Default need suggestion on my first solar project

Hi guys,
This is my first project, and i need suggestion on it.

I already have 12 PV modules. And this is the spec of it:
Pmax = 50 W
Voc = 21 V
Isc = 3.23 A
Vpmax= 16.8 V
Ipmax = 2.97 A

I want to build a hybrid system of this project.
My loads consumption is 360 Watt used for 12 hours per day.

Based on my calculation, total watt hours per day is 4320 watt hours. Lets say the inefficiencies factor is 1.5, so the minimum energy of solar panel must produce per day is 1.5 x 4320 = 6480 watt hours.

The average sun hours in my location are 3-5 hours. Letís put 3 hours as the worst case. So, the minimum solar panel wattage is 6480 / 3 = 1440 watt.
But my existing PV panel only can produce 600 watt.
If I scheduled to running generator every 2/3 days a week, do I still need extra panel to supply my loads?

Please, give me solution on this condition.

thanks,

HI,

Consider getting a pair of honda EU1000 generators. They are "inverter" style generators, and have a small gasoline engine, that spins a high voltage alternator, which is rectified to DC, and inverted to 120VAC. They can run 800W, and have an "eco-throttle" which slows the engine down to match the load. They will use a LOT less gasoline, and then there are regular oil changes and other maintainance items. Use 1 for a week, then change and use the other one for a week. Gives you time for an oil change while the other one is running, and you have a spare.
They are not cheap gensets, but should last a year of heavy use. (split between 2 units) Less cost than PV panels.

So you’re suggesting him to run a combustion engine for a year??
Not at all being confrontational, but .. Cost is cheaper? I don't see how.....

How much would gas cost all year? Not to mention it kind of kills the whole reson we try alternative methods for energy.

Hey.... Do you work for the OIL Company?
