Solar Panel Buying Guide
Utility bills are constantly on the rise. In fact, these are only bound to go even higher as time goes by, which means it is practical to start thinking of ways to minimize your dependence on the traditional source of powering your home by harnessing energy from the sun. This way, you can save more money and do your part in reducing carbon footprint at the same time. By purchasing solar panels, you can significantly reduce the cost of your electric bills since these units generate energy from the sunlight they absorb. Considering the amount of sunshine you receive each day, it is best to start being more proactive and making use of nature’s gift to us.
But the thing is, there are so many things to consider when buying solar panels to make sure you get the right one you need. The mounting system is another component to think about since this impacts how easy or tough it will be to install the unit. There are also different types of panels you can find, along with the mounting options and the efficiency rating of each. Then, of course, you need to be aware of the location and space where you are planning to set up the solar panels.
To guide you further on how to select the perfect solar panel from the wide variety of available ones on the market.
- What is the best material for a solar panel?
Naturally, the material the panel is made from has a huge effect on the durability and performance of the unit. There are also benefits and limitations that each material comes with, which you have to look into before you make a decision. Polycrystalline is purified and molded, and the panels are made from pure crystal. But what you need to know about this material is the reduced efficiency, as compared to what monocrystalline panels offer. This issue is due to the crystals that are within the panels, specifically the loss of efficiency at the joints and due to the uneven alignment of these crystals. At the same time, the misalignment can also turn out to be a good thing since the absorption of light from multiple directions and angles make these crystals suitable for use in low-light situations. As for the appearance of the material, polycrystalline comes with a darker shade of blue with visible random crystal formations.
With monocrystalline panels, there are uniform crystals in them. These are pure silicone and large crystals, which means there is higher efficiency with reduced wastage of space in between the crystals. Moreover, there is one direction in which the crystals face, so this is excellent if they are situated in the ideal direction and in an area that receives massive sunlight. The outcome is the absorption of a higher level of energy, with the exception of conditions when sunlight is scarce.
- Where will you install the solar panels?
Think about the amount of space that is available for the solar panel you are looking to buy. If you live in a place where there is intense sunlight, yet the area is only small, you are better off with monocrystalline solar panels. On the other hand, if there is a bigger space and the location is more of low-light most of the time, you should consider getting polycrystalline ones to boost efficiency as light is pulled from various angles.
Also, when you buy a solar panel, think about the presence of obstructions in your location. Large buildings and overhanging trees can decrease the energy return and the efficiency rating of the panels. So, be sure the installation area is completely clear of such obstructions.
- What is the mounting option?
However, if you are using a larger solar panel or even multiple panels that need to be installed, ground or roof mounts should be ideal for this situation. There is a tilting type of mechanism in these mounts, which can help increase the life span and efficiency of the solar panels. But if space is an issue, pole mounts are perfect. These secure the panel to a high pole by utilizing a bolt system. Just steer clear of pole mounts if you are in a place where it is often windy.
In the long run, solar panels can result in higher savings, although the initial investment may be a bit overwhelming for some. You can eventually get rid of your energy costs at home while selling unused energy to companies for even greater profits in the future.
