What Components Of Solar Kits Do You Need?

There are components of a solar kit that you can install on your caravan. There are also various kits to choose from.

Renogy has tailored these kits to meet your peculiar energy needs. We have four major kits with their various features and benefits.

1. Caravan Solar panel kits

Renogy caravan kits are designed to connect you to a power supply in your motor house or any other mobile application. This kit has components suitable for mobile projects, including cable housing units and mount charge controllers. These make installation very easy.

Caravan kits are easy to use and offer comfort for your travels by eliminating noisy generator sounds.

You can install caravan kits on your mobile rooftops. That protects them from being stolen when you are up and about, away from your caravan. You can quickly recharge your batteries with them no matter the weather condition.

Their installation process leaves your rooftops free from holes and leaks. You can position the solar panels at an angle that maximizes energy production and increases performance by up to 40%. The caravan solar kit is so efficient it allows you to run your refrigerator all day and night.

We, however, recommend that you use a DC refrigerator for better-regulated power consumption.

Key features

• Efficient Solar Panels: The solar panels incorporated into the caravan kit are specially designed for off-grid systems, caravans, greenhouse systems, boats, and other mobile applications. With its bypass diodes, this kit can utilize the sunlight available in low-light and shaded environments to generate excellent energy outputs. You can easily install the panels on any top surface.
• 30A DC-DC: The caravan kit can charge all service batteries originating from two DC inputs, be they solar, alternate, or combined. It maximizes solar energy with its inbuilt Maximum Power Point Tracking (MPPT). It utilizes a 3-phase charging profile to charge your service batteries to full capacity using the appropriate voltage levels. You can set the caravan kit up with smart alternators because of its inbuilt Voltage Sensitive Relay (VSR). This kit is compatible with both smart and traditional alternators. With its temperature and voltage compensation features, this kit offers you prolonged battery life spanning many years.
• Smart protection features:
• Overheat protection
• Battery isolation
• Reverse current protection
• Alternator reverse polarity protection
• Over-voltage protection
• Battery temperature protection
• Over-current protection
• Solar panel reverse polarity protection

2. Starter Kits

With a starter kit, you can take your initial steps at being independent in power generation. This kit suits people trying out caravan solar systems for the first time, and it contains all the necessary components to generate energy in your caravan.

You can get a starter kit in 30W-400W, and they are flexible for you to use anywhere as you begin your solar adventure.

The starter kits comprise:

• Solar panels
• Adaptor kits
• Charge controller
• Battery
• Tray cables
• Power inverter

The primary essence of a starter kit is to recharge and monitor your 12-volt battery bank. With a starter kit, you should not run your DC loads independently of the solar panels or controller. Instead, connect all your DC loads directly to the 12-volt battery bank included in the kit.

The starter kit also utilizes a Pulse Width Modulation (PWM), which controls how the energy generated in the solar panels is distributed to charge the batters, leading to the higher efficiency of the solar system.

Key features of starter kits

• Efficient: Starter kits are very efficient. They have high solar monocrystalline cells. Starter kits can also ensure excellent power generation and system performance in shaded and low-light areas.
• Reliable: Starter kits are also reliable. They comprise EL-tested solar modules; hence they don't have hot spots. They include aluminum frames which makes them resistant to rust. That makes them a good choice for extended outdoor use. They can last for decades on your caravan without corroding. They are protected from outdoor elements and low-pressure water jets, thanks to the IP65-rated junction box included.
• Intuitive: Starter kits are well sealed; hence they can produce energy even in flooded environments.
• Safe: Starter kits from Renogy are multiple layers of protection to guard against short-circuiting, reverse polarity, and overcharging. They are also secure and won't fall off your caravan after installation because they are well-fastened via the pre-drilled holes on the back of the panels.
• Expandable: The Renogy Wanderer 30A PWM Charge Controller offers system expansion of up to 400W

Some products in our starter kit category include: 

3. Complete Kits

Complete kits suit people with mini RV fridges, electronics, outdoor lighting, and LED lights in their caravans. The complete kit can power these electrical appliances and fittings so you can enjoy added comfort in your caravan.

Complete kits comprise:

• 100W flexible monocrystalline solar panels
• charge controllers
• DC-DC Battery Charger with MPPT technology
• Lithium batteries

Tips To Get the Most Energy Out Of Your Solar Panel Kit

When you finally lay your hands on a caravan solar panel kit, you want to ensure that you get the most energy from your investment. Interestingly, there are a few measures to get the optimal performance from your kit.

Here are a few tips to help have the best of your caravan solar:

1. Ensure to position your solar panels in such a way that they can maximize exposure to sunlight. Place them to face the sun directly. Keep them away from tree shades and other obstructions as much as possible.

2. Tilt your solar panels at ideal angles, depending on your location, to help optimize their efficiency.

3. You should clean your solar panels regularly to avoid the buildup of dust, debris, dirt, and reduced efficiency.

4. Constantly monitor your solar panel system to ensure it performs optimally. Endeavor to check for loose connections or damaged panels if you notice reduced energy generation.

5. Ensure to take proper care of your caravan's battery system. Keep it charged and in good condition always. 

6. We recommend using LED lights and energy-saving appliances to minimize power usage in your caravan.

7. Learn to manage your energy efficiently. When lights and appliances are not in use, you should turn them off. Also, prioritize your energy consumption so as to better utilize the energy available to you.

8. Consider consulting a solar professional like Renogy to ascertain the best caravan configuration correctly. If need be, you can add more solar panels to your current system if you are not getting enough power output.

Different Types of Solar Panels

1. Monocrystalline Solar Panels: These types of solar panels are dark colored. They are more efficient in power generation and performance. They are, however, expensive, though the best option for people who value excellent output.

2. Polycrystalline Solar Panels: These types of solar panels are light blue colored. They are less efficient than the monocrystalline type. They are, however, cheaper and a better option for people on a tight budget.

3. Rigid Solar Panel: It comprises both monocrystalline and polycrystalline cells. It also has an aluminum frame and a protective tempered glass layer. The rigid solar panel is the commonest solar panel available for purchase. Renogy's rigid solar panels range between 30 and 200 Watts.

4. Flexible Solar Panels: These panels from Renogy comprise durable polymer material that makes them thin and light, a characteristic that makes them the most suitable choice for rough surfaces. Flexible solar panels for caravans are also perfect.

5. Folding Solar Suitcases: This type of solar panel is made with the same materials as rigid solar panels. They are suitable for configurations that have limited space available. 

Can You Go Fully Off-Grid With Caravan Solar Panels?

Yes, you certainly can go entirely off-grid with caravan solar panels. You can join many other persons who install solar panels on their caravans and depend solely on them to generate electricity while they travel or camp in a remote location. With caravan solar panels, you can produce healthy renewable energy for your appliances, lighting, and recharging needs.

What Size And How Many Solar Panels Do You Need?

To ascertain the number of solar panels you need, you should first get the product of your pane's wattage and the number of peak sun hours. You thereafter divide your daily energy usage by the result of your first calculation.
