A more efficient home

Energy efficiency is not just for older homes. Over four years of home energy evaluation data show that a home's energy efficiency is not directly correlated to its age. Even if your home is relatively new, you could be saving valuable energy and money with some simple steps.


Saves you money on energy bills and is eligible for rebates


Is more comfortable thanks to fewer drafts, better air distribution and less noise


Is healthier because it prevents pollutants and pests from entering


Helps the environment by wasting less energy and requiring less new energy production

All homes can benefit

A home's age has little to do with how efficient it is.

Industry data, consistent with our years of experience performing home audits, show that your building envelope and duct system leak up to 40% of the air that pass through them. Imagine $40 of every $100 you spend to heat or cool your home is wasted by leaking into your attic, crawl spaces and outside.

SolarCity Energy Explorer can recommend and implement energy upgrades and repairs to further improve your home's efficiency. It's included with every solar power system.

1. Home Insulation
Properly insulating your home will not only help reduce your heating and cooling costs but also make your home quieter and more comfortable.

2. Window Replacement
Double pane, low emissivity (low-e) windows can help reduce outside noise, drafts, heating and cooling costs.

3. Solar Thermal
Solar thermal systems allow you to harness the power of the sun to both heat water and your home.

4. Air Sealing
Most homes have small cracks and holes where the air you paid to heat or cool leaks outside. Sealing your “building envelope” reduces drafts, saves money, and keeps must, mold and allergens out.

5. Solar Electric Panels
When you convert sunlight into electricity you reduce our collective dependence on fossil fuel. Solar can immediately lower your energy costs and protect yourself from rising electricity rates.

6. Energy Efficient Lighting
Lighting consumes about 10% of a household’s electricity use. Replacing incandescent bulbs with more efficient CFLs and LED lighting can reduce energy use in homes by 50-75%.

7. Duct Sealing
The average duct system leaks 30% or more! If your furnace frequently turns on and off or if you have some rooms that are too hot or too cold—these are signs that your ducts may be leaking. Properly sealing your ducts directs the air that you paid to heat or cool inside your home, making you more comfortable and saving you money.

8. Energy Star Appliances
Your washer, dryer and refrigerator probably accounts for almost 90% of your appliance energy bill. New Energy Star models can reduce the amount of energy use by half compared to models that are over 10 years old.

9. High Efficiency Water Heaters
Heating water can account for 15-25% of the energy consumed in your home. Reduce your monthly water heating bills by selecting a high efficiency or a tankless water heater
