Simply put, solar is the most abundant source of energy on Earth. About 173,000 terawatts of solar energy strike the Earth at any given time - more t…
Read MoreOur sun is a natural nuclear reactor. It releases tiny packets of energy called photons, which travel the 93 million miles from the sun to Earth in a…
Read MoreWeather conditions can impact the amount of electricity a solar system produces, but not exactly in the way you might think.
Perfect conditions …
Read MoreObviously, some provinces get more sun than others. So the real question is: if weather can affect solar energy production, are some states better ca…
Read MoreWhen photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, …
Read MorePhotovoltaic (PV) solar panels are made up of many solar cells. Solar cells are made of silicon, like semiconductors. They are constructed with a pos…
Read MorePV solar panels generate direct current (DC) electricity. With DC electricity, electrons flow in one direction around a circuit. This example shows a…
Read MoreA solar inverter takes the DC electricity from the solar array and uses that to create AC electricity. Inverters are like the brains of the system. A…
Read MoreHere's an example of how a home solar energy installation works. First, sunlight hits a solar panel on the roof. The panels convert the energy to DC …
Read MoreHow many solar panels does the average house need? How many solar panels do I need for a 3-bedroom house? How many solar panels do I need for a 2000 …
Read MoreTo determine your home’s average energy requirements, look at past utility bills. You can calculate how many solar panels you need by multiplying you…
Read MoreLook at your electricity bill for average usage. Look for “Kilowatt Hours (or kWh) Used” or something similar, and then note the length of time repre…
Read MoreHere’s where solar panel quality makes a difference. Not all solar panels are alike. Photovoltaic (PV) solar panels (most commonly used in residentia…
Read MoreIf you have a small or unusually shaped roof, solar panel size and numbers are important considerations. With a large usable roof area, perhaps you c…
Read MoreIf you’re planning on installing a rooftop solar system, understanding the weight of your solar panels is another key factor to consider. Knowing a s…
