Get Something Easy to Install

This is a 5 watt solar panel, which means that it should be easy to install. Some manufacturers seem to forget this and make panels that are a nightmare to deal with. Avoid such manufacturers at all costs. The whole point of low wattage solar panels is that they don’t need a lot of work. Try to see what installation options are available. Chances are that your service provider can help you with that. A complicated installation process will lead to problems down the line. It depends on how many panels you want to put in, though.

Opt For Aluminum in The Frame

You don’t need anything heavy duty for a 5 watt solar panel. It’s lightweight and low maintenance. A simple aluminum frame would do the trick. It would keep your solar panel stable. As well as be reasonably durable. Aluminum does not rust as easily as steel or iron. Which means that you don’t have to worry about frequent oiling. This simplifies things quite a bit. You can make do with aluminum which is cheaper. This can save you money for other purposes. Solar setups can always use a bit more investment, after all. Saving money on the frame helps you out in this regard.

Use Alligator Clips to Keep It in Place

The lightweight nature of a 5 watt solar panel is usually a good thing. However, your battery charger would need to be kept stable. Strong winds can move it around. This might damage the panel. Even if it doesn’t sustain damage, a change in position can be harmful. It can reduce the amount of sunlight your panel would receive. You should use alligator clip with your solar module. This controls the movements of your 5 watt solar panel. Such clips can also add to overall stability. Eventually, this would lead to greater solar energy production.

Get a Good Battery

The best use for a 5 watt solar panel is as a battery trickle charger. You need a good solar battery for this to be possible. Try to get a battery maintainer as well. This will increase the longevity of the battery as well. A battery maintainer is also a good way to get maximum efficiency from the battery itself. If you leave your battery charging for long enough, a 5 watt pane can leave it ready for an entire night’s worth of usage.

Don’t Compromise on Durability

The small size of your 5 watt solar panel makes it essential that you prioritize durability. Otherwise it won’t last very long before getting damaged. Try to find a panel that uses tempered glass. This is a very durable material. It can withstand a lot of blunt force without adding too much weight to the whole system. It’s a pretty rare material in that respect. An added benefit is that it’s clear. Hence, it won’t block any sunlight from the panel. This leads to maximum efficiency on top of superior durability.

Avoid Extra Weight

Sometimes the add-ons for your 5 watt solar panel can add a lot of unnecessary weight. You might think that these add-ons are crucial for excellent performance. However, this is not exactly the case. Additional accessories can be useful. But they are not worth it if they increase the weight. This would decrease the usefulness of a small panel. The benefits they provide are not sufficient to counteract this huge negative aspect. Keep this in mind. It will help you spend less money on the panel setup as well. Everyone could do with saving a few bucks after all.


Does a 5 watt solar panel need a charge controller?

A 5 watt solar panel generally doesn’t need a charge controller. It works through trickle charging. Solar panels that operate like this don’t generate a high enough voltage. The purpose of a charge controller is to stabilize voltage. Truly unstable voltage can have variations that are too high for a 5 watt solar panel to produce. You can still get a charge controller just to be safe. It can be useful if you have multiple panels in your array. A single panel won’t benefit all that much from this sort of thing, though. So it might just turn out to be an unnecessary expense.

Will a 5 watt solar panel charge a 12 volt battery?

A 5 watt solar panel is usually used as a battery trickle charger. This means that it will charge your solar battery but slowly. Batteries don’t have any wattage requirements to be charged. Even 5 watts is enough to keep the charging rate consistent. If you use a 5 watt solar panel for long enough, any solar battery would end up fully charged. Just make sure that your battery has enough capacity. Otherwise your solar panels wouldn’t generate enough energy. There needs to be enough capacity in your battery to last the night.
