Ditch the noisy, smelly and pollution creating portable generator when you travel off the grid in your RV, boat or camper. It’s not only more eco-friendly, it’s handy when camping where there’s no electrical hookup. Solar Panel Kits are the clean way to power your tiny house, shed or cabin.

Article Overview

What Are The Benefits Of Going Solar?

Many small solar power kits aren’t much more expensive than a generator. Sure, a generator may not require the same level of installation, but there are many benefits of using solar power for your tiny house, RV, boat or camper. These include:

  • Clean, renewable energy source
  • Freedom to roam and go off-the-grid
  • Extend your battery life by 50%
  • Quiet and safe alternative to generator use
  • Backup power for emergencies

By going solar, you’re helping to reduce the demand for fossil fuels and to limit greenhouse gas emissions.

Solar power also helps reduce such air pollutants as nitrous oxides, sulfur dioxide, and particulate matter emissions that contribute to chronic lung and heart health problems. So, do yourself, others and the Earth a favor by going solar.

How Does A Solar Panel Kit Work?

Solar cells in a solar panel convert the sun’s energy into DC (direct current) electricity, which then travels as a current to the 12V deep cycle battery via a conducting wire. The battery stores this current as amperage, which combines with the battery’s voltage to produce power.

Solar power kits are an excellent way to keep your RV’s in-house 12V battery charged and to run certain appliances you’ll need (lighting, water pump, etc.). And if you want to run AC-powered devices (ones that plug into a wall outlet) like a TV, small microwave or hair dryer, you can purchase a power inverter. The inverter converts your battery’s DC power into AC household power.

Many small solar panel kits come with (almost) everything you’ll need to power up, but most don’t include the necessary 12-volt deep cycle solar battery. Prices for these batteries range anywhere from $50 to $250+. Some kits come with inverters, which can significantly jack up the kit price. But you could find a kit with an inverter that’s a better deal than purchasing an inverter separately (inverters average about $65).

Monocrystalline vs Polycrystalline Panels

As you’re looking into solar panel kits, you’ll likely notice that you often have a choice between monocrystalline or polycrystalline panels with some products. What’s the difference? Monocrystalline panels are smaller and more energy efficient. Polycrystalline panels use more resources to produce, are larger and not as energy efficient.

The catch? Monocrystalline panels are typically more expensive, but better manufacturers are closing the gap on the pricing difference. In most cases, we recommend going with monocrystalline panels if your budget allows.
