Sunsave’s solar offering differs from most other installers on our list in that it offers a long-term 20-year loan on your solar system, meaning there is no up-front cost. According to the company, customers may save up to one-third on their electricity bills from the very first month.
The interest rate is also very low, at 3.3 per cent per year, making it comparable to a mortgage rate.
Every Sunsave system includes a battery, helping users get the most use out of the power they generate, so long as everything is set up to maximise solar use.
Sunsave offers free replacements for parts such as batteries and inverters, which may come to the end of their working lives before solar panels do. The company provides a comprehensive guarantee: “Under the Sunsave Guarantee, whether in warranty or not, we’ll replace any equipment that isn’t working to a suitable level of performance – so the customer has peace of mind their system will be working to at least the projected levels for at least 20 years.”
The long-term loan structure makes Sunsave solar panels ideal for households with high energy use, ample roof space, and plans to stay in the property for years to come.
The length of the loan means you’ll probably also plan on staying in your home for a long time, although Sunsave says the loan can be transferred to a new owner; though, this could complicate resale. For instance, if you move house, will your buyer take on the monthly payment?
You’ll also want to make the best of any power you sell back to the grid, snagging the best deals for exporting.
Adding interest payments to the mix theoretically lengthens the time it takes to break even on the equipment.
One consideration is the total cost: with interest payments, you’ll likely pay more over time compared to an upfront purchase. For reference, other solar buyers typically break even within five to 13 years, depending on system size, usage, and future energy prices.
However, if you prefer predictable payments, minimal risk, and the promise of free electricity after 20 years, Sunsave solar offers a compelling alternative.
Pros:
- No upfront payment
- Fixed monthly price
- All components and maintenance covered for 20 years
- Claimed savings from day one
- Free electricity once loan ends
Cons:
- Higher overall cost due to interest
- Potential complications if you move house
