Solar system for Gasoline station

[AZlink]

Hello guys, a local gas station asked me about a grid tie solar system, I checked all the bills and almost same amonuy never higher then 2,225 kWh 30 days, working hours are from 6:30am to 8pm, during the day he wishes to run on solar and at night with the grid, any info is aappreciated, thanks in advance AZ

first, he has to find out if Grid-Tie is allowed. Guessing at a 6 hour solar day, the panels should be 3x the daily usage. if he uses 10KW daily, 30Kw of panels (running for 6 hours) would put a pretty good dent in his bill. But the panels will cost a fair amount too, could take 10 years of bill savings to pay for them.

But on top of the station canopy would be an interesting place to mount them. With some racking to give the right tilt.
And it might draw attention from drivers passing by.

If you are installing a grid tied system, you should install a system considering base load for fastest pay back. Keep in mind that some grid tied inverters are sensitive to voltage fluctuations. You should better discuss voltage fluctuations with supplier of inverter.

We got sunlight from 6:15am to 6:09pm, we at the tropical P.R., I was thinking the same about the Canopy and all drivers by will get their attention, gas station is at the #2 road, the road that goes arround the island.......
Grid tie is allowed, actually the electric company says its the only way allowed but found 7 houses off grid this past week they all cut the cables from post to their houses called the electric company to remove the fake and fraud LCD meter that is doing all the over billing...................AZ

I counted 272 panels between the two buildings. Even with only using 250watt panels that is a 68kw system.
