So, you established how much solar power you need for your RV/boat and now want to choose the **solar panels** that fit your space. As I said before, **it is advisable to buy modules with the same nominal power** and, possibly, from the same brand. **This way, you overcome the compatibility issue and the possible loss of power because of mismatching effects in your system.**

**Choosing the right number of solar panels with the right nominal power and size for your RV/boat** could be a little bit tricky. You should also **consider the fact that you may want to expand your system** in the future, so **you might need some extra space**. In that case, **a module with a higher wattage**, instead of several small ones, **could be a better choice**.

## What is the most important size factor?

**The size of the solar panels**, having the same nominal power, **changes slightly** from one brand to another. **The most important factor for the size**, other than its nominal power, **is the type of panel**; by which **I mean either rigid or flexible panels**.

**The rigid solar panels** could be divided into:

**Polycrystalline (multicrystalline)****Monocrystalline**

The **monocrystalline panels are usually more efficient**, which means they are slightly **smaller in size**, in comparison to their **polycrystalline counterpart**, for the same amount of nominal power. The better efficiency also makes the** monocrystalline panels more expensive**.

**The performances** of both types of solar panels are influenced by the **operational temperature**.

**Flexible solar panels**, also known as **thin-film panels**, are known to be **very lightweight** but come with **some downsides** that make them less appealing to buy – they** cost much more** compared to rigid panels, **degrade faster** and have a **shorter warranty** period.

There are, however, some notable** advantages** that could make them a better choice in some cases – they are** lightweight**, **flexible** and **can be installed more easily**. Also, their **performance is not affected by the operational temperature**.

## Rigid solar panels size and weight (30 W to 90 W)

Even though for an **RV or a boat solar power system** you typically want to start to look from 100 W panels upward, but **for those who really want to start small**, I gathered a list (below) starting at 30 W panels.

50 W rigid solar panels are between 1.6 to 1.8 ft (49 – 55 cm) wide and 1.9 to 2.2 ft (58 – 67 cm ) tall.

The average weight is around 9.7 pounds (4.4 kg) for polycrystalline and 9 pounds (4 kg) for monocrystalline types.

I noticed that, for **50 W panels, there are lots more brands from which you can choose**. So, you may get a** better deal** there. The sizes within each wattage rate are almost identical, but there are **some exceptions**, like number fifteen on this list, which has a long, narrow shape.

## Rigid solar panels size and weight (100 W to 200 W)

Now, this is the range of solar panels that are **often used to set-up an off-grid, solar powered system**. **100W are the most common ones**, with various brands and price ranges from which you can choose.

100 W rigid solar panels are between 1.7 to 2.2 ft (0.5 – 0.67 m) wide and 3.3 to 4.3 ft (1 – 1.3 m ) tall.

The average weight is around 18.2 pounds (8.2 kg) for polycrystalline and 15.7 pounds (7.1 kg) for monocrystalline types

## Flexible solar panels size and weight

**The most common choices that we have in this category are 50 W and 100 W panels**. As you can see from the chart, below, there are also **semi-flexible solar panels** that are **more robust** and consequently **weigh more**. They are usually **a better option for marine applications**.

## Conclusion

Keep in mind that choosing **the most efficient solar panel**, which obviously** costs you more**, is not as important as carefully selecting other system components. **A smarter choice is to have an overall balanced system** that pays for itself in the long run.
