Let’s take some examples and use the solar panel angle calculator for some calculations.
Suppose we want to invest in a mini-solar power plant in two places in the USA. The first is Boston, Massachusetts, crushing Albuquerque, New Mexico. Then we will perform a small analysis and comparison of the results. Let’s briefly look at the characteristics of these two cities in different very different location in the USA:
our candidates
City to city - 2 exampes
Boston - Massachusetts
Boston – Massachusetts capital of New England. Boston has a humid subtropical climate characterized by hot and humid summers and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between 25° and 40°, and are located poleward of adjacent tropical climates. In some climate classifications, it is also known as a “warm temperate climate.” Winters are often cold and stormy with sporadic periods of significant snowfall, while summers are typically warm and humid. Depending on the direction of the wind and the position of the jet stream, spring and fall are typically chilly.
Albuquerque -New Mexico
Albuquerque, which is situated in north-central New Mexico, serves as Bernalillo’s county seat. County The elevation of Albuquerque is among the highest of any significant American metropolis. The climate in Albuquerque is often dry and sunny, with 3415 sunlight hours on average per year. Averaging 278 days of brilliant sunshine each year, the area is characterized by intervals of variable mid- and high-level cloudiness that temper the sun, mainly in the cooler months. Rarely can prolonged cloudiness linger for more than two or three days.

Basic instructions for calculation
Calculation flow for further analysis:
We will adopt the same configuration of solar panels with fixed panels at the ideal angle of inclination for the latitude that we will calculate by the formula Angle = Latitude * 0.9.
Let the number of panels be 10 x 10 = 100. The solar panel in both cases is the same. So all the parameters are the same except for the tilt angle of the panel, which we will adjust as ideally as possible according to city area.
The SPAC application uses the climate characteristics of the region for calculation, and the most important is cloudiness. First, we launch the SPAC application for North America. Then we find the city of Boston in the combo box and fill in the data: tilt of the panel 41 degrees, orientation to the south 0 degrees, option Grounded (the Sokar power plant is on the ground, not on the roof) We chose a network of 10×10 panel type: Q Cell Q Peak Duo with a power of 458 Wp. It is same for Albuquerque, except that the tilt angle of the panel is smaller and amounts to The entered parameters can be seen in the pictures.

After the calculation, we will skip all theoretical tables and stick to “Real data estimation.” There we see the average electricity gains for the day of the month. Table representation >

Distance beetwen panels
https://solarpanelanglecalculator.com/shadow-on-the-solar-panel/To avoid shadow, we need proper distance beetwen panels. More about shadow problems you can read here >>>>
Albuquerque has almost 1m smaller distance beetwen panels, which is good. It cause smaller area for power plant.
Area
The next step is choosing an inverter and entering the electricity price. The price is important for the calculation of profit from investments. We will take the price of 0.1 USD per kWh for our cases. And finally, we get the final report.

Expected annual prediction and profit Total investments in USD. We can conclude that due to the geographical position and better climatic factors, it is much more favorable to invest in Albuquerque than in Boston. With a similar installation of panels and inverters, even 27.6% more electricity will be obtained.
