Electric cars like the Nissan Leaf could be a real game changer.  After crunching some numbers, I calculated that the cost per mile driven in a Nissan Leaf could be noticeably cheaper than a comparable gas vehicle.

This is an exciting development for the solar industry since you can produce the electricity for driving your electric car with a solar PV array. This makes electricity a more significant competitor to oil and could help increase solar implementation rates for consumers.

I ran the following calculations on the cost to drive 10000 miles per year in an electric car compared to a 30 mpg gas engine car.  Here are my findings.

Shade mitigation products like micro-inverters and energy maximizers are the hottest new products in solar.enphase

Enphase micro-inverters provide a convenient solution for dc-ac conversion, shade mitigation, and module level power production monitoring.  Micro-inverters convert DC to AC power at each and every module in the array.  This eliminates the difficult process of string sizing and reduces the problems related to more dangerous high voltage dc strings.

tigoThe Tigo Energy Maximizer dc-dc power optimizer offers shade mitigation, module level mpp tracking, module level production monitoring and they work with any string inverter (SMA, KACO, Fronius, PV Powered, Xantrex etc..).  An additional important benefit of dc-dc power optimizers is they cut the string voltage down to module level voltage if the AC power is lost.  This means that when your main breaker is off, the high voltage strings drop to module level voltage making pv system servicing easier and safer.
