5 tips to consider before buying a solar panel

A solar panel can help you save on household energy costs as you no longer have to pay for electricity. Most people find it tasking when it comes to choosing the right solar panel. Here are a few tips to consider for before buying a solar panel.

  • Choosing the right material

It is important to choose the best material before buying a solar panel .There are two different materials to select from .Carefully weigh the pro and cons of each material to make the right decision.

The first material is monocrystalline which contains uniform crystals made from large, pure silicone crystal bars. The large, pure crystals give the panels the increased efficiency since there is no wasted space between the crystals. The uniform nature of the panels makes all the crystal face the same way. This means it cannot absorb light in multiple angles, however if placed in the right direction, in strong sunlight it can absorb massive amounts of solar energy. They are more suited to smaller spaces. They are more expensive and fragile because they are more efficient.

The second material is polycrystalline .It has a crystalline construction which is molded and purified to form a pure crystal panel. They are less efficient compared to monocrystalline and are less expensive .In its circumstances due to their misaligned structure it absorbs more light from multiple angles. They are most beneficial in low light conditions and tend to have a more intense shade of blue where the random crystal arrangement can be seen. These panels have a longer life span and works best in duller weather.

  • Space and location

When it comes to buying a solar panel one must put into consideration how suitable is the space and location they have for the solar panels. In low light areas especially if the space is available polycrystalline panels are the better option. This is because they can draw the solar energy from any angle thus more effective. In smaller spaces that receive strong sunlight, monocrystalline panels are more suitable .One should always consider the optimum efficiency and the energy return .The installation area should be clear, this means no obstruction whether from trees or large buildings.

  • Condition of the solar panels

There is always the option of buying a used solar panel. If one is considering to buy a used solar panel it is imperative to look at the overall condition of the panel before buying it. Check if there are any visible dents, cracks or scratches. Ensure the panels have not burnt or melted and they are free of moisture damage. Check every module is in good condition before buying a solar panel. It is important to note that if a single module is broken then the whole module string breaks hence reducing the efficiency of the panel.

  • Cost and potential saving

Be sure to evaluate the potential savings before buying a solar panel. This will allow you to know how long it will take until the panels pay for themselves .It allows you to calculate how much you will be saving in the long run .The initial outlay for buying and installation is relatively expensive ,panels correctly mounted and located tend to make a great future investment. In the long run, it helps you cut home energy expenses and gives you the possibility to sell the surplus energy to energy companies. It is good to calculate you will be able to save by buying a solar panel

  • Choosing the correct mounting option

This is a really important matter to consider before buying a solar panel .The mount safely secures the panels in place. Roof/ground mounts are a great choice for large solar panels or multiple solar panels installation. They provide a tilting mechanism thus maximizing the efficiency and the lifespan of the panels. Flush mounts have metal brackets that join to each corner of the giving it appropriate elevation. They are cost-effective .Pole mounts are best suited for limited wall or roof space. They secure the solar panel to a tall pole through a bolt system and they are not suitable to use in windy regions.
