Solar FAQ’S

FREQUENTLY ASKED QUESTIONS

WHAT IS SOLAR POWER?

Solar power is the resultant conversion of sunlight into electric current via the use of solar photovoltaic (PV) panels. Additionally, it can be heat energy that generated from solar thermal systems which concentrate sunlight into receivers to heat water.

What is solar electricity?
Photovoltaic (PV) systems convert sunlight into electricity that can be used to power your home, office or industrial facility. Today’s solar electric technology can be harnessed to either supplement power supplied by your utility company or to take you completely off-grid from the utility company. Off-grid systems use battery back-up systems to store power. Grand Group Solar design systems that best fits our customer’s needs.

What is a solar panel?
Solar water heating and solar electric (photovoltaic) systems receive solar energy in rectangular-shaped panels“ also known as collectors. These solar collector panels are mounted on a building’s roof or ground-mounted in special situations. In solar water heating panels, water is heated by sun energy as it circulates through. Solar electric panels contain the materials that convert sunlight directly into electricity. Solar panels are engineered to operate in very high winds and withstand environmental damages.

Can solar energy lower my electric bill?
Yes, Solar panels are used to convert the suns energy into electricity that can be used by your home or business. The panels are connected to the electrical system generally using a bi-directional metering system. This allows your facility to utilize the electricity when it’s being produced by the sun to offset your usage from the power company.

Can solar energy reduce reliance on fossil fuels and foreign oil?
Because 85% of all Australian power comes from burning fossils, much of which comes from volatile priced foreign oil, anytime you lessen your dependency on utility power you’re helping our country reduce its reliance on energy from energy sources that are environmentally-unfriendly and financially unstable. Solar energy provides an alternative solution: less dependency on foreign oil.

How much does a residential solar system cost?
The cost of a solar system depends on the size of the system that is built. Systems can be built so they are scalable. It is important to know what size the solar panel system is, how much electricity will be produced, and the price per watt. Each solar system will produce different amounts depending on how good the design is, what shading could reduce the systems daily production, and where the solar panels are on the earth. Each geographical region and even location is going to receive different amounts of sun. After all of this is calculated, then you can make an educated decision on what size of solar panel system you need and want based on your energy demands and budget. Also, renewable incentives help offset the end and overall cost of a PV system.

How long do solar panels last?
Solar panels can last for a life time with 25 years manufacturer warranty.

How much maintenance is required?
Grand Group Solar solar energy systems require less maintenance and service if the owner strictly follows guidelines. In most cases, these guidelines require owners to not adjust, maintain or repair the systems themselves.

How do I get incentives from the government or utility company?
Programs from state, federal and utility companies have been changing frequently. You can view the most up-to-date information on the energy regulator Website.

Can I get a payment plan?
Grand Group Solar offers many financing options and will help you find the financing plan that best meets your needs.

What happens if there is no sun that day?
Lack of sunshine limits the solar energy potential of any solar energy system. However, Our Range of Solar Panels works with UV Rays during the daytime and can still produce some good amount electricity pending on the weather conditions.

Will a solar panel get destroyed during a storm?
Grand Group Australia engineers all its solar panel systems to meet the required wind load building codes established in all Australia.

I heard that the electric company has to pay me for surplus power. Is this true?
Each electric utility has its own programs for crediting customers who supply them with surplus energy (solar electric / PV power generated by a Grand Group Solar system that exceeds the home’s needs). Grand Group Australia solar energy specialists can help you understand those specific utility programs and how each affects the financial picture of your solar energy system.

How long does it take to install a solar energy system?
Most home systems can be installed by a Grand Group Australia crew in 1 or 2 days. Installation follows a thorough site survey and engineering review. Larger commercial or business installations can take longer depending on size, complexity and special mounting.

Does a solar panel need to be on my roof?
For most home installations, the roof is the optimum placement for solar panels. Unobstructed by trees or other shade-producing structures, facing toward the south and able to be securely attached. If the homeowner has adequate yard space and/or many panels to be installed, Grand Group Solar can review the option of ground mounting.

Do I have to angle solar panels at the sun all day long?
Solar panels are installed in a fixed arrangement. They typically don’t move to track the sun during its movement through the sky. Mounting the panels to face North at the proper angles enables them to capture and collect the maximum amount of solar energy during the day.

Can I adapt solar power systems for my business?
Due to higher incentives and rebates for businesses, solar makes just as much if not more sense for business owners. Add in the depreciation factor for a solar energy system capital expense, and the financial incentives become even more attractive
