New member.

I would appreciate advice on the following situation. Placing a 12 X 20 X 10 foot modular shed on a remote piece of property.
We have the option to run power but the cost is significant. $4000.00

We would like to run the following.
Overhead light in center of building (simple)
Flood light on exterior corner of building.
Small heater from Home Depot that stands on the floor.
The cabin will only be occupied on occasional weekends.
Roughly how much would it cost for the system to power this set up with a solar system.

Southeastern climate: Full sun.

Thanks for the help.

If you are going to try to heat with solar electric then you will spend a lot of money. Best to heat with propane or wood.

Somewhere I have a link to a great solar thread on another forum. I'll try to add it this evening.

I have a 14 X 24 cabin for occasional weekend use. I use 2 X 15 watt solar panels/charge controller($175 total from Cabelas) and 2 X 100 Amp-Hour deep cycle marine batteries($100 each). I have numerous lights with 40 watt bulbs, outdoor light, fan on my propane heater, plus bigger air fan for summer, and a small vacuum cleaner that all can be powered by my 400 watt inverter($60) and one battery lasts a good 3-4 days while the other is recharging with the solar cells. I wired up standard wall receptacles plus a porch mounted receptacle that I backfeed from my inverter or small 1000W generator if I need it.

For occasional use, check out
It is a portable system you can load up with 2 deep cycle batteries. You should be able to get a weekend out of them. You can also charge them through this system from your generator. When your done for the weekend, load it up take it home and recharge your batteries for the next weekend. FYI, make sure you change your lightbulbs to the "green" bulbs available everywhere. 14 watt bulbs give the same light output as a standard 60 watt bulb. That's 1/4 of the usage, and every watt counts when running from battery.

You can get a self contained solar powered light for the corner of the building at most hardware stores, its a security floodlight. as for single interior center light there is one available from Northern Tool, yep I'm a big fan of them, check my other postings haha. here ya go, nice light.
