There has been a considerable increase in the number of people shifting to solar, with more awareness and government support. If you are someone considering a shift to solar but are concerned about the limited availability of space, this one is for you. Small solar panels are the best way to start your journey towards self-sufficiency in energy. This blog gives you more details about mini solar panels, their use cases, and benefits.
What are small solar panels?
Small or mini solar panels are smaller versions of regular solar panels. They have been developed to meet the needs of people who have less space available. The number of PV cells that make up a solar panel is limited in small solar panels. This is mostly suitable for small devices, as it has a limited energy-generating capacity.
The wattage of small solar panels can be between 5 and 15 watts. They can be used to charge phones, LED lights, portable fans, and other devices, power small security cameras, small motor pumps, and more.
How do small solar panels work?
Small solar panels use the photovoltaic effect to convert sunlight into electricity. Solar panels are made up of (photovoltaic) PV modules that absorb sunlight. Once set up, they harness sunlight and convert it into direct current (DC).
While DC cannot power large appliances, it is still usable for powering small devices.
- Sunlight capture: There are many modules that make the solar panels, which capture sunlight during the day. The number of panels and their size determine the efficiency of output.
- Release of electrons: The PV cells are made up of semiconductor materials, which release electrons once they are exposed to sunlight.
- DC power: PV cells convert light into electricity. This is used to charge mobile phones, portable fans, chargers, etc. In the case of large solar panels, an inverter converts DC to AC, which is usable by large appliances.
- Output: Depending on the availability of sunlight, mini solar panels can produce an output ranging from 0.06 to 4 watts.
Small solar panels eliminate the need for inverters. Small devices directly use DC, hence the energy produced by mini solar panels is sufficient to charge them.
Why are small solar panels a smart choice?
Occupy less space
Small solar panels need less space than large ones and are suitable for small households and other urban locations where space is a constraint.
Affordable alternative
The small solar panel price is highly affordable and can be installed for less than INR 5,000. They are an easy alternative for people looking to shift to solar but are on a tight budget.
Easy to install
Mini solar panels are easy to install and can be carried to remote locations, too. This makes it a convenient option for many.
Protects the environment
Small solar panels offer the same environmental benefits as large ones. There are no carbon emissions and thus no pollution.
Portable
These solar panels are portable and can be carried even on your camping trips. They can be used to charge camping lights, Bluetooth speakers, and headlamps.
Given the benefits that make small solar panels a smart choice, they are useful only for small devices, as they can produce only limited power. They also need ample sunlight to function efficiently, similar to large panels.
Applications of small solar panels
Small solar panels are used to:
- Charge mobile phones
- Charge LED lights
- Power standalone streetlights
- Power small fans
- Useful for educational projects
- Power small water pumps using a DC motor
- Powering sensor equipment in remote areas with low grid connectivity
Choosing the sizing of small solar panels
The size of small solar panels depends on your purpose. Charging a small battery may be done in less than 10W, while a solar water pump may need 150W. Analyse your needs and ascertain the right type of sizing for your mini solar panel. Your small solar panel price also depends on the size of the panels. For instance, a 150W panel may cost around INR 7,000.
Things to watch out with small solar panels
There are certain limitations with small solar panels.
- They are usually low-wattage panels and cannot be used for powering appliances like air conditioners, refrigerators, etc.
- They produce limited energy, just enough to charge small DC appliances.
- There is not much regulation for small solar panels, and the manufacturing process without it can cause environmental damage.
- Battery storage has to be set up, as output is limited. But this can be expensive considering the size of small solar panels.
Conclusion
Small solar power panels are a wonderful option when you do not have extensive rooftop or ground space for solar systems but still would like to enjoy their benefits. You can set it up even on a small balcony and carry it along when you go camping. These mini solar panels work the same way as large ones, except for the limitation on the output. Connect with a reputed solar installation company to understand your needs and install a solar system accordingly.
