How to calculate the number of kilowatts your solar panels produce?
Let’s plug it all in: To figure out how many kilowatt-hours (kWh) your solar panel system puts out per year, you need to multiply the size of your system in kW DC times the .8 derate factor times the number of hours of sun. So if you have a 7.5 kW DC system working an average of 5 hours per day, 365 days a year,…
How much does a 5kw solar panel cost?
The cost of increasing the size of the system to 5kW is only $657 per kW. If we assume that you receive a feed-in tariff of 11.1c for every kWh you export back to the grid, it will only take 4 years to pay back the extra 2kW; this is assuming that all of the additional solar power output is exported back to the grid.
