Our Comprehensive Buying Guide


Searching for the best solar panels out there can be a bit tricky, especially if you are a novice and you do not know what features are important to consider. To help you out, here is a list of aspects that you should not overlook before making a purchase.

Consider your needs

If you are thinking of buying an expensive or cheap solar panel, you probably need an alternative energy system that you can use to operate the electronics in your home or RV. Therefore, one of the first things that you should determine is the amount of energy that you need the panels to produce.

Additionally, you also need to think about the overall system capacity and the budget that you are ready to invest in sunpower solar panels.



If you have read solar panel reviews before, you probably know that there are three main types of devices that you can select from. Monocrystalline panels are regarded as some of the best options currently available because they can provide users with outstanding energy efficiency.

These choices are manufactured out of pure silicon crystals. Most of the monocrystalline options that you can find for sale are black and they feature white aluminum frames.

The second model that you can opt for are solar panels made of polycrystalline, a mix of various silicon crystals that have been melted together. As expected, these products are less efficient and, at the same time, less expensive than units made of monocrystalline.

Because of the result of the mixture of different types of silicon crystals, polycrystalline panels have an easy to recognize blue shade.

Finally, thin-film panels are also made of a combination of materials. In this case, the panels are manufactured using a mixture of cadmium telluride, Copper Indium Gallium Selenide and amorphous silicon. The one aspect that differentiates them from the alternatives is the fact that they are not as solid and not as energy-efficient.

However, one advantage that you should consider before making a decision is that thin-film panels are the lightest of the three choices.

Inverter efficiency and mounting hardware

If you have ever taken a close look at a solar panel review before, you probably know that each device of this sort comes with a power inverter box that is placed between two or more panels. This box works by converting DC energy into AC energy, that you can efficiently use in your home to power your electronic devices.

However, one thing that you should keep in mind before you select the best suited solar panel for your needs is the fact that not all inverters are constructed equally. In other words, the efficiency of an inverter depends on the amount of energy the device uses to convert DC to AC energy.

Apart from this aspect, before you make up your mind and purchase a product, you also have to consider whether or not the affordable solar panel that you like is simple to set up.

Most solar panels for home that you can find come with pre-drilled holes that make it easy for you to install them on the roof of your house or RV. Still, many of the units that you can find do not come shipped along with the necessary mounting hardware.

This means that you have to spend extra time and money looking for a good mount that works with the sunpower solar panels that you have selected.



Frequently Asked Questions:


Q: How many solar panels do you need?

According to the specialists, an average homeowner needs to purchase and install between 28 and 34 solar panels to make sure that he/she gets the needed energy. One aspect that should not be overlooked is that the number of panels that you need for a home might also depend on extra factors such as the performance of the panels that you select and their location.

To get a good understanding of the amount of energy that you use and, thus, will need the panels to generate, you have to look at the number of kWh of electricity you utilize in a year. One study from 2016 found that one USA citizen uses around 897 kWh every month. To put this into perspective, that is around 11,000 kWh per year.

Besides, the amount of kWh that a solar system can produce depends on the amount of sunlight exposure that it gets.

Q: Are solar panels worth getting?

Given that solar power costs somewhere between 5 to 6 cents per kWh to produce, it can be argued that investing in a system of this type is a no-brainer decision. On average, the system pays for itself in around 3 to 4 years.

However, before you decide to make the transition, it is vital that you take the time to think about several extra factors. For instance, buying solar panels and all the extra mounting equipment can be quite draining on your savings. If you do not live in an area that gets the needed sunlight exposure, chances are that you won’t be able to capitalize on the initial investment.

Furthermore, to use a solar panel system you have to dedicate some of the space that you have available to set up the panels. This process can be a bit time consuming as well as challenging, because these devices cannot be installed in areas near your home that do not get optimum sunlight exposure.


Q: How do solar panels work?

If you have read a solar panel review before, you probably have a basic understanding of how these devices work. To put it in simple terms, a solar panel operates by allowing the particles of light, also known as photons to generate a flow of energy by knocking off electrons from atoms.

The conductors that are attached to the cells can help create an electrical circuit. Once the electrons flow through this circuit, they actively generate electricity. A solar panel is made up of multiple cells. These cells are manufactured out of semiconductors such as silicone. These solar cells are constructed similarly to a battery, as they feature a negative and a positive layer. Furthermore, multiple modules or panels are wired together to create a solar array.

If you set up multiple panels, you can generate more electricity than you can later on use to power the electronic devices from your home or RV.
