Congratulations! You’re about to make one of the best decisions for your home or business. Solar is a proven way to reduce your electricity bills and drastically decrease your environmental impact. Before you sign a contract with the first solar installer you meet, it’s necessary to equip yourself with the right knowledge. Here, we provide you with key questions to ensure you get the most out of your solar system and get your money’s worth.
Company stability
- Can you provide information about your company’s financial stability? A financially secure installer is more likely to be around, in the long run, to honour warranties and provide future support. Research the company’s experience and reputation online, and inquire about their financial standing.
- Do you install Tier 1 solar panels? Tier 1 manufacturers have established companies with a proven track record of producing high-quality solar panels. While not only the factor, using Tier 1 panels can contribute to a more reliable and efficient solar system.
Warranty
- What warranties are offered on the panels, inverter, and workmanship? Solar systems typically come with multiple warranties. These may cover the solar panels themselves, the inverter that converts DC power to AC power, and the labour involved in installation. Understanding the specifics of each warranty is essential.
- How long do these warranties last, and what do they cover? Warranty lengths can vary depending on the manufacturer and component. It’s important to know the duration of coverage for each part of the system and what issues the warranty addresses (e.g., manufacturing defects, material failure).
Off-grid
- Can the design be adapted for future off-grid capability? If you see yourself going off-grid in the future, this is a question worth asking. Off-grid capability of solar systems involves pre-installing upgrades like a larger switchboard, running conduit for future wiring, or strategically placing equipment for easier access during expansion. Planning for potential future off-grid needs can avoid costly rework down the line and maximise the long-term value of your solar investment.
Location
- Where will the solar system be placed: Discuss your preferences for panel placement, considering factors like roof space, potential shade, and visual appeal. Some installers provide software simulations to visualise the panel layout on your roof. You should also query the location of the inverter. Many inverters can be installed indoors or outdoors. The location may impact its warranty and may also require additional conduit.
- Can I customise the location based on aesthetics: While maximising sun exposure is important, you may have preferences regarding panel visibility from the ground. A good installer will work with you to find a balance between efficiency and aesthetics.
Shading
- Is shading going to be a potential issue for my system? Shading from trees, buildings, or even your own chimney or air conditioning unit can significantly reduce your solar panel’s electricity production. A qualified installer will conduct a thorough shade analysis to identify any potential obstructions and assess their impact on your system’s output.
- What are your shade analysis methods? Ask about the methods your installer uses for shade analysis. Some may use on-site measurements, while others might employ sophisticated software simulations.
- What are your mitigation strategies? If shading is a concern, discuss potential mitigation strategies with your installer. This could involve adjusting panel placement, trimming trees, or using special mounting systems to optimise sun exposure.
System performance and protection
- Does your production guarantee cover situations where the system underperforms? Some solar installers will stand behind their work and offer a production guarantee. This guarantee must outline what happens if the system fails to generate the expected amount of power.
- How will the system be protected from animal or rodent damage? Animals like birds and rodents can sometimes chew on wires or damage solar panels. Ask your installer about the methods they use to deter such critters and protect your system.
Monitoring
- Is consumption monitoring included in the system? Consumption monitoring allows you to track your energy use in real time. This data can help you identify areas for potential savings and optimise your overall energy consumption.
- Do you have additional system monitoring features? Some systems offer real-time monitoring that can alert you to potential issues like performance dips or equipment malfunctions. This allows for early intervention and helps maintain optimal system health.
Permits, damage, liability, and insurance
- Will your company handle obtaining all necessary permits for the installation? The process of getting permits can get complicated. Letting your installer take care of this ensures a smooth and compliant installation. This is especially important for suburbs with older homes.
- Who is liable for any damage caused during installation? Make sure the installer has a clear policy on who is responsible for any accidental damage during the installation process. Find out how many spare tiles (if your roof is made from such material) will be required.
- Can you provide proof of liability and insurance? Installer insurance protects you in case of unforeseen accidents or injuries during the installation. Request and verify this information for your peace of mind.
Battery options
- What battery storage options do you have with your current system? Explore the battery storage options compatible with the proposed solar system. Different battery capacities cater to varying energy needs.
- Does or will my system generate enough energy to store excess to use at night? Evaluate whether your proposed system design can produce enough surplus energy during the day to power your home at night with battery storage.
- What is the expected impact on my bill that adding battery storage will have? Ask for an estimated breakdown of how much you can expect to save with nighttime and cloudy-day power availability.
- What brands and models of batteries do you have available? Consider factors like warranty reputation and performance specifications.
Solar power is a rapidly growing trend in Australia and with good reason! Equipping yourself with the right knowledge before signing a contract is crucial to ensure you maximise the benefits and value of your solar investment. By asking these questions and getting clear answers, you’ll be well on your way to harnessing the power of the sun and saving money on your electricity bills for years to come.
