It is imperative to know the type of solar panel that you are looking for because it will determine the energy that you will get from the solar panel. The direction and angle of the roof should be facing between 10 and 60 degrees. This will let the solar panels work at their peak in converting solar energy to electricity. It is imperative that you avoid shade as much as possible. Moreover, existing temperature should allow the airflow to cool the panel down. Depending on the time of the year, you will get a certain amount of solar energy. You should look for solutions that are effective. Before you choose the best solar panels, it is vital to understand basic math. The efficiency of a solar panel refers to the ratio of incoming sunlight to the power that is generated by the solar panel. Therefore, in situations where you have 100 watts of sunlight and upon reaching the panel, you will get 10 watts. The solar panel is said to be 10% efficient.

There are two types of panels – the thermal panels that use sunlight to heat water, and photovoltaic panels that convert solar energy into electricity. Most photovoltaic panels have the efficiency of about 10-23% depending on the model, while the thermal panels have an efficiency of up to 90% because there is no energy lost during the heating process. In most cases, the best solar panels are manufactured to work at enhanced efficiency. Lab-based assessment is considered as label rating and it is used to give an idea of what to expect in a solar panel. Some solar panel manufacturers provide an in-situ efficiency rating on a typical installation. This is called performance test condition rating and this is a rating that will guide you on what to expect in practice. The system performance test condition includes efficiency of the solar panel, investors and other devices on the electrical field. Inverter efficiencies are known to range between 85-95%.

Temperature Coefficient or Performance

Temperature Coefficient or Performance

Temperature Coefficient or Performance

LG solar company has worked to improve the temperature coefficient and performance of their solar panels. Temperature coefficient indicates how well the solar panel will perform in less ideal conditions. Solar panels operate well when they are kept in ideal conditions or in cool temperature especially 25 degree Celsius. The temperature coefficient gives you an idea of the solar panel performance and how it will change during hot summer days or during cold winter days. For every degree Celsius above the standard temperature, the solar panel electricity production will decrease. For example, LG LG310N1C-G4 panel is tagged with the temperature coefficient of -0.38%. This means that when the temperature rises from 25 degree Celsius to 26 degree Celsius, production of electricity will reduce by 0.38%. If the temperature increases by up to 10 degree Celsius, then electricity production will decrease by 3.8%.

The temperature coefficient is an essential metric to consider because the solar panels will see more cold or hotter days over the course of its use. Ideally, the temperature coefficient of the solar panel should be as close to zero as possible. However, this is not possible to produce because the material affects the quality of the panel. In this context, a solar panel with a temperature coefficient of -0.4% is better than that with a temperature coefficient of -0.5%.

Warranty

Warranty

Warranty

Whether you are buying a television, car or solar panels, the manufacturer is required to produce a warranty card that will help you backup your product. Solar panel material warranty is sometimes called equipment warrant or product warranty. It is a guarantee that the manufacturer will replace the solar panel in case the equipment fails because of environmental issues or manufacturing defects. Most solar panel producers in the market offer a 10-year warranty but it is important that you buy solar panels with a warranty of 12, 15 and 25-year warranty.

Typical-Layout-Off-Grid-Residential-PV-System

Off-grid systems refer to systems without connection to the utility grid. Thus, people using an off-grid system will have to ensure that every part of the house gets electricity.  

For an off-grid solar system, you need four basic components and they include a solar panel, charge controller, inverter and battery. Before choosing the components, you have to calculate your power load and how long the off-grid system will run. The next thing to do is to select the batteries. The output from the solar panel in an off-grid system is direct electrical power.

The next step is to select the solar panel. Solar panels convert sunlight into electrical current through the photovoltaic effect. These solar panels are categorized into monocrystalline and polycrystalline. Monocrystalline solar panels are more expensive and more efficient compared to polycrystalline solar panels. The size of the solar panel should be considered carefully to ensure that the battery charges to full capacity daily. Once the solar panel has been selected, choose a charge controller. This device will be  placed between the solar panel and battery to ensure regulation of voltage and also that of current coming out of the solar panels.

After selecting the charge controller, choosing an inverter is next. The three popular types of inverters include modified sine wave, pure sine wave and square wave inverters. They may be cheap but are not recommended for most appliances. The same case applies for the monitor sine wave inverters which are slightly more expensive than square wave inverters. The solar panel now has to be installed. It is advisable to get an expert to do the installation. Companies whose area of specialization is installing off-grid solar panels are more capable of installing it properly. It is also good to choose a solar company that has the most references and positive reviews from clients whom they have served before.

Off Grid system

Off Grid system

As off-grid solar systems are not associated with the electrical grid in any way, the power in a building using an off-grid solar system will not go off during a power failure. However, it is important to take note of the storage space in the batteries in an off-grid solar system as well as the extra expenses you have to go through to buy them.

