Solar Power in Tampa Bay

Solar Generation

A solar installation in Tampa Bay area, which is installed with good access to the sun, can get around 4.3 kWh of solar energy per kW installed on average per day throughout the year. Fortunately, as we all know about sunny Tampa, you can expect sun throughout the year. With a solar system that is installed for maximum performance throughout the entire year, there is not a lot of difference in production from summer and winter.

Average daily solar output*

This data assumes an optimal 28° pitch for Tampa Bay area, see next section for details on optimal panel angles.

Interestingly, like many tropical areas, Tampa Bay receives the most solar irradiance in spring, rather than summer. Come summer, regular storms mean more cloud cover and erratic sunshine. The best month for solar production is April, which should produce over 5 kWh on average with a well installed system.

Per kW installed

Full year average: 4.3 kWh

Summer (Jul): 4.36 kWh

Winter (Jan): 3.78 kWh

For a 12kW system

Full year average: 51.6 kWh

Summer (Jul): 52.32 kWh

Winter (Jan): 45.36 kWh

Estimated Daily Solar Production | Per kW installed

Optimal panel angle

The optimal panel angle in Tampa for year round solar production is 28° from the horizontal, and facing due south (azimuth 180°). This allows for the most total production throughout the year. However, depending on when you use the most electricity, you may want to consider optimizing your installation for different times in the year.

Most people in Tampa would be better off with a lower panel angle than a higher one, due to higher electricity usage in summer, and also they will be more secure in super high wind conditions. Bear in mind that roofs typically have a pitch of between 15 - 30°, and it usually takes sense if you are installing on a house, to simply lie the panels flat on the roof without changing the angle. This is due to cost, fixing and aesthetics. Installs look nicer when they are flat against the roof, they are more secure, and there is extra costs involved in changing the angle, both in parts and labour.

Here is a guide to the different production you will get throughout the year with different panel angles:

Winter optimized production | 43° pitch*

Per kW installed

Full year average: 4.18 kWh

Summer (Jul): 3.86 kWh

Winter (Jan): 4.00 kWh

Summer optimized production | 13° pitch*

Per kW installed

Full year average: 4.27 kWh

Summer (Jul): 4.68 kWh

Winter (Jan): 3.34 kWh

* This data is purely theoretical, based on solar irradiance and a 12% derating, every installation is different and should expect different outputs. See below for some example installations.

Example solar energy Installs

The State College of Florida Venice, have an 11.8kW system which is installed due south (180° azimuth) at a 20° pitch. This is close to the perfect direction and pitch for an install, and is a great example of the solar production that can be achieved in Florida. This installation uses Enphase micro inverters, and we can see the actual output of this system using the Enphase Enlighten software, as it is a publicly accessible system.

It is interesting to note that whilst the system produces more energy throughout the day on a sunny day in July, the energy output peak is actually a little higher in January, even though this system is not optimized for winter output. This is due to the fact that if sunlight is equal, solar panels perform better in cooler conditions.

The graph shows the energy output in 15 min intervals.

Summer solar production - July

11.8kW system facing south, with a 20° panel angle - produces 58kWh on a sunny day in July (4.9kWh per kW installed)

Winter solar production - January

11.8kW system facing south, with a 20° panel angle - produces 52kWh on a sunny day in January (4.4kWh per kW installed)
