Frequently asked questions about solar power systems
1. What is the warranty on the system?
Every solar PV panel we sell is covered by a 25 year power output warranty. Additionally, manufacturing warranties can cover your entire solar power system for up to 10 years. As we stock a variety of brands, warranty specifications will differ from product to product.
2. What does my warranty cover?
Generally, most mechanical defects will be covered during the warranty period as long as they are deemed a manufacturing fault. Most suppliers also guarantee 80% power production for the first 25 years of your solar power system’s life. It is important to understand that warranty terms and conditions vary supplier to supplier.
3. Are GGG’s PV panels and inverters tested to Australian quality standards?
In a market flooded with substandard and potentially dangerous imports, Australians must be vigilant when choosing solar energy products. GGG only stocks solar PV panels and inverters accredited by the Clean Energy Council – Australia’s peak body for clean energy.
4. Will my solar panels withstand extreme weather conditions?
Solar panels are designed to withstand harsh weather climates, from blistering heat to freezing cold. Our solar panels are also put through extreme hail tests. They have an allowable hail load of 7.53 grams travelling at 23 m per second. Our panels are protected by a 3.2 mm low-iron tempered glass coating.
5. Will my solar power system work at night?
At night, there is not enough sunlight to sustain operation. As a result, it is completely normal for your solar power system to turn off when the sun is down and then resume work in the morning.
6. Will i still have power if the neighborhood blacksout?
In the event of a blackout, your solar power system will switch off and remain inactive until power returns. This is a mandatory safety feature of your solar power system. It is designed to protect those who may be working on the blacked-out grid system.
You must ensure that all of the switches on your solar power system are set to ‘on’when the grid returns to normal. If your switches are turned off, you will not generate solar electricity.
7. Why is there an error/fault description displaying on my system?
Disturbance in the grid, caused by voltage spikes, can make your inverter manually shut down in order to protect your property. This can cause an error notice to display.
It is recommended that you monitor your system overnight, as generally it will correct itself. You may also try restarting your system manually following our easy guide. If you’re not comfortable doing this, or your system continues to display an error message, please report the problem here by clicking here.
8. Why is my solar power system not working efficiently?
If you’ve noticed a substantial change in your energy savings, there are a number of things that you should check before worrying about a fault with your solar power system.
- Check how many kilowatts (kW) you’ve used in the past, compared with now, using previous and current bills. The power generated by your solar PV panels and inverter won’t grow with your daily/average consumption. Put simply, if you’ve been using more power than normal, you will pay more when your electricity bill arrives.
- While you’ve got your electricity bills out, check the rate at which your utility is charging you for power. You may be paying more per quarter not because your solar system is working poorly, but because of additional costs issued by your supplier.
- Take a stroll around your property during the day and observe your solar PV panels. Check that neighbouring buildings, trees or other structures aren’t blocking sunlight from reaching the panels. Though your installer would have ensured an non-obstructed view of the sun at the time of installation, new factors may have emerged that are obstructing your panels from working properly.
9. How do I check my solar system’s performance and kW generation?
Please refer to this user manual.
10. Do we need to clean the panels?
Not if they on a pitched roof. The rain will clean the panels. If they are covered in bird poo or leaf matter, then they will need to be cleaned.
11. Does shade affect my solar power system?
Yes, however GGG panels use a multiple diode bypass system, meaning shade obstructions have a lesser effect on our panels.
12. Does the power i generate from my solar power system get used in my property or sent to the grid first?
The electricity from the solar power system will get used in your property first. Only the excess gets exported to the grid.
