FAQ Solar Panels & Cells

What is the life span of solar panels?

Under the energy crisis nowadays, solar energy become one of the most sustainable energy in the world. To convert the sunshine into real energy and electricity, we need to use some tools – That is solar panels. The photovoltaic panel is one of the most common used solar panel in the world. With the development of the technology, a photovoltaic (PV) solar panel usually have a life expectancy of 20-40 years. “20-40 years? Is it possible?” Some people would ask similar...

How many solar energy are we receiving from the sun every day?

Our largest source of energy - The SUN is providing 970 trillion kWh worth of free energy on us every day. Enough solar energy strikes the United States each day to supply its needs for one and a half years.Put it another way, the amount of solar energy the Earth receives every minute is greater than the amount of energy from fossil fuels the world uses in a year!

Do I Have to Maintain Solar Panels?

A periodic inspection to remove dirt, debris and check electrical connections is all that is needed. Keeping the panel clear of snow and debris will allow for better results.

Is shade a problem for solar panel?

Yes, shade can be a problem because there are a number of individual solar cells within a solar panel that need to be expose fully to sunlight. This is mainly because of the way the wiring of the solar panels are designed. So for example if there were ten individual solar cells and due to shading, one of the cells did not receive sunlight exposure, this will affect the power output of the nine other individual cells, even if the...

Which direction should I place my solar panel?

Direction and angles are the one of the most important factors in setting up a system. These issues can affect the performance and the efficiency of the whole system. Ususally we suggest people to place the panels facing south, that is the general direction. But tons of factors can vary the exact directions and angles, including latitude and climate in your location. Consult a solar specialist would be a good choice for you if you need help.

Do I need a back-up battery system when installing a solar energy system?

No, all solar energy systems are connected to your grid system. All of the electricity that you do not use goes into the grid system, but you never have to worry about running out of power because you have energy coming in from your solar energy system along with the electricity that comes from your power company.

Can the cost of producing solar panels be covered from the benefits they will bring?

It was inefficient to produce solar panels when PV technology was young years ago, producing solar panels cost around $40,000 per Watt. Modern date solar technology enables highly efficient solar panels. Impartial studies have done to show that the payback time for average solar systems to save enough to offset their production cost only takes three to four years. Putting into consideration that most solar panels have a life span longer than 25 years, it is very wrong to call...
