What Can I Power With A Solar Panel From My Balcony?

9th November 2021  

In the twenty-first century, using renewable energy is a modern trend. But how does it function in practice? Building such a system and testing it on their own is the best method to acquire an answer. Millions of tenants and apartment owners cannot benefit from solar since they lack a roof to install their balcony solar panels.

A conventional solar installation necessitates a substantial financial investment as well as a private roof. Installing solar panels on window ledges and balconies can help to overcome these challenges.

Should you install solar panels on balconies?

One can install solar panels on the balcony by themselves. It does not necessitate the assistance of solar firm installation. If you live in the northern hemisphere, your patio should face south.

Another benefit of such an installation is taking the solar PV with us when we leave the flat. Because you do not connect it to the apartments behind-the-meter electricity network, this solution is straightforward. It indicates that the solar panels for apartments are clean and precise to set up.

It would be helpful to have custom-made structural support in the balcony to firmly lock the panels in place as a protective measure. The proportion of panels gets determined by the balconies dimensions. The lower the price per watt, the larger the panel.

Larger panels, such as those rated at 320 or 360 watts, are available, but they are huge and heavy; 160 watts would be ideal. A meeting of this size is 150x70cm and weighs 12.5kg.

An inverter with a 22–60V input voltage would be optimal to connect two panels in series. You can also use micro inverters in place of traditional inverters.

Is it financially beneficial?

A balcony 360W system has a 25-year monetary repayment period. A typical setup would cost roughly $2000. The plan would generate 543 kWh of electricity per year on average.

You would have altered the entire computation if the panels were on the roof. Rooftop energy generation is far higher than that of balconies. A balcony system undoubtedly has its own set of restrictions.

Because of the modest balcony solar panels, the system's financial return is somewhat lengthy. Only that is possible due to the balconies space limits.

Cons to consider

Electricity generation will be reduced by 20-30% as a result of clouds. The appropriate tilt angle will last no more than 1–2 hours every day as the sun advances across the sky. It's hard to get an actual 100W output from a 100-watt panel.

The quantity of energy one can generate from a balcony is determined by their position and the amount of daylight their patio receives. After a day in the sun, a transportable solar panel might be able to replenish a smartphone.

Solar panel inverter

Solar PV generates electricity. That energy should be able to be stored as direct current. A battery must also be attached to the system that holds power. Any balcony solar panels array rated at 12 watts or more significant requires a solar panel charge controller.

Balcony solar panel batteries

Batteries are costly, and a balcony solar system also contains batteries. The long payback period is due to this as well. You may tilt solar panels according to the seasons to create more energy. When it comes to altering the tilt of panels fixed to a balcony, it's straightforward.

Because the quantity of panels is constrained and they have restricted exposure to sunlight, electricity production from the discussions on the balcony will be limited. There are a few suggestions for improving the electricity generation of solar panels for apartments.

Every hour, day, or month, you can make minor modifications. Changing the angle two or four times a year is sometimes all that is required.

Because the solar panels are so close together, you can clean them regularly. Solar panels positioned on the roof are difficult to clean. One percent of the energy generated gets lost due to dust and grime on the panels. The loss will be roughly 4-6 percent in dry, dusty, and high-traffic areas without thorough washing.

One can save energy by using a low voltage DC system. Solar panels generate DC, which is converted to AC by an inverter. For specific devices that function on DC internally, it gets converted back to AC.

Inverters convert DC to AC and then back to DC, resulting in significant power loss.

What can you power with balcony solar panels?

A solar panel coating on the balcony can run a 400-watt piece of equipment for 6–7 hours of light in a mid-size house with LED bulbs.

Depending on conditions and time of day, two 160 Watt solar PVs mounted on a balcony can produce 10–190 watts of power.

You may use it to consume a variety of home devices. If no current consumption is present, the surplus gets sent to the city power grid.

You can create a solar-powered charge controller for gadgets such as laptops, smartphones, wireless earphones, and a few 12V emergency lights on a balcony with solar panels for apartments and a battery.

After an entire day in direct sunlight (which we're reasonably confident you won't get on a balcony), a full-size panel (1.7m x 1m) will produce roughly 1 kWh per day. That's around 25 cents worth of energy on your residential tariff (on a good day).

With a solar panel spanning your balcony, you can run a 400-watt appliance for 6–7 hours. So figure out how much power you have on hand. This amount of energy will be adequate for a mid-sized house if you utilize LED lamps.

We recommend that you arrange for your system to use solar electricity to meet your home's energy needs whenever it is accessible. On the other hand, you can always use a traditional power source if you're having a bad day.

Bottom line

Choosing adequate energy PVs for a balcony solar system will help you get more electricity out of your system. Balcony solar panels power the entire house. A tiny balcony solar system will not be able to achieve the same results. Indeed, it can only assist in meeting some of a home's essential energy requirements.