There are many reasons why people prefer off-grid solar systems.

Environmental concerns are essential in this. Most people have directly felt the impact of global warming in their lives and realized that they should be using less energy. Some people also prefer to generate their own electricity. Social values, political issues and the high cost of using electricity from the power grid all play a role in converting people to off-grid solar system users. Generally, the further away a house or building is from the power grid,  more expensive electricity will be. So, it makes more sense to be generating your own electricity from an off-grid solar system in this case.Think about the huge savings and environmental benefits you will be enjoying from using an off-grid solar system.

How Solar Works

The extensive use of non-renewable sources such as oil, gas and coal is escalating at a shocking rate. That is why more people are now exploring renewable sources of energy such as solar energy. It is harvested from the sun using a wide variety of advanced technologies such as solar heating and cooling, solar thermal energy, photovoltaics, solar architecture and artificial photosynthesis.

Solar energy readily available in large quantities makes it a more practical and viable alternative source of electricity. Photovoltaics is used to produce electricity by converting sunlight into electric current. Solar thermal power plants also make use of solar energy to generate electricity. The heat produced is used to drive steam turbines that generate electricity. These two technologies are examples of active solar technology.

Solar heating and cooling technology uses the energy from the sun to provide space heating, cooling, hot water and pool heating for commercial, residential and industrial places. This technology is affordable to many, creates jobs for people and rids the need to use electricity generated by fossil fuels. The solar architecture incorporates the use of solar panels and passive solar buildings designs which involve constructing windows, floors, and walls in such a way that they absorb and store solar energy in the form of heat. This energy is expelled during the hot season and retained during the cold season. In artificial photosynthesis, energy from the sun is captured and stored in the chemical bonds of a solar fuel (a fuel generated from sunlight).

The most important fact of solar energy is that it is completely free. Solar energy is always renewable because the sun is not likely to be depleted. It is also environmentally-friendly as it does not pollute the air, environment or deplete any natural resources. Solar energy can also be used anywhere in the world as long as they have the supporting technology and installation. It is easy to install solar panels and they are fast  becoming common features in many homesteads and commercial buildings today.

Solar energy pricing

Solar energy pricing

Determining solar energy cost depends on the amount of electricity you use in your house, the roof area available to install solar panels and how many sunlight hours your location gets in a day. Solar panel prices vary depending on the building, type and brand of panels used and the installation company. The prices of solar panels are priced by manufacturers based on their efficiency.

Though solar energy has a host of advantages, it is not without any drawbacks. Appliances relying on solar energy can only work during the day because that is when there is daylight. At night, you may have to resort to other alternative sources of energy if you do not have storage devices for excess solar energy. The solar technologies are also very costly and require large pieces of land for setting up.

How Much Does It Cost To Install Photovoltaic Cells?
solar energy household self consumption

solar energy household self consumption

Self-consumption is the portion of generating solar energy which is directly used by household electrical appliances such as televisions, washing machines, electrical cookers, among others in a building where a photovoltaic system is located. This means that the electricity you generate is for your own needs instead of being fed into the grid. Self-consumption is now commonly used in solar power plant operators who use the electricity their plants generate.

Self-consumption is determined by the types of electrical appliances in the building and the number of people living there as well as their power consumption patterns. The more people there are, the higher the rate of self-consumption. Also, some appliances use more electricity than others. The amount of solar energy consumed is directly proportional to the electricity consumed.

Self-consumption reduces the burden on power grids. This is because the solar energy generated on-site can be used directly by the people there instead of first directing to a public power grid and then redirected to the location of production afterward. This also offers huge savings as the people using or living in that building do not have to purchase electricity for self- consumption. Self-consumption helps you save money which could have otherwise be used to pay electricity bills. Self-consumption also reduces the burden on public voltage grids.

How-Photovoltaic-Systems_Work

How-Photovoltaic-Systems Work

Self-consumption cannot be the only source of energy for buildings using photovoltaic systems as solar power is not generated in the same amount every day and more energy may be required on certain days. For instance, on a day when there is no daylight, the solar energy generated is less, therefore. self-consumption decreases. Self-consumption also poses a challenge when the demand for electricity is higher during a season like a winter.  

Self-consumption can be optimized effectively to benefit consumers in several ways. The best way to increase one’s self-consumption is by storing excess solar energy in lead acid or lithium ion batteries. The stored energy can then be used later on when the sun has set.

It is also very helpful if you adjust your electricity consumption behavior. For example, use only one electrical appliance at a time. When you are using the washing machine, you should not be operating the dishwasher alongside it. It also helps to run those appliances that need a lot of power during the day and the ones that use less electricity at the night. Appliances which are activated automatically, such as remote controls can also contribute to optimizing self-consumption.

