Buying solar panels can be a tricky experience. You may feel excited about finally going green and improving your building’s energy efficiency. But, at the same time, you’ll have to compare multiple quotes to ensure you’re making a worthwhile investment. 

Fortunately, we have compiled some do’s and don’ts, so you know all the factors to consider while buying solar panels.

Buying Solar Panels – The Do’s 

When it comes to what to know before buying solar panels, here are some do’s that will keep you on the right track:

Buy the Whole Package

This is one of the most important factors to consider while buying solar panels. Typically, when purchasing panels, you need a solar panel system that also includes an inverter as well as a rack system to keep the panels in place (mounting). 

Although solar panels seem to be the most crucial component, they still need the inverter and mounting to function correctly. 

The inverter is essential as it converts DC power from the panels into electricity you can use in your home or commercial building. As mentioned, the rack system keeps your solar panel stable, thus protecting your investment from damage.

Research the Types of Panels and Inverters

To give you a basic idea of your available options, you can buy four major types of solar panels. These are monocrystalline and polycrystalline, PERC, and thin-film panels. Monocrystalline and PERC (Passivated emitter and rear cell) panels are suitable if you have limited space but still want a high energy output. 

Polycrystalline panels are more affordable but less efficient compared to monocrystalline panels. Thin-film panels are made from flexible material but tend to be less efficient than silicon solar panels. 

So, as you can see, there’s a lot of homework you need to do to ensure you buy solar panels with the right efficiency. Also, keep in mind that the efficiency of your inverter matters. An efficient inverter will save more electricity in the long run.

Check Length of Warranty

Ideally, you want to buy your solar panels from a manufacturer that offers a good guarantee. Getting a significant warranty period is often a good sign that you’re dealing with a reputable manufacturer. 

For instance, if the warranty length is over 20 years old, you can buy the product with confidence, knowing that your investment is bound to deliver a substantial return. 

To be on the safe side, buy from companies that have a long history in the business as there’s a higher chance they will still be around to honor your warranty down the line.

Buying Solar Panels – The Don’ts

Besides knowing the right things to do while buying solar panels, be sure to also avoid the following pitfalls:

Don’t Be Swayed By Pricing and Advertising

There are many factors to consider while buying solar panels, but you would be surprised at how many buyers base their decision on price alone. The problem with this is that you may end up buying cheaper panels while sacrificing quality. 

So, it might seem like you’re saving money, but dealing with headaches and hassles down the line is not worth it. For instance, be wary of a company that quotes low prices. 

In most instances, they may source products from a manufacturer with a questionable reputation, or their operations might not be as efficient, resulting in poor quality panels and project delays.

If you can help it, you should also resist high-pressure sales and “too-good-to-true” advertising. Otherwise, it’s all too easy to have impaired judgment if you rush to make a purchase.

Don’t Mix Different Brands

Generally, mixing different solar panels is not recommended. That’s because solar panels that come from different vendors or manufacturers tend to have different electrical characteristics. The performance degradation of each solar panel also varies.

So, even if the solar panels look the same, complications can still arise as long as the brands are different. Always talk to the supplier to ensure you’re buying solar panels with the same current and voltage and which are made by the same manufacturer.

That way, you’ll have peace of mind knowing your investment is protected from damage. You should note that while mixing different solar panels is not the best idea, it’s still possible if you work with a professional who can provide proper guidance about mixing solar panels.
