Hi all, was looking some advice on using a solar panel to heat water through summer months.
Instead of a large PV arrangement I was hoping to buy a single panel that could output max 250w, and connect it directly to water heater via change over switch.
My immersion heater is rated at 2500w and takes around 30mins to heat water, if It was feed at only 10% which is the 250w solar power then would it be capable of heating the water in 5 hours?
I calculate that it will take 10 times longer at 250w, so 30minx10=300/60= 5hours, could this be possible??
Also the sole purpose of panel is only to heat water, so no need for an inverter.
Appreciate any replys.
