In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel.
30 kwh per day solar system.
It generates averagely 120 units to 160 units per day electricity.
This is assuming that all of the additional solar power output is exported back to the grid if you self consume the power it will pay back.
30kw or 30 kilowatts is 30 000 watts of dc direct current power.
Likewise if you wanted to account for 100 of your daily kwh consumption you would need 30 solar panels 37 kwh daily usage divided by 1 24 kwh per panel.
This could produce an estimated 3 000 to 4 000 kilowatt hours kwh of alternating current ac power per month assuming at least 5 sun hours per day with the solar array facing south.
A 30kw solar kit will require over 1 800 square feet of space.
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.
30kw solar system a 30kw system will require at least roughly 180 250 m2 of area for installing.
The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map.
And lets also assume there is a 15 energy loss with the inverter converting the power from dc to ac.
How to calculate your own solar panel estimate for those wondering how we estimated those numbers for energy consumption and required number of solar panels here s the breakdown.
We also assumed that the average household consumes about 10 400 kwh per year and the panels we re using are 250 watt solar panels.
To provide an actual real life example to the 30 kwh per day of electricity production from solar lets assume the location gets 5 hours of sunlight per day with no shading and a perfectly optimized angle of the panels towards the sun.
Next figure out the average amount of sunlight you get per day.
Fast payback on additional kws.
If you re going by the national average then you should be using about 30 kwh per day.
