The “tilt angle” or “elevation angle” describes the vertical angle of your solar panels. “Azimuth angle” is their horizontal facing in relation to the Equator. Solar panels should face directly into the sun to optimize their output.

Types of Solar Panel Mounting Solutions

1. Rooftop Mounting

This is the most common method for residential and commercial solar installations. Panels are typically mounted on racks that are securely attached to the roof structure. The type of mounting system can vary depending on the roof material (e.g., asphalt shingles, metal, tile). Ballasted systems are also an option for flat roofs, where weights hold the panels in place without penetrating the roof.

2. Ground Mounting

For properties with ample land, ground-mounted solar panels are an excellent choice. These systems involve a sturdy framework that holds the panels at an optimal angle, usually cemented into the ground. Ground mounts offer flexibility in orientation and tilt, allowing for maximum sun exposure throughout the day. They can also be installed as fixed-tilt systems or tracking systems that follow the sun's path.

3. Pole Mounting

Similar to ground mounts, pole-mounted systems elevate the panels on a single or multiple poles. This method is often used for smaller installations, such as those powering remote cabins, lighting, or surveillance cameras. Pole mounts can also be fixed or tracking, and they help keep panels above vegetation or potential obstructions.

4. Integrated Solar (Building-Integrated Photovoltaics - BIPV)

This is what you might be thinking of with "window antennas," though it's much more sophisticated! BIPV involves integrating solar cells directly into building materials, such as roof tiles, facade elements, or even windows. These systems serve a dual purpose: they generate electricity and act as part of the building's structure, often with a more aesthetic appeal as they blend seamlessly. While still developing, BIPV offers innovative ways to incorporate solar without visible racks or mounts.

5. Dynamic mounting systems

This system's automatically adjust the panels' position to follow the sun throughout the day. While more expensive and complex, they significantly increase energy output.

Single-Axis Trackers: These systems track the sun's movement along a single axis, typically from east to west. They can boost energy production by about 20-25% compared to a fixed system.
Dual-Axis Trackers: These track the sun on both a horizontal and vertical axis, allowing the panels to remain perpendicular to the sun's rays all day long and throughout the seasons. They offer the highest energy yield but come at a premium cost.

Solar Panel Mounts

Tired of the high cost of solar panel mounting systems? Try a clever hack using an old classic: slotted angle iron or metal angle post. These sturdy, versatile bars—once a staple in every hardware store—can be bolted together to create a durable and affordable frame for your panels. It's exactly what I used and still use for my own DIY solar setup, and it's a resourceful solution that saves a ton of cash while getting the job done.

Portable Solar resource

Simple and Sustainable

I use a portable solar panel to charge my devices on the go. It's like a power bank, but powered by the sun (though charging efficiency decreases significantly on cloudy or rainy days). This panel can also charge my actual power bank!

This is a simple way to be more sustainable while enjoying the outdoors. No need to hunt for outlets! I keep my smartphone, smartwatch, camera, fan, walkie-talkie, and other devices charged with my portable solar panel.

It's incredibly convenient and eliminates the worry of running out of power at the beach, on a mountain trek, or even during winter camping. I prefer to keep things simple and rely on renewable energy whenever possible.

my Wifi Router working by Solar ? anywhere? How?!

Simple, I chose a router with a 5v power supply. Yes, they exist and Tenda, Mercusys or Mi, for example, are some of the brands that has it, but exist more, and when you buy'it you can allways check, everything else is simple. Solar 5v panel por portable, powerbank and it's already working. Anywhere.

Example to spent at maxium a quantity of 50€ / $55 :

Tenda 4G05 | Mercusys MW325R | Xiaomi Mi Router 4C + Powerbank 10A + Solar charger 30W, 5V.

Have fun. I have, and next time when you buy something think solar and multiuse.

Smartwatch charged by Solar ? anywhere? How?!

Make sure the smartwatch charge is 5v, so if your smartwach have charging magnetic platform also have the cable. Look at the cable, is a USB entry. Consequently you can use like with the router in any portable Solar panel with the minium of 30W, 5V to dont take all day and ready to go or you can charge via powerbank who was previously charged by your portable solar panel. Easy and simple.

Have fun. I have, and next time when you buy something think solar and multiuse.

my portable usb fan charged by Solar ? anywhere? How?!

First make sure your portable fan have a Usb entry or you have one Usb battery pocket charger to charge your portable fan battery/ies. Consequently, as for both the router and the smartwatch, make sure you have a portable Solar panel with the minium of 30W, 5V to dont take all day and is ready to go. Don't forget that you can charge your powerbank using a portable solar panel if that's easier and more useful for you. Easy and simple.

Have fun. I have, and next time when you buy something think solar and multiuse.

Dont forget all other aplications and gadget's you can do and use or reuse ...

and again, It doesn't matter if there is no sun, the panel still produces energy, although not with "as much strength".

Remember, each small change in daily habits can have a big impact on the environment. Each time you/we choose a sustainable product, you/we contribute to the reduction of waste and to the conservation of natural resources, inspiring those arround us and creating a positive ripple effect.

Calculating the Optimal solar panel Angle

As a rule of thumb, solar panels should be more vertical during winter to gain most of the low winter sun, and more tilted during summer to maximize the output. Here two simple methods for calculating approximate solar panel angle according to your latitude.

Calculation method one

The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter, and subtracting 15 degrees from your latitude during summer. 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°.

Calculation method two

This is an improvement of the general method that gives better results. In this method, the optimum tilt angle for solar panels during winter is calculated by multiplying the latitude by 0.9 and then adding 29°. In the above case example of a latitude of 34°, the tilt angle will be (34 * 0.9) + 29 = 59.6°. This angle is 10° steeper than in the general method but very effective at tapping the midday sun which is the hottest in the short winter days. For summer, the tilt angle is calculated by multiplying the latitude by 0.9 and subtracting 23.5°. In the above case example, this angle would be (34 * 0.9) – 23.5 = 7.1°. For optimum tilt angles during spring and fall, 2.5° is subtracted from the latitude.

While these rules and calculations provide a basic understanding, they cannot fully replace the in-depth generation analysis conducted by specialized software using historical solarimetric data.

Several climatic factors, beyond just geometric considerations, significantly influence the optimal inclination angle for photovoltaic systems.

These principles also apply to portable solar panels. To maximize energy output, consider the inclination angle when positioning portable panels, although the practicality of adjusting the angle may be limited depending on the specific design.
