Enjoying cooler summer with electricity bills down

The home rooftop solar project using Hoymiles microinverters in Madrid has started to enjoy lower electricity bills and cooler summer.

The only thing to note is that to achieve the best solar yields, the installer separated the panels into four and two which were put on two orientations of the roof. But this is not a problem with microinverters since each solar panel operates on its own without affecting the others in the array. Moreover, the HMS microinverters used in this project come with independent MPPTs (Maximum Power Point Tracking), meaning that each panel produces power at its maximum power point. This maximizes the solar harvest of the whole system.

Specifically, the HMS-1500 microinverter used in this project comes with four input channels which are connected to four solar panels respectively (what we call the 4-in-1 design). The HMS-800 has two input channels (2-in-1) which link to two panels. Thanks to this flexible design, it was possible to split up the six panels deployed on the roof. With this compact design, users no longer need to install multiple microinverters for each panel and thus save more on up-front costs.

By installing this rooftop solar system, the family has already seen a decrease in their electricity bill. This can be especially helpful during the peak months of summer when the air conditioning is running nonstop.

For years to come, they will see the solar system paying itself back. It's clear that by adding solar to their home, the residential customers have taken huge steps to become more sustainable energy consumers. They saved money on their electricity bills, reduced their carbon footprint and most importantly, moved closer to a clean energy future.
