8.8kW Solar PV System Upfront Cost
This is an informative ℹ️ blog for individuals looking for an 8.8kW solar system with a battery storage 🔋. Especially if you are deciding between Alpha ESS and Sungrow battery. We will provide you with a real-time upfront cost of an 8.8kW PV solar system with both batteries, highlight the performance differences, and inform you about the available options for solar panels and inverters.
Key Findings
Why you need a solar battery storage?
We have already provided comprehensive details on why you should consider adding a solar battery to your solar system (e.g. 6.6kW, 8.8kW). One important factor we would like to highlight is how solar PV systems can help reduce your electricity bills 💸. How does it work?
Reduce your electricity bills
Any excess electricity generated by your solar PV system can be stored in a battery and utilized during the night. This is especially beneficial if your energy consumption tends to increase at night or if you frequently use energy during nighttime hours. By tapping into the stored energy, you can avoid relying on the grid 🗼 and save on electricity costs.
Alpha ESS or Sungrow battery storage
Both batteries are top-notch and best-selling in Victoria, Australia. However, there are a few factors that dominate Sungrow battery storage from Alpha ESS.
| Solar battery type | Built-in inverter | Flexibility and capacity | Performance | Maintenance |
| Sungrow Battery | No, you have to avail a separate solar inverter. We recommend Sungrow 8kW solar inverter for this particular solar PV system | Support 3-8 modules per unit, max. 4 units in parallel, 9–100kWh capacity range | Highly efficient | No maintenance required 😀 |
| Alpha ESS | Yes, 5kW built-in solar inverter. However, we recommend getting an additional 5kW inverter to ensure that the performance remains up to date. | 10.1 kWh Battery Modular, Expandable To 60.5kWh. Battery Modules Connection 1~6 in Parallel | Efficient | Maintenance required, if necessary |
How much is a 8.8kW solar system with sungrow battery and Alpha ESS?
| 8.8kW PV system with sungrow battery storage | 8.8kW PV system with Apha ESS battery storage | |
| Inverter | Sungrow 8kW solar inverter. This inverter can manage/run up to 16kW PV size. | Built-in 5kW solar inverter + 5kW GoodWe GW5000D-NS inverter. Together these solar inverters can manage/run up to 15kW PV size. |
| Solar panels | 20 × 440W Jinko Solar Tiger Neo | 20 × 440W Jinko Solar Tiger Neo |
| Battery backup/storage | 9.6kWh | 10.1kWh |
| Estimated cost | $3000 – $3600 single storey, single phase | $1500 – $1800 single storey, single phase |
Product warranty
As far as warranty is concerned:
- Alpha ESS – product retains at least eighty percent (80%) of its Usable Capacity
- for 120 months (10 years replacement warranty)
- Sungrow battery in Victoria – The performance warranty guarantees that the Battery maintains at least 60% of the initial Battery’s Capacity over the period 120 months (10 years replacement warranty)
- Jinko solar tiger neo panels – 25 year product warranty, 30 year linear power warranty, 0.40% annual degradation over 30 years
Please review one of the actual proposals we’ve prepared for a customer interested in an 8.8kW solar PV system below. First option covers Alpha ESS battery with built in solar invert + a GoodWe 5kW solar inverter. Second option covers Sungrow 8kW inverter and a Sungrow battery storage.
Why would you need an additional 5kW solar inverter with Alpha ESS battery storage?
While the Alpha ESS battery comes with a built-in 5kW solar inverter, we recommend installing another 5kW solar inverter to ensure optimal performance. This is particularly important if your solar PV size is large or you are planning to enhance the solar PV size in near future. By having this combination of inverters, you can effectively manage and handle your electricity load and current production without any compromise 😊.
Factors that can affect cost
Please note that the prices we shared above can vary depending on various factors, such as state or federal rebates, roof or property type. We have already explained all the major factors that can affect the cost of a solar PV system for your convenience and ease of understanding. Taking the time to go through them will help you make a more informed decision regarding your solar energy investment.
Conclusion
For an 8.8kW PV system with battery storage, Sungrow is recommended if budget allows, as it offers top-notch quality. However, if cost is a primary concern, Alpha ESS provides an economical solution. Consider your budget 💵 and priorities when choosing between the two options.
