Solar panels on block of flat roof

[tomtomato]

Hi,

I live in a block of flat, with 33 flats.

The roof is flat, and quite large. I think the usable surface for solar panels would be at least 150 m2.

We pay around £4,000 for communal electricity per year (communal lights, lifts, car park etc). We use around 3,000 watts per hour.

Would solar panels on the roof make sense just to pay for the communal electricity cost?

Thanks,
Tom

There would be a number of factors to evaluate, but possibly.

Just because the roof is flat doesn't mean the panels have to be.

Surely the panels are more effective if they are at an angle?

The middle of the roof is completely flat, so the solar panels could be oriented south and at the optimum angle.

They can be supported to create the desired gradient.
