Straight Heat - Solar Panel - No MPPT!

Hello. This is first video of me testing how to get straight heat from solar panel withouth using MPPT inverter. #diysolarpanelheating #diysolarpanelpoolheater #diysolarpanelwaterheater #diysolarheatingpanels #diysolarpanelheater #diysolarpoweredwaterheater #diysolarpanelheatingand

I frequently run water pumps straight from a solar panel without issues. One factor for light bulbs as resistors it their resistance changes when they heat up, so account for that.

Hello. Yes light bulbs are not good - I am almost ready with second part where I changed tight bulbs for heating resistors. That is why my measurements was so messy. Video will be ready hopefully on Sunday. 🙂

I use direct to PTC heater with dc fan to move the heat

Hello. I was thinking about this. PTC heater resistance increases when temperature increase. so I don´t know how it works when there are clouds and solar panel doesn't give as much power as it should. for example if you have 12V 150W solar panel combined with 150W PTC heater, on full sun it will work, but what is efficiency of PTC heater when there are clouds and voltage on solar panel will drop to 8 volts with only 70W of power output? I am aiming what is efficiency of the system, if PTC heater use all available power of solar panel. Next problem is that I found 12V PTC heaters and I have 30V open voltage- it will burn the fan of heater. So there must be correct solar panel for correct PTC heater or needs to be adding resistor for fan to lower the voltage. But it is interesting to know. Thank you.

One of the other guys on UA-cam put a heater inside of a tank with sand and if heated the sand through the solar panel and warmed his house

Very interesting. I found some videos about this. So sand is slowly releasing the heat for a few hours acting like a heat battery. It is very interesting concept but probably for bigger solar system. On Sunday I am releasing the second video. I am planning to test heating a house with solar panels in autumn and winter. Solar panels will not have enough power to fully heat the house so it will only be like a secondary heating source and because of that I don't need to store heat energy as I need to heat air as much as possible. But with more solar panels with higher output (I guess more than 3kW) it would be good to store some energy for evening release. Very interesting. Thank you for sharing.
