DIY Solar Water Heater. A Homemade “flat panel” COPPER COIL Solar Water Heater. Easy DIY. Full Instructions. super hot temps (sustained at 165F+). fast hot water. no electricity needed. easily hooks up to standard water tap/garden hose. reaches temps well over 150F (water pasteurization temp) so it works to clear/kill any pathogens (if a non-municipal source is used). it’s super portable so it’s good for camping/off-grid/emergency as well as everyday use. couple of notes: water flow rate verified with a measuring cup and a stopwatch. (roughly 1 oz. of hot water every 1 to 1.5 seconds and scaled up – one gallon every 2-3 minutes or 20-30 gallons per hour). about the copper tubing: a 50 foot roll of tubing is much cheaper than smaller rolls connected. *only $24.95 for 50 ft (but $17 for a 20 ft roll and $10 for a 10 ft roll). the glass is just standard window glass and the paint is flat black. it’s thin flat design allows it to be easily stored in a closet, under the bed etc… *”seal it” according to your climate conditions and whether you plan to leave it outside.
UPDATE: (06/01/2018)… if interested, here’s a youtube video link to my other (most current) copper coil water heater. It’s of a similar design but is lined with aluminum sheeting and uses larger diameter coil.

shows how to hook up solar panels (with a battery bank). simple instructions. home solar power station. very easy to put together. all you need is 1 or more batteries, an inverter, charge controller and a solar panel or panels. the following is for a 12 volt system. use one ‘deep cycle’ battery for every 2 to 6 amps your panels generate. (batteries like to be charged at this rate). a 12 volt 1 amp panel generates about 15 watts. you can use any solar panels. if you can’t get the smaller panels then buy one larger one. (Kyocera sells an inexpensive 7-8 amp solar panel (135 watter)). that would go perfect with 2 deep cycle batteries. the six panels in the video are from harbor freight tools. i bought 2 three panel sets. they sell the panels in sets of three or individually. coleman sells similar panels. the batteries are from walmart. they are ‘deep cycle’ batteries. the charge controller is from fry’s electronics. the inverter is from harbor freight tools. this system will provide all the ‘free’ power you will need to run tons of things around your house. i’ve posted 6 videos showing all sorts of things running on this system (computers, tvs, stereos, lights, power tools, appliances, and more). all can be found on my youtube channel homepage. great little system to start with. try ‘powering up’ one room in your house. you now have a solar assisted house. as one example; this could easily run a light, laptop computer, fan and small tv for several hours every day. also great in an emergency, power outage, remote and rural off-grid living.

In this project I will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. And at the end I will show you the energy harvest difference between a solar tracker mounted solar panel and a flat mounted solar panel.

You can get individual solar cells here (affiliate link):

In this episode of DIY or Buy I will show you how I created a 100W solar panel by myself. Along the way you will learn how to wire up solar cells and how they are usually wired up in a commercial solar panel. At the end we will then evaluate whether the DIY version is cheaper to produce.
