Which Solar Panel to Choose?
It’s very important when selecting the best size of solar panels to use for your solar power system installation to bear in mind a few crucial factors aside from the price tag. After all, your purchase decision is one you’ll be living with for a very long time and it should provide you with a good return on your investment.
Don’t base a buying decision on solar panel cost alone – the following are a few tips for choosing the best modules for your installation situation.
How much do solar panels cost?
This depends on a number of factors – but generally speaking, in relation to modules suitable for use on a home and as part of a grid connect system installation; they cost a few hundred dollars each with subsidies taken into consideration.
The cost of a solar panel is determined in part by its capacity (in Watts), the physical size, the brand, quality of materials, the durability / longevity (or warranty period) and any certifications the solar panel might have.
The price you’ll pay will also depend on the number of panels as part of a package if you’re buying a full system. The more modules in the system, the less cost per unit (generally speaking).
The modules may not provide the best performance to help ensure economic payback of the power produced, or a solid warranty from a well-established company.
To give a broader overview, Suncov has put together some helpful information about the most common and special types of solar panels
|Solar Cell Type||Efficiency-Rate||Advantages||Disadvantages|
|Monocrystalline Solar Panels (Mono-SI)||~20%||High efficiency rate; optimised for commercial use; high life-time value||Expensive|
|Polycrystalline Solar Panels (p-Si)||~15%||Lower price||Sensitive to high temperatures; lower lifespan & slightly less space efficiency|
|Thin-Film: Amorphous Silicon Solar Panels (A-SI)||~7-10%||Relatively low costs; easy to produce & flexible||shorter warranties & lifespan|
|Concentrated PV Cell (CVP)||~41%||Very high performance & efficiency rate||Solar tracker & cooling system needed (to reach high efficiency rate)|
