Solar panels may be on top, but it’s the inverter that does all the real work. The solar panels on your roof absorb sunshine in the form of direct current (DC) power. The inverter converts that DC power to alternating current (AC), the form of electricity your home can use. The two types of inverters we commonly use are micro inverters and string inverters. The efficiency of your inverter is much more important then the efficiency of your solar panels. For this reason, we have partnered with some of the world’s leading advanced technology providers.


Enphase micro inverter systems are the next generation of inverter technology. They are consistently outperforming other systems by 20% and offer the flexibility to handle whatever the future might bring—from home expansions to smart home and smart grid integration. Enphase micro inverters are 100% battery ready, easily expandable and are much safer then conventional central inverter systems.  Consumption monitoring is offered as a standard option with an Enphase system which allows managing your energy usage and shifting loads a dream. The Enphase S270, IQ7 and IQ7+ are now available and is the perfect choice for Your 25 year solar investment.
