Are you planning to purchase solar panels, but you don’t need to power your entire house? Maybe you bought a jacuzzi or another new device and you want to use solar energy to power it? Then you might consider buying plug-in solar panels. These are ready-made packages that you install yourself. Connect the panels to a power outlet and you can start generating energy.
The advantages and disadvantages of plug-in solar panels
Plug-in solar panels’ main advantage is that they’re easy. There is no need for an installation company, which will save you a lot on the total price. There is no need for an inverter, no extra group in the meter cupboard and no complicated installation procedures. In addition, you can also easily take the solar panels with you when you are moving house. You can use an app on your phone or tablet to monitor your solar panel’s performance. This works particularly well if you are looking for a small installation to generate some of your electricity. A disadvantage is that there must always be a socket near the solar panel and that you cannot connect more than two panels to one socket. In addition, this is really only suitable for small installations, if you want to generate a proper amount of solar energy, then this might not be the best choice.
The big advantage of this plug-in system is that you don’t have to deal with installation costs. You only pay for the material. The price you pay for this can be found in the table below.
|Type of plug-in solar panel||Wp||Price|
|Single plug-in panel for flat roof||270||$430|
|Double plug-in panel for flat roof||2×270||$730|
|Single plug-in panel for wall mounting||270||$430|
|Double plug-in panel for wall mounting||2×270||$775|
Choices that affect price and profitability
When purchasing a plug-in solar panel system, you will also be faced with a number of choices that affect price and efficiency. There are also factors that are beyond your control that can determine how much you pay. Here you’ll find the choices with the biggest influence.
It’s easy to calculate how much energy you can generate with one such plug-in panel. For example, have you bought a new device and would you like to generate the extra energy it needs from solar energy? You can multiply the number of Watt Peak (Wp) by 0.85. The result is the annual efficiency of the solar panel. A 270 Wp panel will therefore be able to generate almost 230 kWh annually in a moderate climate. This allows you to determine how many plug-in panels you need.
The plug-in panels won’t give the efficiency indicated by the Wp value in every situation. They’ll have to be in a good place, on the flat roof or on the wall. For example, it’s best if they are at an angle of 35 degrees and facing south. They should also be placed in a place where the sun can shine on them undisturbed for most of the day. Also consider wind gusts and make sure that the plug-in panels are well anchored. The installation is therefore very important for the return on investment.
Maintenance of the panels
If you want to get the best performance from the panels, you’ll have to make sure that they are clean. Bird droppings, leaves, snow, scale and dust, it all affects the performance of the solar panels. You can easily clean them yourself with water and a mild detergent.