With careful strategies of maximizing self-consumption of solar power, this affordable and clean source of alternative energy can  become increasingly dependable.

How Photovoltaic Cell Work?

 

Photovoltaic cells are made of two different semiconductor layers. Negative and positive charges are found on each distinctive side. For photovoltaic cells to function, they must be exposed to sunlight. This is because sunlight has smaller particles known as protons which aid the cells to work. When exposed to sunlight, sunlight is absorbed by the cells. This is the first step in transforming light energy into electric energy in photovoltaic cells.

The negative layer of photovoltaic cells needs to absorb enough sunlight to free itself from the negative semiconducting material. This makes these electrons move freely into the positive layer of the semiconductor. This is to create a voltage difference which kick-starts the change of sunlight to electrical energy.

pros & cons of Photovoltaic Cells

Just like any other product, photovoltaic cells have both limitations and advantages which help them run smoothly. They aid in the production of Direct Client energy which can be used directly in appliances that allow direct client voltage or can be converted to Alternative Current with the use of an inverter. Advantages of photovoltaics:

  1.   They reduce combustion rate by providing clean energy.
  1.   They are readily available in many places. You may need to consult your local shops to find out.
  1.   This type of electricity can be easily generated from sunlight or artificial light.
  1.   Photovoltaics is an inexpensive source of electricity.
  1.   Minimal wear and tear since there are no moving parts.

With all these factors in play, using a photovoltaic cell becomes an efficient way to power up electricity in your home or workplace. However, they may be some downfalls too. Some of this include:-

  1.   You need to buy an inverter if you want to change your electricity current into an Alternating current.
  1.   They are costly.
  1.   They are made of fragile materials and must be kept in a safe place.
  1.   Innovations happen on an almost daily basis. Hence, you may need to buy new electrical appliances very often which may not be suitable for photovoltaic cells…
  1.   Photovoltaic cells are rather bulky and require some space for them to function well.

Summary:

Photovoltaics are the way to go. Not only do they are an eco-friendly source of energy, they also help reduce the cost of electricity.

A solar power energy plant may not be as costly as it is presumed. Numerous websites talk about the how-to of fixing photovoltaic solar panels for household and commercial uses with the aim of using solar power to generate electrical energy. Some sites also offer consumers with an opportunity to calculate the amount of money it would cost them to build such a solar power panel in their homes or offices.

It is estimated that an average house in the US spends roughly about 1kW per hour. It comes up to about 750 hours each month. If the price of a kWh is $0.10, the monthly bill for an average household would be $73. With time, many appliances are added to the house and this affects the amount of electricity consumed and this leads to a bigger bill. Electronic devices consume a significant portion of electricity in the house and the household electrical bill may vary depending on the types of electrical devices in the house.

However, the cost of electricity varies in the United States of America. This is because different states have different policies that govern the amount of electricity used For example, in Virginia, electricity may cost about $0.07/kWh which would be calculated as $0.24/kWh in Hawaii. This shows that the cost of electricity per kWh varies with the state and the amount of electricity used.

Solar panels are increasingly popular devices which help us harness solar energy. They absorb sunlight and convert it to electrical current that is used in various households and commercial buildings. The question is, are solar panels worth it?

Solar panel efficiency is the measurement of the panel’s electricity output compared to its surface area. The cost of solar panels increases with their efficiency. The area of the roof where the solar panels will be installed is also something to consider before installation. The bigger the space, the smarter it would be to buy less expensive solar panels.

Even though the efficiency of low-cost solar panels may be lower, they become more cost effective with time. If the roof area is small, it would be better to pay a little more to buy a few very efficient solar panels. The efficiency of a solar panel can be increased by considering the tilt of the roof where they will be installed, the shade and temperature. The tilt of the roof can affect the number of hours of sunlight received. A solar panel placed under the shade is not efficient since sunlight is prevented from reaching it.

The prices of solar panels vary depending on their size and type, and also the structure of the building where the installation will be done. When you are deciding to buy solar panels, you may want to consider a system that includes battery storage. This is so that the energy stored during the daytime can be used later at the night or on a day when there is not enough sunlight.

Solar panels are worth a lot because they are a way of making money and reducing e the cost of electricity bills as you are able to produce your own electricity. Solar panels are connected to the national grid and one is paid for supplying this electricity. In addition, any excess  electricity can be sold to an electricity company. This means income generation for the owner of solar panels. Solar panels are also quite reliable as the sun is a consistent source of free energy

As much as solar panels are very efficient in many ways, they do have their limitations as well. Their efficiency depends on the number of daylight hours and the weather. Dull days with dark clouds prevent sunlight from reaching the solar panels. Therefore, insufficient electrical energy is generated. Solar panels can also be quite heavy and the roof where they are going to be installed has to be strong enough to take their weight.

Solar panels can be of great use to many people and it is an option that should be considered.
