A solar panel is a system that converts sunlight directly into electricity. Solar panels use a photovoltaic effect to convert energy from sunlight into direct current electrical energy which an inverter unit then changes into an alternating current for your home’s electrical circuits. It refers to a panel designed to absorb the sun’s rays as a source of energy for generating electricity or heating. Solar Panels make use of a renewable source of energy which is the sun to produce electricity.
Solar Panels are at their best when they are facing North, pointed directly at the sun, at an optimal angle and not obstructed by trees or shading. Solar Panels produce electricity only when sunlight falls on them which they convert into electricity without the use of a generator or any other mechanical moving part. Solar Panels also referred to as modules or photovoltaic system are made of several cells connected together and sandwiched between protective glass and a backing plate. Most industrial or commercial solar energy power plants use reflective mirrors to focus the rays of the sun to super-heat
fluids that in turn heat water to make steam for traditional steam-powered turbines. Also, Solar panels work best in an energy-efficient building. So, adding insulation and energy-efficient lighting, appliances, and windows is a great idea to reduce your home’s overall electricity use before you install a solar panel. You can improve the energy efficiency in your home and save up to 30% on your bills by turning off appliances, using the dishwasher and washing machine only when full, and purchasing energy-efficient appliances.
One major question that people ask when it comes to solar panels is “why should I use a solar panel?”. Solar technology is rapidly increasing, and people should begin to realize the importance of solar technology. There are numerous reasons that are of utmost benefit to you on why you should use solar panels. Let’s take a quick look at some of the reasons.
Environmental Sustainability: Solar panels are good, clean and pollution-free sources of energy. Unlike fuel and fossils and other harmful pollutants, solar panels generate energy through the sun which not only prevents you from inhaling all those harmful substances, but also benefits the environment. Global warming and climate change are major issues facing the world today, so with your contribution of assistance in using a solar panel, you can be part of thousands of other people interested in making the environment a conducive place to live in.
Financial Benefit: The use of solar panels saves you the extra cost of having to pay for electricity bills which is increasing at an alarming rate in recent times. Cost savings can also be calculated by eliminating the need to trench in grid power, disturbing surrounding landscapes and hardscapes, repairing areas and more. With solar panels, you can be assured of steady electricity supply as long as they are exposed to sunlight.
Easy Installation and Maintenance: Solar panels are easy to install, only need is a proficient solar panel installator, few bolts to hold them tights and some basic wiring. They are also not complicated to maintain if the maintenance instructions are followed.
Independent of Electricity: By making use of solar panels, you will automatically reduce your dependence on electricity or utility companies. You do not need to bother about going far to pay for your electricity bills or calling for electricity delivered to your home as you will be able to generate your own solar electricity through the use of solar panels. You will be able to watch all of your favorite Tv programs without being perturbed about the electricity going off because your electricity bill is exhausted.
MONOCRYSTALLINE SOLAR PANELS: These solar panels are among the oldest, most dependable and most efficient of solar technologies. They are made from a single continuous crystalline structure and can be identified from the solar cells which all appear as a single flat color. In appearance, it has a smooth texture and thickness. Monocrystalline panels are typically They are usually very rigid and must be mounted in a rigid frame to protect them. Monocrystalline solar modules suffer a reduction in output once the temperature from the sunlight reaches around fifty degrees Celsius/a hundred and fifteen degrees Fahrenheit. Monocrystalline solar panels are space efficient. They yield the highest power outputs and also require the least amount of space compared to any other types, they also tend to be more efficient in warm weather. Although they are more expensive than their counterparts, their longevity, performance, and efficiency mean that they’re a good buy over a longer period of time. They are the best modules to rely on when you want to be sure you’re producing the highest wattage per square foot. Monocrystalline panels have long life span. Most solar panel manufacturers put a 25-year warranty on their monocrystalline solar panels.
Because both types of crystalline solar panels are made from crystalline silicon, a very inert and stable material, it is very likely that these solar panels will last much longer than their 25-year warranty life. In addition to being sturdy and dependable, monocrystalline silicon solar panels are space-efficient. They require the least amount of space compared to any other type and they yield the highest outputs.
POLYCRYSTALLINE SOLAR PANELS: Polycrystalline also known as Multicrystalline solar panels are raw silicons melted and poured into a square mold, which is cooled and cut into perfectly square wafers. These types of solar panels are slightly less expensive than monocrystalline cells and need to be mounted in a rigid frame. They have a speckled reflective appearance and the thickness of the slice is conspicuous. Polycrystalline solar panels are made from a block of silicon that has multiple crystals. polycrystalline solar is made by pouring molten silicon into a cast.
However, because of this construction method, the crystal structure will form imperfectly, creating boundaries where the crystal formation breaks. This gives the polycrystalline silicon its distinctive, grainy appearance, as the gemstone type pattern highlights the boundaries in the crystal. Polycrystalline solar panels are simpler to produce, less expensive and are as reliable as Monocrystalline solar panels. Polycrystalline modules are fitted in the same way as other panels and do not incur extra charges as a result of being of a different crystal composition.
THIN FILM SOLAR PANELS: Thin film solar panels also referred to as Amorphous solar panels are solar cells made from a thin layer of photovoltaic material on a base plate of glass, metal or other substance. Thin-film solar cells are usually made out of amorphous-silicon alloys that are deposited in thin layers onto a glass or metal backing material called a substrate. Thin-film solar panels can be constructed from a variety of materials with the amorphous silicon (a-Si) being the most prevalent type. They are the cheapest type of solar panels because they still emerging. Thin Film solar panels are homogenous in appearance, flexible which makes them look more appealing and high temperatures and shading have less impact on solar panel performance. They can also be relatively flexible, mass produced and engineered to directly cover building materials such as shingles, from building-integrated PV systems to solar-powered calculators and garden lamps.
Conduct an adequate research on the size of your roof, shade of your roof, how much electricity you consume in a day, what day and what hour(s) you consume electricity the most, what your budget is and the Government schemes available in your area.
As a buyer, you should adequately find out how solar panels will affect your current electricity rates and what solar feed-in tariff they can offer – juxtapose your electricity and solar bills.
It is advisable to shop around for a good solar panel retailer shop and get multiple quotes which can be used for comparison from reputable solar retailers. Also, make sure that the chosen solar panel meets the required standards.
Contact a proficient, reliable and accredited solar panel installer. Increasingly, most local councils have expert solar panel installers as staff to assist with making the best decisions in the installation of your solar.
Find out if there are legal requirements required in your country before installing the solar panel. Also, find out what local council approval is needed.
Make sure that your roof faces the right direction, has access to sunlight, and is not obstructed by trees, powerlines or any other structures shading your roof. Only north-facing panels will produce their full capacity.
Ensure that the roof is large enough (usually a 15 square meter minimum) and that it can support the weight of the solar panels.
Ensure that your meter has been changed or reconfigured and the correct tariff has been applied to your electricity bill by your electricity retailer.
It is advisable to check with your insurer if your solar panel is covered by your current insurance policy.
Ensure that all necessary documents regarding your solar panel are in your possession.
Your solar panel installer should provide you with a maintenance schedule. The simplest ways to maintain your solar panel is by keeping the panels free of dust and debris and having the wiring checked by an electrical contractor periodically.
