Measure Sunlight with a DIY Solar Radiometer

Here are some things to consider when choosing your systems voltage: The DC system voltage is established by the battery bank in off-grid systems. A major factor in making this decision is how much power will be required from the batteries. As power demands increase it is advisable to raise the battery voltage one because of less resistance but a major consideration is you should not put more than 2 banks in parellel of batteries and never more than 3 on one charge controller. This voltage is important because establishes the type of charge controller and inverter that will be selected. The selection of the battery bank voltage affects the currents. A watt off-grid system operating at 12 volts draws amps. The same system draws only 25A at 48 volts.

Solar Panel System: How to Build a Cheap One

I only use this one for charging D cell batteries, and it can take a good 8 hours, more or less depending on the state of charge of the battery, to charge up D Cell NiMH batteries. Again, if you are just starting out, get the Powerex above and the Sanyo Eneloop batteries, if you really must have D cell batteries than get the batteries above and this charger.

It’ll make a good backup AA charger for you as well in case you break, bash, smash, flood your other one. There are some mAh 9 volts on Amazon, but I don’t want you to buy them. They will hold the charge the longest so you might be able to use them in an emergency without having to charge them up first.

DIY Electric Motorized Bicycle To this day I have not found a better diy electric bicycle conversion with all the benefits of this one. It certainly adds loads of fun to an otherwise normal bike ride. Speed and range are dependent on drive wheel and bicycle wheel dimensions among other variables. For more information on how this motorized bike was designed, see: See latest post HERE.

For starters, you will need a bicycle, preferably with lockable front suspension if any and enough room on the front fork tube for two 1. A small strip of non-slip grit tape on the drive wheel will ensure traction in wet weather. Almost everything with the exception of the arbor and U-bolts can be found on an old or damaged Razor E scooter. Early progress photo Video! By request, here is a short video I compiled using old clips of the motor mounting process: On my motor, the four mounting holes were measured to be about 92mm by 42mm apart.

Also, I had to file a tiny bit off the outer curve of one U-bolt to get it to fit into a tight spot without any unnecessary stress on the front fork assembly.

Installing a Solar Panel to Maintain Batteries

But the truth of the matter is — solar energy is an investment. There is a big one time upfront investment for the company that will usually pay off later. You would do the same thing — invest in a pile of components that will become your personal utility.

If you select to hire a contractor to install your solar kit, you should expect to pay approximately $ per watt for labor, wire, conduit, fittings, breakers and other miscellaneous electrical components to complete the solar system installation.

DIY Above Ground Solar Pool Heater Installation Posted on March 9, by Martin June 27, Pool owners around the world have always struggled with the high costs of maintaining comfortable pool temperatures early and late in the swimming season. This is especially tough for above-ground pool owners since the pool is not as well insulated as in-ground pools. Exposed to the outside air on all sides except for the floor, aboveground pools can lose heat more easily than in-ground pools.

If you battle this heat loss with an electric or gas heater, heating the pool comes at a great expense. There is however, a much more affordable alternative — a solar powered pool heater. Solar pool heaters do require more room than a compact gas or electric unit. However, with good installation and placement, solar heater panels are just as out of sight as any other heater — plus they pay for themselves with the savings in heating expenses!

Aboveground Solar Panel Installation The installation of an above-ground solar pool heater involves three steps: Building the rack Plumbing connections Building a Solar Panel Rack The rack is very useful in a solar pool heater application.

DIY Running Board Lights / Ground Lights

To find out how many amps your panels produce, simply look on the label or read the spec sheet. This allows for excessive power generation caused by “edge of cloud” effects. For example, you have 2 panels and they each produce 9 amps. Together that is 18 amps. You should look for a charge controller that rates at a minimum of 25 amps.

I know that was quick and brief but hopefully it gives you an idea of what our set up looks like and how it works. As you see we have two 65 watt solar panels for a grand total of watts.. Our solar power setup isn’t perfect and can be improved providing more power.

Solar Radiation Battery wiring diagrams The following diagrams illustrate how to get increased current more power by using parallel wiring and how to increase voltage levels by using series wiring. You can do both using series and parallel wiring in combinations. Use parallel wiring to increase current power. This diagram shows a simple parallel circuit to increase current or power. Assume that we are using 12 volt batteries.

The power of all 3 batteries add to give us the effect of a battery 3 times as powerful but the voltage stays the same at 12 volts. Parallel wiring increases current but the voltage does not change. This is the wiring used when jump starting a car for example. Use series wiring to increase voltage This diagram shows a simple series circuit to increase the battery voltage level.

Assume that we are using really big 4 volt industrial batteries. The voltage of all 3 batteries add to give us the effect of a battery 3 times the voltage or in this case a very large 12 volt battery.

