Battery storage options
Decide whether or not you want to add a solar battery to your system. There are now solar storage options available to consumers, including Tesla’s new Powerwall battery. They don’t come cheap but they can have a positive impact on your solar savings depending on your electricity usage patterns. As a general guide, the more power you use at night the more likely it is that a solar battery is going to be advantageous.

Estimate how many daylight hours your rooftop solar panels may be subject to shading or obstruction by external objects. Your panels will still likely produce energy during times of shading, unless they are fully obstructed, in what is termed ‘hard shading’. If there is still some exposure to sunlight, for example, overhanging branches, it is estimated solar generation capacity will decrease by 50% during these periods. For accuracy, shading is measured in half-hour increments. If your rooftop is fully obstructed during times of shading, double the amount of hours you select for shading.
It’s possible to finance the purchase of your solar panels and pay nothing upfront. You can add the purchase cost to your home mortgage or take out a specific solar loan. Your choice of financing options will be factored into your solar calculation.
