How much will a 8kW solar system produce?
A 8kW Solar Kit requires up to 460 square feet of space. 8kW or 8 kilowatts is 8,000 watts of DC direct current power. This could produce an estimated 500 to 1,400 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South.
Is a 8kW solar system enough?
So let’s go bigger and see what an 8kW solar system can do. It would have an average output of 33 kWh per day which would be enough to do three loads of laundry with a standard washing machine and electric clothes dryer, one load of dishes in the dishwasher and keep the hot water heater going through it all.
How much does a whole house solar system cost?
With installation, an average residential 5kW size system costs between $3 and $5 per watt, according to the CSE, which results in the $15,000 to $25,000 range. That cost is before any tax credits and incentives. If you know your current energy usage, you can calculate how much you’ll need to pay for solar panels.
