Annual Solar Production FAQs
How much energy does a 1 kWp solar system produce in a year?
Yearly production depends heavily on your local climate and latitude. In sunny regions, a 1 kWp system can generate between 1,300 and 1,600 kWh annually. In cloudier, northern climates, the same system typically produces between 800 and 1,100 kWh per year.
Do solar panels still work in the winter?
Yes, solar panels generate electricity from light, not heat—in fact, cold temperatures actually improve panel efficiency. However, overall winter production is lower because the days are shorter, the sun sits lower in the sky, and cloud cover is typically more frequent.
What is a good Specific Yield (kWh/kWp) for solar?
Specific Yield measures how efficiently your system turns its rated capacity into actual usable energy over a year. A yield of 1,000 kWh/kWp is considered a solid baseline. Anything over 1,200 is excellent, while a yield below 800 usually indicates heavy shading or a sub-optimal climate.
