Many questions about the best tilt angle for solar panels can be answered in my main solar page. But some situations are more complex. If your panel orientation is only a few degrees from the optimum, it isn’t going to make a enough difference to worry about. But if you need an analysis for your particular situation, I can help. You may need help if:
Let me know the details, including your latitude, the orientation of your panels, and your specific question. My rates are:
|Calculate the optimum tilt angle for the year||$30 USD|
|Calculate the optimum tilt angles for the four seasons||$50 USD|
I accept PayPal.
Disclaimers: I do not forecast weather. An estimate of power generated is only an estimate, actual power production is affected by many factors. I don’t recommend any particular brand of solar panel. My analysis only determines the optimum angle under ideal conditions.
I have a B.S. and M.S. from M.I.T., and have been consulting on solar projects since 2001. I have consulted on projects for single homes and for megawatt systems. I have consulted on projects located in North America, Central America, Europe, Asia, Africa, Australia, and the South Pacific, and at latitudes ranging from within a few kilometers of the equator up to 62°. My own home has an off-grid photovoltaic power system.
