Given the prices you pay and the low cost of solar it seems like it would make a lot of sense to install panels wherever possible. There are over 8k hours in a year and solar typically yields about 20% of nameplate capacity in a year, so perhaps 2kWh/W. If you installed 1kW of panels you could expect to get 2000kWh of electricity. At $0.25/kWh * 2000 kWh = $500 and that's about what it would cost to buy 1kW of panels. So your project, if installed cheaply enough, could probably pay for itself within two years!
