It will be a bit difficult to decide which solar panel is the most suitable for you. If you don’t even know the basic knowledge of photovoltaics, it is recommended that you contact experts to choose the best solar panel for your specific situation.
However, by discussing some typical issues, you will be able to obtain some ideas that may help you choose the most suitable solar panel for your home use.
Due to its dependence on many factors, such as load requirements, the environment and region of peak sunshine hours, and the type of battery used as a backup power source. In addition, the efficiency of monocrystalline solar panels is better than that of polycrystalline solar panels.
As is well known, ‘cost and space’ are the main factors in selecting photovoltaic panels correctly, so we will briefly discuss this topic.
Space:
Due to the limited space on roofs, windows, and other surfaces for most of us, thin film solar panels are not suitable.
If size is important, which one is the best? 
Monocrystalline solar panels are more space efficient, while polycrystalline solar panels are slightly cheaper, but also have lower space efficiency.
For the same rated power (such as 150W), monocrystalline and polycrystalline solar panels will generate approximately the same electrical output power (almost negligible difference), but compared to monocrystalline solar panels, polycrystalline silicon will occupy more space.
Cost:
The price of photovoltaic panels is usually listed in the form of cost per watt ($/Watt). If you want to obtain the cheapest price per rated power, you must compare the prices of different monocrystalline and polycrystalline solar panels available in the market and on the internet.
Output as King
The warranty period for solar panels by photovoltaic manufacturers is approximately 25-30 years. But please remember that over time, the performance of solar panels will gradually decrease, and as it approaches its expiration, the overall performance will still maintain 80%.
Therefore, do not compromise on the output power of solar panels, and make the installation system of your designed solar panels reliable. Once again! Don’t buy cheap photovoltaic panels, otherwise, you will have to pay the price again!
