How to make your home solar system smarter and reduce power bills – Interesting Engineering

Again, they can be programmed to heat water at times of peak solar generation and store it, thus providing almost free hot water when needed.

Many other smart appliances and lights are available. Induction cooktops deliver fast and impressive results using little electricity. Along with the microwave, air fryer and pressure cooker, they can reduce energy use. Ovens and slow cookers can be programmed to use solar power and have meals ready when we get home.

As well as having options with high star ratings, appliances to wash and dry clothes and dishes can easily be set to run during sunshine hours.

Energy-efficient fridges also cut costs. However, while people are happy to buy such fridges, our research survey found some keep the old one, using three to four times the electricity, for drinks.

Homes with swimming pools or spas are notorious for having the highest electricity bills. A pool will typically use 2,000-3,000kWh of electricity per year (depending on type of pump, hours of use and whether the pool is heated), at a cost of A$700-1,200. Solar pool heaters are an excellent alternative. A simple timer switch can ensure most power is consumed during sunshine hours.

A typical outdoor spa uses 5kW for water heating and circulating. Much heat is lost to the surroundings if you let the thermostat keep it warm all the time. By installing a timer switch, you can use solar power for heating and have the spa ready for use after working hours.

Use smart technology to control time of use

The key to making the best use of your solar output is avoiding energy wastage and matching the timing of energy supply with household demand. An affordable smart control system – for the whole home or individual appliances – can do this.
