Buying solar panels for your house can be an interesting knowledge but do not get too taken away by elegant ads. Focus on your needs and make sure your investment can power your house for a long period. The following are some tips in choosing the best residential solar power panels for your house.
The 3 levels of solar panels quality
There are lot of solar panel manufacturers and retailers guarantee top high quality products and merchandise. But how high quality their panels really are? Here are the 3 levels of screen high quality you ought to know.
Level 1 – includes the top 2 per cent of solar PV manufacturers in the world. They top to bottom incorporate residential solar panels. Significance they have control over each stage of their production process. These companies invest intensely on research and development and use advanced automatic procedures. Most of all, they have been in the trade for over 5 years.
Companies in this level use only the finest quality of rubber to generate the highest quality solar panels. In the solar panel technology sector, the higher the rubber quality, the longer the tissues will last and the more a system can perform. Tier 1 manufacturers generate some of the best solar modules.
Level 2 – these are organizations or manufacturers that do not spend on solar panel research and growth. They use limited automatic process and depend intensely on guide work from human manufacturing collections. These organizations usually are in the business from 2 to 5 years. Level 2 manufacturers offer excellent sections at excellent prices.
Level 3 – these are what we call assemblers only. They do not spend money on research and development or produce rubber tissues. They use guide labor in soldering residential solar sections instead of advanced robotics. Thus, no reliability in quality can be expected in this level as the workmanship differs from one employee to another. These businesses have usually been arranging residential solar panels for 1 to 2 years.
The cost of residential solar sections is identified by many aspects such as the dimension (in Watts), the product, the durability/longevity of the tissues (warranty period), the high quality of components used and any certification a board might have.
In the energy industry, you really get what you pay for but it is not also sensible to platform your choice on the cost alone. You need to know that the sections have the right certification for you to acquire of govt discounts as well as offer the best possible performance so you can offer unwanted energy to the primary lines (known as feed-in-tariff; the govt will pay you in every kW you nourish returning to the grid).
Types of solar cells used
There are 3 types of solar cells used in solar panels today. These are the:
Monocrystalline silicon - known to offer high efficiency and good heat tolerance
Polycrystalline or multi-crystalline cells - are the top choice of solar panels in the domestic sector. Recent improvements in polycrystalline panel technology have resulted in the development of panels at par or are better than mono crystalline brands.
Amorphous - only used a thin-film of silicon and known to be the efficient of solar panels
