How can I increase the autonomy power of my motor home?

In a camper electricity and water are precious. We must therefore learn to save without depriving the indispensable.

To increase its autonomy, for example, you can install a solar panel. Who stays a week in the same place needs to find a way to recharge the batteries, and a good solution is the solar panel.

Be aware that they are expensive and fragile, just the branch of a tree to break, and is an additional weight.

We also need to park in the sun, if you parked in the shade not serve. If we want to increase the autonomy of our campers we can increase the number of panels.

Estimate the Total Power You Need

Get a pen and notebook. List every electrical device: each light, all chargers, TV, washer, dryer, microwave, A/C, etc.

List the wattage used next to the item, and indicate whether they are AC (alternating current) or DC (direct current, as in battery powered). Make two columns if you need to. List how long each device is used and multiply the hours used by the wattage to get the daily total used.

Add the total current needs in each column, and the total needed overall. Although this may seem daunting at first, it really is easy to do.

Decide if you want to run the items directly from the solar photovoltaic system or if you’ll use the system to charge a battery bank first then use the power. Those appliances labeled as AC will need an inverter to accept the DC power directly from the batteries. Inverters are available for individual appliances or for entire AC systems.

What and how should I install the solar panels on my camper?

A photovoltaic system area is based on:

• One or more photovoltaic panels
• A charge regulator to measure voltage and current
• A battery.
• 1 Mounting kit
• 1 Display light to see the different levels of solar energy
• 1 Parallel to keep the battery engine charged after the service battery is loaded from solar
• 1 Set of cables to connect the panel on the roof and maintai an excellent insulation against the infiltration of water from the roof.

How can I calculate the real power of a panel?

To calculate the power and let it work nearly 100% we need to consider:

1. Intensity of solar radiation (sunshine). The highest value is obtained only in exceptional weather conditions and practically never in real situations.
2. Temperature of 25 ° C but we all know that in a day of exceptionally high sunshine for sure the temperature is above 25 ° C. Higher temperatures cause a decreasing of the performance of the panel.
3. Incidence of perpendicular sunlight.

Calculate Your Total Power System Size and Cost

Calculate your total RV photovoltaic power requirements by using the following information located at: http://www.energysavers.gov/pdfs/208.pdf, and the following formula:

By using the correct incline of the rooftop panels, you can easily calculate how much energy can be collected and the correct number of panels needed for your RV.

Sound hard? Not really.

Let’s say, for example you’re going to stay in Arizona. A single 200-watt solar panel could provide you with 16,000 watts of power every day (with 8 hrs sunlight). Using your wattage total for your appliances (i.e., 80,000 watts/day) you’ll need a total of 5- 200 watt solar panels. The total cost for those will be $3,475.

How many solar powered panels?

Example 1: Big motorhome then big consumer

• Using 2 lights, refrigerator, TV, VCR, etc.
• Having 3 evenings of autonomy in summer, 2 nights in winter
• Power panels: 140 watts with adjustable solution
• 180 watts with non-adjustable

Example 2: Average consumer

• Power: 90 watts with adjustable solution
• 110 Watt not adjustable

Example 3: Small consumer mini camper

• 50 Watt power adjustable
• 65 Watt not adjustable

What’s the right wattage for caravans to run lights, TV etc?

In choosing the type of panel you can follow the following guidelines:

• 80 watt panel: It ‘a small plant, ideal for those who use the camper mainly in the warmer months and not use auxiliary utilities such as CTV or fans.
• 125 watt panel: The ideal solution for those who use the television.
• 140 watt panel: It represents the best solution for anyone, making use of summer vehicle, stopping long ago and wants to have a good availability of power for various accessories.
• 2 panel of 125 watt: The choice we recommend to all those who have a refrigerator compressor, or make an intensive use, even in winter.

Get an Estimate on Energy Savings and Payback

The economic benefits of an RV photovoltaic power system are easy to figure. Total how much in electricity costs you spend on your RV each month or as a year total.

Divide that figure into the cost for your system. This is the estimate of how long it will take the system to pay for itself. Keep in mind that this is a base figure. It doesn’t take into account the cost of electricity from one county or state to another. Since electricity costs are rising, you can easily estimate the payback time while you use your RV and enjoy free energy at the same time while using a notebook with “savings to date” listed.

How to install the solar panels?

The ideal would always have the sun perpendicular. This is achievable only with a rotating and tilting variable, but this is not always possible.
