This video shows the build of a DIY solar powered, pressurized, roof top water heater and shower.This is done using an ABS 4 inch pipe, 6 feet long, which would give me a capacity of 15 Litres or 4 US gallons.This is an easy and inexpensive project that required minimal tools and just some basic plumbing parts.I started by installing the shutoff valve. I wanted the drain to be as low as possible in the pipe to avoid necessity of having to tilt the system. To ensure the valve retaining nut did not interfere with the pipe once it is glued into the, I positioned the nut away from the wall of the cap using a bolt, which is the same thickness as the wall of the pipe.I drilled out a 2” threaded cap and tapped in a radiator valve drain plug that I picked up at the local automotive parts store. This valve will allow me to release pressure from the tank should that be necessary without opening the drain shutoff. Also when open, this will allow a gravity fed system through the drain valve should for some reason I not have access to the air compressor.As a final step to improve thermal absorption of solar energy, I painted the surface with flat black paint. First I lightly buffed all the ABS surfaces with steel wool soaked Methol Hydrate. Then applied one coat of spray primer followed by two coats of flat black paint.
- DIY Video:How to build a simple Off Grid Electricity Generation System using Two BatteriesThis project shows you how to generate Off grid AC Power using a simple Solar power station with 2 batteries.This system can provide enough off the grid power to run your appliances around the house.You can easily run light,a laptop computer, small tv and fan for several hours. Most of the item required can be bought from your local store or Amazon.The rough cost of building this system is as follows : $150 for 100W Solar Panel $75 each for 2 batteries. $20 for 400w Inverter $40 for charge controller. The whole system comprises of four things, a couple of batteries, inverter, and a charge controller.The inverter is purchased from Harbor freight ,the charge controller from fry electronics.The deep cycle batteries are from Walmart. So you start by setting up your panels outside. In this case, I have six one amp panel set up, 15 watts a panel, so that's 90 watts coming in. I lead them straight down to the main connection, it's just the six black wires all connected together and twisted tightly to that extension cord wire and the six red ones connected.Feed the line into your house,goes straight to the charge controller. The output wire from the charge controller goes into the battery.So solar panels to charge controller ,charge controller to lead battery in your bank.And as you want to expand this to two,three or more batteries, just use some automotive cables and go from positive terminal of one the positive of the other. And with a black wire, negative terminal to negative terminal, the other one. When you want to run something, just get your inverter that converts the power from DC to AC, take the clamps, clamp them onto that same lead battery in the system. So again, red to the positive side, black to the negative side and flip it on. So remember, when you hook things up like an inverter, or the charge controller or voltmeter, anything you're going to hook up on here, make sure you always pick one of the batteries to be the lead battery and hook everything to that. Whether you parallel one extra battery with it, or five or six or however many you want to put on there. Also added here is a lighted voltmeter which gives you a constant reading on your battery bank so you know exactly what's going on with it at all time. https://www.youtube.com/watch?v=cgEvCLJuBkg https://www.youtube.com/watch?v=8LAjx_XAR90 A simple system that can come really handy during a power outage or in any emergency situation.
