F.A.Q.
SOLAR POWER
Q: What are the benefits of Solar Power?
A: It is quiet, clean and reduces electricity bills
It avoids the impacts of fossil fuel power stations such as greenhouse gas emissions and local air pollution, It will add value to you house, A solar system is silent, It is a renewable energy source
Q: How does Solar Power work?
A: Solar modules are mounted on the roof or grounds of your property converting sunlight into DC power. This power is sent to a device called an inverter (or power converter) which converts the DC Power from the solar modules to AC power identical to that being sent to you from the utility grid. Power then travels from the inverter to your electrical distribution panel (your meter or fuse box). The power from the electrical panel will be distributed to any electrical loads in your home. When excess power is produced by the solar, the power will flow into the grid through your electric meter. This will effectively gain you a credit with the utility company. The utility grid automatically provides electricity when needed – at night and during the day when your demand exceeds your solar production.
Q: Do you need batteries?
A: Batteries are not required for a grid system, but are necessary with a stand-alone system.
Q: Are the batteries reliable and how long will they last?
A: Yes. Batteries are generally very reliable and will last 5-7 years provided you look after them properly (the same way you do with your car) e.g. regularly check charge levels, top up with distilled water etc. Ask your installer for care advice, or they may offer you a maintenance plan.
Q: How much greenhouse gas emissions are reduced by Solar Energy?
A: A standard home produces on average 4,500kg of greenhouse gases each year. By installing a Solar System your home’s gas emissions can be reduced to an average of 2,500kg.
Q: How does a Solar System save our precious water?
A: Each kWh (kilowatt hour) of electricity produced by coal fired electricity uses 2.5 litres of water. By installing a 1Kw system you will be saving the environment around 3,750 litres of water every year.
Q: Will my Solar Panels survive a hailstorm?
A: Yes, Solar panels are made of tough laminated glass and are generally indestructible. They are also sloped so hail slides off.
Q: What will happen to the Grid System in a blackout?
A: By law, any solar grid system without generator backup must shut down until utility power returns in order to assure a safe working environment for utility line workers. The grid connect inverter will automatically shut itself off within a few milliseconds of a blackout, to avoid the potential of a dangerous “brown-out” in your home and to prevent back feeding the grid. You will need a battery back-up system if you want to maintain power during a blackout.
Q: How much will it cost?
A: The cost of Solar Electricity can vary significantly depending on the amount of power required. A home with a $50 per month electric bill will require a different system than a home with a $500 per month electric bill. For this reason, residential systems range in cost from $10k-100k.
Q: Is the Solar Power System an Investment?
A: Many homeowners finance their systems with funds from a home mortgage or home equity line of credit. Loan payments are frequently similar to or less than what a homeowner would pay the utility for power. Plus, the homeowner now owns a solar electric system that adds value to their property and protects them from future utility rate increases.
Q: Do I have to insure my Solar System?
A: Yes, you should insure your solar system, check with your home & contents insurance consultant.
