Types of Solar Panels
While monocrystalline and polycrystalline panels are the most common, advancements continue to emerge. Monocrystalline panels are generally more efficient and aesthetically pleasing but can be more expensive.
Monocrystalline vs. Polycrystalline
Monocrystalline panels are made from a single silicon crystal, giving them a uniform black appearance and higher efficiency. Polycrystalline panels are made from fragments of silicon crystals, giving them a blue, speckled appearance and generally lower efficiency.
Panel Degradation
Solar panels are designed to be durable, but their performance will naturally degrade slightly over time. Manufacturers typically provide a performance warranty guaranteeing a certain percentage of their original output after 25 years.
Understanding Performance Warranties
Pay attention to the specifics of these warranties. A common guarantee is that panels will retain at least 80-85% of their original output after 25 years.
Inverters
The DC electricity produced by your solar panels needs to be converted into alternating current (AC) electricity, which is what your home’s electrical system uses and what the utility grid accepts. This conversion is done by the inverter.
String Inverters
These are the most traditional type of inverter. Multiple solar panels are wired together in “strings” and connected to a single inverter.
Pros and Cons of String Inverters
String inverters are generally less expensive upfront but can be susceptible to reduced performance if one panel in a string is shaded or underperforming.
Microinverters
Microinverters are installed on each individual solar panel. This means each panel has its own conversion of DC to AC electricity.
Benefits of Microinverters
Microinverters offer better performance in shaded conditions as the underperformance of one panel doesn’t affect others. They also allow for more granular monitoring of individual panel performance.
Power Optimizers
Power optimizers are a hybrid solution. They are installed on each panel to optimize DC output before it’s sent to a central string inverter.
How Optimizers Enhance Performance
Optimizers can improve overall system efficiency by mitigating the impact of shading and panel mismatch, offering some of the benefits of microinverters at a potentially lower cost.
