Energy Efficient Appliances
The first thing you should do before you by your solar system is calculate the solar power needed to power your house. Figure out which appliances are not energy efficient and upgrade them or switch to propane or natural gas in order to reduce how big of a solar system you need.
You can use our Solar Cost Calculator to figure out your current consumption or get a rough estimate using average values in our appliance power table or measure the actual power usage of each appliance with a Kill A Watt Meter. The Neurio Home Energy Monitor also gives excellent real-time monitoring of your energy usage.
Appliances can be one of the greatest consumers of electricity in a household, but air conditioning and heating are usually greater and benefit the most from upgrading to energy star efficient systems.
