Besides, how many solar panels do I need to run a hot water heater?
One solar panel would be enough to power a traditional storage hot water heater throughout a day as this is the most inefficient appliance used in most homes.
Secondly, can I heat water with solar panels? Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water which is stored in a hot water cylinder. A boiler or immersion heater can be used as a back-up to heat the water further to reach the temperature you want.
Additionally, do you need solar hot water if you have solar panels?
“For those looking for further cost efficiencies in their home, Solar PV can be used to heat water, you do not need to install specific solar hot water systems, which our study has shown are less cost efficient,” said Ecoelectric managing director Jeff Wehl.
Are solar hot water systems worth it?
Is it worth the upfront cost and will it really save you money in the long run? The short answer is: probably yes. A well chosen solar hot water system (HWS) or a heat pump may cost more to begin with, but they can be significantly cheaper to run than a conventional electric or gas system.
