Do THIS to make the most of your solar panels and heat pumps

The amount of solar technology available to us is growing exponentially, and as we work in tandem to save the planet, our tech can work together too! Today Charlie and Josh are taking a look into the awesome combination of solar panels and heat pumps, to see how to make the most of your technology.

How did you work out the required heat pump power for 5.2kW? If a heat pump of 9 kW to be used, it shouldn't draw more than 2 to 2.5 kW electricity assuming a SCoP of 3.5?

Do these calculations factor in buying cheap nighttime electricity on a flexible tariff?

If these cost estimates are anywhere near real I fear for the entire alternate energy future in Britain. They are very far from cost effective indeed. Fortunately, at least where I live in Canada the costs are dramatically lower and a solar powered heat pump is more affordable. My home is relatively small at 150 sq meters, but my costs for a DIY install of a 2400 BTU heat pump, ten 250 watt solar panels, a 2000 watt online UPS and 48 volt 100ah LifePo4 battery + charge controller. - total cost about 4500 British pounds. The savings compared to the preexisting baseboard heaters is almost 700 pounds a year. That's a 6 year payback, easily covering a small add on to the mortgage. Professional installation by an HVAC installer would have added at last a third more - but still a bargain compared to those UK prices. To add icing on the cake, a federal government heat pump rebate program cuts the cost in half.

You can buy battery for 1500-3000 euro, also my solar installation cost 7k last year. Are you supporting dezinformation?

[Agatesforbrains]

Don't without the battery and set the heating colling to jump up at the end of the day, and then idle for as long as possible at night.

Great work🤌
If you go DIY the battery and panels the costs are so very much lower. 😵
The current costs of the panels is less than £200 per KW, so £5k will can you do panels and mountings + £5k for a hybrid inverter and Battery & wiring.

Guys what about just salt panels plus heat pump and no battery - roi? How many years roi? Better idea than having a battery too?

[andycampbell]

£20k for a solar installation is completely ridiculous. About £7k is closer.

Why are you talking about number of panels as if the output of panels is a standard? The company I install for has panels ranging from 370W up to our latest 750W Longi panels. Number of panels is irrelevant! Array output size is what matters...
I almost fell off my chair when I saw the prices you guys were quoting. Solar is soooo much cheaper in Australia.

This video basically doesn’t acknowledge the idea that dc compressors exist…

You can now buy dc heat pumps that drastically reduces consumption… more then halving the use of solar panels to power a heat pump…

I’d rather wait until someone does the video demonstration of such units then watching old technology being lifted by renewable energy…
