just how and how much is up to you. If you're still unsure about going solar, why not head to the Cost of Solar website and use their handy 'Solar Saving Calculator' to find out just how much money you could save?

Why Use Solar Power These Days ?

Solar Power Usage is on the Rise

One thing is clear now, global warming is a very real aspect of our lives. The latest report from the Intergovernmental Panel on Climate Change confirms that average global temperatures have risen 0.85 degrees Celsius since the Industrial Revolution. That may not sound like a lot, but even the smallest rise in average temperatures across the globe causes significant changes to our planet's climate, such as rising water levels and devastating weather events.

If we want to leave the planet in a fit state for future generations, then we need to clean up our act, environmentally-speaking, but even if you are not overly concerned about environmental matters, there are plenty of reasons why you should consider using solar power.


It's free and it's clean

Solar energy systems work by converting sunlight into power for your home. Sunlight is, of course, free, and solar energy systems work whenever the sun is in the sky, even if there is a layer of cloud cover. Solar energy can be used to power all your domestic devices, from an electric toothbrush to a widescreen TV. It also has virtually no impact on climate change, unlike other energy sources which often result in unwanted, harmful emissions.


It's almost infinitely renewable

Because solar power takes its energy from the sun, there's very little chance that the sun will cease being a source of energy – for the next one billion years at least. Other typical forms of energy, such as coal, gas and oil, will one day run out.


It will both save you and earn you money

The power that is created by a solar energy system is converted into electricity, and that electricity is then used to power devices within your home. As a result you will need to use a lot less energy from utility companies, especially if you use less gas-powered appliances within your home – particularly when heating and cooling, as nearly half the energy used in a typical US home is used in this manner – and use electric-powered ones instead.

In some states you can obtain tax credit for installing a renewable-energy system. You may also be able to claim incentives from your utility company, as some companies will buy any energy you create but do not use in your home off of you.


Your home will be worth more

Energy-efficient homes are becoming more attractive, and as austerity measures continue, people are seeking energy-efficient homes in a bid to reduce their utility bills and their overall monthly spend. The US Department of Housing and Urban Development estimates that for every $100 that a house is able to save in annual utility bills, and additional $2.000 is added to the house's value.

If you would like to know more about solar energy, then please feel free to stick around at Solar Nation.org. By adopting solar energy, you will be achieving many short term and long term goals. Short term in the savings you will make, and long term in the less damage you will cause to the Earth's climate. People from our planet's future will no doubt thank you for your decision.

Solar Panels Industry Review and the Future

Solar panels are used to generate electricity using solar energy. Now, you must be thinking what is solar energy? Solar means sun and the energy generated by the sun is called solar energy. The mechanism of solar panel is very simple. The panel has photovoltaic cells, which emits current when direct sunlight falls on it. This current is then stored into the battery and then converted into AC by the inverter before being used.

If you are planning to install a solar panel then a few questions might come across in your mind like where can I buy it, what type of panel will be perfect for my usage, how do I install it etc. Fortunately, the above questions can be dealt easily because you will find many stores in the market that specialize in manufacturing panels. They also have experts who will help you select the right one and then install it so that the process is easier for you. But, how will you know that the shop or company from where you have bought the panel sells quality product?

Online panel review is the best way of deciding where and what to buy. Most of the people love sharing their good or bad experience about using a product. Thus, you can visit personal websites of different companies dealing in solar panel and read what they have to tell about the product. You might come across 100’s of business dealing with the same kind of product and visiting them one by one can be time consuming. You can select the reputed ones and then collect information about them.

You might get a mixed response about the solar panels in the reviews so the other two places where you can find solar panel review are:

1. The buyers guide is the best place where you can know about the panel. Here you will find all the required specification which includes efficiency, cost, warranty period, output power and the watt that the panel can emit etc. When you read the specification of different companies you will easily be able to compare and take decision.

2. You can also visit websites and see how it is rated by the users
