Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| DIY solar panel installation is always cheaper than hiring a professional. | While it may seem like DIY installation would save money, there are many factors to consider such as the cost of equipment and potential mistakes that could lead to costly repairs or replacements in the future. Hiring a professional can actually be more cost-effective in the long run. |
| Installing solar panels is an easy task that anyone can do with minimal knowledge or experience. | Solar panel installation requires specialized knowledge and skills, including electrical wiring and structural engineering. Attempting to install solar panels without proper training and experience can be dangerous and result in damage to your property or injury to yourself or others. |
| Professional installations are always better quality than DIY installations. | While professionals have extensive training and experience, not all professionals provide high-quality workmanship or use top-of-the-line materials for their installations. It’s important to research potential contractors thoroughly before hiring them for your project. Similarly, some DIY installations may be of high quality if done correctly by someone with sufficient knowledge and skillset. |
| All homes are suitable for solar panel installation regardless of location or orientation towards the sun. | The amount of sunlight received by a home varies depending on its location, orientation towards the sun, shading from trees/buildings/other structures etc., which affects how much energy will be generated by installed panels over time . A professional installer will assess these factors before recommending whether installing solar panels makes sense for your specific situation. |
| Solar panel warranties cover any damages caused during installation regardless of who did it (DIY vs Professional). | Most warranties only cover defects in manufacturing rather than damages caused during improper handling/installation/maintenance etc.. If you choose to install solar panels yourself instead of hiring a professional installer , you risk voiding any warranty coverage should something go wrong down the line due to improper handling/installation/maintenance etc.. |
