ᐅ Do photovoltaic systems and heat pumps share similar performance characteristics or operational experiences?

Hello dear forum members,

Since Monday afternoon, my photovoltaic system has been up and running, and I have to say... I can’t stop smiling.

Here are the details:

• 5.4 kWp (18 modules at 300 W each)
• Peak power limitation 70% soft
• Flat roof, mounting angle 10°
• Orientation southwest, about 45° off south
• Feed-in to household electricity including heat pump
• Surplus energy sale
• no battery storage

Today’s performance:

The gray line represents household consumption, the blue and red areas show production, where the blue part was self-consumed and the red part was sold.

You can clearly see the washing machine running in the morning, the regular starts of the heat pump, midday consumption, and even the not-so-optimally started dishwasher after 6 p.m.

For a (very good) day in March, I’m more than satisfied. The only thing is that the heat pump in the early morning isn’t yet running as efficiently as I’d like. But I guess only a battery would help with that, and that still seems uneconomical to me.

How much did the whole project cost you?

The investment amounted to 7,900 euros net or 9,400 euros gross. So, even small cars are more expensive.

That's still manageable. Local supplier? Or through the photovoltaic forum?

A relatively local provider, but originally found through the mentioned forum.

It was quite an expensive offer, even though these are not "cheap modules." Or are there any special circumstances in your case?
