I think it would be wise to not waste any energy whether it’s free or paid. Every electronic item has a limited working lifespan, if you were to run it all the time, it’s gonna break very soon. Aside from few selected electronics, nothing is built to run 24×7. And if your solar panels are producing that much power that you’re thinking of wasting then it’s better to sell that “Extra” power back to the power company and earn bucks monthly. This is called Solar Net Metering. If you still want to waste energy then the short answer is “Yes”. You can waste as much as you want since you own this energy.
