So how do you find the best solar panels for your money? There are certain specifications you should use when evaluating your solar panel options, such as power output, efficiency, or even temperature coefficient. It’s not always clear from the get-go. “Best” will mean different things to different people. However, for the most part, people care about efficiency and long lifespan.
Perhaps you want something that gives you the best value for money.
We applied our own experience and expertise in solar panels to bring you handpicked recommendations of the best solar panels for your money.
What to Consider When Looking for the Best Solar Panels for the Money
But before that, we’ll give you a quick overview of the factors we considered before picking the best solar panels for you.
i) Cost Per Watt
Panels come in different sizes and shapes. Full-size panels provide around 250 to 400W of power, although you’ll find smaller panels for off-grid applications (such as RVing and boating)
The most important thing to consider is the cost per watt. Simply divide the panel’s price with the power output in watts. This will give you the true pricing number, which can be used to provide a comparison of other panels.
The efficiency rating of a solar panel refers to the amount of sunlight that it can convert into useful energy. To be considered deficient, the solar panels should be able to convert at least 14 to 20% of the sun’s energy.
As a general rule, monocrystalline cells are the most efficient technology that money can buy. You can also settle for polycrystalline and amorphous cells that are more affordable but less efficient.
iii) Temperature Coefficient
Most solar panels perform best when kept in climate-controlled situations. This isn’t always the case, especially when you’re going off-grid. Depending on how far off your climate conditions are, your system will lag behind its rated efficiency.
The impact of temperature on the panel output is measured with the temperature coefficient. It measures how much efficiency is lost for each degree above or below ideal test conditions. For the most part, the temperature coefficient isn’t the most important variable to focus on unless you live in an area that is very hot (or cold).
