Much manufacture & suppliers all over the world produce 12 volt solar panel's product with different type, quality, price and watt. China as a fast growing industrial, produce many kinds this device. However, we not yet know the quality of china's solar panels because china is still the new player in this market. There are a number of factor worth considering when choosing 12 volt solar panel.
Price
The size (in Watts), the physical size, the brand, the durability / longevity (or warranty period) and any certifications the solar panel will determine the price of a solar panel. Government certification, the need of your home power, the area you wish to install is the important factor besides the price of solar panel itself. Choose wisely when you purchase your 12 volt solar panel.
Durability / Longevity / Warranty
You should consider the durability and longevity of a solar panel before making a purchase. The solar panel's payback period is affected by durability or longevity of solar panels itself. For example, you have to calculate your return on investment within 10 years if you bay a solar panel which only has a 10 year warranty. I recommend you to buy more expensive solar panel which guaranty you with longer warranty and good quality, especially if you want to use for a critical system.
Company is also important to consider relating to warranty. Don't buy 12 volt solar panel from un-credible supplier because will difficult because it will be difficult in terms of warranty. An important point to remember about warranty is that it will only be honoured for as long as the company operates. Choose the best company will give you good quality, price and warranty.
Size and Watts
The important factors you have to consider are whether your solar panel system overall has enough watts to power your appliances and it will physically fit in the area you wish to install them. The price of solar panel will directly be affected by the size of the solar panel in watts. The 200 watts of the solar panel will have more expensive and larger size physically than 100 watts of the solar panel.Â
Type of solar cells used
The type of solar cells used in solar panel also needs to be considered. Type of solar cells will affect the price and space required to installation. There three main types of solar cells that is Monocrystalline silicon, Polycrystalline (or multi-crystalline) silicon, Amorphous (or thin-film) silicon. Thin film panels are quite a bit cheaper than mono-crystalline and poly-crystalline, but they do require a great deal more roof space.
