How much a 200 watt solar panel can power depends on a number of variables including the time of year, the weather, your location and the type of charge controller you install. But here's an idea of what you might expect to get on an average day of 4 peak hours of sun with an MPPT controller. A 200 watt panel will. A 200 watt solar panel set up is relatively small. Unless you intend wild camping in your motorhome, you may have reliable access to shore power. With economical use, you may not. There's a few points worth clarifying about this wiring diagram before you get into the detail: 1. The wiring diagram shows only the supply side installation of a 200 watt solar. This is a list of every componentyou need for a 200 watt solar panel set up on your RV or campervan. If you'd prefer to avoid shopping around, you can buy pre-configured solar panel kits. They usually include the solar panel, solar charge controller and mounting brackets. Some include extension wires. If you opt to buy a solar kit, check what's included and what additional things you'll need to buy. And make sure it makes economical sense.
[PDF Version]The diagram also excludes wiring a power inverter – it sits on the load side of the battery. The 200 watt solar panel wiring diagram assumes 2 x 100w panels are being fitted. If you happen to be fitting 1 x 200w panel instead, see our 100 watt solar panel wiring diagram. We've included 2 diagrams below.
How much a 200 watt solar panel can power depends on a number of variables including the time of year, the weather, your location and the type of charge controller you install. But here's an idea of what you might expect to get on an average day of 4 peak hours of sun with an MPPT controller.
The wiring diagram shows only the supply side installation of a 200 watt solar panel system. It goes as far as charging the battery. For the load side detail, check out our post on campervan wiring. It excludes charging the battery from shore power or the alternator. For information on how to fit the battery, see our post on campervan batteries.
A 200 watt solar panel set up is relatively small. Unless you intend wild camping in your motorhome, you may have reliable access to shore power. With economical use, you may not even need to hook up. Because a 200 watt set up can run a small energy efficient fridge, it's a good size for small campers.
A 200W solar panel setup could generate at most, around 16ah of power per peak hour. However, how many peak hours of sun you can reasonably expect to receive differs by location, time of year and the weather. In the US, you're unlikely to get much more than 5 or 6 hours of peak sun conditions in mid summer.
A 20A controller is adequate for a 200 watt solar panel set up. If you think you may want to scale up your solar capacity in the future, consider buying a higher rated MPPT solar charge controller because it'll be more cost effective in the long term. Check out our complete guide on how to select the right solar charge controller for your setup.
