LED lights use 85% less energy than incandescent or halogen bulbs

How to make your solar energy go further during autumn

As the leaves start to fall you’ll be looking for ways to keep your power bill steady. While it’s normal for power bills to increase slightly during the colder months as we use more energy to stay warm, there are ways in which to reduce the impact.

Below you’ll find some of our favourite tips and tricks to help keep yourself and your home warm and cosy in the months to come.

Stop heat from escaping  

Even if your home’s well insulated, warmth can still escape out through gaps and cracks – taking your energy savings with it.

Weather-sealing your home is one of the easiest and cheapest ways of reducing heat loss. To seal your home you can install draught stoppers, check fans or vents for gaps, and use sealants to make sure your doors and windows are properly sealed. You’ll be much warmer, will make the most of the energy in your home and won’t feel any draughts coming through. This article has some great ideas to get you started. 


With shorter days your lights will be on longer. If you can, replace any incandescent light bulbs with LEDs. LED lights use ‘85% less electricity than traditional incandescent or halogen bulbs and can last 15 times longer’. So, not only will your lights use fewer kW, but you also won’t have to replace the bulbs as often. And while it may be a little more expensive up front, in the long run, it is more cost-effective and creates less waste.

Adjust the temperature 

Often when it gets cold we tend to crank the heating up. But, running your heat pump at a more moderate temperature, say 21℃ instead of 26℃, uses 50% less power.  So, if you have a heat pump, maintain a moderate temperature of around 20-22℃ and turn it off when you’re not at home. If you want your home to be cozy when you come home from work, it’s best to install a timer that will turn it on before you get home.

And, if you’re going to run your heat pump during the night it’s recommended to turn it down to 16-18℃ as the optimum sleeping temperature is actually around 18℃.

Now is also a great time to get the filter on your heat pump checked. If the filter is clogged it won’t run as efficiently as what it has been designed to.  


During the colder months, some of our appliances see a little more action - like the clothes dryer. 

Choosing the right appliance can make a significant contribution to keeping your power bill low. If you’re on the hunt for new appliances look for ones with higher energy star ratings. This indicates that they’re more energy-efficient and are less costly to run.

As a first step, we recommend you check out the mysolarZero store. You’ll find a range of energy-efficient Panasonic appliances (including clothes dryers) at prices exclusive to solarZero customers.

Even if your appliances do have high energy star ratings, make sure you’re using them correctly. Use a cold water wash where you can, and don’t leave your clothes in the dryer longer than they need to be. And, when they’re not in use turn them off at the wall as many appliances draw power in standby mode.
