Sun is the source of never-ending energy, which we as humans have not been able to fully utilize so far. We are dependent on other sources for power when we have the sun to provide us as much energy as we want. However, times have changed and special gadgets are made by humans to absorb the sun’s energy and transform into power that can be used by mankind in several ways. Solar panels are one of the many devices that absorb the sun’s energy and convert it into electricity. Solar panels have been in use for the past many decades, but they were used predominantly for commercial purposes. However, in the last decade or so, solar panels have made their way into residential settings as well. Solar panels are available for generating electricity at home, so if you are interested in doing the same, then you better check out reviews of the best rated solar panels consumer reports consisting of six amazing products.

How To Choose The Best Solar Panels

When buying a solar panel, there is no need to pay attention to how the conversion of light energy to electrical energy takes place. However, you need to take a thorough look as to how the solar panel will perform because that is the key to determining as to how much you can save with it. Let’s dive into the factors that will help you decide the best solar panel.

Solar Panel Ratings

When you check a solar panel, there will be a nameplate at the back or bottom of the plate where you can find the power rating of the unit. Power rating refers to the amount of power a solar panel has produced when tested right after the manufacturing process. The majority of solar panels that are available on the market have a power rating around 200-350 watts.

A solar panel with a higher power rating will produce more power. But, there is a catch in power rating of the solar panel, i.e., the power rating was calculated under ideal conditions, which most solar panels won’t get when those are rolled out into the retail stores. Yet, power ratings of solar panels are used to compare panels.

Power Tolerance

Certain variations sneak into the solar panels, and the worse part of those variations is that those can’t be avoided. Power tolerance is the difference of the actual power output of the solar panel than the power rating given on the nameplate. You will generally find power tolerance expressed as (+/-), so if you are using a 250-watt panel, then you will get a +/- 5% power tolerance, so that means, if the actual power of the solar panel is written 250 watts, then it will produce anywhere between 237.5 to 262.5 watts.

A solar panel that has a narrow power tolerance is preferred compared to the one, which has a wider gap simply because it represents more certainty. Make sure to check the power tolerance on the solar panel while checking power rating.

Solar Cell Efficiency

The efficiency of a solar panel is calculated by its ability to convert solar radiation into electricity. The efficiency of the most effective solar panel that is available on the market is around 22 percent, which you may find a bit low, but actually, it has improved a lot over the last few years.

The higher the efficiency of a solar panel, the more kWh (kilowatt-hours) of energy per watt of power capacity. A solar panel that is more efficient is going to generate more electricity than a solar panel of similar size and power rating. Buying an efficient solar panel becomes even more important if you don’t have much space on the roof where you want to install the panel. At the same time, you will save a lot on the energy bills as well.

Temperature Coefficient

While solar panels are meant to absorb the sunlight and convert the sun’s energy into electrical power, but too much of anything is bad, and this is true for solar panels as well. The temperature coefficient quantifies as to how much capacity of the solar panel will decrease at temperatures that are higher than 25 degrees Celsius or 77 degrees Fahrenheit. The solar panels are tested in industries at this temperature.

Warranties & Guarantees

While buying a solar panel, it is always better to pay attention to the warranties and assurances given by the company. Warranties and assurances on solar panels are not the same as that in other products because the power of solar panels decreases with time, with the most prominent decrease coming right after the first year. This decline in the power production of solar panels is called ‘panel degradation’.

Many manufacturers offer power production warranty in which they assure customers of the power retaining capabilities of their solar panels. If you see the power-producing capacity of the solar panel to be 80 percent after 25 years of use, then that’s the product you should buy.

When it comes to degradation rate, you will find some manufacturers giving a guarantee of about 0.7 percent drop in the production of power after a year. The smaller the percentage, the better is the performance of the solar panel.

Manufacturers also offer a warranty on the materials against any manufacturing defects, durability issues and environmental issues. These days, solar panels come with a warranty period of 10 to 12 years. 

Final Words

Getting a solar panel should be at the top of your list because a solar panel can help you get an alternative source of power, plus you can save money at the same time, as there is no running cost of these panels. Just pay the money at the time of purchase and enjoy free electricity for a couple of decades or even more. Pick the best solar panel from the above-mentioned list of best rated solar panels consumer reports and start generating your own electricity at home.
