& Growing

The US now has over 8,500 MW of

solar power capacity, enough to power more then 13 million

homes!

What is fueling the growth

Great incentives (Missouri with the best incentives in the country right now)

Energy costs escalation

Solar module costs have plummeted in last 2 years (Cost have leveled out and we are seeing price increases due to the tariffs the US has imposed China)

Aesthetics improved

Massive growth in interest, mainstreaming across US

PVWatts Actual Performance vs Prediction

The performance of nearly 650 solar installations is compared to PVWatts predictions. Enphase sites are shown in orange, standard inverter sites in grey.

Maximum Performance Enphase Microverters are installed beneath the solar modules on the roof, and they convert the maximum power from each module into standard AC electricity.

Enphase Microinverter

Worlds most efficient microinverter

Supports low-light and low-voltage operation

Innovative cabling for fast and easy installation

Simplified Networking The Envoy Communications Gateway monitors the health and performance of each microinverter and solar module, and it sends this information to the system owner and installer via the Internet

Envoy Gateway

Plug & Play setup

Communicates over existing electrical wires

Connects to standard broadband router

Advanced Monitoring The Enlighten web-based software provides system owners and installers with detailed performance information and analytics about the solar system, as well as at-a-glance views and automated alerts.
