“Cool” roofs are lighter in color than traditional black asphalt or dark wood shingles and save energy by reflecting light and heat away rather than absorbing them. This is known as “the albedo effect,” and many studies have documented significant energy savings from simply lightening the color of a roof.

When the nucleus of a radioisotope undergoes fission or fusion in a nuclear reaction, it loses a tiny amount of mass. What happens to the lost mass? It isn’t really lost at all. It is converted to energy.

Asphalt is the most common type of shingle used on housing and is also the best roof for solar panels. These shingles are made from a fiberglass or cellulose type of mat that is very flexible and durable, making it the perfect material for solar panels.

Most solar panels weigh about 40 pounds That means, for pitched roofs, solar panels add about 2.8 pounds per square foot. For flat roofs, they add about five pounds per square foot.

Can a house run on solar power alone? It is possible to run a house on solar power alone. However, going completely off-grid requires a considerable financial and time investment. The higher your energy requirements, the more solar panels you’ll need.

Off Grid 5kW Solar System

A 5kW solar system can cover 40 to 90% of your electricity usage, lowering your bills by up to 90%! Refer to your electric utility bill to find your actual monthly kWh usage to determine how much power this 5kW solar system can generate. *Average American household electric consumption is 920 kWh per month.

The answer is YES. Generally, there are two types of solar system – off-grid and on-grid solar systems. Also, install more kW of solar panels if usage of AC is high. ACs can run on both of these systems.
