How to Choose Solar Panels?

In 1839, 18 years old Alexandre-Edmond Becquerel discovered the photovoltaic effect (PV), which is the basic physical process through which sunlight is converted into energy. PV technology converts characteristics of impure silicon crystals and requires a high-tech manufacturing process. In spite of the high tech manufacturing process, you will find solar panel technology easy to use and cost effective in the epoch of rising costs of traditional fossil fuels. Major developments have aided with the progress of this technology, so you will find that it is now widely available for your use today.  

Keep in mind, that solar panel energy is durable and compatible with various sources of energy. Conversely, similar technology such as light-emitting diodes (LEDs), reverse the processes in which they run. LEDs and PV technology may synergize to supply you with adequate amounts of energy. They are efficient because they use sunlight, a renewable resource, and utilize the solar energy to operate power throughout your house for items such as fans. You should be aware that the solar panels that you opt to purchase will only be as efficient as the voltage output of the solar system. Therefore, you should make sure that you have batteries to back up your equipment if you want to ensure voltage stabilization. There are also several other factors such as watt size, physical size, brand, longevity, and certifications that should be taken into consideration when you choose your solar panels:

Cost and Wattage

You will further need a realistic assessment of your energy goals when you use a PV system. By knowing what you expect to use, you will be able to correctly assess how many solar panels you will need to match your current usage, and how you may be able to reduce your power consumption. This will also help you determine potential costs. Typically, though, solar panels are priced dollars per watt. It is best to determine how much wattage your appliances will need when choosing your solar panels. Therefore other variables such as non-standard appliances, like video games or plasma televisions, may significantly how many watts that you may use annually. According to The Open PV Project, which was conducted by the National Renewable Energy Laboratory of the U.S. Department of Energy, solar panels cost an average of $7.16 per watt since 2010.  For every kilo-watt that you use, you will need 100 square feet of solar panels. Furthermore, you should do research that particularly applies to your hometown. In the United States, the amount of power that you may obtain from solar panel energy will vary because of the differences in sunlight from state to state. Also keep in mind that the more physically larger your solar panels are, the more wattage your panels will use; conversely, the more wattage that you use, the more you should expect to pay for the cost of the panels.

Solar Cell Type

There are three types of solar panels to choose from. Remember that you may want to purchase a specific type of panel based on your specific preferences for size. You may choose from three types of solar cells: (1) Mono-crystalline silicon, which is the most efficient and produces the smallest panels and solar cells; (2) Poly-crystalline silicon, which produces the next most efficient type of cells. But equivalent wattage panels are larger than mono-crystalline silicon; (3) Poly-crystalline (or multi-crystalline) silicon, which uses the least amount of silicon and is the least efficient. It takes up more area that the other two, but offers flexible panels that can be used on curved or irregular surfaces not suited to solid panels.  

Solar Power Efficiency

Efficiency ratings for the different types of solar panels are inconsistent.  A 100 Watt solar panel should produce 100 watts, therefore keep in mind that the solar panels should produce the watts that it is designed to produce when choosing your solar panels. You may also determine efficiency by paying attention to what terms and conditions apply to your solar power brand’s warranty. A good rule of thumb to remember is that solar panels with a warranty of 25 years are more reputable than panels with a warranty of 10 years. In so far as costs are concerned, the longer your solar power energy will last, the more you will save on long term costs.


Solar Panel Suitability

If you live in bright and cool conditions or a roof without shade, then you might want to invest in either mono-crystalline or multi-crystalline solar panels. If you face higher temperatures, or if your roof has partial shading, then it will best for you to select amorphous silicon panels. Generally speaking, the more light that your panels are exposed to the more power that they will produce, so it is advisable to place your panels in areas that aren’t shaded. Since the amount of shade your panels will be susceptible to is variable, the “shade torrent” features you may see advertised may be misleading. Again, this information differs from location to location and depends on the state that you live in.

Overall, solar panels and PV technology improves the telecommunications infrastructure and supports radio and television services. It uses a network to supply lighting, household power, and energy metering. As you continue to buy solar panels, it is advisable to do your research beforehand. Recent developments show that hair might replace silicon technology in the face of global warming and degrading natural resources. Who knows? Maybe you’ll be the first person to utilize such technology! Currently, several manufacturers such as GE, Evergreen, Sharp, and Schott provide PV merchandise for you use. After you choose the type of solar panel, you may choose from flexible installation options, such as the grid-tie application which utilizes a combination of PV modules, inverters, and a network to supply lighting. When architects use this system, they combine function and aesthetics by integrating glass panels into building structure and design. Alternatively, remote applications will provide public lighting, assist high-powered pumping systems, and enhance telecommunications in off-grid homes.
