Summary

Professor Lisa Ryan from UCD explains the recently approved plug-in solar panels, which are small, portable units designed for balconies or gardens. She details their limited output of 300 to 800 watts, noting they are best suited for apartment dwellers or those working from home who can utilize the energy during the day. While these panels can reduce electricity bills by 10 to 15 percent, Ryan advises that homeowners with gardens are better off investing in larger rooftop systems that qualify for government grants and battery storage.
