How to Choose Solar Panels?

Solar panel technology is one of the most influential discovery and invention in the world. It has the potential to revolutionize energy production systems globally. There are many solar companies that are manufacturing various solar products. Many companies are manufacturing solar panels, the basic component of a solar system with different qualities, specifications and types. It often becomes very hard to choose the company that can provide the right solar panels for your PV system. When it comes to choosing the perfect solar panels, there are certain parameters that you can use to see if you are buying the right solar panels or not. Keep in the mind the things below to make sure that your solar panels will not let your investment go to waste.

Solar Panel Quality

This is undoubtedly one of the most important factors that you need to consider while buying your solar plates because the quality of the solar plates will decide the energy production and longevity of your system. Some solar producers invest a lot in R&D and manufacture PV panels using the highest quality of semi-conductors. These are the panels that you need for your system. Comparatively, some companies don’t invest in R&D and utilize solar cells made from other manufacturers. They use human labor instead of modern industrial techniques to assemble their panels and thus produce affordable but low quality panels. They can be classified as Tier 4 panels.


Energy Efficiency      

Efficiency of a solar panel is the measure of the amount of electricity produced by a solar panel after absorption of sunlight. A more efficient solar panel is also more expensive, but it does not mean that it’s always the right choice for your system. A good energy audit will tell you about your electricity needs and the best efficiency of solar panel for it. The idea is to neither underestimate nor overestimate the efficiency factor of solar panels. In simple words, even if you can own a Rolex, buying a simple wrist watch to be able to tell time is much more reasonable.

Durability

Durability means how good a product is and how long you can keep using them. To check the durability of a product, the best way is to check the warranty of the modules. The panels that have a long warranty are more durable and reliable as well. This is because long warranty means that the manufacturer has confidence in their product and believe that it will go a long way. Comparatively, solar manufacturers who are not giving adequate warranty are not confident in their Product, showing that it is not durable. The long warranty also means reliability as you can get new panels in case any thing bad happens to your solar plates.

Size and Capacity

The size of the solar panel refers to its dimensions. It does not matter a lot in small residential solar projects as the variation in this size is quite nominal. The size that makes an impact on your solar panel system is the capacity of the solar panels. You will need to find the right Solar Panels that fulfill your electricity needs and can also be placed on your roof or any other available space. The easiest way to understand this is to suppose your electricity bill is around 500 units per month, so you will need a 5kW solar system. If you choose 345-watt solar panels for this system, a total of 13 solar panels will be required. However, if you go for 450-watt solar panels, you will have to use only 11 solar panels. So, you may need to choose the capacity according to your bill size and roof space.

Types of Solar Cells Used

There are different types of solar panels with different efficacies. Monocrystalline silicon offers high efficiency as it is manufactured with high-grade silicon wafers. Polycrystalline (or multi-crystalline) silicon cell use the fragmented silicon and are not that efficient. Monocrystalline solar panels are most widely used now as they can provide more electricity with a smaller sized solar panel and are better at performance.

If You Are Still Not Sure

Choosing the right solar panel can be an arduous task that can take its toll on you if you do not have the basic knowledge of everything solar. To get rid of the hassle, consult a Solar Expert so that you can opt for the right solar panel and Solar System for you.

Longi Solar Panel Review

Image
LONGi Solar was set up in 2000 and is completely claimed by the LONGi Group situated in Xi'an China with assembling offices in Malaysia, Vietnam, India, and all through China. LONGi has developed quickly in the course of the recent 5 years to be delegated the world's biggest solar organization dependent on sales income and market capital in 2020 with an unbelievable yearly creation limit of over 110GW, including 25+ GW for panels, 30 GW for cells and more than 55 GW for wafers. LONGi Solar produces only monocrystalline panels, and the organization was to a great extent responsible for driving the solar industry back towards the more proficient monocrystalline cells after polycrystalline cells had ruled the market since 2012 because of lower production costs. To accomplish this progress, LONGi Solar began constructing new facilities and altogether increase the creation of monocrystalline wafers to supply the whole solar industry with cheaper mono-Si wafers and cells.  New Solar...

Parts Required For a Solar System

Image
An ever-increasing number of people are choosing to install solar panel systems. Their stimulus is to decrease long-shot energy costs while limiting their carbon impression. This quick progression has originated mostly from enhancements in the productivity and lower cost of the most recent solar energy systems. All in all, what is needed to make an effective solar system arrangement for home use? What parts are required? What Is A Solar Panel System?  Rooftop mounted solar panels absorb and convert the energized photons of normal daylight into usable electricity, thus also called PV, or photovoltaic, solar energy system. Home establishment of an excellent solar system can reduce or completely end reliance on the local area power network that provides electricity to power your home. The consequence of a private solar establishment is a splendid, environment-friendly power source that requires negligible upkeep with savings that will pay for the system within a few years.
