Perfect Angle For Solar Panels Idaho

If your residential pv system has surplus production during one month you get a credit on your next electric bill where you get back the full retail price of every kilowatt hour exported.

Perfect angle for solar panels idaho. If your latitude is outside this range see other situationsbelow. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180. There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels. For the best results solar panels should be oriented towards the south.

While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. The more exact way to count out the best tilt angle is done as follows. If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees. For a latitude up to 25 take your latitude and multiply it by 0 87 for a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees for a latitude over 50 the most ideal angle will end up being approximately 45 degrees.

We must therefore know on which side there is higher solar radiation for the whole day in order to have the maximum possible power production. This is because the sun is always in the southern half of the sky in the northern hemisphere. Solar panels should always face true south in the northern hemisphere north in the southern hemisphere tilted from the hoizontal at a degree equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.

This table gives some examples. On average the state of idaho receives 4 92 daily peak sun hours. A state level tax credit in addition to the 30 federal tax credit. The best tilt angle for winter is the latitude times 0 875 plus 19 2 degrees.

An additional 3 5 though can be gained by evaluating this more carefully. Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter. A fixed tilt solar panel does not change angles to adjust with the sun so looking at the average peak sun hours using a fixed tilt panel can set a good baseline for calculations. The two strongest points in favor of solar power in idaho are.

Both of these angles require latitude degrees. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.

The summer optimum tilt angle on the other hand will be 34 15 19. You will get around 37 of the pv system cost back as tax deductions. Orientation of the panels.
