But that doesn t mean that the tesla solar roof is the best way to go solar.
Cost for one solar panel vs power.
For example if two solar panels both have 15 percent efficiency ratings but one has a power output rating of 250 watts and the other is rated at 300 watts it means that the 300 watt panel is about 20 percent physically larger than the 250 watt panel.
With the average solar panel costing about 0 64 per kw in 2016 at this rate you can then expect sunpower solar panels cost per watt to hover around 1 12 175 of 0 64 to 1 28 200 per kw.
Comparing the top renewables.
