Professional Buying Advice for Solar Panels


Buying the best solar panel of 2018 is a daunting task, considering that the market’s filled with countless varieties. With so many available options, any customer can end up feeling baffled. We’ve decided to give you a helping hand, which is why we have put together a short yet informative buying guide, which will hopefully allow you to correlate your needs with the features you might be looking for in a solar panel. Here’s what you should know.

Best Solar Panel

Cost and efficiency

Solar panels can be made with different materials and they come in various shapes and sizes, but one of the first things to consider before starting to research the market is what you’ll be spending. Carefully set a budget not only for the actual panel but also for what its installation will cost you.

While the price of solar panels can vary greatly depending on the manufacturing brand, quality and type of materials employed in their construction, efficiency should be at the core of a prospective buyer’s decision.

After all, these items are made for reducing energy usage, so a cheap, unreliable model will do nothing for you, because it will likely break down and thus force you to spend even more money on another new and expensive panel, which will also need to be installed by a professional.


Expected energy usage

Yet another detail to consider when it comes to purchasing solar panels is the energy need of the building you’ll be installing them on. If possible, try to estimate your energy usage by examining all the utility bills that you’ve had to pay in the course of the last year. Sometimes, it’s wiser to choose a system that will produce a bit more energy than what you actually require, just to be on the safe side.



If you’re no expert in the art of choosing these kinds of products, you might want to check with some of the best solar panel reviews. Past customers will let you know just what to expect in matters of reliability, convenience and affordability, and most of these individuals will likely emphasize the durability of the unit you’re looking to buy.

Renogy RNG-100D


1.Renogy 100 Watts 12 VoltsRenogy has been on the market for quite a while now, so the brand’s well-known for manufacturing top-quality products. This is the same case with this variety, which can be purchased as an expansion kit and in packs of 1 to 6 panels.

In fact, approximately 85% of the people who have purchased the model were so satisfied with its quality that they awarded it a 5-star rating.

Eco-Worthy L02M100-1


2.Eco-Worthy 100 Watt 12 VoltThis is a monocrystalline photovoltaic PV solar panel module that is somewhat comparable to the model we’ve showcased above. The main difference between the two stands in the price and in some extra safety features of this Eco-Worthy one. For example, unlike the Renogy unit described earlier on, this one comes with reinforced safety and anti-reflection coated glass, which is 3.2-mm thick.

The frame is made with aluminum, as is the case with other products in the line. The panel can withstand both snow loads and high wind, and is relatively well-known for being both durable and dependable.

Depending on the available sunlight, the Eco-Worthy variety is capable of providing around 500 watts per day.

This model can be utilized for 12V battery charging and can be wired for 24V battery charging.

Let’s see what customers had to say about the Eco-Worthy solar panel. Although it might not be the top rated panel on the market, it still has managed to gather close to 80% in positive reviews. People state that the item offers great value for the price, particularly since it’s well-constructed and able to produce 5.7 amps on bright days. The product is so good that it even manages to produce some energy in low light.

3.ALEKO SP20W12V 20WIt would have been impossible to leave out the Aleko model from this list, as it is one of the most affordable panels we’ve stumbled upon. While most online marketplaces sell it for around one hundred dollars, Amazon customers can often get it for sale and purchase it for half the price.

This unit has an operating voltage of 175V, an operating current of 114A, and an open circuit voltage of 220V. It can be used for 12V battery charging, considering that it has the nominal output voltage of 12V.

This is a monocrystalline panel, as is the case with the two others we’ve mentioned above.

The frame of the product is made with aluminum and the unit has been tested and proven to perform well in the case of hazardous weather.

Since it’s manufactured in China, it hasn’t gathered as many positive reviews as the Eco-Worthy or Renogy models, but customers still claim that it offers good value for the price and that it does what it is supposed to do. The main issue that some individuals have run into is related to the warranty service, as returns and refunds are somewhat difficult considering the country of origin of the product.
