We will also calculate how many kWh per year do solar panels generate and how much does that save you on electricity. Example: 300W solar panels in San Francisco, California, get an average of 5.4 peak sun hours per day. That means it will produce 0.3kW × 5.4h/day × 0.75 = 1.215 kWh per day. That’s about 444 kWh per year.
Research has shown that the carbon payback period for solar panels is on average 1-4 years.9 This means that over a solar panel’s lifetime – typically 30 years10 – it will generate zero-carbon and zero-pollution electricity for decades after any carbon emitted during its production has been paid back.
Whether they'll generate enough electricity for your home year-round will depend on: if your solar panel system works in a power cut. It may be more realistic to think about whether you can be self-sufficient for the brighter parts of the year, and then top up your energy use from the grid at other times.
From year to year there is variation in the generation for any particular month. There is less variation in the annual generation from year to year as weather patterns over the year average out. The annual generation of a solar PV system also varies with location in the country.
Like all electrical systems, solar panels degrade over time, which means they'll generate slightly less electricity as the years go by. The average solar panel system in the UK loses between 1% and 3% in its first year, then around 0.5% with each subsequent year.
At 25°C, solar photovoltaic cells can absorb sunlight efficiently and achieve their peak rated output. However, real-life conditions are far more dynamic anyway. The solar panel output fluctuates in real life conditions. It is because the intensity of sunlight and temperature of solar panels changes throughout the day.
