Solar Hybrid Geyser System
The Solar geyser uses natural sunlight to warm the water in the pipes and transfer it back to
Energy consumption analysis

In our situation, the geyser in Sept (Spring) gets to 70 degrees in the afternoon and reduces to 30 degrees after everyone has showered and bathed, meaning it is reducing the electricity power consumption of the house by 10kwh per day. In the high pressure solar geyser, the water in the storage tank is only use to store heat and is not consumed. This means it is suitable for situations where the geyser might encounter temperatures below zero over night as an antifreeze can be added to the geyser water.

The following graph shows the electrical power used by two geysers that use the preheated water from the high pressure solar geyser system. The electric geysers are a 200 litre and a 100 litre system. In South Africa in Johannesburg there is a ripple relay control system that allows the municipality to switch off the geysers remotely during peak loads. This typically happens between 18h30 to 21h00 and from 07h00 to 09h00. The graph shows that for 3 adults 7.26kwh of electrical energy was used to heat the geysers in one day. This situation occured before the load scheduling program was implemented detailed below.

Overview

A solar water heater is a renewable energy system that uses sunlight to heat water for various domestic, commercial, or industrial applications. It typically consists of a series of rooftop collectors that receive solar energy and send it where it’s needed in the building. Some heaters also incorporate heat transfer fluid that transfers energy throughout the system and a continuously heated water storage tank.

Because solar water heaters do not depend on electricity and take energy directly from the sun to heat stored water, they often save homeowners money on electricity costs. . Energy from the sun doesn’t cost anything, of course, so no charge from electrical utilities is needed.

A lot of energy is used to heat water in our homes. In fact, according to the US Energy Information Administration, about 12% of home electricity consumption goes towards heating water. The good news is that switching to a home solar water heating system can reduce energy usage and associated costs.

How It Works?!

It has been argued that expanding use of wind power will lead to increasing geopolitical competition over critical materials for wind turbines such as rare earth elements neodymium, praseodymium, and dysprosium. But this perspective has been criticised for failing to recognise that most wind turbines.
