Mini solar power plant: for an apartment, cottage or camping

Mini-solar power plant: what is it and where will it be useful?

What do you imagine when you hear about a solar power plant? A huge space filled with photovoltaic panels? A home format where the roof of a private house is covered with modules? Yes, all of this is true! However, did you know that a solar power plant can fit in the trunk of your car or in a rather limited space outside? And there are also mini-solar stations that can even be carried in a travel backpack? In this article, we’ll tell you what a mini-solar power plant is, what benefits it provides, and where it will be useful.

What is a solar mini-power plant?

In essence, a mini-solar power plant is the same as a solar power plant, which is an autonomous, renewable and environmentally friendly source of energy.

It consists of the following components:

• small-sized monocrystalline photovoltaic panel – due to the highest efficiency of all types of solar panels, it has high efficiency and efficiency of up to 25% even with small dimensions.
• A rechargeable battery built into the station body. It stores the generated electricity that you can use to power numerous devices.
• An inverter, which is also built into the body of the solar mini-power plant. It converts the direct current generated by the photovoltaic panels into alternating current, which we actually use to power electrical equipment.
• A controller that ensures the stable operation of the entire station.
• Solar cables for connecting the panels to the station.

As a result, we get the same autonomous SPP, but in a compact format. In terms of power, a 115w 220v mini solar power plant can provide a backup power source for lighting fixtures, small appliances, computer and mobile gadgets, etc. There are also less powerful options, for example, a 60w 220v mini solar power plant, which is enough for basic needs in a hike or camping, such as regular charging of smartphones, flashlights, or connecting a not very powerful electric stove.

Weighing the advantages and disadvantages of a mini-solar power plant

Of course, mini-solar power plants are not a complete replacement for a grid-connected or stand-alone solar power plant with a capacity of 1-30 kW. However, they definitely have their advantages.

• Compact dimensions: such a station will find a place in the trunk of your car or in a small apartment.
• Lightweight: It’s a camping version, so you can transport it even by yourself.
• Convenience for travel: it can be taken on a hike or on the road, and can be a good source of energy for truckers or buses.
• Enough power for your immediate needs: when traveling, during blackouts, camping or at a cottage where there is no centralized power supply, a mini-solar station will help you stay connected, keep the lights on and even cook with electrical appliances.

But, in the end, a mini solar power plant is much more affordable than a grid-connected solar power plant, and even more so than an autonomous solar power plant.

As for the disadvantages, they include the following:

• Still, it is quite a high price.
• Low capacity compared to stationary SPPs.
• The need for additional protection of vulnerable parts of the solar plant during transportation.

Where can a mini solar power plant be used?

Now let’s look at where mini-SPPs should be used. First of all, it is a tourist accessory that is indispensable for road trips, hiking, and traveling in your own motorhome or yacht. It is also well suited for setting up seasonal campsites and outdoor recreation camps. In recent years, a mini-solar power plant for an apartment has also become a good option, as it is much more efficient than power banks, and it produces energy for free, unlike power plants that simply charge from the general grid. So, for blackouts, grid outages, which DTEK regularly imposes, or emergency shutdowns, it will be the most efficient and profitable backup power source in the long run.

It is also worth considering buying a mini-solar power plant for a summer cottage or country house if the electricity supply in the area is unstable or the house is not connected to the centralized power grid at all, as is the case in remote garden communities.

And now there is another aspect of solar mini-power plants. This is, of course, the needs of the army. No, it is unlikely to be effective on the front line because of the vulnerability of the components, but in temporary deployment centers or training grounds it can be very useful.

What to look for when you want to buy a mini-solar power plant

Currently, the Ukrainian market offers many modifications of such an autonomous source of energy generation. So, in order not to lose money, it is better to pay attention to the following parameters:

• Station power: the higher the power, the more gadgets or devices you can charge or power.
• Battery capacity, as it directly determines the operating time of your station under load.
• Type and efficiency of the PV module. Monocrystalline PV panels are the most efficient, but they are also the most expensive.
• The dimensions and weight are particularly important if you plan to use the station on the road or in a camping trip.
• The manufacturer and its warranties. It is better to choose products from well-known and reliable manufacturers, although they may be significantly more expensive than Chinese products from know-how manufacturers.

In general, a mini-solar power plant is not a global solution to energy supply problems, but a backup source that can provide you with minimal comfort from the use of alternative energy. Therefore, if you need a more powerful solution for home use, it is better to consider on-grid or hybrid PV systems. At iSolar, they will definitely cost you not much more than the most powerful mini-solar station, but they will bring much more benefits and efficiency.
