Where Should I Install The Panels?

Installation placement is another critical factor you need to consider. In general, most homeowners have several options on where they can place the panels.

Who Will Install It? 

You may be an avid fan of the do-it-yourself (DIY) movement; however, solar energy system installation isn’t a recommended DIY project. This is particularly true when installing panels on a higher or sloped roof. Thus, consider a solar expert to ensure a proper and safer installation.

As solar energy becomes more common, you can now find numerous solar installers and contractors. Thus, you want to do thorough research. Check their credentials, qualifications, and experience to find the most reputable ones. Also, compare prices from at least three contractors to find the best offer for your budget.

What Is The Warranty For Solar Panels?

As such, when looking for a reliable solar contractor, you want to ensure they carry a good service warranty. If you’re buying panels from a separate supplier, ask the company about the product warranty to protect you against manufacturing defects.


In today’s increasingly eco-conscious world, adding solar panels can be a valuable asset for homeowners, giving you the ability to generate your own electricity while staying on the good side of the planet.

When considering installing solar panels in your home, answer the abovementioned questions first to help guide you through the process and ensure a successful switch.
