What are the performance benefits of upgrading an existing solar system with high efficiency solar panels?

Several years ago, the homeowner installed a small 1.5-kilowatt solar panel system costing around $3,000. However, the system was outdated, less efficient, and generated lesser output. Recently, they decided to upgrade and purchase new panels that were twice as powerful, efficient and reliable. The new panels were installed on the more efficient part of the roof while the old panels were moved to the less efficient part, providing a combined output that has been working tremendously.

The homeowner decided to spend more on the new panels to have a quality product that they can trust. The new panels, together with a power wall, made them 100% self-sufficient energy-wise, working seamlessly even when there is a power outage. They don't even notice when the power goes out in their street, making the investment in quality solar panels and power wall worth it.

Yes we initially did have a system put in about several years ago. Just a small system it was 1.5 kilowatts, but it was a start for us. So, yes. Yeah, it was about $3,000 for the system at that time. The new panels are probably twice the power of the old panels, and only maybe marginally 50% bigger. So we'd get a greater output from the same size space we've got on the house. They're probably twice the efficient and we're getting more power out of the sun. So we had the old panels sided to a less efficient part of the house, the roof. And then, so we've got the new panels on the more efficient part of the roof, and fantastic. So we've got combination of the old and the new and it's working tremendously.

We decided to spend more on our panels this time because we wanted something that we could trust. We wanted something that was reliable, and yes, we decided that we just wanted quality panels. That's as well as the brand name it's also the performance as well. So we just wanted to have quality product. Since we've had new panels installed and the power wall, we've been 100% self-sufficient energy-wise. That's all worked tremendously, it's been seamless. You know, if the power goes out in the street, we can see the powers go out in the street. We don't even notice it at home. It just completely kicks in.
