Here’s a breakdown:
- Performance Degradation: Most panels lose about 0.5% to 1% efficiency per year. This means after 25 years, they may still operate at around 75–87.5% of their original capacity.
- Warranties: Most manufacturers offer performance warranties that guarantee panels will produce a certain percentage of their original output (e.g., 80%) after 20–25 years.
- Durability: Solar panels are designed to withstand harsh weather, including rain, snow, and hail. Proper installation and maintenance can extend their lifespan.
With advancements in technology, newer panels are becoming even more durable and efficient, so the lifespan may continue to increase.
The warranty periods for solar system components vary depending on the manufacturer and quality of the product. Here’s a general overview:
1. Solar Panels
- Product Warranty: Typically 10–25 years, covering manufacturing defects and physical issues.
- Performance Warranty: Usually 25–30 years, ensuring panels maintain a specific performance level (e.g., 80–90% of their initial output after 25 years).
2. Inverter
- Warranty Period: Generally 5–15 years, depending on the type and brand.
- String inverters: Often 5–12 years, extendable to 20 years with additional cost.
- Microinverters: Commonly 10–25 years, reflecting their longer lifespan.
3. Batteries
- Warranty Period: Usually 5–15 years, or a specific number of charge-discharge cycles (e.g., 6,000–10,000 cycles).
- Lithium-ion batteries often come with warranties of 10 years or 70–80% capacity retention.
- Lead-acid batteries typically have shorter warranties, around 3–5 years.
Yes but only if you have a battery attached to your system, if you do not have a battery then the system will shut down for the period of the power outage. Our Fronius inverters can have a PV point installed which becomes live when there’s a power cut. This is a back up solution if you want some limited power during a power cut ad you don’t have batteries. Its basically a dedicated power point which is only live during a power cut and when the sun is shining on the panels
A residential installation usually takes our installers 1 – 2 days, but we might need longer if your system’s bigger or more complicated. Once the installation is done, we then get an independent electrical inspector to sign off your system and make sure it meets regulations.
Any power not consumed which flows back to the grid you are refunded for each month. This helps a lot to off set your time usage.
DMAK account for everthing associated with the instal of the system. The only extra cost we can’t include is that of the import / export meter which is usually around $150 and added directly to your power bill.
You can view your progress and performance on the app or website of chosen solar Inverter provider.
This all depends on your usage and how much you decide to invest in solar, we generally like to see systems paying them selves off around the 6 year mark but can be sooner if your usage is high and the system is set up correctly.
You can get green loans through your bank 0-1% interest OR MTF finance can lend on your solar system
Dirty solar panels can lose 20% of their energy output, so whilst there’s no hard and fast rule when it comes to cleaning frequency, the general rule of thumb is at least twice a year to ensure they’re working as efficiently as possible.
Solar panels will still generate electricity on cloudy days or in foggy weather, just to a lower extent. Cloudy days will usually result in the panels producing 25% of their typical capacity, with the exact amount depending on how thick the clouds or fog are.
If you oversize your inverter you will be able to scale your system up by adding more panels. For example if you install a Fronius 5.0kw inverter coupled with 3kw worth of panels, you have the option of adding more panels (provided you have the roof space) to increase your system output when you are ready.
