Pricing in solar is typically measured in dollars per watt w and the total wattage of your solar panels plays a significant part in the overall cost of your solar system.
The average cost of installed residential solar power systems is currently 2 60 per watt a typical 6kw system costs 11 544 after claiming the 26 solar tax credit.
Prospective solar panel owners usually have a goal for how much energy they want to produce.
The grape solar 600 watt off grid solar panel kit the grape solar 600 watt off grid solar panel kit is ideal for a variety of applications including rvs boats 12 volt battery charging small pumps charging small electronic devices and operating led lights.
However if a homeowner is trying to buy one or two panels on their own for a small diy project they will likely pay closer to 1 per watt.
So if you have a 250 watt panel you need to multiply those watts by the amount of usable sunlight your roof gets in day.