How to Replace Your Own Furnace

All of our products can be shipped via UPS! Worst case design conditions occur when solar is off. The isolation and drain valves allow the system to be isolated and drained winterized so the pool pump can be run through freezing conditions. These drains should be located at the lowest points in the plumbing and all piping including the bottom headers of the solar panels should slope tilt towards those drains so the water runs out by gravity.

The check valve prevents the water from running backwards through the filter backwashing it when the pool pump is shut off.

Nov 03,  · solar power – how to hook up and how to get PAID? I have 2 questions regarding solar power. The general stuff, I’m going to make an outside gazebo and would like to put solar .

Remove Stake Piece of the Light Remove the stake piece of the solar lights so you are left with the top solar panel piece. I kept the plastic casing around the light because it has a metal reflector that helps intensify the brightness of the lamp. Next, remove the stake part of the light. It should just slide right off. You’ll be left with the solar panel and light component. I kept the plastic casing around the LED. Wrap the foam tape around the solar light. Grab the jar and unscrew the lid. Remove the flat part of the lid and just keep the ring.

The top part of the solar light should slide through the ring nicely with a little bit of snugness. In order to make sure the light doesn’t fall down into the jar, you’ll need to put the foam tape around the top of the light. This will keep it snug. Squeeze the Light into the Center of the Lid Squeeze the light into the center of the lid so it’s mostly flush with the top of the jar.


What types of panels does Make It Right Solar use? We have also used a Lumos module with a clear backsheet. Back to Top Do you have a preference? It depends on the project. Smaller roofs need higher efficiency panels.

How portable do you want your solar generator to be? Think about how heavy and large it should be? Are you going to use a hand truck to carry around a huge toolbox filled with batteries and a large solar panel or do you want a tiny one that will fit in your glove box? The wiring and concept will be the same for either size so the choice is yours. I wanted something in between that I could carry but still had some decent capacity to do some work.

The Container First I bought a case that would be a good jumping off point that I could fit a 10 watt solar panel on and in. Here you can see the 10 watt solar panel is removable and attached with velcro on metal strips.

Below you will find a graph outlining the major players in the Mobile Wifi world and what they offer. You may notice we omitted some names. We did so on purpose because many others only exist while using the below companies cellular towers under a different marketing name and offer very little real value to the end user. Some of them only operate regionally and tend to be uncompetitive on price. If you happen to find a company offering better deals with the same level of service quality, support, and value as what we are describing here than we applaud you!

Just be sure to check the fine print.

without a campsite hookup. For simple battery maintenance or full-time live-aboard power, RV Solar Power Kits are available in a variety of sizes and can be installed on RVs.

Air is harder to keep warm than water, and while most of us need a shower on a hot day—we tend to want space heating when the sun is not doing enough for us. Nevertheless, from a Mad Max style partially solar heated home , through a DIY solar heater from old campaign signs yeah, politics and hot air Here the folks at Fair Companies present one Seattle man’s attempt at heating his home studio with soda cans. The video was shot on a phone, so please pardon picture quality. Because the studio was off-grid, electric space heating was not an option.

So he set up a simple soda can space heater, using fans running off his solar panels to help channel the air. Putting a panel that relies on convection on a relatively flat roof was probably not the smartest of ideas. But once the installation was complete, he does feel like even on a cold, cloudy day he is getting a head start on heating the space compared to the ambient temperature outside. Full instructions on building a solar space heater here.

I’d love to hear from anyone with ideas on how to improve this design.

Who can use Solar Power? A Solar Power energy system can be used by anyone to supply all their electrical needs, provide back-up power, or even just as a supplement to the normal electrical grid connection to a utility company. It is ideal for remote locations where power is unavailable or too expensive to hook-up to.

DIY Instructions. Diagrams and Videos RV Solar Education Benefits Of Solar Volts, Amps, Watts you could see a shorter payback period with your RV system than you would with a residential solar system, only because full hookup camp sites charge you for a lot more than the value of the utility power you consume. An RV power system will cost.

You can use the SSSM to monitor seeing conditions through the day, or even to control your camera to capture images during the best seeing conditions. I have also re-factored the Arduino sketch to make it more modular and readable. The SSSM uses a silicon photo-diode to measure the intensity of sunlight falling on it.

As daytime seeing is dominated by air turbulence close to the ground, the photo-diode must be mounted close to the aperture of your solar telescope. The SSSM consists of five main components: A simple amplifier circuit to convert the tiny current generated by the photo diode in to measurable voltages. An Arduino board to convert the voltages into data.

All you really need to know is that sunlight hits the photo-diode at the left of the diagram, and a couple of voltages come out of the connections at the right. These are then measured by an off-the-shelf micro-controller board and results sent to your computer. Most importantly of all a patient, methodical approach will get you over any minor obstacles. Equipment List You will need the following equipment: A soldering iron with a fine tip and solder.

A multi-meter for checking your soldering is OK.
