Question 1

Do heated driveways use a lot of electricity?

Accepted Answer

•

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

Question 5

Can all homes support solar panel systems?

Accepted Answer

•

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.
