Solar PV Analysis of Anna, United States
The location of Anna, Texas, is pretty good for generating energy using solar panels throughout the year. The amount of electricity that can be produced varies by season. In summer, you can expect to generate the most power with around 6.88 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar panels. Spring and autumn also have decent production rates with approximately 5.29 kWh/day in spring and 4.93 kWh/day in autumn per kW of installed solar.
Winter sees a drop in production to about 3.04 kWh/day per kW of installed solar due to shorter daylight hours and lower sun angles, but it's still enough to make having solar panels worthwhile.
So if you were thinking about when would be the best time to generate solar power at this location, summer would definitely be your top choice followed by spring and fall.
Now let's talk about how you should position your solar panels here for maximum efficiency all year round: You'd want them tilted at an angle facing southwards by about 30 degrees; this allows them to catch as much sunlight as possible over the course of a day throughout different seasons.
As far as local factors that might affect your ability to produce power from your panels go: Anna is located in Northern Texas which does experience some severe weather conditions like hail storms or tornadoes which could potentially damage your equipment or block sunlight from reaching the panels if not properly protected against such events.
To help ensure greater energy production despite these potential setbacks you'll want sturdy mounting systems that can withstand strong winds and protective measures like reinforced glass or covers that are resistant against hail damage for example.
Also keep in mind regular cleaning will help maintain optimal performance because dust accumulation on panel surfaces could limit their ability to absorb sunlight effectively - especially considering Texas' propensity towards dusty conditions during certain times of year.
In summary, while there are challenges associated with any location, Anna, Texas is a pretty good spot for solar energy production overall.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Anna
Seasonal solar PV output for Latitude: 33.3438, Longitude: -96.5635 (Anna, United States), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 30° South in Anna, United States
To maximize your solar PV system's energy output in Anna, United States (Lat/Long 33.3438, -96.5635) throughout the year, you should tilt your panels at an angle of 30° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Anna, United States
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Anna, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 17° South in Summer | 38° South in Autumn | 49° South in Winter | 27° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Anna, United States
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Anna, United States.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Anna, United States
Anna, United States is located in the state of Texas and the topography around this area is largely flat to gently rolling terrain. The region features plains and some small hill areas, with a mix of pastureland, agricultural fields, and suburban areas.
Considering solar PV installations, large-scale operations would be best suited for open and flat areas that receive ample sunlight throughout the year. In Texas, these conditions are often met in farmland or ranch land where there are fewer obstructions such as tall buildings or trees.
The exact suitability would depend on specific factors like local zoning laws and regulations related to renewable energy projects. However, generally speaking:
1) Areas south-east of Anna (near Westminster) seem to have larger tracts of unobstructed land which could be suitable.
2) Some parts north-west towards Van Alstyne might also be feasible given their open space.
It's important to note that besides geography/topography other factors like solar irradiance levels (how much sun an area gets), availability of grid infrastructure for power transmission/distribution & economic feasibility should also be considered while deciding locations for large scale solar PV installations.
For a precise assessment professional site surveys and consultations with renewable energy experts would be necessary.
United States solar PV Stats as a country
United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United States?
Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
