Do you own a flat roof or an sloping roof angled towards south, south east, south west or west. It needs to be more than 20m by 5m, and not shaded.
Have you ever considered solar PV on that roof, in order the transform your business property to be a green business property and potentially increase it’s appeal?
You invest your business savings, and own the solar PV panels. You take all the financial benefit from avoiding buying grid electricity from your electricity supplier; get government incentives for green energy; and export any spare electricity back into the grid for an income. Typically over 20 years, it is like getting a return of say 6% interest per annum from the investment bank, together with other business financial benefits. (this is merely is simplified illustration)
You don’t have savings to invest. You could get a solar supplier to lease the roof space. They would own the solar PV panels and get the financial benefit (because they are using their money to fund the project). You would avoid buying some grid electricity from your electricity supplier. Reducing you overall electricity bill, and doing the right thing for the environment.
