Are you considering using solar energy to help you live a greener life and reduce your carbon footprint? There are some things to remember when selecting panels for your solar power device.
A solar panel’s price is calculated in part by its size (in Watts), physical size, brand, reliability / longevity (or warranty period), and any certifications it might have. It’s not a good idea to buy a solar panel based solely on price, as it may not fit in the space you choose to put it in, may lack the requisite certifications to apply for government rebates, or may lack the warranties needed for economic payback of the energy generated.

Longevity / Warranty / Durability
A solar panel’s resilience or longevity is essential for a variety of reasons. To begin with, if a solar panel has a 10-year guarantee and is used in a grid-connected device, the solar panel can provide enough electricity to compensate for itself within 10 years.
Furthermore, if the panel is to be included in a sensitive facility, you can avoid installing solar panels that aren’t as durable as the others. Solar panels with a good reputation can come with a 25-year guarantee.
Size and Wattage of Solar Panels
Since solar panels are generally priced (and compared) in dollars per Watt, the scale of the solar panel in Watts has a significant impact on the price.
Watts refer to each panel’s output; for example, a 100 Watt panel would produce 100 Watts of electricity per hour in optimal circumstances, whereas a 200 Watt panel would generate 200 Watts per hour. As a result, plan to spend twice as much for the 200 Watt panel as you can for the 100 Watt panel.
The actual scale of a panel is often affected by its capacity, so a 200 Watt panel would be bigger than a 100 Watt panel.
Efficiency of Solar Panels
There is a lot of discussion around solar panel performance, or how efficient the panel is at turning sunlight to electricity; nevertheless, it’s important to note that a 100 watt solar panel can yield 100 watts regardless of its efficiency level.
- Form of Solar Cell
- Solar cells are divided into three categories.
- Silicon that is mono-crystalline
- The most powerful and therefore yields the tiniest solar cells and, as a result, the tiniest solar panels.
- Silicon that is poly-crystalline (or multi-crystalline).
Produces the second most effective cell type, but comparable wattage panels are wider than monocrystalline equivalents.
The least volume of silicon is used in amorphous (or thin-film) silicon, which often contains the least effective solar cells. Thin film systems take up more space than the other two, but they have the benefit of being lightweight, allowing them to be used on angled or uneven surfaces that solid panels cannot.
Suitability of Solar Panels
In bright, cold environments, mono-crystalline and multi-crystalline silicon perform well, while amorphous (thin-film) silicon performs better at higher temperatures.
