Making it possible for every roof to have solar
Rooftop solar in a crowded city like Benguluru isn't always easy to integrate. With a huge population to accommodate, sprawling roof south facing rooftops are not always available for aspiring solar system owners. Luckily, Enphase microinverters makes it possible for homeowners with limited space to make an economically sound and environmentally beneficial solar investment.  Vishukumar Shetty, a resident of Bengaluru, had a difficult rooftop with two main elevated areas for solar. One is a four-sloped tiled surface, with only space for one panel on each side, while the other is a flat roof with space for only four panels. By giving each panel its own microinverter, Ecosoch Solar achieved the installation with much neater and safer cabling with only low voltage AC running through the system instead of a mess of high voltage DC cable.

Different orientations and positions cause panel performance to differ up to 30% at different times of day as the sun passes over the system.

Each panel performs at it's best
A complex rooftop with different orientations can also be an obstacle to overall system performance. This is because each panel would only be able to perform as well as the lowest performing panel at any given time, if the sun is not shining on every panel, it might as well not be shining on any of them. For the Shetty system, the difference in performance between panels can be as high as 30% at certain times of day, meaning that certain panels in the system would be performing 30% less than their actual potential output. Ecosoch overcame this challenge with Enphase Microinverters, allowing each panel to perform individually, unaffected by the lower performing panels in the system.

 

Because DC to AC conversion happens at the panel with the microinverter, the cables running across the roof of a complex installation like this are much safer.

Peace of mind for the homeowner
The huge benefits of this technology don't just stop with better performance. Bengaluru's dust-prone city climate is a major roadblock for solar systems, requiring careful maintenance to ensure optimal system performance over time. By including per panel monitoring into his system, Vishukumar ensures he doesn't allow system issues to go long without being detected. Without reliable system monitoring, system owners can lose out on large chunks of performance without realising it.

With 15-minute incremental data on the performance of the system monitored by each microinverter and uploaded by the Enphase Envoy, Vishukumar can easily find and isolate any problems in his system. When it comes time for maintenance to fix these problems, or just a general panel cleaning, the clean design of the microinverter system makes safe and easy access to each panel easy for the installer.

Despite spatial constraints, EcoSoch Solar has used Enphase Microinverters to achieve a high performing result on the Shetty rooftop. With hardware that thrives in otherwise difficult orientations and positions and software to prove the system's performance, Vishukumar can be confident in his system choice, especially when he has award winning monitoring software to back it up.
