Having electricity only 5h per day you can still try to mine idena. In your situation it would be much better if you could invest in VPS (about $ 5 per month) than you would mine it 24/7 but even without it you can still mine several coins. Unfortunately, when you mine idena every two weeks, you have to participate in the online validation, which is always at 13:30 (UTC time), so if you have electricity in these hours, you can try it.
