Solar panels typically have a lifespan of 25 to 30 years, during which they continue to generate electricity and savings.
How do solar panels reduce your electricity bill?
Solar can reduce your electricity bill through: You can save the most money by self-consuming, or using, the electricity generated by your solar system. You can think of a solar panel as being a bit like a tap with water flowing out of it. The power output (measured in watts or kilowatts) is how fast electricity flows out of the panel.
Do solar panels make a difference in the payback period?
The electricity your home consumes plays a significant role in the payback period. Homes with higher energy consumption tend to benefit more from solar panels, which can generate substantial savings on monthly electricity bills. Review your past electricity bills or consult a solar energy auditor to estimate your energy consumption.
Can you use solar energy to power your home or business?
When you use solar generation to power your home or business appliances, you need to buy less electricity from your electricity retailer. This is called solar self-consumption.
