Solar makes the most financial sense when you can pay for your system up front. Not having to pay interest on a loan means you get the full benefit of your savings from day one.
If you need a solar electric system, but haven’t got the funds right now, financing can help.
If it’s going to take more than a few years to pay your system off with Finance, then we recommend that you try to add the cost to your mortgage. Most banks are very willing to provide a top up to your loan—especially as they will know that the solar is helping to repay your mortgage.
